Sijojimo kaušas, sorteringskopor, sieblöffel, třídící lžíce and Seulakauha are all different names used for screening buckets around Europe. Regardless of what it’s called, there is one common question we get from those who are unfamiliar with this type of product. “What exactly is a screening bucket, and what does it do?”   To answer this question, we’re going to take a look at the following:  What is a Screening Bucket?  What are Screening Buckets Used For?  What are the Different Types of Screening Bucket?  How to Choose the Right Screening Bucket for My Excavator or Loader?  What is a Screening Bucket?  Screening buckets are attachments for excavators and loaders, which are designed to separate materials of different sizes. Some screening attachments crush and shred material as well, whilst other buckets like the Gyru-Star range, are non-destructive. Screening buckets come in a range of sizes, with models commonly available for carriers from 1 to 30 tons. Gyru-Star’s range of screening buckets covers this entire range, from the smallest 2-50E for 1-ton excavators, all the way up to the 6-150MAX for 20 to 30 ton excavators and 10 to 15 ton loaders. What are Screening Buckets Used For?  Screening buckets have a wide range of applications, ranging from recycling construction waste to aerating compost, though different types of buckets will have different uses. Here’s a few of the applications which Gyru-Star Screening Buckets have been used for:  Aerating compost and topsoil  Mixing and blending aggregates  Screening biomass material  Cable and pipeline padding  Recycling construction and demolition waste  Recycling road scrapings for resurfacing  Removing rocks, roots and other impurities from soil  What are the Different Types of Screening Bucket?   There are various different types of screening buckets currently available on the market. Though they generally fall into one of two categories. Destructive and non-destructive. As the focus of this article is on non-destructive screening solutions, we will be taking a look at two of the most common options for non-destructive screening.  Rotary Type Screening Buckets These buckets use a rotating steel basket, which is full of holes of a set size. As the basket rotates, it creates a rolling action, causing the smaller material to fall through the holes. However, as the holes are a fixed size, a new basket is required to change the fragment size. Whilst the rotary buckets can be very gentle on the material, they are often very inefficient, and cannot work in wet, sticky material such as clay. On the other hand, they do generally perform well when screening aggregates. Poly-Star Screening Buckets  Poly-star screening buckets have quickly become the number one solution for non-destructive screening. Gyru-Star is the market leader in this sector and is the world’s largest producer of screening buckets. One of the main advantages of poly-star screening buckets is that they screen material without crushing, shredding or tearing. Furthermore, some screening buckets, like those from Gyru-Star, are available with multiple fragment-size kits. This allows the operator to adapt the fragment size to the task at hand. Additionally, poly-star buckets tend to be quieter than their steel counterparts. This is ideal for noise-sensitive sites, such as those in urban centres and residential areas. How to Choose a Screening Bucket for Your Excavator or Loader? There are a few important factors to consider when choosing a screening bucket for your carrier, including the application, type of carrier and the weight capacity. Gyru-Star offer models to suit a range of carriers, from 1 ton mini-excavators to 15 ton wheel loaders. The E, HE, HDX and MAX ranges are designed primarily for excavators, though some HDX and MAX models can be adapted for use with loaders as well. The L range is designed especially for loaders. This includes compact loaders and tractors, telehandlers and backhoes. The SL range, on the other hand, has been designed specifically for skid steer loaders, such as those from Bobcat. Gyru-Star’s range includes models to suit carriers from 1 to 30 tons, so there is sure to be a screening bucket to fit your existing carriers. You can find out what the appropriate carrier weight is for each model, by visiting the corresponding product page. If using a Gyru-Star screening bucket with a tilt rotator, then it may be necessary to use a lighter bucket, due to the additional weight of the tilt rotator. One of the biggest advantages of Gyru-Star Compact Screening Systems is their versatility. Their non-destructive screening capability means that the same bucket can be used for anything from aerating compost to recycling demolition waste. However, different applications will require different fragment sizes. For example, if you are aerating compost then a 0-40mm fragment kit may be most suitable. For backfilling cable and pipe trenches, a 0-10mm fragment kit may be required.

Key Information Bucket: Gyru-Star 4-150MAX  Carrier: Atlas 160W with Tilt Rotator  Application:  Recycling material on a road laying project  Location:  Fjärås, Sweden  Dealer:   MTT Sweden AB  The Case Study Nils-Erik Skantze, of machine contractor Skantze Entreprenad, is currently working on a road laying project in the town of Fjärås, Sweden. With an increased importance being placed on recycling materials, Nils-Erik has been looking for ways to efficiently process materials on-site.  It was this which led to him purchasing a Gyru-Star 4-150 MAX from MTT Sweden AB, Gyru-Star’s official Swedish distributor. However, since taking delivery of his Gyru-Star screening bucket, Nils-Erik has discovered various other advantages.  The biggest of which he says, is being able to screen soil and aggregates in place, rather than having to move them across sites to be processed in a large screening plant.  “It's nice not to have to drive material back and forth between the houses in the area,” he told MTT Sweden AB. “Now I can do the screening myself thanks to the sorting bucket”.  Nils-Erik is currently using his 4-150MAX screening bucket with an Atlas 160W wheeled excavator, for backfilling and grading on a road resurfacing project. However, it has proven so versatile that he now brings it to every project he works on.  “It is the best investment I have made. The more I use – the more uses I find for it. During the season, I always have it with me”  The capabilities of the Gyru-Star screening bucket are not all that impressed Nils-Erik. He also talks very highly of the supplier, MTT Sweden AB. “They are incredibly committed to their customers. After purchasing the bucket, they followed up with calls and checks, to see how things were going. You are not used to such good service”. Gyru-Star’s MAX screening buckets are fitted with a longer cutting edge, reinforced with Hardox for abrasion resistance. This makes it easier to fill the bucket from smaller stockpiles and also enables it to be used as a planning bucket.  You can find out more about the Gyru-Star MAX series, and our full range of screening buckets here .   Thank you to MTT Sweden AB for providing us with this case study.

Key Information Date: Spring 2021 Dealer: S.J. Pigg Plant Repairs Location: Northeast England, UK Model: Gyru-Star 4-100HE Carrier: Kobelco SK 75 SR-7 Excavator with a Rototilt RC3 Tilt Rotator Application: Recycling crusher waste into drainage stone How a Gyru-Star 4-100HE Saved the Day on a Remote Construction Project While many Gyru-Star customers initially purchase their screening buckets for a specific task or application, their versatility means that operators soon find new uses for them, even those most of us might not normally think of. One customer, a farmer in Northeast England, found exactly that during a construction project on their remote farm. Early on in the project, they purchased a Gyru-Star 4-100HE, from S.J. Pigg Plant Repairs, their local Gyru-Star dealer. The customer originally sought a screening attachment for their Kobelco SK 75 SR-7 excavator, to improve soil quality around a new farm building. When collecting their new bucket from S.J. Pigg, they commented that they probably wouldn’t use the bucket too much. However, this was not to be the case! The day before the concrete foundations of the new building were due to be poured, they hit a problem. Whilst finishing a drain, they realised that they had depleted their supply of clean single-size drainage stone. Being late in the day, there was not enough time to go and collect more material. To make matters worse, the rural location of the site meant that there was no phone signal, preventing them from ordering more for delivery. Thankfully, the customer had their Gyru-Star 4-100HE screening bucket on hand, which had a 20mm fragment kit installed. Using the bucket on their Kobelco SK 75 SR 7, they were able to process waste crusher run from a previous project into drainage stone. The Gyru-Star bucket made short work of turning the waste material, separating the material without crushing shredding or tearing. This left the customer with two piles of usable material, from what would otherwise have been waste. The pile of >20mm material was used as drainage stone, allowing them to finish the project on time and save on additional material costs. Furthermore, the customer also utilised the <20mm, using it on the building’s floor to flatten out the uneven surfaces. This case study is a testament to the versatility of Gyru-Star Compact Screening Systems, and an excellent example of how they can save you and your business money. Thank you to S.J. Pigg Plant Repairs for this case study.

What is Biomass? The term biomass refers to the natural, biological material, which is used as fuel for things like electricity production or heating. Forestry Research describes biomass as being predominantly plant-based material, such as forestry waste. However, food waste is also commonly used. The waste material is incinerated, and the heat is used to generate energy for electricity and heating. This is also a common method for disposing of waste which would otherwise go to landfill. In some cases, biomass material can also be converted into fuel.  Why Does Biomass Need to be Screened? To get the highest possible amount of energy from biomass material, any impurities or non-organic material first need to be removed. This is especially important in the production of liquid and gas fuels. Furthermore, automatic biomass systems require the material to be a uniform shape and size. To use the example of woodchip, a common by-product of the forestry and arboriculture industry, the chip would need to be separated from any leaves, mulch or rocks, which may be mixed into the material. What Are the Options for Screening Biomass?  There are currently plenty of options on the market when it comes to biomass-specific screening plant. These machines are typically static or large tracked machines.   Common Options for Screening Biomass  Trommel Type Screeners  Disc Screens  Static Screens  Flip-Flow Screens  Whilst many of the machines above can quickly screen considerable amounts of material, there are several drawbacks, especially for smaller contractors, such as tree surgeons, forestry contractors, landscapers and other land-based industries.  Drawbacks of Traditional Screeners  They can require quite a lot of space.  Increased fuel costs. Can require additional machinery and operators to load material.  Difficult to transport, in some cases requiring HGVs.  Can only be used for processing biomass material.  Purchase costs can be prohibitively expensive.  Additional maintenance and servicing costs.  Many of these systems crush and shred material when screening.  It is in this instance that screening buckets present a unique solution, ideal for independent contractors and smaller operations.  Gyru-Star Compact Screening Systems  Gyru-Star Compact Screening Systems are the marketing leader in the compact screening sector. Their poly-star rotors screen material without crushing, shredding or tearing, making them ideal for processing materials such as woodchips for biomass.  With fragment sizes available from 10-40mm, and models to suit carriers from 1 to 30 tons, Gyru-Star screening buckets allow you to maximise the efficiency and versatility of your excavator, loader, tractor, backhoe, telehandler or skid steer loader.  Benefits of Gyru-Star Compact Screening Systems  Fast, efficient screening across the entire range.  Low maintenance with a carbon belt drive system and sealed bearings throughout (won’t contaminate the material with oil or grease either).  Reduce fuel and operator costs by using your existing machinery.  ‘Plug and play’ system reduces downtime.  No crushing, shredding or tearing of the material.  Screen material anywhere the carrier can go.  Doesn’t waste valuable space on site or in your yard when not in use.  Lower purchase cost than other types of screener.  Where Can I Buy a Gyru-Star Screening Bucket?  Gyru-Star Compact Screening Systems are available from a worldwide network of authorised dealers. There are currently dealers in the UK, Europe, Asia, Australia, New Zealand and North America.  To find your nearest dealer, visit the ‘dealer finder’ page linked below.  In the unlikely event that there is not an authorised dealer in your region, or you are thinking of becoming a dealer yourself, get in touch with our team for more information.  Email: sales@gyru-star.com   Telephone: +44 (0)1452 728448

Gyru-Star Compact Screening Systems have long proven a popular choice for professionals in the utility industry, as a fast, efficient solution for backfilling cable and pipe trenches. In this article, we will be taking an in-depth look at the MAX series, and how it has been designed as a purpose-built tool for this application. We will be looking at: Where did the demand for a backfilling bucket come from?  An introduction to the MAX series.  Key features of the MAX series.  What are the benefits of using a Gyru-Star screening bucket for backfilling cable trenches?  Where to buy a MAX series bucket.  Where Did the Demand for a Backfilling Bucket Come From?  The MAX series of screening buckets was born from a conversation between Wheatway Managing Director, Colin Smith, and Gyru-Star’s Swedish distributor, MTT Sweden AB . At the time of development, there had been considerable investment in renewable energy in Sweden, which resulted in widespread infrastructure projects. Predominantly the laying of long-distance cable routes between the country’s scattered population centres and new wind and solar farm projects. This led to demand for a new screening bucket, purpose-built for the needs of the contractors on these vast cable and pipe laying projects.  In order to protect vulnerable cables and pipes, regulations dictate that they must be surrounded by padding material. Usually, this means material under 10mm in size, although this can vary depending on the region and application. With many projects taking place in remote or wilderness areas, where there may be no road access for several miles, bringing in new padding material by truck could be difficult and expensive, if not impossible.  In addition, even on projects in perfectly accessible areas, contractors are looking for ways to cut costs. Being able to process trench arisings into padding material is a major cost saver when laying cables or pipes, especially when you can use the same carrier which dug out the trench initially.  Intro to the MAX Series This is where Gyru-Star Compact Screening Systems come into their own. Easily transportable, and compatible with a wide range of carriers, they offer operators a fast, efficient screening solution which can be used on remote or hard-to-access sites.  Whilst the HE and HDX series were (and remain) firm favourites for processing trench arisings, a dedicated solution was still desired, in order to maximise the capabilities of existing carriers. As a result, Wheatway Solutions started the development of a new bucket with a wider cutting-edge and longer floor pan. Originally part of the HE and HDX series, this new product soon evolved into the MAX series of screening buckets. Key Features of the MAX Series  As with all Gyru-Star screening buckets, the MAX series is equipped with all the standard features which customers have come to expect, and which, have set the industry standard. These include: A non-stick floor for processing wet or clay-heavy material.  Key wear areas are reinforced with Hardox abrasion-resistant steel to increase durability.  Flexible poly-stars for screening material without crushing, shredding or tearing.  Low maintenance, ultra-durable carbon belt drive.  Sealed bearings throughout, to eliminate the risk of material contamination.  Multi-layer monocoque shell perfectly balances weight and strength.  Sizes to suit a wide range of carriers from 1-30 tons including excavators, tractors, loaders, telehandlers and skid steers (depending on series and model).  Bespoke head plates and interfaces to suit almost any carrier, through the Kustom Konnect sister brand.  In addition to the standard features of the Gyru-Star range, the MAX series has been engineered specifically for backfilling over cables and pipes. The cutting edge of the bucket is much wider than the other series, giving the bucket a shovel-like shape. Coupled with a longer floor pan, filling the bucket from smaller stockpiles becomes much easier. This is ideal for processing trench arisings, which are generally piled alongside the trench, rather than in large stockpiles. What are the Benefits of Using a Gyru-Star Screening Bucket for Backfilling Cable Trenches?  So what benefits are there to using a Gyru-Star Screening bucket over traditional methods for backfilling cable and pipe trenches? What makes them the ideal tool for the job? Cost-saving The main benefit which has been fed back from Gyru-Star customers is the cost-saving potential. As the Gyru-Star screening bucket allows for waste material to be recycled, the need to purchase new, pre-screened material is eliminated.  Similarly, the transport costs associated with moving large volumes of material are also eliminated. Even if the material could be processed elsewhere on site, with a traditional screening plant, there is still a considerable time and monetary cost to moving it particularly so on large developments or infrastructure projects.  Space-saving and Ease of Transport  This in turn also raises another key benefit of the Gyru-Star screening buckets, which is simply that they require less space than a screening plant. This also applies to transport, with some models in the range being small enough to fit in the bed of a standard pick-up truck. Larger models are easily transported on the same trailer as their carrier, again reducing transport costs.  Remote and Hard-to-Access Sites  For remote and hard-to-access sites, Gyru-Star Compact Screening Systems are ideal. Able to go anywhere the carrier can, they do not pose the same logistical issues as a screening plant.  This has been a major benefit for operators in Sweden, who have been regularly working miles from the nearest road, in the depths of the Swedish wilderness. Where road access is limited, project costs can skyrocket, and progress can be slow. Gyru-Star screening buckets allow for trench arisings to be processed in place, using the same carrier which originally excavated the trench, keeping project costs low and progress on track.  Reliability and Low Maintenance  When working on projects in remote areas, having reliable, dependable equipment is of the utmost importance. Gyru-Star screening buckets have been designed to be as reliable as possible, whilst keeping maintenance to a minimum. With sealed bearings throughout, there is no need for greasing and oiling. Not only does this decrease downtime for maintenance, but it also reduces the risk of material being contaminated by oil leaks or over-greased bearings. The rotors of the Gyru-Star screening buckets are driven by carbon belts, and as such, require no lubrication. This is a stark contrast to many competing products, the majority of which rely on outdated chain drive systems, which sit in enclosed oil baths. The simplicity and reliability of the Gyru-Star screening systems is one of the main reasons they have become the first choice for operators working in remote areas. Use Carriers Already On-Site With 30 models across 6 series, to suit carriers from 1-30 tons, Gyru-Star offers the largest range of screening buckets on the market. Whatever carriers you already on have on site, there is almost certainly a Gyru-Star screening bucket to fit. This enables operators to maximise the potential of their carrier, whether it is an excavator, loader, telehandler, tractor, backhoe or skid steer. Reduced Environmental Impact  An often overlooked, but nonetheless important benefit of the Gyru-Star range, is that the buckets can reduce the environmental impact of a project. This is predominately through their ability to reduce fuel usage, the number of vehicles and machines required on-site and the recycling of waste materials.  Where to buy a MAX Series bucket  The Gyru-Star dealer network spans the globe, with authorised dealers in the UK, Europe, US, South America and Asia.
