Brief Introduction of Stone Powder Making Machine

Stone powder making machine is an industrial grinding mill that can grind solid materials into ultrafine powder. It is usually used in Metallurgy, building materials, chemical and mine industries.


It is suitable for the superfine grinding of all kinds of crisp materials whose Moh’s hardness is below 7, such as calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, white mud, mica, refractory material, glass, total about 1000 kinds of materials.


Finished production fineness: 250meshes-2500meshes, 5-74 micron.


The capacity (ton/hour) ranges from 0.4T/H to 45T/H.


Max feeding size: 20 mm.

Working Principle of Stone Powder Making Machine

Stone powder making machine 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. 

After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of the first dial evenly by the electromagnetic vibrating feeder and feeding pipe.


The materials will be driven to the edge of the dial by centrifugal force and fall down into the ring, crushed and ground 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 the classifier.


The rotating turbo in the powder concentrator will make the coarse powder return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is 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.
