Heavy calcium carbonate, referred to as heavy calcium, is a white powder processed from high-quality limestone or calcite. It is commonly used as a filler and is also widely used in artificial floor tiles, rubber, plastics, paper, paint, paint, ink, cable,Construction supplies, food, medicine, textile, feed, toothpaste and other industries.It can be used as a filler to increase the volume of the product and reduce the production cost.
Calcium carbonate is widely used, but it must be processed by a mill to different fineness for further use. The dry process of heavy calcium carbonate is the first choice: calcite, limestone, chalk, shells, etc., which are shipped from the quarry.The gangue is removed; then the stone is coarsely crushed by a crusher, and then crushed with a calcium carbonate mill to obtain fine limestone powder. Finally, the mill is classified by a classifier, and the powder meeting the particle size requirement is packaged as a product.Otherwise return to the calcium carbonate pulverizer and grind again.The whole set of calcium carbonate mill is mainly composed of mill main machine, powder separator, fan, smashing, bucket elevator, electromagnetic vibrating feeder, storage bin, bag filter, pipe device, cyclone collector,Electric control cabinet, motor and other components.The whole machine of calcium carbonate mill is vertical structure, with small floor space and strong set, and the main drive unit adopts a closed gear box for stable transmission.The important parts of the mill are made of high-quality steel, so the machine is durable and reliable.The electrical system of the milling machine adopts centralized control, the selection is advanced and reasonable, and the degree of automation is high. The vibration feeder is small in size, light in weight, easy to adjust and saves electricity.
Calcium carbonate is commonly used in the construction and paper industries and can be used as an additive in the food industry.Calcium carbonate within 200 mesh can be used in various feed additives with a calcium content of more than 55.6 and no harmful ingredients.250 mesh to 300 mesh calcium carbonate is used as raw material and interior and exterior wall paint for plastics, rubber, paint, and waterproof materials. The whiteness is above 85 degrees.350 mesh to 400 mesh calcium carbonate is used in the manufacture of gussets, water pipes, chemical, whiteness above 93 degrees.400 mesh to 600 mesh calcium carbonate can be used in toothpaste paste, soap, whiteness above 94 degrees.800 mesh calcium carbonate is used in rubber, plastic, cable, pvc, whiteness is above 94 degrees.1250 mesh calcium carbonate can be used in pvc, PE, paint, coating grade products, paper coating, paper coating, whiteness above 95 degrees, high purity, high whiteness, non-toxic, odorless, low oil quality,Low hardness and other characteristics.
The calcium carbonate superfine mill is widely used as an environmentally friendly material in various fields. It can effectively reduce the use of expensive materials, especially in plastic products, because it is filled with calcium carbonate. It saves the use of plastic materials and reduces the cost of the products. For example, after the surface modification of calcium carbonate by the surface of the active agent, more than 50% can be added to the plastic film, which effectively reduces the amount of plastic used. The plastic film with high filling powder is not only low in cost, but also decomposed after being discarded outside in the sun for a few days after use, and does not cause environmental pollution. At present, the output of plastic products in China is about 70 million tons. If the filling amount of calcium carbonate in plastic products is increased by 1% evenly, it can save about 200,000 tons of plastics. According to the calculation of 3 tons of crude oil per ton of plastic, it can save 600,000. Tons of oil.
