HGM 90 Rock Pulverizer

Descripción del producto

Working principle of HGM *0 rock pulverizer:

HGM *0 rock pulverizer consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
 
After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe.
 
When the rock pulverizer is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.
 
The high-pressure air blower constantly inhales air within the rock pulverizer 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 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, and clings to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots 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.
 
Features and advantages of HGM *0 rock pulverizer:
● High Efficiency
Under the same finished final size and the same motor power, the capacity of rock pulverizer is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased *0%.
● Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is **3 times longer than impact mill or turbo mill. Furthermore, the lifetime can reach **5 years for grinding calcite carbonate.
● High safety and reliability
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.
● High fineness, flexible adjustment
The final fineness of the grinding materials can be adjusted between **5 meshes and ***0 mesh (***5 micron), and the product fineness can reach D*7≤5μm.
●Environment-friendly
The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.
●Advanced intelligent speed control device
Convenient adjusting, more uniform particle size.
