Shaftless trommel screening machine

Shaftless trommel screening machine is more defined by shaft trommel screen. It is mainly composed of electric motor, reducer, roller device, frame, outrigger, safety sealing shield, feeding hopper, unloading hopper, discharging hopper, etc. It is suitable for screening decoration waste, domestic waste, construction waste, obsolete waste, stone, coal, slag, slag and other materials and particles.

Working principle:
The roller device is supported by four polyurethane rollers and installed on the frame at an inclination of 6-8°. The motor is connected with the roller device through the reducer, the roller and the roller device through the coupling, and the roller device is driven to rotate by friction. When the material enters the drum, due to the inclination and rotation of the drum device, the material on the screen surface is turned and rolled, the qualified material (under-screen product) is discharged through the screen hole of the drum, and the unqualified material (over-screen product) is discharged through the end of the drum . By changing the pore size of the screen and the length of the screen section, the multi-stage screening of materials (small first and then large) can be achieved. Due to the turning and rolling of the material in the drum, the material stuck in the sieve hole is ejected to avoid the blockage of the sieve hole. In
addition, a vibrating hammer can be installed in the sieve cylinder to prevent clogging, and a hard brush or whipping device can be installed outside the sieve cylinder to prevent clogging.

Features:
1. Shaftless design to avoid entanglement of large soft materials.
2. The drum speed is adjustable by frequency conversion, which increases the safety of equipment operation.
3. The overall inclination of the sieve drum is 6-8°, the screening efficiency is high, and the processing capacity is large.
4. Polyurethane friction rolling transmission, low energy consumption (4-37kw) and low noise.
5. It can be customized environmental protection fully enclosed type or mobile type.
6. Garbage screening can prevent garbage from falling to the ground.
