Calcium carbonate powder generally includes heavy calcium powder and light calcium powder. Heavy calcium carbonate is referred to as heavy calcium. It is processed into white powder by using high quality calcite as raw material. Its main component is CaCO3, and the heavy calcium powder has high whiteness. Good purity, soft hue and stable chemical composition. Therefore, heavy calcium is a good filler commonly used in industry. Light calcium powder is obtained by calcining raw materials such as limestone to produce lime and carbon dioxide by dehydration, drying and pulverization.

Calcium carbonate grinding mill system

Calcium carbonate mill is a new type of fine powder and ultra-fine powder processing equipment. It is suitable for processing non-flammable and explosive brittle materials with Mohs hardness less than 6 grade. It is also the main equipment used in the current calcium carbonate grinding process. one. The system consists of four parts: feeding, grinding separation, finished product collection and electrical instrumentation. The feeding device is composed of a buried scraper conveyor, a storage bin and a screw conveyor; the grinding and separating device is composed of a milling machine and an analysis machine, and the two are assembled into one body, which is the core equipment of the whole system; The cyclone dust collector, dust collector and high-pressure induced draft fan are mainly used to complete the collection of finished materials and exhaust emissions; the electrical instrument device is the control part of the whole system, which can realize the switch and chain of each group of electrical equipment, and finally lead to it through PLC. The control room is remotely controlled.

How does the calcium carbonate grinding mill work?


When working, the calcium carbonate material coming out of the drying furnace is sent to the storage bin through the buried scraper conveyor, and then the material is intermittently fed into the feeding pipe of the calcium carbonate grinding mill manufacturer through the screw conveyor installed at the bottom of the warehouse, and the material is uniform. Falling onto the upper bulk disc of the grinding disc, the main motor drives the main shaft and the grinding disc to rotate through the reducer, and the roller pin at the edge of the grinding disc drives dozens of ring rollers to roll and rotate in the grinding ring raceway. The material is scattered to the periphery under the action of centrifugal force, and falls into the raceway of the grinding ring by the ring roll, rolling, grinding and grinding, and the material is crushed by the first layer and falls into the second layer and the third layer, and is centrifuged by high pressure. The suction of the fan draws outside air into the machine and brings the material pulverized through the third layer into the classifier. The rotating impeller in the classifier re-grinds the coarse material, and the fine powder enters the cyclone collector with the airflow and is discharged from the lower discharge valve, and the airflow with a small amount of fine dust passes through the pulse dust collector. After purification, it is discharged through a fan and a muffler.

Calcium carbonate grinding mill performance advantages

  1. 1. The calcium carbonate mill changes the traditional part of the analyzer from the cavity to the outside of the cavity, so that the rotation inside the transmission cavity is isolated, and the center has no swing, thereby enhancing the stability of the work.
  2. 2. Equipped with a high-density impeller that can improve the accuracy of calcium carbonate powder, the airflow resistance is reduced under the condition of constant rotation speed, and the fineness of the ground calcium carbonate is higher under the same power.
  3. 3. The structure of the grinding roller has been updated so that the grinding roller and the grinding roller shaft can complement each other, which improves the durability of the grinding roller and reduces the wear of the wear parts.
  4. 4. Calcium carbonate grinding machine is made of high-quality materials and has fine craftsmanship, which ensures the high efficiency and good wear resistance of the whole set of Raymond mill equipment.
  5. 5. The wear life of the calcium carbonate mill has a long service life, and the grinding roller and the grinding ring are forged by special materials, so that the utilization degree is greatly improved. In the case of the same material and finished product fineness, the service life of the wear parts of the impact crusher and the turbo crusher is 2-5 times longer, generally more than one year, and the service life can reach 2-5 when processing calcium carbonate. year.
