Core Function ：

Rotating Drum Screen Design: Cylindrical screen drum rotates on trunnion rollers, lifting and tumbling material as it travels through drum length, with undersize falling through screen openings while oversize discharges at end.

Multiple Screen Sections: Drum can be divided into multiple sections with different screen opening sizes for producing multiple products from single feed in sequential screening stages.

Adjustable Inclination: Drum inclination angle can be adjusted to control material residence time and screening efficiency, optimizing performance for different material characteristics.

Internal Lifters: Longitudinal lifters inside drum lift and cascade material for improved screening efficiency and prevention of screen blinding in sticky or clay-containing materials.

Application ：

Topsoil Screening: Screening topsoil to remove rocks, roots, and debris for landscaping, agriculture, and site restoration where rotating action effectively separates materials without blinding.

Compost Processing: Screening compost and organic materials where tumbling action breaks up clumps and separates specification compost from oversize organic matter effectively.

Recycling Applications: Screening mixed construction and demolition waste, municipal solid waste, and industrial by-products where rotating drum handles variable and difficult materials.

Alluvial Mining: Screening alluvial deposits for gold, tin, and other placer minerals where drum screening effectively removes oversize while retaining valuable fine minerals.

Advantage ：

Handles Difficult Materials: Rotating tumbling action effectively screens sticky, clay-containing, and organic materials that would blind conventional vibrating screens quickly.

Simple Mechanical Design: Few moving parts, slow rotation speed, and robust construction ensure reliable operation with minimal maintenance requirements and long service life.

Low Power Consumption: Slow rotational speed and simple drive system consume minimal power compared to vibrating screens of equivalent capacity, reducing operational costs.

Quiet Operation: Low-speed rotation generates significantly less noise than vibrating screens, important for operations in noise-sensitive areas or indoor facilities.
