Small Capacity Lab Grinding Mill For School , Cryogenic Fine Powder Grinding Machine

Lab Fine Cryogenic Grinding Machine for School Small Capacity

This Lab Fine Cryogenic Grinding Machine for School Small Capacity is applied in grinding various materials which can't be shattered in room temperature. For example: nylon, polyester, polypropylene and polyethylene, thermoplastic elastomer TPU, TPEE, PA,copolymerization of nylon, polyester,Polytetrafluoroethylene,EVA, food industry (chili powder), Chinese herb and so on.

Features:

• The pulverized powder size can reach to 700 mesh.
• In the process of pulverizing, a closed loop system is formed by cold source, which makes full use of energy and energy saving.
• Using liquid nitrogen as medium achieves realize the function of ultra-low temperature pulverizing, avoid the explosion and oxidation.
• The cold medium temperature can be adjusted according to the brittleness point of materials, and it can be cooled to -196℃ at most.

This cryogenic grinding machine use liquid nitrogen as cooling medium. When crushed material is achieved at the brittle fractured state,it goes into mechanical pulverizing chamber and repeatedly impacts,collides,shears,mills by high speed rotation of blade and gear to reach the optimal crushing effect. The milled material has airflow grading machine to classify and collect. If the fineness of material does not meet the requirements,it will return silo to continue grinding. The liquid nitrogen mostly can be cyclic utilization.

We warmly welcome your visit!
