Silica Sand Processing Solutions

Silica sand is processed by crushing, screening and washing of natural quartz ore. It is mainly used in glass industry, foundry industry, condiment field, metal silicon production and electronic industry.

With the rapid development of industrial technology, the demand for silica sand production is increasing day by day, which brings about higher requirements for silica sand production technology.

Silica sand can be divided into coarse silica sand and high purity silica sand. Now, introduce 2 kinds of silica sand processing solutions:

coarse silica sand

1.Coarse  Silica Sand Processing

Ore sorting → Rinse → Primary crushing → Secondary crushing → Sand making → Grading & dewatering → Scrubbing → Secondary iron removal → Dewatering + slurry adjustment + flotation (iron removal) → Dewatering + slurry adjustment + flotation (mica removal) → Dewatering + slurry adjustment + flotation (feldspar removal) → Clean → Dewatering

2.High Purity Silica Sand Processing

(The following operations are performed on the basis of coarse silica sand)

Acid leaching → Deionized washing → Dry → Packing

Basic Flow of Coarse Silica Sand Production Line

silica process

1. Silica sand is fed into the feeder by forklift truck. Belt conveyor is placed at the tail of the feeder. Silica sand from the tail is conveyed by belt conveyor to jaw crusher for primary crushing.

2. The coarse material produced by primary crushing is transported by conveyor to fine crusher for further crushing. The fine crushed material enters the vibrating screen to screen out two kinds of materials, the quartz stones that meet the feed size of the sand making machine fed into sand machiens, The return materials that do not meet the feed requirements return for fine crushing.

3.Part of the quartzite that fed into sand machine becomes silica sand. After washing by sand washer (optional) and recycling by fines recovery unit, finished quartz sand achieved. The other part of the quartzite return for crushing again.
