Trommel screen

PRODUCT INTRODUCTION

The trommel screen controls waste sorting by the size of particle diameter, with high sorting accuracy. It is widely applicable for the grading of large and small stones in stone yards, the separation of soil and stone powder, the separation of sand and gravel in sand yards, the separation of lump coal and coal powder in the coal industry, and coal washing (as a component of coal washing machines). It is also used in the chemical and mineral processing industries for grading large and small lumps and separating powdered materials. The machine boasts high reliability, high screening efficiency, and excellent filtration results, with no dust or noise pollution during the production process. It is a widely used mechanical device in sorting technology.

ADVANTAGE

1.  Excellent screening effect. The finished screen adopts a strict installation angle, making the screen holes less prone to blockage, resulting in an excellent screening effect and high screening efficiency.
2.  High sorting accuracy. The inner wall of the drum is equipped with flexible plates, which lift material particles, allowing particles of different sizes to have the opportunity to contact the screen holes as much as possible, effectively improving sorting accuracy.
3.  Centralized lubrication, fast and convenient. An advanced centralized lubrication system is adopted, making lubrication convenient and quick, with minimal maintenance workload.
4.  Good sealing, environmentally friendly.The screening drum can be enclosed, making it easy to achieve dust containment. The drum is covered by a dust-proof sealing cover, ensuring that the production process is almost free of dust and noise pollution.

WORKING PRINCIPLE

The drum device is tilted and mounted on the frame. The motor is connected to the drum device via a coupling through a reducer, driving the drum device to rotate around its axis. When materials enter the drum device, the tilting and rotation of the drum cause the materials on the screen surface to tumble and roll. This allows the qualified materials (undersize product) to be discharged through the outlet at the bottom of the rear end of the drum, while the unqualified materials (oversize product) are discharged through the outlet at the tail end of the drum. Due to the tumbling and rolling of the materials inside the drum, any particles stuck in the screen holes can be ejected, preventing screen clogging.
