Repeated impact-abrasion of ore-crushing hammers

1983-5-16  The feed ore consists of approximately 20% very abrasive siliceous material. The crushing rate in the hammer mills is approximately 100 t h~1, and lifetimes range from approximately 30000 t for hammers made from an Ni-Cr-Mn-Mo martensitic cast steel to approximately 75 000 t for Ni-Cr martensitic white cast iron hammers.

Repeated impact-abrasion of ore-crushing hammers

The wear processes which occur on swing hammers used to comminute an abrasive ore were investigated. The performance of martensitic cast steel and white cast iron hammers was studied to assist in the development of valid simulative wear tests by documentation of the mechanisms by which wear takes place in a repeated impact-abrasion application.
