For ultrafine powder grinding mill machines and crusher equipment we will not feel strange,they are mine mechanical equipment, they are also used for grinding stone crushing equipment, but because of ultrafine powder grinding mill and crusher equipment material crushing principle and fineness different, so we have the crusher equipment and ultrafine powder grinding mill points.
HGM series micro powder grinding mill mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
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 turn plate by vibrating feeder and sloping feeding pipe.
When the grinding mill is at work, the main bearing and each dial are driven by electromotor of main equipment through 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 where the materials are repeatedly pressed, crushed and grinded by the rollers. Then the materials fall into multiple layers and to be crushed and ground continuously to micro powder.
Hammer crusher mainly consists of frame, rotor, support iron and grate bars. The frame is divided into two parts: upper part and lower part which are welded by steel plates after being cut. Liners made of high manganese steels within the frame can be replaced after being worn out. The rotors consist of the turn plate, pin shafts, and hammers which are grouped regularly in the main shaft. The motor drives the rotors to rotate quickly in the crushing cavity, and hammers spread outward as a result of centrifugal force from the rotation of the rotors. Large materials entering the crusher through the feed inlet are stricken, impacted, cut and ground by the high-speed hammers to small size. Qualified materials crushed will be screened out and exit from the gap of the grate bars while the unqualified will be left in the crushing cavity to be further hammered and ground until reach the standard size. The size of the final product can be adjusted by changing the grate bars. The gap between the rotors and the grate bars can also be adjusted according to different requirement.
