Maintenance of sand separator in fine sand recycling machine

2019-03-07

Sand separator and polyurethane sieve plate are main components in fine sand recycling machine.Because of the wear of sediment separator in the operation of sand recycling machine, it is necessary to carry out daily maintenance.

First of all, to choose the fine sediment separator manufacturing material

According to the size and using condition of silt separator and polyurethane sieve plate, the material of silt separator and polyurethane sieve plate is selected reasonably for the fine sand recycling machine.

For example, for silt separator and polyurethane sieve plate with a processing capacity below 50t/h, the manufacturing material with certain toughness and great hardness should be selected;For 50t/h sediment separator and polyurethane sieve plate, high toughness and high manganese steel should be selected to manufacture sediment separator and polyurethane sieve plate.For large crusher 100t/h and 150t/h sediment separator and polyurethane sieve plate, high toughness material must be selected, supplemented by other comprehensive performance of the manufacturing material.

Then the sand separator is timely repair wear

When fine sand recycling machine silt separator and polyurethane sieve plate after receiving the wear and tear, can use manganese steel welding electrode welding to repair, on top of the silt separator and polyurethane sieve plate welding process, to introduce reinforcing carbide surfacing metal, also can be used by carbon ferrochrome and the iron powder on the plastic binder made of a new type of wear-resistant overlaying welding material.

Finally, the utilization ratio of sediment separator and polyurethane sieve plate was improved

In the process of fine sand recycling machine, we should pay attention to the diameter of the cyclone sediment mouth changes.When the sediment discharge port increases, the sediment volume increases, the mass fraction decreases, the fine grains increase, the overflow flow decreases, and the overflow becomes fine.On the contrary, when the sand tearing mouth decreases, the sediment settling mass fraction increases, the coarse grains in the overflow increase, and the overflow flow increases.

Desilting mouth can be change according to the judging of sand jet injection Angle, injection Angle generally at 40 ° ~ 70 °.If the sediment is discharged in the form of rope, it means that the sediment mouth is small and the sediment mass fraction increases.If the sediment is ejected in the shape of an umbrella, the sediment mouth is large, and the sediment mass fraction is greatly reduced.
