Abstract

The invention discloses a rough grinding machine. The rough grinding machine comprises a machine body, a driving mechanism as well as a rotational support, a grinding wheel device, a grinding roller device and a loading device which are arranged on the machine body, wherein the rotational support comprises a fixed ring fixedly arranged on the machine body, a revolving ring arranged to be coaxial with the fixed ring and a rolling body arranged between the fixed ring and revolving ring, the driving mechanism is used for driving the grinding wheel device to revolve through the revolving ring, theloading device can be used for driving the grinding roller device to slide on the machine body to realize switchover between a loading state and an overhauling state, in the loading state, the grinding roller device can be pressed on the grinding wheel device through materials, and in the overhauling state, the grinding roller device and the grinding wheel device are kept away from each other. The rough grinding machine has the advantages of simple structure, high rough grinding efficiency and convenient maintenance.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a coarse grinder. Background technique [0002] At present, the equipment used for grinding mine materials is mainly various roller mills, while the existing vertical mills are inefficient in the occasions where the finished product particles are relatively coarse. Among them, various roller mills are generally powered by a motor, and the transmission part drives the grinding disc to rotate, and the material is ground through the cooperation of the grinding disc and the grinding roller. The transmission between the transmission part and the grinding disc is generally carried out through the main shaft assembly, and the positioning support is completed by the rolling bearing in the main shaft assembly, and the grinding disc can be rotated under the drive of the motor. However, since the grinding disc and the transmission parts are separately arranged at the two ends of the main sh...
