SOME MECHANICAL REQUIREMENTS OF PLANT FOR THE ROLL-COMPACTING PROCESS

Abstract

The paper is based on a survey of recent literature on the art of roll compacting made for the purpose of producing criteria for use in the design of processing plant. After a definition of the duty required of such plant has been given, the type of mill necessary is discussed, and the various systems used for dispensing powder are considered in relation to the operational requirements. The process of roll compacting and the resulting strip conditions are discussed in relation to the variables in physical dimensions of plant and product. Certain criteria applying to the roll-compacting process are mentioned, and the wide variation in strip speeds employed by different investigators is noted. It is considered that roll loads as given by some investigators may be higher than those actually obtaining in practice, and some explanation of this claim is given. Finally, brief reference is made to the lubrication of the rolls or the powder during the compacting process and to subsequent processes including sintering, densification, and cold rolling.
