Abstract
The use of different crushers to obtain the required size of the stone material. This work presents experimental studies of the characteristics of a crusher with a complex movement of working organs. The objectives of the study are, a sieve analysis of the obtained product (crushed stone) and the determination of the optimal speed of the working bodies (rolls) to obtain high-quality cubic shape crushed stone. In the experiment, the raw material is fed into the working space (into the crushing chamber) through the hopper and moves by a flat flow between the rollers. The edges of the rolls roll symmetrically from two sides to the flow of material, approaching in the area of the crushing zone and diverging in the region of the unloading zone. The authors determined the optimal rolls for obtaining high-quality cubiform crushed stone (over 80%). As a result, of the research, it was established that the grain composition of the fraction is within the standard of the Republic of Kazakhstan 1225-2003 t.3 – is obtained cubiform crushed stone, with an rotational speed of rolls of 100-120 rpm.
