How to choose Calcite powder grinding mill?

Calcite powder mill is also called calcite grinding machine, or calcium carbonate grinding mill. It grinds calcite minerals into various fine powders that can meet the requirements of industrial applications.

What is calcite rock?

Calcite, one kind of calcium carbonate material, is existed in nature. It has low production cost and high industrial processing value. The finished fine powder is widely used in glass, ceramics, construction, chemical industry, light industry and other fields.

The renewed importance of calcite powder makes more and more people come into this calcite powder industry. How to configure the production line equipment of calcareous powder with a daily production capacity of 500 tons? How much is the investment? Baichy machinery, as an experienced manufacturer of grinding equipment in the industry, will solve doubts and give solution for everyone.

What is the calcite grinding process?

Calcite ore, generally the finished fine powder is 40-800 mesh. And raw calcalite material lump is large, it can not directly into the material grinding, so first through the jaw crusher simple crushing, at the same time need to be equipped with the corresponding electromagnetic feeder, bucket elevator, powder separator, dust removal equipment. Process is including:

1. Crushing: raw calcite ore goes into the jaw crusher preliminary crushing, in order to reach the grinding size.
2. Grinding: The broken calcalite is fed into the silo from bottom to top by the bucket elevator, and then evenly fed into the vertical roller grinding mill by the electromagnetic feeder for grinding and processing, and the output particle size is adjusted according to needs.

3. Powder selection : The powdered calcite powder needs to be further graded by the powder classifier. It could obtain the finished product calcite powder with higher purity and more in line with the standards
4. Powder collection: The powder after classified enters to cyclone collector to send to finished product silo and then packed by a powder tanker or an automatic baler.

How to choose calcite powder grinding mill plant

Finished products: The particle size and production capacity of the finished products. It will decide the machine model and types.

Machine material: High-quality steel makes the machine durable and reliable.
Control system: Centralized control with advanced shape and high atomicity make the grinding mill plant more efficiency

What machine to suitable to grind calcite powder?

In powder grinding production, different raw materials or different fineness requirements need to choose different types of mills. So for the calcite powder production, which type of mill is suitable to choose?

1.Raymond mill

The working principle of Raymond mill is that the blades installed on the base shovel limestone or marble into the vertical gap between the grinding rollers and the grinding ring. The material is squeezed into powder. The final powder size is 80-425mesh. The classifier is on top of raymond mill. The ground powder could be classified directly in grinding chamber. The total working place is small.

2.HGM ultrafine grinding mill

HGM ultrafine mill has the same working principle as Raymond mill. Two improvements increase its grinding efficiency and powder production finess. One is that the high-pressure spring device improves the grinding pressure of the grinding rollers. It uses more rollers and horizontal type roller allocation. The other is that the improved classifier can precisely adjust the fineness of the finished products.

3.Ball mill

The calcium carbonate ball mill works by rotating a cylinder with grinding media. The grinding balls fall back into the cylinder and on to the material to be ground. The ball mill can be operated either wet or dry. The particle size of the finished product can be adjusted by controlling the grinding time, rotating speed, size and composition of grinding media, additives, etc. In ball mill plant, the classifier needs the special air classifier. Ball mill are popular in large calcium carbonate grinding plants due to high throughput.

What is the investment of a calcite grinding production line with a daily production capacity of 500 tons? Here to remind users, it is important is to choose the right equipment manufacturers, choose more appropriate equipment, design more scientific production line.

People Also Frequently Asked for-FAQ

What is the difference between calcite powder and calcium carbonate?

Calcite is a mineral with a distinct crystallographic structure. Calcium carbonate refers only to chemical composition, CaCO3, and says nothing about structure. There are multiple minerals with the composition CaCO3 but each with different structures : calcite, vaterite, aragonite .

What is calcite powder also known as?

Calcite is also known as chalk powder or natural calcium carbonate. It is in bright white color and it has nodular particle size with crytaline structure. Used in economic quality cement primer, wood primer, Cement paint, metal primer, distemper, emulsion paint, texture coating etc.

How does a Raymond roller mill work?

As the unit turns, centrifugal force drives the rolls against the grinding ring. Feed material enters the mill from the top of the grinding zone and moves down to the mill bottom by gravity. It is then lifted up by plows from the mill bottom to the nip area of the grinding rolls and ring where the grinding occurs.

What is the difference between a ball mill and a Raymond mill?

Raymond mills are used in many industries including mineral processing, cement plants, power generation and more. Ball Mills are slow speed horizontal mills with a rugged design and ease of maintenance coupled with excellent performance.
