Quartz Processing | Mastering the Art of Stone to Powder

Author : Jordan Last Updated :

Quartz, a common silicate mineral, widely used in industry, is processed into granular quartz sand (silica sand) and finer quartz powder. With its finer particle size (exceeding 120 mesh) and higher purity, quartz powder is highly favored in the market.

In this article, we'll focus on quartz powder market trends, production processes, and efficient grinding machine types.

Quartz is a common silicate mineral

Booming quartz powder market

Quartz powder, highly favored by industries such as construction, glass, ceramics, electronics, and chemicals for its characteristics of high purity, heat resistance, and conductivity, has shown a steady growth trend in the market in recent years.

With the increasing awareness of environmental protection and the demand for high-quality materials, the demand for high-purity quartz powder is also rising.

In order to meet the market's demand for high-quality products, quartz powder manufacturers are continuously improving their crushing and grinding processes. It can be expected that the quartz powder market will continue to thrive in the future.

4 Steps for efficient processing of quartz powder

As the second most abundant mineral in the Earth's continental crust (after feldspar), quartz is typically extracted from underground using bulldozers through open-pit mining methods.

Post-extraction, quartz often undergoes industrial processes such as crushing, grinding, classification, and screening to obtain higher purity powdered products.

  • Quartz Crushing

    Jaw crushers are the ideal choice for primary crushing of quartz ore, effectively breaking down the high-hardness mineral. Subsequently, cone crushers (or impact crushers) further reduce the quartz to below 25 mm.

  • Quartz Grinding

    The finely crushed quartz particles are conveyed by bucket elevators to storage bins, then fed into quartz ball mills for grinding via electric-magnetic vibrating feeder, ultimately producing quartz powder (adjustable fineness ranging from 0.074 mm to 0.89 mm).

  • Quartz Classification

    Under the action of blowers, quartz powder is transported to the analyzer for fineness separation. During classification, overly coarse particles are rejected and returned to the ball mills for re-grinding.

  • Quartz Collection

    Powders meeting fineness requirements are collected by a cyclone collector and conveyed to the finished product bin. To maintain environmental cleanliness, the grinding process uses a pulse jet dust collector to gather excess dust, improving air quality and protecting worker health.

Safety at the forefront - putting people first

FTM Machinery's quartz grinding production line follows ESG principles, minimizing crystalline silica dust exposure risk with efficient processes, ensuring employee and community health while balancing production efficiency and economic benefits.

Which quartz grinding machine is suitable for your factory?

Quartz grinding machine is a key equipment in the grinding production line.

The distinct features of the following grinding machines can help you make a quick selection.

Equipment Ball Mill Raymond mill Vertical Roller Mill Ultralfine Mill
Price High Low High Low
Fineness Coarse powder Fine powder Fine powder Ultrafine powder
Yield High Normal Normal Low
Common Applications Ores, cement Non-flammable and non-explosive non-metallic materials Cement clinker, slag, coal powder Non-metallic minerals and chemical raw materials

In addition, you can also choose the appropriate grinding machine based on the particle size and properties of the ground product.

  • Based on product particle size: Ball Mill (20–200 mesh), Raymond Mill (80–325 mesh), Vertical Roller Mill (20–400 mesh), Ultrafine Mill (80–800 mesh).
  • Based on material properties: For materials with higher hardness, Ball Mill and Raymond Mill are recommended; for those with medium hardness, higher moisture, and viscosity, Vertical Roller Mill and Ultrafine Mill are suitable.

Next, let us take a detailed look at the advantages of these four quartz grinding machines together.
