The Allu D-Series screener crusher bucket attachment works with wheel loaders, excavators and skid steers to screen, crush, pulverize, aerate, blend, mix, separate, feed and load materials all in one stage. The Allu power adjustment valve promotes powerful startup and rotation allowing the attachment to efficiently screen and crush wet or dry material from 0.60 to 6-in. (1.5 to 15 cm) fragment sizes. Straight side plate construction makes the Allu D-Series screener crusher buckets easy to fill and able to hold a greater volume of material, while the standard power adjustment valve prevents overloads, according to the manuafacturer.
Locating the hydraulics on the back of the attachment keeps them protected from damage, while fender plates protect the bearings and seals. Its patented construction keeps nuts and bolts away from the material flow. Allu D-Series screener crusher bucket attachments are available in more than 60 models to fit any excavator, wheel loader, skid steer or backhoe.
To lower overall usage costs, the Allu screener crusher buckets feature changeable wear hammers for crushing applications. Universal wear hammers are used for most applications and materials. Long wear hammers are recommended for screening and aerating compost and other soft materials to increase capacity. Axe wear hammers are ideal for crushing bark and mixing compost, while oval wear hammers are designed for screening material with high stone content or when reduced crushing effect is needed.
