HGM Three-ring Medium-speed Micro Powder Grinding Mill

Introduction:

HGM three-ring medium-speed micro powder mill is currently the most advanced dry-process non-metallic mineral ultra-fine powder grinding equipment. The material crushing and powder classification are placed in the same machine body and operate independently, with a compact structure. The finished product fineness can be adjusted to 1400-3000 mesh. It is an ideal equipment for dry-process production of heavy calcium ultra-fine powder.

Application: 

Mining, smelting, metallic minerals, building, highway, railway, water conservancy and chemical industries.

Working principle:

When HGM grinding mill is at work, the main bearing and each dial are driven by electromotor through reducer, and all the grinding rollers are rolling in the ring channels driving by dial through plunger. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers.   The high-pressure air blower constantly inhales air, the airflow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner. The materials from the above two lots are sent by the conveyor to get finished powders packed. In addition, filtered clean air will be emitted from muffler in the end.

Advantages:

1. High yield: capacity is 40% higher than that of jet grinding mill and stirred grinding mill.
   

2. Adjustable fineness: powder selector can be configured according to the users' requirements on yield fineness and sieving rate.

3. No rolling bearing: there is no rolling bearing and screw inside the mill, so users are free from worries about damages on bearing or its sealing parts.

4. More eco-friendly: it is equipped with efficient pulse dust collector, no dust pollution generates during operation of the entire milling system. Silencer and noise elimination room are configured to reduce noises.

Parameters:

Note: 

1. The output will vary according to different materials, feed particle size and other factors. 

2. Technical parameters are subject to change without prior notice.
