Abstract

Cone crusher are used extensively on mining industry. This crusher are used for breaking rock particles into small fragment called aggregates. By the compressive crushing, it is been proven that it is the most efficient way of reducing size of rock particles. Nevertheless, from the usage of compressive force towards the material being crushed, it also affect the mantle crusher which is the component for the crusher itself. In this report, it will be discussing on the improvement of the mantle crusher reliability by determining on the best material used for the crusher itself. The material used in the cone crusher is nearly the same, but the composition of the material is difference. Each company has their own desired properties that they need to emphasize in marketing purposes. Therefore, in this report it will also shows that how the coating on the mantle crusher itself can prolong it service. Apart from that, the root cause of failure which also leads the mantle crusher problem also will be presented in this report. The failure of the crusher have influence on the productivity of the industry itself. In order to improve its reliability, the critical root cause of failure is needed to be identified so that the replacement can be made on time. The goal on this report to carry out experiment on how the strength of the mantle can be increased as well as its wearing time during operation. This is in order to prevent from increasing downtime error in the industry. Therefore, a coating which is Diamond like Carbon has been use to improve its wear life on the mantle crusher material. In order to investigate the wear rate and improvement in the wear life of mantle crusher, pin on disc and hardness tester experiment has been conducted. For the coated specimen, the result shows increasing in the wear resistance of the material and its hardness compare to the uncoated specimen. This shows a great improvement on the material thus, helping in prolong the service of the mantle crusher.
