The crusher rotor is the core of the hammer crusher, and its structural forms can be divided into alignment type and cross-arranged type. The alignment type refers to the arrangement of the crusher hammers in mutually aligned manner. According to the size of the crusher rotor, the circumference is divided into 4 to 6 rows, and each row has different crusher hammers from 7 to 11. The cross-arrangement type means that the crusher hammers are arranged in a mutually intersecting manner. According to the size of the crusher rotor, the circumference is divided into 4 to 6 rows, and each row has different crusher hammers from 6 to 8.
 

The hammer crusher impacts , grinds and crushes the limestone through the high-speed rotating hammer head. Due to the impact and friction of the equipment during the long-term operation, the rotor components are inevitably worn, deformed and damaged, and the normal working ability is lost. If the working state of the rotor is not analyzed to predict its service life, and carry out the planned maintenance and overhaul, in the event of an emergency, the company will cause serious losses in the whole line. Therefore, the maintenance of the hammer crusher rotor is necessary.
 

Suggestions for routine maintenance of the hammer crusher:
 

1. Before using the hammer crusher, check whether the connecting bolt is loose, whether there is any debris in the crushing chamber inside the machine, whether the lubricating oil of each rotating bearing and other rotating parts is sufficient, whether the transmission device and the motor have belt breakage and layer formation phenomenon, whether the junction box and grounding device of the motor are firmly connected, ensure that the protective device of the transmission mechanism is intact. Before starting work, that all the components of the machine are in good condition must be confirmed.
 

2. When the hammer crusher is working, if it is suddenly stopped during normal operation, the machine equipment must not be forcibly started before the cause is found, during the operation of the machine, if the machine generates abnormal vibration or abnormal knocking sound inside, stop the machine for inspection and discharge, and do not directly start the inspection to avoid accidents.
 

3. In the daily use of the hammer crusher, the machine should be maintained on time. Always check the tightening condition of the bolt connection points of each component, and tighten the loose bolts in time, after each work, the sieve bars in the working chamber should be cleaned up and discharge excess materials and blockages, always check the wear level of the wearing parts of the machine, and replace the parts that are seriously worn out in time, ensure uniform feeding, not too much or too little, to prevent the machine from overloading, also the lubricating oil must be clean and the bearings should be cleaned regularly to ensure the flexibility of the bearings.
