micro powder grinding machine is designed according to our many years manufacturing experience, absorbing the Swedish advanced machine manufacturing techniques. It is a new type of mill for making super fine powder through more than 20 times of test and improvement. Under the same conditions, the production capacity and fineness is three times and 300 mesh higher than that of Raymond and medium-speed mill respectively, exceeding the fineness limit of wet stirred mill, which has been the first choice of high-tech, efficiency and energy- saving mill.
micro powder grinding machine is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials 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.,with Moh's hardness below six levels.
Under the same final size and same motor power, the capacity of micro powder grinding mill is twice as much as jet mill, mixing grinder and ball mill, and its energy consumption is decreased 30%.
Long service life 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 service life of spare parts is about one year, which is 2-3 times longer than impact mill or turbo mill. Furthermore, the lifetime can last 2-5 years for grinding calcite carbonate.
High safety and reliability
For 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 and flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 2, 500 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
It is featured by convenient adjustment and more uniform particle size.
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After being crushed by hammer crusher, big materials become smaller and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial under centrifugal force and fall down into the ring, being crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill for re-grounding, while the fineness will be mixed with the air and goes into the cyclone and be discharged in the discharge bin, which is located at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
