Flotation safety requirements (1) Replacing the stirrer of mechanical agitating flotation machine must be suspended by wire rope. It is forbidden to use V-belt and hemp rope lifting; when replacing belt or car, it is strictly forbidden to extend the belt and The inside of the pulleys prevents injury; when replacing the gates, pay attention to each other to prevent the gate from slipping and hurting people. (2) It is not allowed to dismantle the safety protection device at will. If it must be removed, it should be restored in time after the work is completed. (3) When using flammable chemicals, the storage and preparation sites of flotation drugs must have fire prevention measures and fire-fighting equipment, and safety signs that prohibit "fireworks". Operators must have knowledge of fire prevention and use of fire-fighting equipment. Sixth, magnetic separation safety requirements (1) should ensure that the magnetic fine and magnetic tail discharge pipe, chute unimpeded, to prevent blockage and cause accidents.
