Fine grinding of thermoplastics by high speed friction

Fine grinding of thermoplastics by high speed friction

Apr 01, 2021 High speed friction grinding has been used to grind plant and food substances in water but never been explored for grinding of thermoplastics like polylactic acid (PLA), low and high density polyethylene and polypropylene. Such grinding was investigated in this work and was made possible by using 0.5% guar gum solution instead of just water because increasing the viscosity of water reduced

A preliminary simulation model for fine grinding in high

Jun 25, 2004 In a hammer mill designed for fine grinding , it can be assumed that entering feed is rapidly broken into particles that are carried round and through the mill as a solid–air suspension. It will be assumed that the hammers impact this suspension at a sufficiently high velocity that the Newtonian drag coefficient applies, that is, the system
