Mar 28, 2008· As was explained in our interim response letter of May 16, 2007, your inquiry raised complex issues and required additional time for an adequate response. You requested clarification of OSHA's requirements for spray finishing operations, specifically asking if a spray booth is required when the substance being sprayed is water-based paint.
The working principle is that cement is removed from the mill before over-grinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. Recirculation factor, that is, the ratio of mill throughput to fresh feed is up to three.

Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set. Water spray is controlled with mill outlet gas or material temperature. A hardware interlock is recommended with mill main drive to avoid accidental spray in mill.
