About Calcium Carbonate
White solid, tasteless, odorless. There are two forms, amorphous and crystalline. The crystal type can be divided into rhombic crystal system and hexagonal crystal system, which are columnar or diamond shaped. The relative density is 2.71. 825 ~ 896.6℃ decomposition, at about 825℃ decomposition into calcium oxide and carbon dioxide. The melting point is 1339℃, and the melting point at 10.7MPa is 1289℃. Insoluble in water and alcohol. It reacts with dilute acid and releases carbon dioxide at the same time, which is an exothermic reaction. Also soluble in ammonium chloride solution. Almost insoluble in water.

In modern industry, calcium carbonate is the main raw material for the manufacture of cement, lime, calcium carbide, is an indispensable flux limestone in the metallurgical industry, high-quality limestone after ultrafine grinding, is widely used in the manufacture of paper, rubber, paint, coatings, medicine, cosmetics, feed, sealing, bonding, polishing and other products.
Calcium Carbonate Powder Processing Technology
The whole structure of the calcium carbonate mill is composed of the main machine, the analytical machine (powder separator), the pipeline device, the blower, the finished cyclone separator, the jaw crusher, the elevator, the electromagnetic vibration feeder, the electric control motor, etc. The main machine of calcium carbonate mill is composed of frame, air inlet volute, shovel knife, grinding roller, grinding ring, cover shell and motor.

Working Principle of Calcium Carbonate Mill
When the main machine of the calcium carbonate mill is working, the mill roller is tightly rolled on the grinding ring under the action of centrifugal force, and the material is sent to the middle of the mill roller and the grinding ring by the shovel knife. The material is broken into powder under the action of grinding pressure, and then the powder is blown up under the action of the fan and passes through the analysis machine. The material that meets the fineness requirement passes through the analysis machine, and the material that fails to meet the requirement returns to the grinding chamber to continue grinding. The material is separated and collected through the cyclone separator of the analyzer. Exhaust air with industrial filter cloth isolation exhaust air into powder.
Calcium Carbonate Grinding Production Line Equipment Recommendation
The first thing to use for processing calcium carbonate powder is the crusher (jaw crusher, cone crusher, impact crusher, etc.), and the most important thing in the whole equipment is the grinding machine. The grinding mill mainly used for processing calcium carbonate are ultrafine grinding machines, ring roller grinding machines and Raymond grinding machines.
Calcium carbonate powder processing is divided into fine powder processing (50~325 mesh) and ultra-fine powder processing (325~3000 mesh).

If you need to process fine powder, we recommend using a YGM Raymond mill

YGM Raymond mill

Capacity:0.2~50 t/h
Feeding size:35 mm
Powder fineness:50~325 mesh

Mill advantages
1. Smooth vibration reduction design.
2. Convenient blade adjustment design.
3. This machine is suitable for a variety of materials with Mohs hardness less than 9.3.
4. The grinding device adopts superimposed multistage sealing, with good sealing performance.

If you need to process ultrafine powder, we recommend the HGM type ultrafine grinding mill and CLUM type ultrafine vertical grinding mill

HGM Ultrafine grinding mill

Capacity:1~40 t/h
Feeding size:≤20 mm
Powder fineness:325~3000 mesh

Mill advantages
1.High Efficiency.
Under the same finished final size and the same motor power, the capacity of the machine is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.

2.Long lifecycle of spare parts.
The ring and roller are forged by special material with high utilization,the lifetime can reach 2 ~ 5 years for grinding calcite carbonate.

3.High safety and reliability.
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.

4.High fineness, flexible adjustment.
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 mesh, and the product fineness can reach D97≤5μm.

5.Environment-friendly.

ClUM Ultrafine vertical grinding mill

Capacity:3~20 t/h
Feeding size：＜10 mm
Powder fineness:200~3000 mesh

Mil advantages
1.High grinding efficiency: save 20~30% power consumption compared with the ball mill. With the increasing of moisture content, it can save more and more electricity.

2. Strong drying capacity: dry and grind raw materials with moisture content as much as 15%.

3. Mutifunction: crushing, drying, grinding, separating and conveying.

4. Low noises and little dust: no direct contact between the grinding rollers and grinding disc, so metallic impact is avoided and its noises is 20~25 decibels lower. Totally closed negative pressure operation has employed by this vertical grinding mill, so there is no dust during the operation.

5. Low wear rate and little metallic pollution: its metal wear is only 5~10g/t.
