SOLUTION

Heavy calcium carbonate, also known as heavy calcium, is mainly processed from natural carbonate minerals and is commonly used as an inorganic filler. It has high chemical purity and thermal stability, and relatively low hardness. It is widely used in industries such as construction, plastics, rubber, and paint, and has a wide range of applications. There are many equipment used in the processing of heavy calcium carbonate grinding mill, roughly divided into crushing and grinding equipment. Users can choose the appropriate grinding equipment according to the on-site construction situation to improve their work efficiency. Below, we will focus on the analysis of the grinding equipment used in the processing of heavy calcium carbonate.

1. Heavy calcium carbonate grinding mill equipment – crushing equipment

The crushing equipment used in the processing of heavy calcium carbonate grinding mill mainly includes jaw crushers, impact crushers, hammer crushers, and impact crushers.

2. Equipment for Heavy Calcium Carbonate Grinding Mill – Grinding Equipment

There are two types of grinding equipment used in the processing of heavy calcium carbonate grinding mill: Raymond mill and high-pressure suspended roller mill.

（1） Raymond mill

Raymond mill is very familiar to everyone. It is the most commonly used grinding equipment, mainly used for grinding heavy calcium carbonate after being crushed by a crusher. The fineness of the ground heavy calcium carbonate is very fine. This equipment has many advantages, such as small footprint, strong independence, easy operation, low failure rate, and large output.

（2）High pressure suspended roller mill

The high-pressure hanging roller milling machine, also known as the high-pressure milling machine, is a mature milling equipment optimized and designed based on the Raymond milling machine. It can also be applied to the milling operation of heavy calcium carbonate, and the milling effect is very good. Compared with other milling equipment, the output can be increased by about 20%. The finished product particle size range is very wide, and the dust prevention measures are also very good. There is almost no dust appearing on the construction site, and it has the advantages of stable operation, large output, zero noise, and high production efficiency.

3. Production process of heavy calcium carbonate

The production of heavy calcium carbonate usually adopts a dry process, which mainly includes the following steps:

Raw material preparation: Natural carbonate minerals (such as calcite, marble, limestone, etc.) are sorted, washed with water to remove impurities, dried, and sent to the raw material storage shed.

Crushing: The raw material is first crushed, usually using a jaw crusher or cone crusher, to crush it to the appropriate particle size.

Grinding: The crushed raw materials enter the grinding machine for grinding. Common equipment includes Raymond mill, ring roller mill, vertical mill, ultrafine vertical mill, etc. According to different product requirements, different grinding equipment can be selected.

Grading: The ground material is subjected to fineness grading using grading equipment such as analytical machines, cyclone separators, etc., to ensure that the product meets specific particle size requirements.

Collection and packaging: Powder that meets the requirements is collected through a dust removal system and packaged or stored.

4. Typical applications

Heavy calcium carbonate powder is widely used in multiple industries, including:

Plastic industry: As a filler, it improves the toughness, tensile strength, and impact strength of plastics.

Coatings industry: As a white filler and pigment, it improves the glossiness, dryness, and coverage of coatings.

Rubber industry: As an inorganic non-metallic filler, it improves the performance of rubber products.

Paper industry: used for producing ultrafine pulp to improve the smoothness and opacity of paper.

Construction industry: used for building materials such as interior and exterior wall coatings, putty powder, etc.
