Rotary Trommel Screen is a kind of mechanical screening equipment widely used in separation operations. The material separation is controlled according to the particle size of the material, and the separation precision is high.
The cylinder of the circular sieve is generally divided into several sections, depending on the specific situation. The meshes are arranged from small to large, and the diameters of the meshes on each section are the same.
Rotary Trommel Screens are widely used for precise grading and separation of wood chips, soil, compost, solid waste, domestic waste, ore, rock and aggregate.
The rotary drum screen is mainly composed of a motor, a reducer, a drum device, a frame, a sealing cover, an inlet and an outlet.
How does Rotary Trommel Screen work ?
The cylindrical drum is mounted obliquely on the frame. The motor is connected with the roller device through the reducer, and drives the roller to rotate around its axis.
When the material enters the Rotary Trommel Screen, due to the tilting rotation of the drum device, the material on the screen surface is turned over and rolled, so that the qualified material is discharged through the discharge port at the bottom of the drum, and the unqualified material is discharged through the discharge port at the end of the drum.
Due to the turning and rolling of the material in the drum, the material stuck in the sieve hole will be ejected to prevent the sieve hole from being blocked.Some related videos, you can also check our Instagram videos.
Advantages of Rotary Trommel Screen
- The principle of rolling conveying, the friction coefficient is small, and the screen hole is not easy to be blocked.
- The roller frame adopts an integral through-shaft structure, which runs smoothly, without vibration and with low noise.
- The accessories of the internal rotating cheese screen adopt split design, the structure is simple, and the replacement and maintenance are quick and convenient.
- The roller device adopts an effective fully sealed structure, free from dust and pollution.
- Safe and reliable operation. Adopting the reducer, the transmission efficiency is high, the belt power is small, the energy consumption is low, and the energy-saving effect is obvious.
- Round screen manufacturers choose different screen materials according to different needs of customers to prolong the service life of the trommel screen and reduce maintenance costs.
- Adopt special sieve, high screening efficiency and long service life.
- The main frame of the heavy steel structure is designed with components that reduce material accumulation.
- The trunnion assembly is mounted on heavy-duty roller bearings for long life.
- The installation inclination angle is small, and the screening effect is good.
- The portable Rotary Trommel Screenis flexible and suitable for small and medium thickeners that need to be moved.
