Calcium Carbonate Powder Making Machine

Information Calcium Carbonate Powder Making Machine Brief Introduction : Calcium Carbonate Powder Making Machine also is named Calcium Carbonate Powder Making Plant.Calcium Carbonate Powder grinding Machine,Calcium Carbonate Powder Processing Machine,Calcium Carbonate Powder Making Machine is suitable for grinding calcium carbonate into fine powder.   Calcium Carbonate Powder Making Machine is the new type mining equipment for making micro powders, fine powders，which is widely applied in the industries of metallurgy, mining, chemistry, cement, construction, refractory materials, ceramics, and so on.The purpose of the micro powder grinding millis for super-fine grinding materials with hardness less than 9 in Moh's scale and humidity less than 6 percent such as kaolin, limestone, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, carbon black, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment, up to 200 kinds. Calcium Carbonate Powder Making Machine Production line: consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems. Working Principle of Calcium Carbonate Powder Making Machine : 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 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. Technical Advantages of Calcium Carbonate Powder Making Machine 1.High Efficiency. Under the same finished final size and the same motor power, the capacity of the machine 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,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 (47-5 micron), and the product fineness can reach D97≤5μm. 5.Environment-friendly.
