At the enterprises of the mining and metallurgical complex, there is a problem of starting equipment with a heavy rotor. The article is devoted to the analysis of the causes of heavy start-up due to high impulse currents, and related problems of ore-grinding units, such as failure of the electric motor, increased operating costs for electricity, etc. The keys are proposed to solve not only these problems, but also the problems associated with reducing downtime when replacing the lining. The possibilities of a pneumatic chamber ratchet drive as an auxiliary starting drive of ore-grinding units are discussed. A pneumatic chamber ratchet drive was developed and studies were carried out, according to the results of which the possibility of using it as an auxiliary starting drive of ore-grinding units was determined.
