Name: Gypsum micro powder grinding mill
Model: HGM series
Powder Fineness Process Ability: 325-3000 mesh
Capacity: According to your demand about powder fineness, the finial capacity can be adjusted between 0.5-45 t/h
Use Range: can be used in more than 150 kinds of stone materials powder grinding, such as: calcite, calcium carbonate, dolomite, gypsum, carbon black, gypsum, kaolin, marble and so on
Application: mining, chemiscal, transport and many other different areas
Under the same finished final size and the same motor power, the capacity of the gypsum micro powdergrinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
The gypsum powder gridning mill ring and roller are forged by special material with high utilization,the lifetime can reach 2-5 years
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm.
The whole production is equipped with the dust removal system to ensure that the grinding powder is not discharged and the environmental pollution is avoided.

HGM series micro powder grinding mill mainly consist of main unit, classifire,powder collector,dust cleaner ,blower, muffler,sound-proof room,crusher,bucket elevator,storage hopper,and vibrating feeder.
1. After crushed by hammer crusher,the large materials become small ones and are sent to storage hopper by elevator .
2. Then evenly sent to the upper distribution plate of the turn plate by vibrating feeder and sloping feeding pipe.
3. When the grinding mill is at work,the main bearing and each dial are driven by electromotor of main equipment through reducer,and all the grinding rollers are rolling in the ring channels driving by dial through plunger.
4. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers. then the materials fall into multiple layers and to be crushed and ground continuously to micro powder.
5. The high-pressure air blower constantly inhales air within the grinding mill and, in turn,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 ari will go into the cyclone powder collector.
6. Most of the qulified powders will fall and exit from the discharging valve at the bottom;a small proprotion of the fine powders,with airflow,moves to by the sudden vibration of the filter bags,which is caused by the instantly ejected high-pressure gas controlled by the pulse valve.
7. The materials from the above two lost are sent by the conveyor at the bottom to get finished powders packed. In addition,filtered clean air will be emitted from the air outlet of muffler in the end.
