On river dredging sites, when dealing with materials mixed with pebbles and sediment, or piles of waste on construction demolition sites, how can we quickly recycle valuable materials? Traditional fixed screening lines not only require high investment but are also limited by site conditions. At this time, an excavator equipped with a rotary screening bucket can become an efficient mobile screening station to solve separation problems directly on site. This kind of screening attachments for excavators that integrates hydraulic drive and rotary screening is changing the processing mode of earthwork projects.【WhatsApp/WeChat/Phone】+86 13837122632

Working Principle of Rotary Screening Bucket
The working principle of rotary screening bucket is simple but highly efficient. It is powered by the excavator’s own hydraulic system to drive the screening drum to rotate at high speed.
- Material loading: The excavator bucket is filled with mixed materials to be processed, such as pebbles containing sediment or crushed construction waste.
- Centrifugal screening:With the high-speed rotation of the drum, fine materials smaller than the screen mesh (such as sand and small stones) are quickly thrown out of the drum by centrifugal force, falling to the ground or a designated stacking area.
- Retention of coarse materials: Stones, concrete blocks or other debris larger than the mesh size are retained inside the drum. The operator can transfer the screened coarse materials to another area for complete classification under hydraulic screening.
- The whole process is smooth without stopping for material replacement, realizing instant separation of materials.
Advantages of Rotary Screening Bucket
Compared with traditional manual screening or fixed machinery, hydraulic screening bucket has unparalleled on-site advantages and greatly increases the value of your excavator.
- Versatile and extremely flexible
It is not only a screening bucket but also a mixer, cleaner and feeder. Whether for demolition material screening, landfill material classification, river sediment cleaning or natural stone separation, it can be adapted by replacing screens with different apertures, without renting expensive special screening equipment.
- Sturdy structure and long service life
Designed for harsh working conditions, the rotary screening teeth and internal protection are made of wear-resistant steel with excellent weldability and wear resistance. Equipped with high-quality stainless steel screens, it ensures a long service life even when handling sharp crushed stones or corrosive materials, reducing downtime for replacement.
- Reasonable design and efficient anti-clogging
The unique structure ensures stable operation. Its self-cleaning mechanism effectively prevents screen blockage when handling wet or sticky materials, with better adaptability than vibrating screens. Screen specifications can be selected according to material size and are easy to replace, greatly reducing machine wear.
- Improved quality, cost reduction and efficiency increase
Direct screening on the construction site means impurities can be removed immediately to obtain pure recycled aggregate for backfilling or paving. This not only saves transportation and disposal costs of waste but also reduces the cost of purchasing new materials, making it an ideal tool for green construction.
How to Further Improve the Screening Efficiency of Rotary Screening Bucket?
With a good attachment, operating skills also determine the final productivity. Master the following tips to maximize your equipment’s potential.
- Control feeding speed
Avoid shoveling too much material at one time. Maintain a continuous and uniform feeding speed to ensure enough space for materials to tumble and separate in the drum. Overfilling will cause material accumulation and reduce screening effect as materials are dumped before separation.
- Assist with boom movement
During screening, properly use the up-and-down swing of the excavator boom. This changes the stacking angle of materials in the drum and increases tumbling opportunities, especially for slightly sticky materials, effectively accelerating fine materials passing through the screen.
- Adjust rotation speed according to materials
Different materials require different rotation speeds. Use the recommended high speed for dry and easy-to-screen sand and gravel. For wet and agglomerated materials, properly reduce the speed to extend material retention time in the drum, achieving better separation with tumbling motion.
- Keep the site level
Level the working area before operation. This protects the excavator’s traveling mechanism and creates good conditions for stacking finished screened materials, facilitating subsequent loading and use.
Daily Maintenance of Hydraulic Screening Bucket
Like all hydraulic attachments, the service life of hydraulic screening bucket is closely related to daily maintenance. Regular maintenance not only prevents sudden failures but also significantly reduces long-term operating costs.
- Check the screen daily
Before and after operation, check whether the screen is damaged, loose or excessively worn. The screen is a wearing part; timely replacement of damaged screens ensures screening accuracy and prevents internal structure damage from large materials.
- Clean debris regularly
After daily work, remove flexible debris (such as plastic bags, tree roots, steel bars) wrapped around the drum spindle or support plates. These residues affect the dynamic balance of the drum and accelerate bearing wear.
- Lubrication system maintenance
Strictly follow the maintenance manual to regularly add grease to rotating parts such as bearing seats and universal joints. Also check for leaks in hydraulic pipelines to ensure heat dissipation and cleanliness of the hydraulic motor.
- Tighten bolts
Due to strong vibration during work, regularly check and tighten all connecting bolts and flange screws to prevent structural deformation or damage caused by looseness.
