Used Ultrafine Mill introduction
used Ultrafine Mill
for almost 30 years, zenith has being specializing in all facets of Grinding Mill design and maintenance. especially to xzm series ultrafine mill, it’s growing more and more popular with its reliable technology and perfect after-sale services. xzm series super thin mill(ultrafine mill) is on the bases of our company’s production experience for more than 15 years. we absorb advantags from the same trade abroad and at home. we review, research and try on 12 kinds of mills and horizontal hammer crushers. and finally we developed this high-efficiency and low-cost super thin mill by investigation and trial.
zenith ultrafine mill is specially designed for super fine powder grinding. zenith is a progressive china-based enterprise. zenith xzm series ultrafine mill is widely for micron powder producing. the output size can reach 2500mesh (5um). it is suitable to grind the material with middle and low hardness, moisture below 6%, and the material should be non-explosive and non-flammable, such as: calcite, chalk, lizenithne, 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 product can be adjusted between 325-2500 mesh.

used 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.
the greatly massive material arrives stave after the jaw type breaker needs the granularity, by the elevator the material delivers to the storage bin, passes through again vibrates the feeding engine to send in the material even quota the main engine to rub continuously indoor carries on the attrition, after the powder rubs the powder along with the air blower air current rise, carries on the graduation after the analyzer, conforms to degree of fineness powder to have control over the road along with the air current to enter in the bypass collection dusting equipment, carries on the separation collection, after leaves the powder valve to discharge namely for the end product powder. the air current by the bypass collection dusting equipment upper extreme return air tube inspiration offcenter drawing fan, this aircraft entire air current system is the negative pressure airtight circulation, had guaranteed produces the scene environmental protection health.
used ultrafine mill structure & features
used ultrafine mill
1. high efficiency. under the same condition of finished particle size and power of motor, the output is 40% higher than airflow mill and whisk mill.
2. environmental protection. pollution and noise are lightened by using deduster and muffler so as to reach the requirement of national environmental protection.
3. high safety. no axle tree or bolt is used in the grinding chamber, so there will be no worn out problem of bearing and sealing parts, and also no loose of bolts.
4. finished size can reach to d97≤5μm.
5. high using rate of spare parts.
6. high capacity and low consumption.
7. advanced grinding cavity design.
8. high quality grinding media.
9. advanced intelligent speed control device.
10. large range of fineness adjusting.
