HGM&YGM grinding mill for carbonate of lime

Carbonate of lime 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 carbonate of lime minerals, but limestone, chalk, marble and travertine are industrially important source minerals. The main use of carbonate of lime 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, carbonate of lime is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells. Carbonate of lime 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 carbonate of lime used in industry is extracted by mining or quarrying. And how to get the pure carbonate of lime powder, the HGM&YGM grinding mill for carbonate of lime will be your best choice.

HGM&YGM grinding mill for carbonate of lime plant usually consists of grinding mill 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 HGM&YGM grinding mill for carbonate of lime:
HGM grinding mill for carbonate of lime 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 HGM&YGM grinding mill for carbonate of lime become more and more requires by various industries.

YGM grinding mill for carbonate of lime
YGM grinding mill for carbonate of lime is suitable for processing various non-flammable and non-explosive mineral materials with Moh’s hardness less than 9.3 and humidity less than 6%, it is widely used in the fields of metallurgy, construction, chemical industry, mining, highway construction etc,. The granularity of the finished powder size can be adjusted between 50 and 325 mesh (315-45 micron). Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore, carborundum, bauxite, rock phosphate, coal and other materials, total about 400 kinds of materials.

>>Working principle of HGM&YGM grinding mill for carbonate of lime:
Clirik HGM grinding mill for carbonate of lime working principle is when the HGM&YGM grinding mill for carbonate of lime 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 grinding mill 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.

When CLIRIK YGM grinding mill for carbonate of lime is working, big materials are crushed by jaw crusher to the required particle sizes, and carried by bucket elevator to the storage hopper, and are fed evenly and continuously by vibrating feeder into the main unit for grinding. The grinded powder are carried by the airflow from the blower to the classifier to be classified, the particles which meet the fineness enter cyclone collector through pipe, and are separated and collected there. They are discharged at the discharging valve to become finished products; the airflow is sucked to the blower by return pipe on the top of cyclone collector. The whole airflow system is a sealed circulation, and is circulated under positive and negative air pressure.
