The article describes the properties of heat resistance and frost resistance of a cone crusher when crushing rocks, and it is established that the transported stones have an abrasive effect on the cone crusher during crushing. Efficiency, of the crushing chamber, the composition of stones in the deposit, the percentage of their correct use of crushing power during construction work. The abrasive wear of the working bodies of the conical crushers was revealed.
