Method of Operation
Material is closed through a cooling screw conveyor and embrittled with the help of Liquid Nitrogen. Size is reduced in the cutting chamber or Mill. Embrittled material and Mill Grinding produces fine powder. Then the pulverized material is pneumatically conveyed to screen through cyclone and desired particle size is achieved.
Area of Application
Cryogenic Pulverization System, incorporating the different designs of mills, produces High Quality Powders from extremely Heat Sensitive Material and Elastomers.
Pulverizing occurs at Low Temperature (-70°C to -150°C) and High Impact Speed. Material is cut after making it brittle, producing quite fine powder which ensures optimum Flowabilityand high bulkdensity.
Particle sizes produced are in the range of d97 = 500 µm up to d97 = 80 µm.
Advantages
- Excellent powder characteristics
- Cubic particles with good flow properties & Bulk density
- High throughput rate at very high fineness
- Low specific energy consumption
- Quick and easy cleaning
