grinding tought,thermoplastic material at cryogenic tempratures means that plastic are brittle enough to be very fine partical size
silos, mechanical grinder, fan, cyclone, shaker, liquid nitrogen tank and other components
The system widely uses for a variety of materials at room temperature can not be crushed
1- thermoplastic material: PP, PE, PS, EVA, PTFE, ABS, MBS, PA, PET.......
2- TPU, Nylon, HDPE, LDPE, LLDPE, rubber, PPT......
3- engineering plastic material: PA, PA6 PA12 PC POM PBT PMMA........
4- special engineering plastic: PEEK, LCP, PTFE, PES, PAI, PAR.......
5- modified plastic: ABS, PP, PVC, PC
6- modified enginerring plastic: PPO, PA, POM, PC, PBT, PET, PSU....
7- plastic rubber materials, kinds of mater batch or pigment: such as white master batch
8- food industry: frozen food pulverizer, chili powder, pepper, white pepper, cinnamon powder ......
9- chemical industry: medicine powders
General food at minus 10-15 degrees can crush crushed to 200 mesh or more. Plastics can be crushed to about minus 30 degrees .
2-more uniform particle size distribution
4-process coolling/temperature control
5-smaller feed ,biger capacity, smaller consumption of nitrogen
main pulverizing motor power:Siemens
How does it work?
This deep cold grinder system takes liquid nitrogen as cold source and use the brittleness of
the stuffs under cold temperature.When the cold brittle stuffs enter into the pulverized through the
integrated effect of mutual repeat impact,collision,shearing,rubbing between stuffs and stuffs,stuffs and vane,stuffs and gear plate.
The stuffs after pulverization will be classified and collected.the particles which haven’t
reached the size requirement will be returned back to the bin and pulverized again.most of the cooling air will be also recycled.
