COUNTER FLOW IMPACT ROCK BREAKER

摘要

A rock ring for a rock breaker having an impeller mounted on a vertical axis. The rock ring is formed to retain a quantity of rock in which the flow of material from the impeller creates a rock race. The rock race is formed in a "sling-like" shape by means of spaced rock race control members. Primary rock race control members are placed more closely to the impeller than secondary rock race control members. The method of breaking is primarily by a flow of rock from the impeller table which result in mid-air collisions with a counterflow of rocks which flow from the rock race in the rock ring.
