Calcium carbonate ultra fine powder machine plant

Calcium carbonate is a chemical compound with the formula CaCO₃. It is a common substance found in rocks, such as calcite, aragonite, vaterite, limestone, chalk, marble, travertine and so on, and it is about in all parts of the world. Moreover, Calcite, aragonite and vaterite are pure calcium carbonate minerals, but limestone, chalk, marble and travertine are industrially important source minerals. The main use of calcium carbonate is in the construction industry, either as a building material or limestone aggregate for road building or as an ingredient of cement or as the starting material for the preparation of builder's lime by burning in a kiln.
Besides, calcium carbonate is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural lime, and is usually the principal cause of hard water. It is commonly used medicinally as a calcium supplement or as an antacid, but excessive consumption can be hazardous.
The vast majority of calcium carbonate used in industry is extracted by mining or quarrying. And how to get the pure calcium carbonate powder, the calcium carbonate ultra fine powder machine will be your best choice.
Calcium carbonate ultra fine powder machine plant usually consists of ultra fine powder machine main unit, classifier, powder collector, dust cleaner, induced draft fan, muffler, sound-proof room, crusher machines, bucket elevator, storage hopper, and vibrating feeder.
>>Introduce of Calcium Carbonate ultra fine powder machine:
Calcium carbonate ultra fine powder machine can be used in pulverizing non-inflammable, non-explosive and brittle materials with Moh’s hardness under nine, such as calcite, kaolin, limestone, calcite, barites, carbon black, mica, quartz etc. With the development of high-tech industry, fine and superfine powder is widely applied in various fields, Clirik Calcium Carbonate ultra fine powder machine become more and more requires by various industries.
>>Working principle of Calcium Carbonate ultra fine powder machine:
Clirik Calcium Carbonate ultra fine powder machine working principle is when the Calcium Carbonate ultra fine powder machine is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.
After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, edge of then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe. The high-pressure air blower constantly inhales air within the ultra fine powder machine and, in turn, the air flow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall an exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner, and clings to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end.
 

>>Features of Calcium Carbonate ultra fine powder machine:
***High efficiency
Under the same finished final size and the same motor power, the capacity of micro powder ultra fine powder machine is twice as much as jet mill, mixing grinder and ball mill.
***Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
***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.
***High fineness and flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≤5um.
***Environment-friendly
The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
