Spacer Sleeve

The pin shaft and spacer sleeve in the hammer mill:

.

Pin shaft: Pin shaft plays a connecting and supporting role in hammer crusher. It hinges the hammer between each row of hanging hammer bodies through a pin hole, allowing the hammer to rotate around the pin axis, thereby achieving material crushing. The design of the pivot allows the hammer to switch working surfaces after wear, extending the service life of the hammer.

Spacer: Spacers are mainly used in hammer crushers to isolate and support various components, preventing direct friction and wear between them. By cleverly isolating adjacent components, the spacer can significantly reduce friction and wear, thereby extending the service life of the equipment and improving work efficiency.

Specific application scenarios and design principles:

Pin shaft: The pin shaft passes through the circumference of the hammer through the pin hole, and the hammer is hinged between each row of hanging hammer bodies. The distance from the center of the pin hole to the axis of rotation is different, which is used to adjust the gap between the hammer and the grate to prevent radial movement of the hanging hammer body and hammer. After the wear of the hammer, the working surface can be replaced to further extend the service life of the equipment.

Spacer: The size of the spacer needs to be carefully checked during installation to ensure that it matches the size of adjacent components perfectly. Keep the surface of the components clean and pay special attention to the installation position and direction of the spacer to avoid performance problems caused by improper installation. The application of spacers is extensive, covering various transmission devices, bearing seats, gearboxes and other components.
