FIELD: mining industry.
SUBSTANCE: invention relates to devices for grinding ore and other materials and can be used, for example, in the mining, cement, power, metallurgical, lime and porcelain industries, as well as in the chemical industry. Mill contains cylindrical rims 1, rigidly connected, for example, with drum, support-drive rollers 3, installed on both sides of at least one cylindrical rim (1), driven into rotation by electric motors 12 located coaxially to support-drive rollers 3. At that, the mill contains installed with possibility of swinging support-drive units 11, which are double-arm levers, or additional double-arm levers 21, in which two support-driving units 11, or additional double-arm levers are installed with possibility of swinging, in which two said additional double-arm levers 21 are installed with possibility of swinging, in which two support-drive units 11 are installed, thus forming the multi-motor drive friction support, containing one, or two, or four support-drive units 11.
