Calcite ultra-fine powder is widely used in medicine, toothpaste, feed, plastics, paper making, rubber, resin technology, ceramics, paints, coatings and building materials industries. Calcite’s application in paper making is an innovative technology in the paper industry. Ultra-fine calcite powder will be mixed some additives and other materials, and then the paper would be formed by blowing molding technology. This new paper can be widely used in office printing, housing decoration, material packaging and many other fields, and it has won a great market. Comparing with traditional papermaking technology, the electricity consumption of calcite papermaking is only 35% of that of traditional papermaking. In addition, calcite papermaking technology would not cause waste water discharge, and it could be seen as an energy-saving, environmental protection, efficient technology.
What are the processes needed for calcite to be used in paper making?
First of all, ore cleaning. The dirty ore needs to be washed with water and then be conveyed into the crushing system. The clean ore can enter the crushing system directly. Next is the breakage of calcite. After the calcite in the crushed stone funnel enters the jaw crusher through the funnel mouth, it is transported to the coarse crushed stone hopper by the hoist. And then these coarse crushed stones are transported to the hammer crusher by the vibrating disc. After being crushed, calcite would be just like sand.
The next step is the grinding process of calcite. At this stage, calcite grinding machine is needed. Well, it is known that there are many kinds of calcite grinding machines in the market now. And how can we choose the suitable calcite grinding machine? This depends on the customer’s requirements of powder fineness and capacity.

For ultra-fine calcite powder, superfine grinding machine is suggested here. This machine has been mentioned several times and it is also one of our representative products. Compared with other known grinding machines, this grinding mill has improved in the aspect of hourly capacity. Of course, the most typical characteristic of this equipment is its high output powder fineness.
As for the calcite powder within 400 mesh, Raymond mill can be a good choice. This machine is a frequently used machine in powder grinding field. What’s his bright spot? Its good price and low cost cannot be ignored.
