The Kason CAM 1300 air classifier mill provides impact grinding and air classification to produce fine grinds at rates up to 16.5 tons per hr.
Subsequently, product and grinding media flow into the area of an intensive impact grinding, which results from the interaction of rotor and stator pegs.
Then, the product passes down the outer annular gap into an area of intensive impact grinding, which results from the interaction of rotor and stator pins.
It holds 20 cups of grain at a time, and its impact grinding mechanism is self-cleaning.
Impact tests and impact grinding may subject the specimen to both tensile and compressive forces.
At a time to failure of 100 [[micro]seconds], which is comparable to the time scale for deformation during impact grinding, the brittle-ductile transition for PVC is estimated to be about 12 [degrees] C for PVC and -35 [degrees] C for PET.
Impact grinding experiments were done on chips from post-consumer bottles of PVC and PET.
Because the unit uses impact grinding rather than knife cutting, there are no knives to sharpen.
(3) have shown that tensile failure occurs for PVC and PET under impact grinding conditions.
(3) have shown that PVC shows a brittle-ductile transition under impact grinding conditions at 0 [degrees] C (it fails in a brittle mode at lower temperatures).
Single post-consumer bottle flakes, roughly 6 mm in length, were subjected to impact grinding in order to gain information about the progeny particles.
