Product Introduction: Rotary trommel screen is a high-capacity, low-operation screening equipment widely used in mining, sand and gravel production, construction waste recycling, coal washing, and bulk material grading. Different from vibrating screens, it adopts rotary drum screening principle with large processing volume, anti-blocking performance and stable operation. It is specially designed for screening wet, sticky, mixed and large granular materials, solving the common problems of screen clogging and low throughput in traditional screening machines. As the core equipment for coarse screening and material classification, it is perfectly matched with large crushing and recycling production lines.

Working Principle

The motor drives the cylindrical screen drum to rotate at a constant low speed. After raw materials enter the drum, they are continuously lifted, tumbled and screened through gravity and rotary friction. Small particles, soil and impurities pass through the screen mesh and fall down, while large stones and unqualified materials are discharged along the rotating drum. Equipped with self-cleaning device, the screen mesh can avoid adhesion of wet and sticky materials, realizing continuous, efficient and stable 24-hour screening operation.

Core Product Advantages

1. Super Large Processing Capacity

Low-speed rotary operation allows continuous feeding and bulk screening. The drum screen area is large with no material dead angle. It is suitable for high-yield production demands and far exceeds the processing capacity of ordinary vibrating screens in bulk material screening.

2. Excellent Anti-Clogging & Self-Cleaning Performance

Unique rolling and tumbling screening method prevents fine powder and sticky materials from adhering to the screen mesh. Matching rolling cleaning device effectively clears blockages, solving the screening difficulty of wet sand, muddy materials and sticky minerals fundamentally.

3. Stable Operation & Low Failure Rate

Low-speed rotary structure avoids strong vibration and impact. The whole machine runs smoothly with low noise and small wear. The transmission system is durable and reliable, adapting to long-term continuous heavy-duty work.

4. Wide Adaptability & Strong Material Compatibility

It can handle dry, wet, sticky and mixed materials efficiently, not limited by material humidity or viscosity. It supports coarse screening, soil removal, impurity removal and graded screening of various bulk materials.

5. Simple Structure & Low Operating Cost

The equipment has a simple and compact structure with fewer vulnerable parts. Daily maintenance is convenient and fast. Low energy consumption and low later maintenance cost greatly save production investment for enterprises.

6. Customizable Design

Drum length, diameter, screen mesh aperture and layers can be customized according to customer materials, output and site requirements. Both mobile and fixed types are optional to meet different production scenarios.
