The main features of the shaftless drum screen

1. Simple installation foundation: Because the entire equipment is a box-shaped frame structure, only a flat ground is required. The ground is hardened and easy to clean. 2. High integrity: Except for the finished material stacker belt conveyor, all systems are integrated in an overall frame, which not only ensures the integrity of the equipment, but also leaves moderate maintenance and inspection space. Convenience and safety.

3. Easy to disassemble and transfer: the high integrity of the equipment is convenient for construction site storage or transfer transportation. The only disassembled parts are the finished product stacker belt conveyor. Loosen the bottom fixing bolts and the hanging wire rope, and insert the finished belt conveyor into the main frame. The bottom surface is fine.

4. Working reliability: The core screening system adopts the mixing principle of a mixer. The raw materials are rolled and pushed by continuous spiral blades and friction between materials in the mixing drum, which has a strong effect and high reliability.

5 The rolling screen is placed flat, and the material flow is screened more than five times between the spiral blades of the screen, so that the sand material is repeatedly rolled and fully separated and screened. It is different from the phenomenon of ineffective screening and mixing caused by the squeezing of large and small materials caused by the inclined rolling screen or the inclined vibrating screen or the vibration of large and small materials.

The shaftless roller screen motor is connected with the roller device via a reducer through a coupling, and drives the roller device to roll around its axis. When the material enters the drum equipment, due to the skew and tumbling of the drum equipment, the material on the screen surface is turned and rolled, so that qualified materials (products under the screen) are discharged through the screen on the outer circle of the drum, and unqualified materials (products on the screen) ) Discharge through the end of the 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 being blocked.
