superfine powder grinding mill is a new type of ultrafine powder making machine with high efficient and low cost features. It is designed based on 15 years mill manufacture experience, through sufficient investigations, research and test and absorbing the mill advantages in this field. It has advanced technology which can replace other traditional grinding machines.

  

Features:

High efficiency

At the status of the same finish fineness and power, its production capacity per hour is twice as much as other jet mill, mixing grinder and ball mill.

Long lifecycle of spare parts

The ring and roller are forged by special material with high utilization. Under same grinding material and finish fineness, the spare parts’ useful life usually is one year, which is 2-3 times longer than impact mill and turbo mill. The service time can reach 2-5 years if grinding carbonate.

High safety and reliability

There are no rolling bearings and bolts in grinding cavity, so there are no problems caused by bolts shedding or wear of bearings and seal components.

High fineness and flexible adjustment

The final product fineness can be adjusted between 400 meshes and 3000 meshes, and the product fineness can reach D97≤5μm.

Environment friendly

The application of pulse deduster and muffler alleviate the dust pollution and noise.

 

Application

HGM Ultrafine Mill is equipment producing micro powders and ultrafine powders. It is mainly applied to mill non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, etc., totally more than 100 kinds material.

 

Production Line Configuration

The whole set HGM  Ultrafine Mill consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems.

 

Working Principle

The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
