Excavator Rotary Sieve Bucket

The screening bucket of an excavator is a screening device installed on an excavator. It drives the screen to vibrate or rotate through a hydraulic system, achieving functions such as soil and stone separation and material classification. ‌

Core function

It is mainly used in fields such as construction waste treatment, mining, and farmland transformation. It can simultaneously complete operations such as screening, crushing, and loading, replacing the traditional manual screening method.

Applicable scenarios

Construction waste: Efficiently separate stones from soil to enhance resource utilization. ‌

Mine/farmland: handle tasks such as ore classification and soil purification. ‌

In the field of environmental protection: reduce dust pollution from construction waste and realize mechanized operations. ‌

Structural features

Drum design: The screen is driven to rotate by a hydraulic motor to achieve the classification and screening of medium and fine grade materials. ‌

Vibrating screening: The motor drives the screen to vibrate at high frequency, causing the material to jump and separate (some models support this technology). ‌

Modular design: The mesh size of the screen can be customized (1-15 cm) to meet the requirements of different materials. ‌

Technical advantage

It supports the processing of wet materials, dry materials and mixed materials, and has strong anti-clogging ability. ‌

The structure is compact, the maintenance cost is low, and it can be used for multiple purposes with one machine (such as river sand screening, coal washing, etc.). ‌

The excavator screening bucket is a multi-functional auxiliary device installed on excavators, mainly used in scenarios such as construction waste treatment, sand and gravel separation, and solid material screening. Its core applications include:

Efficient treatment of construction waste

Driven by the power system of the excavator, the screening bucket can achieve the separation of soil and stones, and its efficiency is several times higher than that of traditional manual screening. It is applicable to complex working conditions such as wet soil, dry soil and mixed soil containing stones, effectively solving the problem of construction waste treatment. ‌

Multi-material classification and screening

It is used for ore grading and screening in mining, for removing soil impurities in farmland improvement, and for garbage classification and recycling in urban construction. The screening particle size can be customized. The maximum processed material can reach 15 centimeters, and the minimum can be as small as 100 mesh (for sand screening). ‌

Environmental protection and efficiency advantages

Adopt mechanized operations instead of manual labor to reduce dust pollution and noise interference. For instance, the water-washed screening hopper reduces dust by spraying water or vacuuming, making it suitable for scenarios with high environmental protection requirements. ‌

Quick installation and compatibility

The design is compatible with equipment such as excavators and loaders. Materials are picked up by the operating arm and sent into the screening hopper, achieving "one machine with multiple uses". ‌

The competitive advantages of excavator screening buckets are mainly reflected in three aspects: high efficiency, flexibility and environmental friendliness.

High efficiency

The screening efficiency can reach tens to hundreds of cubic meters per hour, far exceeding manual screening. Its internal comb-type screening mechanism design ensures stable operation even in dirty and impure material environments, and its processing capacity is significantly higher than that of traditional equipment. ‌

Flexibility

It can be directly installed on excavators without additional infrastructure, quickly reaching narrow construction sites or remote areas, achieving on-site screening and significantly reducing transportation costs. The operation training is simple and compatible with various feeding methods (such as belts, funnels, etc.). ‌

Environmental friendliness

Electric drive is adopted to reduce noise and exhaust emissions. The fine materials after screening can be directly used for backfilling or greening, reducing the negative impact of construction waste on the environment. ‌

In addition, the screening hopper has a simple structure and low maintenance cost, and can be used for multiple purposes with one machine (such as river sand screening, construction waste classification, etc.), further lowering the threshold for use.
