Fineness of 3000 mesh is a high processing, is the domestic many flour mill equipment production enterprises cannot reach grinding fineness. For many material hardness is also the important factors that affect processing fineness, processing more than 3000 mesh of ultrafine powder with what ultrafine mill?

Common flour mill in the market in China can be roughly divided into: Raymond mill, vertical pendulum pulverizer, hanging roller mill, high pressure micro powder mill, straight through the centrifugal mill, overpressure trapezium mill, three-ring medium speed mill, six types of grinder. Raymond mill and the high pressure roller suspension grinder processing fineness below 400 mesh.


The vertical pendulum pulverizer is applicable to processing in mohs hardness below 7, humidity in humidity below 6% of inflammable, explosive materials, fineness in between 0.18 0.015 (80-800 mesh) any adjustments, processing fineness also cannot achieve 3000 mesh. And high pressure micro powder mill and overpressure trapezium mill processing fineness generally are below 400 mesh.

While Shanghai clirik company produces the three-ring medium speed highest superfine mill processing fineness can reach 3000 mesh, preliminary to satisfy the enterprise need for high fineness of materials processing, the product fineness can achieve d97 5 um or less at a time.

And the emerging of ring spinning superfine grinding machine has the following features:

Grinding force: roller grinding force generated by the force from two high pressure spring preload (approximately 4000 kg), 4 r3216 Raymond mill grinding force three times.

Unique way of grinding: the ring spinning superfine grinder is parallel to the roller suspension on the inside of ring cavity, do not contact directly grinding roller and grinding ring, ring spinning roller rotation, through material roller in both root spring high pressure under the action of pre-tightening force and make the material crushing and grinding. Due to the grinding roller and grinding ring not direct contact with the ground material iron content is low, and not to drop the white degree.

Is greater: for the grinding surface of ring spinning through material roller rotation, rollers and rings reverse relative motion, makes the grinding roller and grinding ring grinding area twice of the roller.

4)The finished product fine granularity: finished size up to more than 2000 mesh.
5)High output, low energy consumption.

In short, in the present circumstances, the domestic production of flour mill equipment in addition to three-ring medium speed mill and ring spinning superfine mill, other processing equipment is difficult to achieve 3000 fineness, the enterprise must recognize when the choose and buy equipment.
