Silica powder production line

Process Description

• 01

  Sand making and screening

  Ore with a particle size of less than 400mm is fed by a loader into a vibrating screen, a feeder, and then into a sand grinder. The material produced by the sand grinder is separated by a separation screen to separate 40-mesh and 120-mesh finished products, and the coarse sand larger than 6-mesh is returned to the sand grinder for re-grinding.

• 02

  Magnetic separation and grinding

  After screening, the 5mm finer material passes through a bucket elevator and a buffer silo, and then enters a magnetic separator to remove magnetic impurities. The impurity-removed material enters a ball mill through a metering belt scale and is ground into fine powder.

• 03

  Finished product classification

  The ground material is classified into coarse and fine particle products by a classification system composed of airflow classifiers, cyclone collectors, pulse bag dust collectors, high-pressure induced draft fans and other equipment. The coarse particle products are returned to the ball mill through a belt conveyor for re-grinding, and the fine particles are collected as finished products.

• 04

  Dust Removal

  The entire system is a closed-loop system operating under negative pressure and equipped with a central dust collector. The gas discharged by the induced draft fan is clean gas that meets environmental protection requirements, and there is no dust spillage during the entire production process.
