How to choose calcite grinding equipment?

Calcite is a common natural calcium carbonate widely distributed. It is heavy calcium carbonate and can be used for grinding powder. The ground calcite powder can be used in the cement manufacturing industry and is the main raw material for making cement. In addition, calcite powder can also be used in chemical, rubber, plastics, medicine, coatings, papermaking, glass, ceramics and other industries.

The selection of calcite grinding equipment mainly considers the following factors:

Material properties of calcite

Calcite has a hardness of 3 and a Mohs hardness of 3, making it a medium-hard material. The specific gravity of calcite is 2.71g/cm³ and it has a large density. The block size of calcite is generally 10-30mm, and it needs to be crushed before grinding.

Types of grinding mill

Common types of grinding mills on the market include Raymond mill, ultra-fine grinding mill, high-pressure suspension roller mill, airflow mill, etc. Among them, Raymond mill is one of the most widely used grinding machines at present, suitable for grinding 80-325 mesh calcite; ultra-fine grinding is suitable for grinding 325-2500 mesh calcite; high-pressure suspension roller mill is suitable for Grinding and processing of calcite below 1000 mesh; airflow mill is suitable for grinding and grinding of calcite of 5-40 microns.

Production requirements

Production requirements mainly include production capacity requirements, finished product granularity requirements, investment budget, etc. Capacity requirements are an important basis for selecting a grinding mill model. The particle size requirements of the finished product determine the type and model of the grinding mill. Investment budget is also an important factor to consider when choosing a grinding mill.

Other factors

In addition to the above factors, factors such as the equipment's floor space, energy consumption, and environmental performance must also be considered when selecting calcite grinding equipment.

Suggestions for selecting calcite grinding equipment

For calcite grinding powder processing with low production capacity requirements and low finished product particle size requirements, you can choose Raymond mill.

For calcite grinding powder processing that requires higher production capacity and higher particle size requirements for finished products, you can choose ultra-fine grinding or high-pressure suspension roller mill.

For calcite grinding processing that requires ultra-fine powder, you can choose an airflow mill.

When selecting a grinding mill, factors such as production needs and investment budget must be comprehensively considered to select the equipment with the highest cost performance.

The following are some common calcite grinding equipment:

Raymond mill

Raymond mill is a relatively traditional grinding mill with the advantages of simple structure, convenient operation and low maintenance cost. Raymond mill is suitable for grinding and processing of 80-325 mesh calcite.

Ultra fine grinding

Ultra-fine grinding mill is a new type of grinding machine, which has the advantages of fine particle size of finished products, low energy consumption, and good environmental performance. Ultra-fine grinding is suitable for grinding 325-2500 mesh calcite.

High pressure suspension roller mill

The high-pressure suspension roller mill is an efficient grinding mill with the advantages of high output, uniform particle size of finished products, and low energy consumption. High-pressure suspension roller mill is suitable for grinding calcite powder below 1000 mesh.

Jet mill

Jet mill is an ultra-fine grinding mill with the advantages of fine particle size of finished products, low energy consumption, and good environmental performance. The jet mill is suitable for grinding 5-40 micron calcite powder.
