- Quinn Process Equipment - M-002
For use in primary or regrind circuits in mineral, chemical, or industrial pilot plants or small commercial size applications. Flexible for wet or dry grinding in open or closed circuit as a rod, ball, or pebble mill.
Typical grinding applications include: copper, lead-zinc, fluorspar, uranium, molybdenum, etc.; are processing pilot plants; high grade industrial materials to liberate values prior to recovery by subsequent processing; grinding of chemicals or material such as limestone for use as reagents.
Quinn grinding units are designed for 24-hour day continuous abrasive duty. They offer a great deal of flexibility. As standard or with minor adaptation, they may be operated
A. as a rod, ball, or pebble mill.
* Capacity based on wet grinding medium ore to 65-mesh.
