XCDRS sieving roller series (JB/T 13657-2019)
Screening roller is an indispensable equipment in the mine transport system. It can improve the working efficiency of the crusher and reduce the electrical energy consumption and metal wear of the crusher. The machine has wide adaptability to mines, especially for mines with high moisture, which is not easy to plug up. It has the characteristics of simple structure, stable operation, no vibration, low noise, less dust, large output, energy saving and environmental protection. Sieving roller machine adopts single motor single axis rotation to push the material forward along the roll, and the material is quickly scattered and layered under the characteristics of inclination roll surface and equal thickness screening (feeding section). Particles smaller than the roller shaft clearance by the action of dead weight and roller shaft rotation force, through the gap between the roller shafts (according to the requirements of customized geometric clearance) fall, larger than the roller shaft clearance on the roller shaft surface continue to move forward, fall into the crusher, in order to achieve the purpose of ore feeding and screening.
Structure and main features
The screen type roller shaft machine is mainly composed of a frame, a lining plate, a reducer motor, a roller shaft assembly, a bearing, a bearing seat, a cleaning device, an electric drive bypass discharging device, etc.
1. Uniform accessories, easy to replace and repair.
2. Set up electric drive bypass unloading device for easy material cleaning.
3. The roll is made of special alloy wear-resistant steel, strong and durable, reasonable structure design, assembly, replacement and maintenance are very convenient.
4. Wide adaptability to minerals and working environment, not easy to plug, especially for minerals with high moisture.
5. Add anti-blocking signal, anti-wear plate and cleaning device to play the role of safety protection and anti-blocking.
6. Single machine single shaft rotation (can realize single machine start and stop, one machine alarm protection), with roller motor (start torque is large), the whole roll surface rotation is stable and reliable.
7. The installation direction of the drive device is optional unilateral drive and bilateral drive, which can be made of split type.
8. Roller shaft can be divided into Z type (tooth type roller) and H type (ring type roller), tooth type roller can be customized tooth shape to meet the requirements of different materials.
9. The roll axis is arranged by equithick screening design with inclination Angle, and the roll surface is divided into step structure. The appropriate inclination degree is selected according to the actual situation and use requirements of minerals, so that the "parabolic" trajectory of minerals can obtain better use effect.
10. The overall design is thick, safe and stable operation, low noise, less dust, energy saving and environmental protection.
11. The sieve roll machine has an ideal advantage for solving the floor type installation (resonant response of the building).
