Abstract:

The app lication o fHP cone crushers in the designing and transformation o f crush ing in steel and non-ferrous metallurgy concentrator is described. The practice show ed that the 0~ 5 mm powder content in the product of HP high efficiency cone crusher was not ably higgher than that of old type spring cone crusher. "more crushing and less grinding"was thus realized with the least investment and ballmill efficiency and through-put were raised without changing the crushing technology, thus achieving good economic benefit.

Key words: HP core crusher, More crushing and less grinding, Fine fraction content
