What type of crusher is required for producing quartz sand
Quartzite's primary chemical composition is quartz—SiO₂, a metamorphic rock predominantly composed of quartz (over 85% quartz content). It forms through the metamorphism of quartz sandstone and siliceous rocks. Typically, it results from regional metamorphism and recrystallisation of quartz sandstone or other siliceous rocks.
As a natural stone material, quartzite is widely prevalent in nature due to its high hardness (exceeding 7 on the Mohs scale) and excellent corrosion resistance. It is not only frequently utilised in interior decoration but also serves as the primary raw material for manufactured sand.
What type of crushing equipment is required for producing sand from quartzite? Considering its high hardness and current market production practices, the following crushers are recommended:
A. Primary Crushing Equipment: Jaw Crusher Recommended
The jaw crusher comprises a crushing chamber formed by two jaw plates—a moving jaw and a stationary jaw—which mimic the motion of an animal's jaws to perform material crushing.
With its large feed opening, it can handle the crushing of hard, medium-hard, and soft ores such as large river pebbles, marble, calcite, limestone, basalt, quartzite, and various other materials. Quartzite is a hard material demanding high equipment standards. OCP Heavy Industry selects raw materials of superior quality, fully meeting customer requirements.
B. Secondary Crushing with Cone Crushers
During operation, the motor drives the eccentric sleeve via transmission mechanisms. The moving cone oscillates under the eccentric shaft sleeve's force, forming the crushing chamber where material undergoes repeated compression and impact between both cones.
Cone crushers are particularly suited to processing high-hardness rocks, making them ideal as secondary fine crushing equipment in quartz sand production lines.
C. Sand-making machines recommended for fine crushing and shaping
Sand-making machines, also known as vertical shaft impact crushers, are suitable for crushing soft, medium-hard, and extremely hard mineral materials with hardness not exceeding 320 Pa.
The OCP Heavy Industry Vertical Impact Sand Maker is a high-performance sand-making device independently developed by our company, representing advanced technology. Its performance plays an irreplaceable role among various fine crushing equipment for ores. Vertical impact crushers (sand makers) operate in two modes: ‘stone-on-stone’ and ‘stone-on-iron’. The ‘stone-on-stone’ type processes highly abrasive materials, while the ‘stone-on-iron’ type handles less abrasive materials. The ‘stone-on-iron’ type achieves a sand yield 10-20% higher than the ‘stone-on-stone’ type.
When selecting equipment, one should choose suitable crushing machinery based on actual operational requirements and site conditions. OCP Heavy Industry integrates diverse brands, models, and specifications of crushing and grinding equipment, alongside manufacturers from across the region. We welcome enquiries!
