Vermiculite pulverizer
Vermiculite pulverizer
Application of Vermiculite pulverizer:
1.Used to permit slow cooling of hot pieces in glassblowing, lampwork, steelwork, and glass beadmaking
2.Used in in-ground swimming pools to provide a smooth pool base: Finer grades of exfoliated vermiculite plus Portland cement may be combined either on site or a factory premix to provide a base for swimming pool vinyl liners. These mixes are either pumped into place using a rotor stator pump or hand poured.
3.Used in commercial hand warmers
4.Used as a sterile medium for the incubation of reptile eggs
5.Light-weight insulative concrete
6.Used in AGA cookers as insulation
7.Used in explosives storage as a blast mitigant
8.Used to absorb hazardous liquids for solid disposal
9.Used in gas fireplaces to simulate embers
10.Used as part of a substrate for fungi cultivation
 
Vermiculite pulverizer: the granularity (or final size) of the finished products can be freely adjusted between 325-3000meshes (0.045-0.0057mm), and the capacity (ton/hour) ranges from 0.4T/H to 12T/H.
 
Advantages and features of vermiculite pulverizer:

l、 High efficiency
Under the same finished final size and the same motor power, the capacity of vermiculite pulverizer is twice as much as jet mill, mixing grinder and ball mill.
2、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 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
3、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.
4、 High fineness and flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≦5um.
5、Environment-friendly
The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
 
Working principle of vermiculite pulverizer:
 
HGM series vermiculite pulverizer mainly 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 vermiculite 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 vermiculite 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.
