Trommel Screen
Special wear-resistant steel screen is adopted, which has high screening efficiency, long screen life (more than 3 years) and low cost of spare parts.
The rolling conveying principle is adopted, with small friction coefficient, light wear, and self-cleaning function. It can screen wet materials with large moisture content, and the screen hole is not easy to block.
Product Description
Trommel screen, or rotary screen, is a kind of mechanical screening machine which is widely used in the separation operation. It controls the material separation by the particle size, and the separation precision is high. The cylinder of the trommel screen is generally divided into several sections, depending on the specific situation. The mesh holes are arranged from small to large, and the mesh hole diameter on each section is the same.
It is suitable for screening all kinds of mineral and chemical materials, as well as coal, coal gangue, coke, quicklime and other damp and easily clogged materials. The maximum particle size of the screened products is 80mm, the middle is 10 ~ 50mm, and the smallest is less than 3mm
WORKING PRINCIPLE
The cylindrical drum is mounted obliquely on the frame. The motor is coupled to roller device via the reducer and drive the drum rotates around its axis.
When the material enters the drum screen, due to the inclination and rotation of the roller device, the material on the screen surface will turn over and roll, so that the qualified material will be discharged through the outlet at the bottom of the drum, and the unqualified material will be discharged through the outlet at the end of drum.
Due to the overturning and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from blocking.
FEATURES
1. The rolling conveying principle is adopted, with small friction coefficient, light wear, and self-cleaning function. It can screen wet materials with large moisture content, and the screen hole is not easy to block.
2. Roller support design, using the whole through shaft structure, stable operation, with low power, obvious energy saving effect. The internal drum screen and other spare parts adopt split design, with simple structure, convenient replacement and maintenance, economic and fast.
3. The roller body adopts effective full sealing structure, no dust, low noise, civilized production can be reliably guaranteed. The operation of the whole machine is safe, stable, reliable and vibration free. It is driven by high efficiency reducer with high transmission efficiency.
4. Special wear-resistant steel screen is adopted, which has high screening efficiency, long screen life (more than 3 years) and low cost of spare parts
