What are the conditions for the replacement of jaw crusher parts?

The jaw crusher is the most widely used crushing machine, with its simple structure, easy operation, large processing capacity, and durability, and is favored by all industries. Here is a detailed description of the conditions for the replacement of jaw crusher parts.

Here is the content list:

• Liner plate replacement conditions

• Jawbreaker shaft, eccentric shaft, and shaft tile replacement conditions

Liner plate replacement conditions

The fixed jaw liner, the moving jaw liner, and the two side liners of a jaw crusher are the most easily worn jaw crusher parts. Severe wear causes the product size to become larger. For initial wear, the tooth plate can be turned around and used, or the upper and lower plates can be turned around and used. The jaws are worn, mostly in the middle and lower part, and need to be replaced with new liners when 3/5 of the tooth height has been worn off. When 2/5 of the liner plate is worn off on both sides, new jaw crusher parts are also needed.

Jawbreaker shaft, eccentric shaft, and shaft tile replacement conditions

If the shaft wear is little, just to repair its geometry, it can be turned on the lathe to make the journal reach the correct geometry, and then reduce the bearing inner diameter accordingly. However, after several such treatments, if the journal size is reduced by 5% compared to the original, no further turning is allowed and the jaws should be replaced with new jaw crusher parts. The jaw crusher is working under impact load and the balsa lining on the shaft tile, which works for about two years, will need to be recast for jaw crusher parts beyond that period. If the eccentric shaft and the shaft tile, the mandrel, and the shaft tile are worn and the top clearance is greater than 1.5 times the original assembly clearance, they need to be gasketed and adjusted or replaced; if the oil groove is worn by 1.5 mm, the oil groove should be reopened and the jaw crusher parts adjusted. The clearance between the connecting rod headcover and the eccentric shaft, when worn to a level greater than 1.5 times the assembly clearance, also needs to be gasketed and adjusted or replaced with a new jaw crusher part. Jaw crusher parts should be recast when there is deep spalling or large abrasions in the balsa on the shaft tiles. The quality of the processed shaft tile has the following requirements: the color of the pasteurized alloy surface should be uniform, light-free, and silver-white; the pasteurized alloy surface layer should not have ash slag, cracks, sand eyes, shrinkage holes, etc. and the phenomenon of shelling.

The above is about the conditions of jaw crusher parts replacement. Let you know this knowledge because from the sales situation of Hyton Group Mechnical Equipment Co., every year, the sales volume of jaw crushers alone is very good, which objectively reflects the huge demand for jaw crushers in the market. Readers can have some understanding of the replacement conditions of jawbreaker parts through this article so that they can save some cost for the enterprises using jaw crushers and improve the efficiency of enterprises.
