Portable Aggregate Trommel Screening Maintenance

Posted: 2020-04-29

The portable aggregate trommel screen is a commonly used equipment in mineral processing, building materials, metallurgy, chemical industry, and other industries. Through the continuous rotation of the screen body, large pieces of waste stone can be thrown out, which greatly improves the output and reliability of the screening system and solves the clogging problem when screening wet materials. Sand trommel screening maintenance should be done normally to avoid affecting the production and serious damage to the trommel screen.

Moreover, the large bearings in the equipment should be replaced with lubricating oil every two months, 2/3 is suitable, not too much, otherwise, it will cause bearing heat.
