In general, the reducer of mine powder ball press can continue to be used in the case of moderate wear or abrasive wear. Moderate wear generally occurs in the place where the metal contacts and the root of the reducer. The cause may be lubricant contamination. This is unavoidable because sometimes due to certain limitations such as gear speed, lubricant viscosity and temperature. Abrasive wear is the characteristic of the abrasive wear of the reducer on the mineral powder ball press machine. This can show the radial scratches formed in the grooves or because of the lubricating particles of the general system of the reducer. The reducer is an indispensable equipment in the mine powder briquette forming machine. Through the link of the reducer, the motor and the device can be completely integrated together, and the motor rotates rapidly, which is slowly lowered by the reducer. It plays an important role in protecting equipment.
