Mining machinery industry as a pillar industry of the national economy, plays an important role in China's economic construction and social development. In mining, energy, transportation construction, and industrial production of raw materials and other industries, XZM series ultrafine mill grinding equipment as construction mining equipment and raw materials processing equipment, which aims to provide a steady stream of a large number of basic industrial goods and energy, very protection of the health of a large and rapid development of the national economy.

Based on years' research and development, engineer from Zenith designed this XZM series ultrafine mill which can be widely used for non-explosive and non-flammable materials such as limestone, gypsum, calcite, chalk, dolomite, kaolin, bentonite, steatite, mica, magnetite, iolite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite, barite, alunite, graphite, fluorite, phosphate ore, potassium ore pumice, etc. this type of mill is especially suitable for materials with medium and low hardness.

Frequent Questions From The Customers

Q: The Moisture Of My Gypsum Is About 10%, Is The Machine Suitable?

A: generally, our XZM series ultrafine mill is suitable for medium and low hardness material with moisture below 6%. But we can add a dryer before grinding and dry the gypsum until the moisture suitable for entering the mill. Because if the material with too much moisture, the heat produced while grinding will change the airflow volume while will lead to the low flour yield. So in the grinding process, the customer should avoid grinding material with too much moisture.

Q: How About The Fineness Of This Machine?

A: the output size of Zenith XZM series ultrafine mill can reach 2500mesh (5 um). The output size can be adjusted between 325 to 2500mesh. The one-time final product fineness can reach to D97 ¡Ü 5¦Ìm.

Q: Why Should The Customers Choose Zenith XZM Series Ultrafine Mill?

A: As a professional manufacturer in china, Zenith XZM series ultrafine mill has many advantages:

• High capacity and low consumption;
• Advanced grinding cavity design;
• High quality grinding media;
• Advanced intelligent speed control device;
• Large range of fineness adjusting.

Ultrafine Mill Working Principle

The main motor drives main axle and every layer rotating by the power of reducer. Dial drives numbers of rollers rolling and rotating in the ring by pintles. Big materials are crushed into small particles by hammer crusher. Then they are sent to store house by elevator. Vibrating feeder send the materials evenly to the middle of the upper dial. Under the function of the eccentricity, the materials fall into the ring to be pressed, crushed and milled into pieces by rollers. After the first crush, materials fall into the second and third layer. The pumping of the high-pressure centrifugal blower put the outside air into the machine. The coarse powder mill will be brought into the classifier.

Advantages XZM Series Ultrafine Mill

XZM Series Ultrafine Mill also uses a unique interchangeable blade curved blade, material can be oriented facade, so the roller mill ring, middle and lower grinding can make uniform wear, but also increases the effective working area, thereby increasing the yield. And the shovel blade portion with high wear-resistant alloy, long life, simply replace the replacement blade section, improved material utilization. Substantial costs savings every minute.

XZM Series Ultrafine Mill In The Application Of Gypsum

Work, bulk materials by hammer crusher into small particles by elevator into the storage hopper, electromagnetic vibrating feeder evenly to the material on the turntable in the middle, the host motor through reducer drive spindle and layers rotating turntable, turntable driven by dozens of circular shaft pin ring roller Raceway grinding ring rolling and rotating.

Material scattered in a circle under the effect of centrifugal force to the periphery, and fall within the grinding ring raceway is ring roller stamping, rolling and grinding, materials are crushed again fall into the first layer of the second layer and the third layer, by high pressure suction centrifugal fan of the external air into the machine, and within a selected powder material crushed by the third layer belt. Within the separator rotating worm crude materials fell regrinding, powder into the air into the cyclone powder collector by the lower part of the discharge valve discharge is finished, but with a small amount of fine dust in the air flow through the pulse dust collector after purification of exhaust through the fan and muffler.
