The correct installation of hammers plays a crucial role in the assembly and maintenance process of crusher equipment. As a key component of the crusher, the quality of hammer installation not only affects the crushing efficiency of the equipment but also directly impacts its service life. However, in actual operation, some common installation misconceptions are often overlooked, which in turn negatively affects the equipment's performance. This article will analyze these misconceptions in depth and provide corresponding solutions.

　　I. Ignoring the Balance of Hammer Installation

　　When installing hammers, if all hammers are not replaced simultaneously, or if hammers with similar weights are not symmetrically distributed along the circumference, it may lead to static imbalance of the rotor. This imbalance will cause violent vibrations during equipment operation, and even lead to problems such as bearing overheating.

　　Countermeasures: Before installing the hammers, all hammers should be accurately weighed, and hammers with similar weights should be evenly distributed along the circumference. If an imbalance is found in the rotor, it can be adjusted by adding balance weights at appropriate positions.

　　II. Tight Hammer Installation Leading to Poor Operation

　　During installation, if the hammers are installed too tightly, they may not be able to swing freely during operation, thus affecting the crushing effect of the equipment. This situation is often accompanied by increased equipment vibration and performance degradation.

　　Countermeasures: After installation, the flexibility of the hammers should be checked. If the hammers are found to be installed too tightly, their installation position should be adjusted or appropriate hammers should be replaced to ensure that the hammers can swing freely during operation.

　　III. Insufficient Rotor Lubrication and Sealing Leading to Failures

　　The rotor, as the core component of the crusher, its lubrication and sealing status are crucial to the equipment's performance. Ignoring the lubrication and sealing of the rotor will lead to accelerated bearing wear, dust pollution, and other problems, thus affecting the stability and service life of the equipment.

　　Countermeasures: During installation, ensure that the bearings at both ends of the rotor are adequately lubricated, and regularly inject an appropriate amount of grease. At the same time, carefully check the sealing status of each part of the crusher to ensure good sealing to reduce dust pollution. For parts with poor sealing, repair or replacement should be carried out in time.

　　In summary, the common misconceptions in the installation of crusher hammers mainly include ignoring balance, installing hammers too tightly, and insufficient rotor lubrication and sealing. To avoid the negative impact of these misconceptions on equipment performance, operators should have rich experience and professional knowledge, and strictly follow the installation procedures. At the same time, after the equipment is installed, a comprehensive inspection and debugging should be carried out to ensure that the equipment can run smoothly and perform at its best.
