Device Introduction:

This product is a new specialized production line for quartz plate sand, developed by our company through years of practice. Compared with ordinary sand making machines and mills, it can directly feed materials of 300mm and produce qualified products ranging from 4 mesh to 120 mesh in a single process, significantly reducing the process flow. It minimizes equipment wear during the crushing process, thereby ensuring the purity of the materials. The optimized design allows for the production of products with various particle size segments according to customer requirements, expanding the application range of the products.

Highlight advantages:

1. High sand production rate: With a reasonable length-to-diameter ratio and a scientifically designed discharge structure, over-grinding of materials is significantly reduced. The sand production rate for 4-120 mesh can reach over 90%.

2. High purity and pollution-free: The inner wall is lined with materials such as silica and corundum, and the material is ground using a self-grinding method without media, ensuring no iron contamination during the crushing process, thereby maintaining the purity of the material.

3. The product has a rounded particle shape and uniform particle size, which is more conducive to the subsequent processes of panel manufacturers. The rotation speed of the cylinder has been strictly calculated, with two forms available: fixed speed and variable frequency speed regulation, thereby achieving the **grinding effect** you require.

4. The entire set of equipment features a simple and reasonable structure, easy operation, low failure rate, and convenient maintenance.

Working Principle:

The raw ore, stored in a silo and measuring less than 450mm, is uniformly fed into a high-purity sand-making machine via a feeder. The high-purity sand-making machine is equipped with quartz or ceramic liners inside its chamber. As the drum rotates, centrifugal force lifts the raw material to a certain height before it falls, causing impact and grinding effects on the material. The powdered material that meets the required specifications is discharged through a discharge grate, completing the grinding process. The material output from the sand-making machine is then separated by a primary screening sieve. Coarse particles larger than 4 mesh are returned to the mill for further crushing, while particles smaller than 4 mesh undergo iron removal via a magnetic separator before passing through a secondary screening sieve. This sieve separates the material into products of 4-6, 6-8, 8-16, 16-26, 26-40, 40-70, 70-120, and -120 mesh sizes. The entire system is equipped with a high-efficiency pulse baghouse dust collector, ensuring that the production process is environmentally friendly, safe, and pollution-free.
