Hammer breaking patrol essentials: 1, check motor and spindle bearings if there is abnormal sound, whether the temperature is too high. 2, check belt tension is appropriate parameters crushing equipment, stop should check belt for cracks and wear. 3, check if there are channeling the spindle axis phenomenon. 4. shutdown response hammer, liner wear and pin fixed to be checked. Note: 1, the crusher is running prohibited access door open checking or run a job; 2, when the crusher internal checks or work must apply blackout procedures, and more than two. 3, when the crusher failure, to get to the control contact, proper precautionary measures are not free to check the door open. 4, crusher overload of a trip to the equipment and check the internal situation, prohibit forced to boot. 5, found large pieces of hammerhead card, is forbidden to deal with, shall immediately notify the relevant personnel to the scene to deal with and prevent accidents. Hammer crusher is a high-speed rotation and be broken by the impact of mechanical materials. In order to stabilize the movement, normal work, first of all, it must obtain a rotor static balance and dynamic balance. If the center of gravity of the rotor is not its geometric center line crusher equipment, generating static imbalance. If the rotor centerline and the centerline intersection geometry, then generate power imbalances. Both imbalances, will have a huge inertia force and moment of inertia, enabling the machine to produce excessive vibration, making the situation worse by force crushing equipment, reduce the life of the spindle parts, bearings and other parts of the machine frame . Especially cyclical impact load generated crushing equipment types, bearing heat and even damage to the bearings. In addition to the rotor balance problems, as well as machine vibration due to the power imbalance caused by the hammer and the impact hammer blow material factors arising. Therefore, in addition to the manufacture of the rotor to ensure static equilibrium and dynamic balance, it must also be dynamic calculations.
