calcite grinding mill&equipment
Clirik calcite grinding mill is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with mohs’s hardness under six, such as calcite, kaolins, limestones, calcite, barites, carbon black, mica, quartz etc. With the development of high-tech industry, fine and superfine powder is widely applied in various fields, so Clirik calcite grinding mill become more and more requires by various industries.
Working principle of calcite grinding mill:
Clirik calcite grinding mill mainly consists of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
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.When the grinding mill 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.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.
Features of calcite grinding mill:
Under the same finished final size and the same motor power, the capacity of micro powder grinding mill is twice as much as jet mill, mixing grinder and ball mill.
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.
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.
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≦5um.
The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
Through long-term arduous technology research and international communication, our product quality has been in line with international level, winning a world-wide acclaim and honor, and our products are exported to ninety countries and regions like Tanzania, Nigeria, South Africa, Kenya, Turkey, Saudi Arabia, Philippines, Indonesia, Malaysia, Vietnam, Mexico, Brazil, Russia, Uzbekistan, Australia, etc.
