The tension of the drum screen belt loosens the screw between the gearbox and the motor

For macroporous materials, it is recommended to use perforated screens (aperture larger than 5mm). There is a big difference in the production process between the mesh and the mesh. The perforated plate is round, and the interface butt joint is more integrated and easy to manufacture. The plate can be made of stainless steel 304 and porous, which is more durable. The woven mesh is made of round steel with the same wire diameter. When the material is too large or too heavy, it is easy to deform and leak. The interface is also difficult to strengthen, and the manufacturing is complex and expensive.

Roller screen inverter:

Reverse frequency conversion during forward rotation is prohibited, which will result in more severe short circuit of the motor and deformation of the main body of the shutter screen. In the process of frequency conversion, reduce the speed to make the screen stationary, and then reverse the frequency. In addition, the selection of inverters should be based on good products.

Drum screen standard socket:

The advantages of roller screen are high discharging speed and high precision. However, the design of the outlet is also important, and material blockage often occurs. It is suggested that the angle should be vertical to the ground, and the diameter should be large to facilitate the smooth output of materials.

 Roller screen

Roller bearing maintenance:

The two positions of the front shell and the back shell of the selenium drum screen are the key. The entire drum and drum material are placed in the bearing housing. Bearings are more important. Pay attention to the wear of the bearing or whether there is noise in the production. Replace in case of emergency. In addition, lubricants should be added to the lubrication points of the equipment on a regular basis.

Regularly check the tightening of bolts of gearbox and motor

The tension of the roller screen belt looses the screw between the gearbox and the motor. Be sure to check the tightness of bolts and belts to avoid slipping.

Drum screen has high efficiency, small amplitude and high frequency. Different from the principle of ordinary screening equipment, due to the high frequency of high-frequency screening, on the one hand, the surface tension of slurry and the high-speed oscillation of fine particles on the screen surface are destroyed, and the density (specific gravity) of useful minerals and separation are accelerated. This effect increases the contact probability of the material to smaller than the separated particle size and mesh size, resulting in better separation conditions, thus making the material with smaller particle size (especially larger particles and slurry) become smaller products through the mesh.
