Polish-Type Water Pulsated Jigs

The purpose of this paper is to review recent designs of polish water pulsating jigs in last years. This article shows basic technical para - meters of polish jigs on the basis of its high capacity per unit with high imperfection in coal preparation plant or high efficiency separa - te gravel and sand in mineral preparation plant. The adoption of a computer-controlled system in the design of the jigs have provided several advantages, for example control of water pulsation within any selected cycles, automatic control over the collection of the bed, automatic control over the loosing of the bed, relatively low costs of cleaning and its overall “clean” technology with potential ability to reuse “waste” [3, 5]. The latter aspect of coal or gravel and sand preparation is particularly important for environment protection.
