When the crusher is crushing materials, wear often occurs between the inner hole of the pulley and the drive shaft. In order to reduce this wear, we need to replace the copper sleeve frequently. The following is a brief introduction to the replacement of the copper sleeve of the crusher:

Before installation, the copper sleeve needs to be chamfered inside and outside, and placed in the position shown. Place a hydraulic jack between the gland and the top cover, and then adjust the screw to make the jack act on the gland; fix the top cover, start the jack, Make the jack react evenly to the copper sleeve through the gland, and then the copper sleeve can be slowly pressed into the inner hole of the pulley.

When removing the copper sleeve from the copper parts of the crusher, turn the pulley over and adjust the screw rod at the same time, and use the same method to eject the copper sleeve from the inner hole of the pulley.

If you are a customer of copper products such as crusher copper sleeves, or have any needs in the use of copper sleeves and other products, you can contact us. We specialize in designing and producing crusher copper sleeves with rich expertise.

The mining crusher mainly crushes various types of stones. The crusher is mainly composed of a frame, a drive shaft, an eccentric sleeve, a spherical bearing, a crushing cone, an adjustment device, an adjustment sleeve, a spring, and a discharge port.

The main frame of the crusher is composed of an upper frame body and a lower frame body. The two are connected by hydraulic cylinders. There are wear-resistant liners and protective covers inside: the upper frame body is a welded part, and the upper mouth is welded with a wear-resistant copper plate. Integral steel castings. Among them, copper frame bushings and wear-resistant copper plates are very important parts.

Crushers include jaw crushers, impact crushers, impact crushers, etc. These common crushers are almost the same. The most important thing about a crusher is the quality of the wear parts.

Whether it is a fine crusher, a sand making machine or a crusher, the wear parts are the equipment that wears the fastest and is replaced the most frequently. Therefore, the copper sleeve of the crusher has higher requirements for wear resistance.

In actual production, the main wear and tear of the crusher's copper sleeve are the wear and damage of the main shaft and the cone bushing, the wear and damage of the eccentric shaft sleeve and the straight bush, the wear and damage of the thrust plate and the gear, the frame and the Spherical bearings wear and damage these aspects.

The copper bushing of the crusher produced by our factory is a lead bronze bearing which uses the gushing oil of the oil groove as the lubrication. Lead bronze has high fatigue strength, thermal conductivity and wear resistance, and will not crack under the working conditions of impact load.

The copper sleeve of the crusher has high bearing pressure and can be used in heavy-duty occasions. At present, the copper sleeve of the crusher is mainly used in the stressed joint parts of the crusher and the large gear box.
