Improving the method of crushing coal charge components
Investigations were conducted to compare the operating efficiency of hammer crushers with screens and grates. It was found that the replacement of grates with screens in hammer crushers improved the granulometric composition of the crushed coal, decreased the quantity of breeze classes, and increased the bulk density of the coking charge. The efficiency of crusher operation depends on the degree of wear of the beaters and the size of the gap between the beaters of the moving rotor and the screens. The service life of the screens was six times greater than the service life of the grates: the use of screens permitted an improvement in the operation of hammer crushers and the working conditions of the service personnel.
