Effects of compression and sliding on the wear and energy …
Previously, also Lindqvist and Evertsson [10] have used force cells to assess the mechanical forces in jaw crusher wear tests. The jaw crusher they used was choke fed with quartzite of size 8–11 mm, resulting in compressive force peaks of 6–13 kN per crushing cycle. The measured average friction coefficient was about 0.3.

Abrasive wear properties of tool steel matrix
Abrasion may occur by microploughing, microcutting, microfatigue and microcracking [1]. In the simplest case, only one type of wear mechanisms is present. However, usually several wear mechanisms occur at the same time. For example, in the compressive mineral crusher, abrasion, impact and compressive type of wear are all …

Budinski (1991) quantitatively compared the abrasive wear resistance of Grade 2 CP Ti and Ti-6Al-4 V with a portfolio of other metallic materials using the ASTM G65 dry sand–rubber wheel abrasion test. The results, given in Table 3.1, clearly demonstrate that both grades of titanium have poor abrasion resistance.The abrasive wear rates of these two titanium …

Selecting the right crusher for your operations
The specialised design uses a shelf system with an abrasion-resistant wear bar that allows crushed material to build up and act as a wear liner. The result is zero maintenance, which translates into considerable savings in labour and wear parts. Clearly, there is no shortage of options to consider when selecting a mobile crusher.

Jaw Plate Failure and Life
Without this the crusher has to rely on energy and friction to crush the rock. Compaction will also impose increased loads to the crusher as much as five times the normal crushing force. To the opposite,feed material that is too large also affects wear life. A jaw crusher in most applications is a 6 to 1 ratio of feed reduction.
