It consists of (Fig. 1) a cylindrical body equipped with two loading nozzles installed tangentially and two discharge nozzles installed coaxially to the body. In addition, blades in the form of plates are fixed on the inner cylindrical surface of the housing, which are arranged in rows along the housing between the outlet ports of the discharge pipes.
The disintegrator works as follows: clay material in the form of a hydraulic mixture under pressure enters the housing simultaneously through two loading nozzles. Due to the tangential orientation of the nozzles, the flows acquire a rotational motion towards each other.
As the streams move, the clods of clay repeatedly meet with the blades. On the front and opposite sides of the blades, there are zones of high and low pressure, passing through which the lumps quickly become soaked with water, and when interacting with each other and hitting the surface of the housing, they collapse.
In the middle part of the body, both streams, swirled in opposite directions, meet, which is accompanied by intense abrasion with the release of mineral grains. The hydraulic mixture continuously entering the housing displaces the finely dispersed clay and the mineral grains released from it move to a smaller radius and then out through the discharge pipes.
The graph (Fig. 2) shows the test results of the GCD-400, installed at the factory in a production line operating parallel to the main one. The top product of butara with a grain size of -30+5 mm, which passed the stage of disintegration in a standard scrubber, was processed. The ratio of the analyzed size classes -30+10 and -10+5 mm in this product was 1:2.
