The particle size of the heavy calcium carbonate powder is more uniform by using the air classifier
It is well known in the industry that there are different processes for the processing of heavy calcium carbonate powder in dry and wet methods. Dry processing is more conducive to achieving industrial scale and a certain degree of product refinement. Therefore, many companies have chosen to use air classifiers to obtain more refined heavy calcium carbonate powder.
The heavy calcium carbonate powder with uneven thickness moves to the classification area at high speed from the inlet of the lower end of the air flow classifier with the updraft under the suction force of the fan. Under the action of the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. The fine particles that meet the particle size requirements enter the cyclone separator or dust collector through the gap of the grading wheel blades, and the coarse particles entrain the part of the fine particles after hitting the wall. The speed disappears. The washing action separates the coarse and fine particles, the fine particles rise to the classification zone for secondary classification, and the coarse particles fall to the discharge port.
The particle size of the heavy calcium carbonate powder processed by the air classifier is more concentrated, and the heavy calcium carbonate powder processed by the air classifier is more widely used:
1. Heavy calcium powder for artificial marble industry: 325 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5%, pure and no impurities. Calcium carbonate has been widely used in the production of artificial marble.
2. Heavy calcium powder for floor tile industry: 400 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5%, pure and no impurities. Calcium carbonate can be used in the floor tile industry to increase the whiteness and tensile strength of the product, improve the toughness of the product, and reduce the production cost.
3. Heavy calcium powder for paper industry: 325 mesh, whiteness requirement: 95%, calcium carbonate content: 98%. The important role of calcium carbonate in the paper industry: it can ensure the strength and whiteness of the paper, and the cost is low.
4. Heavy calcium powder for construction industry (dry mortar, concrete): 325 mesh, whiteness requirement: 95%, calcium carbonate content: 98%. Calcium carbonate plays an important role in concrete in the construction industry, not only can reduce production costs, but also increase the toughness and strength of the product.
5. Heavy calcium powder for fire-proof ceiling industry: 600 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5%. Calcium carbonate is used in the production process of fireproof ceilings, which can improve the whiteness and brightness of the product, and the fireproof performance will also increase.
