The Maintenance of Cyclone Separator and PU Screen Plate

2021-05-22

Cyclone separator and polyurethane screen are the main components of the fine sand recovery units. As the fine sand recovery machine is in operation, the cyclone separator and the polyurethane screen panel are worn out, so daily maintenance and maintenance are indispensable.

1. Choosing the right material for cyclone

According to the size and use conditions of the silt separator and polyurethane sieve plate of the fine sand recovery machine, the material of the cyclone separator and the polyurethane sieve plate is reasonably selected for the fine sand recovery machine. For sediment separators and polyurethane sieve plates with a processing capacity of less than 50t/h, materials that have a certain toughness and are dominated by high hardness should be selected. For the 50t/h cyclone separator and polyurethane sieve plate, high-toughness and high manganese steel should be selected to make the hydro cyclone separator and polyurethane sieve plate. For large-scale crushers 100t/h and 150t/h sediment separators and polyurethane screens, high-toughness materials must be selected, supplemented by other comprehensive performance manufacturing materials.

2. Repairing the wear of the separator in time

When the separator and polyurethane sieve plate of the fine sand recovery machine is worn out, they can be repaired by surfacing welding with a manganese steel electrode. During the surfacing welding process of the top of the silt separator and the polyurethane sieve plate, a reinforced hard alloy can be introduced into the surfacing metal, or a new type of resistant hard alloy made of chromium iron-carbon and iron powder relying on a plastic binder can be used. The surfacing of grinding materials.

3. Improving the utilization rate of separator and polyurethane sieve plate

During the operation of the fine sand recovery machine, attention should be paid to the change in the diameter of the cyclone’s sand settling port. When the sedimentation opening increases, the number of sedimentation increases, the mass fraction decreases, the fine particles in the sedimentation increase, the overflow flow decreases, and the overflow becomes finer. Conversely, when the tearing sand opening decreases, the sedimentation mass fraction increases, the coarse particles in the overflow increase, and the overflow flow increases.

The change of the sand settling port can be judged according to the spray angle when the settling sand is ejected, and the spray angle is generally 40°～70°. If the sedimentation is discharged in a rope shape, it means that the sedimentation port is small, and the sedimentation mass fraction increases at this time. If the settling sand is ejected in an umbrella shape, it means that the settling port is large, and the mass fraction of settling sand is greatly reduced at this time.
