Summary:Improve the cleanness of lubrication system in crushing and grinding equipment in beneficiation plant can ensure the smooth of lubricating oil circuit and the normal lubrication of the friction pairs

Recently, a certain number of customers both at home and abroad have inquired about the calcite powder making machinery, which is specially for producing calcite powder. As a professional manufacturer of mining equipment, SBM can design and install different processing lines and mining machines for our honored customers. And then let us have a look at more details of calcite powder production machine, also called calcite dust making machinery in some countries.

Analysis of Calcite Powder Market

Micronised calcite powder is basically used as a filler in innumerable industries. The fine powdered form of calcite has variety of uses depending upon the whiteness, purity in terms of CaCo3 content and plastic micronised size which range from 20 microns to 5 microns. Micronised Calcite powder is mainly used as extenders in all type of paint industries and filler for polymers, rigid PVC pipes, PVC profiles & flooring, HDPE pipes filled PP, colour master batches, ink, paper coating, pharmaceutical and rubber industries. Today, as a major construction material, the role of calcite powder can not be ignored. Therefore, the market prospect of calcite powder is very inspiring.

Production Flowchart of Calcite Powder

The production flowchart of calcite powder can be divided into five stages, including the conveying, crushing, partial drying, milling and calcination. Upon removal, trucks transport calcite stones to the processing plant. A vibrating feeder moves the raw calcite stones into the processing plant. The vibrating feeder consists of a conveyor belt that shakes to evenly distribute the calcite rock onto the conveyor surface. The conveyor feeds the rock into a jaw crusher, which can pulverize the rock into pieces measuring 2 inches or less. After crushing, small calcite rocks enter a drying receptacle. The receptacle spins and heats the rocks evenly. The rock dryer transforms the calcite into what is called a “hemi-hydrate.” And then, grinding machine deal with calcite particles, and plaster of Paris is composed of this hemi-hydrate crushed material. The final mining stage is calcination, which heats the calcite to high temperatures. This transforms the hemi-hydrate into an anhydrite. The anhydrite form of calcite provides further strength in plaster usage. Usually, the manufacturer adds water to reshape the calcite into a desired form.

Calcite Powder Production Machine-LM vertical mill

LM vertical mill is used as the calcite powder making machinery. SBM’s LM series vertical mill is the newest grinding machine, which integrates the advanced international technology and years of rich experience. It is the ideal equipment that integrates crushing, drying, grinding and grading conveyor all together. So, calcite powder producers need not buy another drier to combine with the calcite mill, which can significantly reduce the mining investment.
