Collision Plate Type Supersonic Jet Mill Model SPK
Up to double the production capacity of conventional machines.
Principle
- Supersonic vortex airflow pulverize particles to collide with the center of the collision plate for pulverization.
- Coarse powder is circulated back to the grinding section.
Features
- Special grinding nozzle (SPIKEJET) reduces the spread of supersonic airflow and enables grinding in the center of the collision plate.
- Vertical grinding method reduces bias and enables efficient pulverization by uniformly impacting the collision plate.
- Up to double its production capacity of our conventional machines.
- High impact force and high pulverization efficiency enable to grind materials that were previously impossible to grind.
- Cooled type (optional) enables grinding of low-melting-point materials.
