Product Description

Application of Limestone Grinding Machine
Apply to non-inflammable, non-explosive and brittle materials with Mohs hardness scale under six. More than 100 kinds of materials, such as calcite, chalk, limestone, dolomite, kaolin, talc, magnesite, gypsum, graphite, pumice
The fineness of Limestone Grinding Machine can be controlled between 325~2500 mesh (47~5 micron).

Ultrafine Grinding Mill Features & Advantages
1. High efficiency
Under the same final size and power, the product capacity of Ultrafine Mill twice than jet mill and agitation mill.
2. Long lifetime of wearing parts
The lifetime of its wearing parts can reach to more than one year, about 2-5 times as long as that of vertical shaft impact crusher and turbo-mill.
3. Security and reliability
There are no rolling bearings and bolts in grinding cavity, so problems caused by bolts shedding or wear of bearings and seal components will never happen
4. High fineness of products
The product fineness can reach D97≤ 5μ M.
5. Environment friendly
The application of dust collector and muffler reduce the pollution and noise, which has reached national environment protection standard.

Ultrafine Mill Working Principle

Host motor through a speed reducer drives the spindle and the turntable, turntable driven by the column pin dozens of ring roll in the ring rolling and rotating raceway. Bulk material by hammer crusher broken into small particles by the hoist into a storage bin, electromagnetic vibrating feeder will even materials to middle upper turntable, material under the centrifugal force scattered to the circumference, and fall into the mill race was ring roller stamping, rolling, polishing and grinding ring, the first layer of crushed material in the second layer and the three layer, suction high-pressure centrifugal fan external air suction machine, and after the meal third layers of crushed into powder selecting machine. The turbine rotating powder machine in the coarse particles fall heavy grinding, fine powder with airflow into the cyclone powder collector and the lower part of the discharge valve discharge is finished, the air flow with a small amount of fine dust through the pulse dust collector after purification by the blower and exhaust muffler
