Shenyang Crusher Installation Method

A proper crusher installation method can effectively control vibration transmission, reduce noise, and effectively extend the service life of electrical components and power units. A proper installation method is crucial to the crusher's service life and performance.

The following briefly analyzes several crusher installation methods.

1. Rigid Connection

The crusher mainframe and frame are connected by bolts and nuts, without any buffering or vibration damping devices between the crusher mainframe and frame. Because the bolts have a high elastic modulus and low deformation, this method is considered a rigid connection.

Crushers are subject to significant impact during operation. The occurrence of bolt loosening is related to the mechanical equipment's structural design. Its ability to absorb or buffer dynamic loads directly determines its performance. If the structural design cannot be optimized, adding steel spacers can improve the bolts' impact resistance. This solution increases the total elastic deformation by lengthening the bolts. This deformation offsets the load impact, thereby ensuring preload and preventing bolt loosening.

2. Rubber Vibration Damper Connection

Crushers typically use rubber vibration dampers, consisting of two upper and lower steel plates glued together with a rubber block in the middle. The steel plates have threaded holes for bolting, and the rubber block provides vibration and energy absorption. The crusher mainframe is bolted to the upper steel plate of the vibration damper, and the frame is bolted to the lower steel plate.

3. Rubber Vibration Damper + Hydraulic Cylinder Leveling

Mobile crushing station frames are typically welded components, subject to deformation due to welding stress. Maintaining the geometric and positional tolerances of the mounting surface is difficult, even with the aid of welding fixtures. Adding rubber vibration dampers cannot address the assembly stresses caused by structural deviations. To meet actual usage requirements, technical requirements have been improved, and process control of the mounting location has been strengthened.
