Calcium carbonate powder mill is designed by our R & D department on the basis of many innovations and tests. Thousands of customers have proved that our equipment has outstanding performance, stable quality and convenient operation and maintenance. It is the ideal equipment for fine grinding.
In addition to grinding carbonate powder, calcium carbonate powder grinding mill can also be widely used in chemical, metallurgy, non-metallic ore and other industries. Especially in the non-metallic mining industry, for mohs hardness below 6 degrees of non-flammable, non-explosive, barite materials, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, fly ash, etc., can use calcium carbonate powder mill for grinding. , more than 1000 kinds of materials.

Calcium carbonate powder 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 being crushed by a hammer crusher, the large materials become small ones and are sent to a storage hopper by elevator.
And then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe.
When the calcium carbonate powder grinding mill is at work, the main bearing and each dial are driven by the electromotor of the main equipment through a 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. And the materials are repeatedly pressed, crushed, and ground by the rollers in grinding chambers. Then the materials fall into multiple layers and to be crushed and ground continuously to micro powder.
The high-pressure air blower constantly inhales air within the grinding mill. In turn, the airflow with crushed materials is 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.
● High Efficiency
● Long lifecycle of spare parts
● High safety and reliability
● High fineness, flexible adjustment
● Advanced intelligent speed control device
Under the same finished final size and the same motor power, the capacity of the calcium carbonate powder grinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
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 an impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate. The lifecycle of spare parts is variable for the material’s hardness.
As no rolling bearings or screws in the 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 150 meshes and 3000 mesh (74-5 micron). Environment-friendly
The application of pulse bag filters and mufflers greatly alleviates dust pollution and noise.
Let the material feed into the machine evenly, adjust the main speed to fit for ground material, the fineness more stable. To increase the capacity and efficiency, reduce the power consumption.
