Ultrafine mill Features:
1. Reliable
2. High capacity and low cost
3. Easy adjustment of product fineness
4. Clean, environmental protection
Zenith XZM Ultrafine mill is widely used in making fine powder or micro powder, a new kind of machine for producing fineness and ultra-powder. It is mainly used for grinding the material with middle and low hardness, below 6% moisture, and the material should be non-explosion and non-flammability, such as: Calcite, chalk, limestone, dolomite, kaolin, bentonite, steatite, mica, magnetite, iolite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate ore, potassium ore pumice, etc. The size of the finished production can be adjusted between 325-2500 mesh.
Application:
XZM Ultrafine mill is a machine for producing fineness and ultra-powder. It is mainly used for grinding the materials whose hardness is middle and low, moisture below 6%, and Moths hardness should be blow 9 grade and non-explosion and non-flammability, such as: Calcite, chalk, limestone, dolomite, kaolin, bentonite, steatite, mica, magnesite, illite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate ore, potassium ore pumice, etc.
Working Principle
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of roller which are rolling in the ring, which are driven by dial through plunger. After crushed by hammer crusher, the big materials become small sizes ones and they are sent to storage bin by elevator. The electromagnetic vibrating feeder will send them to the middle of first dial evenly, the materials will be driven to the EDGE of dial by centrifugal force, and fall down into the ring and crushed and grinded by roller, then the materials will fall down into the second and third ring, and crushed and grinded. The high pressure centrifugal blower will inhale air from the outside and blow the materials which are grinded in the third ring to powder classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged the discharge valve which is in the bottom of it. The air which mixed with very little fineness will be purified by impulse duster and discharged by blower and muffler.
Composition and Structure
The standard configuration of XZM ultrafine mill consists of main unit, powder classifier, double cyclone collectors, pulsed filter, blower, motor, pipes and muffler. The optional accessories include jaw crusher, hammer crusher, elevator, feeder, and control cabinet.
There are bearing pedestal and blowing case on the main machine base. There is grinding case on the blowing case, whose middle part has multilayer dial equipping on the main bearing. On each dial, there are numbers of roller, and there are corresponding ring for each dial. There are two class screwing gear reducer and electromotor in the base of main machine. The powder classifier is equipped on the top of grinding chamber.
