Powder Processing Plant Resumed

There is a shortage of heavy calcium powder in the paper industry. Let's resume the powder processing plant. "Heavy calcium powder is still available. Where is it?" Many paper industry bosses keep calling and asking, looking for a powder processing company to require heavy calcium powder, because the factory resumes work every day requires a lot of heavy calcium powder. However, due to the epidemic situation, the supply of powder raw materials by upstream companies was not available, which caused these companies to resume production and work normally.

Importance of the paper industry

Let's talk about the heavy calcium powder to be used in the paper industry first. How important is it? Heavy calcium carbonate, referred to as heavy calcium, is ground from natural carbonate minerals, such as calcite, marble, and limestone. It is a commonly used powdery inorganic filler. It is used in the paper, plastic, rubber, paint, and pharmaceutical industries. High application value.

The shape of heavy calcium particles is irregular, and it is a polydisperse powder. The average particle size is generally 5-10 μm. The application fields of powders with different fineness are not the same. For example, powders within 200 mesh can be used for various feed additives with a calcium content of 55.6 or more without harmful ingredients; 350 mesh-400 mesh powder can be used to manufacture gussets and downpipes. , Chemical industry, whiteness above 93 degrees. There are 325 mesh, 400 mesh coarse powder, 800 mesh fine powder, 1250 mesh, 2000 mesh superfine powder, etc., which are mainly used in the market.

1. Papermaking (400-1000 mesh): Papermaking fillers, which ensure the opacity, strength, whiteness, smoothness, and printability of paper, replace a large number of pulp fibers and reduce costs.
2. Plastic (800-2500 mesh): Improve color, hardness and thermal conductivity. Control the rheological properties of PVC plastisol and improve the anti-caking ability of polyethylene.
3. Coating (800-3000 mesh): skeleton effect, enhance the sedimentation and permeability of the primer to the surface of the base layer. In thick paint, thicken and thicken the coating.
4. Rubber (400-2000 mesh): provides permeability, chemical resistance and shielding.

Therefore, not only the boss of the paper industry crying, but also the coatings, rubber, and plastic processing industries. Refer to the price list of different fineness of calcium carbonate powder before the price increase:

1. 800 mesh +: 200-8000 yuan / ton
2. 400-600 mesh: 60-520 yuan / ton
3. 25-400 mesh: 10-300 yuan / ton
4. 250-300 mesh: 90-180 yuan / ton
5. ＜ 200 mesh: 90-200 yuan / ton

China's demand for heavy calcium is increasing every year, from 18.48 million tons in 2015 to 24.54 million tons in 2019. With reference to the growth of heavy calcium demand in recent years, it is estimated that it will reach 26.06 million tons in 2020. broad. If you have ore resources, you might as well seize the opportunity and give it a try.

Common heavy calcium grinding equipment

For heavy calcium grinding equipment, commonly used Raymond mill (80-425 mesh), ultra-fine vertical mill (325-3000 mesh), ultra-fine powder mill (325-2500 mesh), etc. All are suitable for processing heavy calcium powder. Customers who are interested in investing, according to the fineness of the finished product they want, choose the appropriate mill. For the mill price, please consult our online customer service.
