XZM Ultrafine Mill

Brief Introduction
　XZM Ultrafine mill is new processing equipment of high efficiency and low consumption, which is designed by our own engineers and technicians of multiple innovation, test and experience of more than twenty-year in mill manufacture. This mill has absorbed many advantages of home and aboard mill-manufacturing technique. It is the representation of leading level of high quality grinding machine. It has been proved that our product has perfect performance and high quality by many customers.

Features
1.High capacity and low consumption
Under the condition of dealing with same final fineness and using same power, the capacity of XZM Ultrafine mill can be improved 40% than the traditional machines, while the consumption reduces greatly, comparing with jet mill and mixing mill.
2.Easy fineness adjustment and high fineness
The final fineness can be adjusted according to requirements, and the fineness can reach D97≦5um.
3. Reliable Security
There is no rolling bearing and bolt in the mill chamber, therefore, the bearing and sealing elements will not wear out easily, and the bolts will not loose to make damage to the equipment.
4. Clean, environmental protection
Equipped with pulse filter and silencer, the mill reduces dust and noise greatly, which reaches National Environmental-protection Standard.
Application:
　　XZM Ultrafine mill is a new kind of 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 its Moths hardness should be blow 9 grade and 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.

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, 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 then grinded by roller. The materials will fall down into the second and third ring, 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 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.

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’s base. There is grinding case on the blowing, 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 classes screwing gear reducer and electromotor at the base of main machine. The powder classifier is equipped on the top of grinding chamber.
