On the stability of the roll crusher rotor static balance
To roll crusher in the process of assembly, operation and maintenance, it is important to pay special attention to the static balancing of the rotor.Regardless of switching or changing plate hammer on the rotor plate hammer to switch at the same time, lest cause serious vibration and static unbalance of the rotor and bearing heating.New hammer hammer head or replacement on board, should undertake weighing, will be the same or little weight difference weight (0.5 kg) of plate hammer, symmetric configuration installed along the circumference, make whole rotor in static balance state.If there is still a heavy, can take on the rotor temporary increase welding solution to balance the weight.Machine in the process, must pay attention to the observation of main bearing of the rotor temperature rise, normal should not exceed 60 ℃, the highest must not exceed 75 ℃.If the temperature rise over the rules, should stop the engine quickly, take effective measures.Rolling bearing at the ends of the rotor can be used for oil or molybdenum disulfide grease lubrication, each class regularly injected into a small amount of grease (2-3 times).On the roll crusher operation, the dust is bigger, except the crusher parts with good sealing, the workshop should also set the ventilation and dust collecting equipment.If it is double rotor of roller crusher, the two rotor department should be started.A complete set of crushing equipment startup sequence should be: a conveyor, crusher dust collecting equipment feeder;Stop order, to the contrary.
