What is the silica sand process flow?

There are five main processes including Feeding, Crushing, Sand making, Screening and Washing for silica sand processing plant.

The raw material is conveyed to the primary crushing equipment through the feeder,it’s usually a jaw crusher.

The mined silica sand (quartz sand) ore is continuously fed into the coarse jaw crusher by the vibrating feeder for primary crushing, and then the particles after primary crushing are sent to the fine jaw crusher by the belt conveyor for re-crushing, and the crushed silica sand particles are sent to the vibrating screen for screening and grading.

After the screening process, the quartz sand particles that meet the feeding particle size requirements of the vertical shaft impact crusher enter the sand making machine for sand making process, and those that do not meet the requirements are returned to the crusher for re-crushing.

The qualified silica sand particles from the sand making machine are returned to the circular vibrating screen for re-screening, the materials that meet the requirements go to the next process, and the materials that do not meet the requirements are returned to the sand making machine for sand making and crushing again;

The produced silica sand is sent to the sand washing machine by the belt conveyor for cleaning, and the cleaned silica sand is sent to the finished product pile.
