Abstract
The description of a single-roll crusher developed at Siberian State Industrial University with a forced feeding of the crushing material into the fracture zone due to the abutment located on the roll is provided. The forces acting on the crushed material from the side of the roll and the fixed cheek are defined in function of the force magnitude acting on the material from the side of the stop. On the basis of the obtained results, it is determined that when the force applied on the side of the abutment is constant, the friction coefficient between the cheek and the material to be crushed decreases, the forces acting on the fractional piece on the side of the roll and the cheek increase. It results in the reduction of energy consumption required for crushing of all other things being equal, which lowers the energy capacity of the single-roll crusher operation with forced feeding of material into the crushing zone.
