Improvement of the Technology of Preparation of Clay Raw Materials for the Production of Refractories

We propose an engineering solution of a screen with elevated efficiency of separation of clay rock masses. The most rational design of undriven bar screens (namely, cantilever and spring-loaded screens) is determined. We present a mathematical model and a procedure for the evaluation of the parameters of screens. It is shown that, in the case of selection of the proper parameters for the grates of the screening surface, the screens can be used for the purposes of screening of clay rock masses.
