How To Make Superfine Calcium Powder With Calcium Carbonate Grinding Mill?

Calcium carbonate powder has always had the title of “industrial grain”, and superfine heavy calcium powder is one of the main product forms, which has an irreplaceable role in the industry. Therefore, what is the Calcium carbonate grinding mill production process for superfine heavy calcium powder? What are the raw materials? What are the steps from raw material to finished product?

The Calcium carbonate powder production process of superfine heavy calcium powder mainly includes the following steps:

1. Calcium carbonate grinding mill production process – washing and beneficiation

After minerals rich in calcium carbonate such as calcite and marble are mined from the mine, the surface sediment is washed off with water, and the obviously black or gray stones are picked up;

2. Calcium carbonate grinding mill production process – initial crushing and fine crushing

Generally, the volume of raw ore is large, and it needs to go through two crushing processes: primary crushing and fine crushing. Generally, the particle size of the coarse powder calcium is controlled within 30mm, and the fine powder calcium is controlled within 15mm, which is beneficial to improve the grinding efficiency;

3. Calcium carbonate grinding mill production process – grinding and classification

The commonly used grinding equipment for coarse powder heavy calcium is Calcium carbonate Raymond mill, the fineness is generally 325 mesh, the high-end ultra-fine calcium powder uses an Calcium carbonate superfine vertical roller mill, and the ordinary ultra-fine calcium powder uses a Calcium carbonate ultrafine ring roller mill. The common mesh numbers are 600 mesh, 800 mesh, 1250 mesh, 1500 mesh, 2000 mesh, 2500 mesh, etc. The fineness can be adjusted by the fine powder separator.

4. Calcium carbonate grinding mill production process – finished product collection

After grinding, the calcium powder will be sent out through the classifier and collected by the pulse dust collector or cyclone collector, and then enter the finished product warehouse or directly through the discharge valve to the packaging machine for packaging.
