What about shock and blockage in hammer crusher?
1, hammer broken, the rotor imbalance;2. The pin becomes bent and broken;3, replace the hammer head or because of cone wear, make the rotor static balance is not required;4, triangle or disc cracks;5, anchor bolts loose.
During the operation of the hammer crusher, the vibration of the machine is one of the common faults. There are many reasons for the machine vibration, and can be broadly divided into the following:
The shock of crusher equipment can be said to be very normal, but too much vibration will have an impact on the production of equipment, so we will minimize the shock of the equipment. For hammer crusher, the use of belt drive will appear vibration equipment, we will tighten the anchor bolts, make the device firmly fixed on the basis, and pave the way for the rubber pad and other insulation materials to reduce equipment noise between the base and the equipment. In order to change this situation produces vibration, we use a povee motor is directly connected with the way, let the motor and the hammer crusher are connected as a whole, because the vibration caused by the decrease of belt transmission, reduces the noise generated by equipment. Hammer crusher has another reason for the vibration of the rotor imbalance, rotor imbalance is due to the crusher hammer quality caused by the different methods, therefore, to change this situation is to reduce the error of the crusher hammer, let the whole rotor more balanced, this is the most fundamental solution. Hammer crusher is not blocked, but if the stone humidity input is too high, or the number of stone too much, fast grain is too high, it will cause the hammer crusher discharge port plug, under such circumstances, we need to stop equipment for cleaning and dredging, when the humidity and stone note the stone size should be again when input, input and maintain stone stability, not the unsteadiness. These are the most basic, can be seen on the site of one of Rui Pu
In view of the cause of the machine vibration of hammer crusher, the following methods can be used:Replace the hammer; replacement pin; remove the hammer, hammer to choose according to the weight, total weight of each hammer shaft hammer and hammer shaft relative to the total weight of the hammer is equal to the static balance to achieve the requirements; welding repair or replacement; fastening bolt.
