​HOW IT WORKS
A True Screening ™ system, Gyru-Star screening buckets separate material without crushing, tearing or shredding.
HOW GYRU-STAR WORKS
FLEXIBLE POLY-STARS FOR NON-DESTRUCTIVE SCREENING
Gyru-Star screening buckets use rotating flexible poly-stars to separate material. As the stars rotate, they create a tumbling action inside the bucket, which causes the undersized material to fall through the gaps between the stars.
​
The screening aperture, or gaps between the stars, can be adjusted by using a different size fragment kit. These are available in 4 different sizes, from 10-40mm. As the polyurethane stars are flexible, they can screen material without crushing, shredding or tearing. This enables Gyru-Star screening buckets to be used for far more than just separating material, making them a highly versatile attachment for any kind of carrier.
The poly-stars also work exceptionally well with wet or sticky material, such as clay-heavy soils. As a result, you can keep working no matter the weather, which isn’t always possible with other kinds of screening equipment.
​
ULTRA-RELIABLE CARBON BELT DRIVE
Most poly-star screening buckets currently on the market still use chain drive systems. Not only are these drivelines loud, but they also require daily oiling and greasing, with the chains being prone to stretching.
To minimise downtime from maintenance, and maximise reliability, Gyru-Star screening buckets utilise an innovative and ultra-reliable carbon belt drive systems. As well as being self-tensioning, this system requires zero lubrication, eliminating the need to daily greasing and oiling.
​
‘PLUG AND PLAY’ HYDRAULIC SYSTEM
​
Gyru-Star screening buckets are hydraulically powered and are run from the carrier's auxiliary hydraulic circuit. Depending on which model you are using, the hydraulic flow rate with vary, though the hydraulic pressure is consistent across all models in the range (200 BAR).
Designed to be a ‘plug and play’ system, Gyru-Star screening buckets are ready to go from the moment they arrive on site.
For carriers without the option to control the flow rate, Gyru-Star screening buckets can be supplied with flow control valves. These can be fitted to any Gyru-Star screening bucket and enable the operator to manually adjust the flow rate. These flow control systems are supplied as standard with all skid steer specific models (SL range).
​
FRAGMENT SIZES FOR EVERY APPLICATION
The size of the product the bucket produces is dictated by the fragment size. Simply put, this is the size of the gap between the poly-stars. Gyru-Star buckets are available in 4 different fragment sizes, 0-10mm, 0-20mm, 0-25mm and 0-40mm. For applications where the fragment size needs to be reduced further, comb kits are also available. When ordering your Gyru-Star screening bucket, you will need to specify your required fragment size. However, if your needs change, then the fragment size can easily be changed.
INDUSTRY LEADING FEATURES. AS STANDARD
Gyru-Star Compact Screening Systems come standard with a full compliment of industry-leading features.
WHY CHOOSE A GYRU-STAR SCREENING BUCKET
A Gyru-Star screening bucket might be the best investment you ever make for your business. Here's a few reason why!
LOW MAINTENANCE​
The the low maintenance design reduces downtime by eliminating the need for daily maintenance.
Sealed bearings are used throughout, and the carbon belt drive requires zero lubrication.​
FAST AND EFFICIENT​
The large screening area and poly-star rotors maximise the output of the bucket. Screen material directly where it is needed and combine screening, loading or backfilling into one single operation.​
QUIET OPERATION
The internally routed carbon belt drive keeps noise to a minimum. This makes Gyru-Star screening buckets ideal for noise-sensitive jobsites, such as residential areas.
REACH ANY JOBSITE
Gyru-Star screening buckets can go anywhere your carrier can, from urban demolition sites with limited access, to remote infrastructure projects miles from the nearest road.
Unlike tracked or static screeners, Gyru-Star screening buckets can be easily transported on the same trailer as your excavator or loader, with most 2 and 3 rotor buckets fitting in a standard truck bed.
SCREEN MATERIAL RIGHT WHERE IT'S NEEDED​
With a Gyru-Star screening bucket, you can screen material right where it's needed, using machinery you already have on the jobsite.
Not only does this speed up the screening process, but reduces equipment, fuel and operator costs.
AFFORDABLE AND COST EFFECTIVE​
Gyru-Star screening buckets are an affordable alternative to tracked and static screeners.
The comparatively low purchase cost, coupled with minimal maintenance and ease of transport, make Gyru-Star the No.1 choice for professionals seeking a fast, yet affordable screening solution.
"SCREENS THE WET LIKE THE DRY"​
These aren't our words, but those of numerous Gyru-Star customers around the world. Thanks to the non-stick stainless steel floor, and flexible poly-star rotors, Gyru-Star screening buckets are effective even in wet conditions.
This also makes them an excellent choice for screening clay-heavy soils and other sticky materials.
