Calcium Carbonate Grinding Mill Introduction
Calcium Carbonate Grinding Mill also is named calcium carbonate grinding mill. Calcium Carbonate Mill (powder grinding mill) is suitable for grinding calcium carbonate into fine powder. After being grinded by the Calcium Carbonate Grinding Mill, the fine powder size can be 300 mesh to 3000mesh for industry usage. The powder output size of Calcium Carbonate Mill (powder grinding Mill)can be adjusted continuously according to the customers’ demand.
Application of Calcium Carbonate Grinding Mill
HGM Series calcium carbonate grinding mill is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Moh’s hardness under six, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite and vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rockphosphate, Kalium ore, pumice, etc., totally more than 100 kinds of materials.
Working Principle of Calcium Carbonate Grinding Mill
Calcium carbonate grinding mill is mainly formed by mill body, blower fan, ultra-fine analyzer, finished product cyclone container, bag de-duster and air pipe. The elevator, storage bin, electric control cabinet, powder feeder and crusher are optional for the demands of customers.
When the grinding mill is at work, the main bearing and each dial are driven by electromotor through reducer, and all the grinding rollers are rolling in the ring channels driving by dial through plunger. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers. The high-pressure air blower constantly inhales air, airflow with crushed materials are brought to 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 and exit from the discharging valve at the bottom; A small proportion of the fine powders, with airflow, moves to the dust cleaner. The materials from the above two lots are sent by the conveyor to get finished powders packed. In addition, filtered clean air will be emitted from muffler in the end.
Advantages of Calcium Carbonate Grinding Mill
1. High Efficiency
Under the same finished final size and the same motor power, the capacity of calcium carbonate grinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
2. 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 2-3 times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
3. 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.
4. High fineness, flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (74-5 micron), and the product fineness can reach D97≤5μm.
The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.
6. Advanced intelligent speed control device
Convenient adjusting, more uniform particle size.
