Project Detail

Slippery Pipe, Chute, Screen Blockage Failure

When a dry mortar company produced mechanical sand, it first found that the fine sand and coarse sand fineness decreased at the same time, and then it was found that the fine sand chute and the slip tube were all blocked. When the Sand Screening Machine was inspected, it was found that most of the 2.5 mm screen and the 1.18 mm screen were covered with stone powder, and most of the Sand Screening Machine holes were blocked, resulting in failure to produce and stop working.

Rotary Sand Screening Machine Failure Reason

After analysis, it is found that since the dry powder mortar company is a newly built factory, the production personnel must not have a clear understanding of dry stone making with dry stone, and use wet stones with water content of up to 2%, resulting in the water content of the sand being 1% to 1.5%. After the stone powder is wetted by water, the viscosity is very large, and the stone powder cannot be extracted by the wind selection. The viscous stone powder sticks the sand together, so that the sand loses fluidity and blocks the sand chute and the slip tube; at the same time, the viscosity is very good. The large stone powder sticks to the Sand Screening Machine, and the more sticky, the more the sand sticks to the Sand Screening Machine, and the Sand Screening Machine is gradually blocked. In the process of more and more stone powder on the Sand Screening Machine, the Sand Screening Machine hole becomes smaller and smaller. The sand passing through the Sand Screening Machine is made finer and finer. After the slide pipe, the chute and the sieve mesh are mostly blocked, they cannot be produced.

Rotary Sand Screening Machine Troubleshooting Method

Use a special screen scraper to scrape off the stone powder and sand stuck on the Sand Screening Machine, clean the Sand Screening Machine; cut the wet sand in the pipe at the appropriate position of the chute and chute. All cleaned up, dredge the blocked pipes, and then dry the stone to make sand.
