Issue 41/2014 - Ultra-fine roller grinding contributes to non-mineral deep processing

In order to improve the current situation of domestic non-metallic mineral powder processing equipment and enhance the level of non-metallic mineral powder deep processing technology, Zhejiang Fengli Crushing Equipment Co.
, Ltd.
has innovated and developed an ultrafine crushing equipment comparable to similar foreign products - CGM ultrafine roll grinding
on the basis of introducing advanced powder technology from Germany.
Recently, the equipment was rated as a new product
in Zhejiang Province in 2014.

Ultrafine roller grinding is a kind of internal grading high-pressure ultrafine roller milling, which can complete the two processes of micronized crushing and micronized sorting at the same time, suitable for ultrafine crushing of non-flammable and explosive materials with a humidity of less than 8%, such as kaolin, limestone, calcite, talc, graphite, carbon black, etc.
, and a hardness below 6 on the Mohs scale, which can meet the needs
of the non-metallic mining industry for this type of equipment.

Compared with Raymond mill and airflow crusher, the production efficiency of the equipment is more than doubled under the same power conditions, and the grinding pressure of the grinding wheel to the material is increased by 30%~40%
under the action of high-pressure centrifugal force.
The output of the equipment is large, and when crushing calcium carbonate with a fineness of 10 microns, the output can reach more than
1 ton per hour.
In addition, the fineness index of the crushed product of the equipment can reach the fineness index of the fluidized bed air mill, and the dust removal effect fully meets the national dust emission standard
.
