Chalk powder grinder machine; chalk powder grinder series is mainly applied to grind non-inflammable, non-explosive and brittle materials with Mohs’ hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, and talc etc, totally more than 100 kinds of materials. Product fineness can be controlled between 300~3000 mesh (47~5 micron)
HGM series Chalk powder grinder machine; chalk powder grinder series mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
A brief introduce of chalk and the use of chalk:
Chalk also known as clay powder, clay sub, of white Haniyasu soil, white good, Bai Shan. Chalk is the sediments of a fine calcium carbonate and is a variant of the calcite. As the mineral, chalk generally used to make the chalk and other products. Clirik powder grinder machine which is also called powder grinder; micro powder grinder; industrial powder grinder; fine powder grinder; powder grinder series.To make chalk into powder, we have Chalk powder grinder machine; chalk powder grinder series.
The use of chalk is different in different grinding fineness, the industry is divided into four different specifications: solo, Flying, three flying four fly, respectively, for the various industrial sectors.
Solo flour: used in the production of anhydrous calcium chloride, sodium dichromate production auxiliary materials. The main raw material of glass and cement production. In addition, it is also used in building materials and poultry feed.
Flying powder: used in the production of anhydrous calcium chloride and glass raw materials, rubber and paint white filler, as well as construction materials.
Three flying powder: used as plastics, paint putty, paint, plywood and paint filler.
The four fly powder: used as filler wire insulation, rubber molded products, as well as asphalt linoleum filler.
Working principle of Chalk powder grinder machine; chalk powder grinder series:
After crushed by hammer crusher, the large materials become small ones and are sent to 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 Chalk powder grinder machine; chalk powder grinder series 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 Chalk powder grinder machine; chalk powder grinder series and, in turn, the airflow 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 and 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 and advantages of Chalk powder grinder machine; chalk powder grinder series:
● High Efficiency
Under the same finished final size and the same motor power, the capacity of Chalk powder grinder machine; chalk powder grinder series is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
● 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.
● 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, flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm.
●Environment-friendly
The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.
●Advanced intelligent speed control device
Convenient adjusting, more uniform particle size.
