(e) Jaw Crusher Works like an animal's jaw ––nips particles Two crushing surfaces set at a small angle. One surface is fixed and the other is moveable. A common feature -heavy flywheel- storing energy Ore is fed on top Moving jaw advances toward the fixed jaw. The rock particles are nipped between the jaws and broken by impact of the blow.

A jaw crusher usually wears more manganese steel per crushed tonne than a gyratory crusher. Feeding fines into the crusher may increase peak stress loads because of packing ? ie material being compacted as far as it compacts. This is enhanced by moisture, which again is highest in the fines and quite common in underground mines.

The primary crusher is a critical component in the ore processing chain, and its proper selection and operation can greatly impact the efficiency and success of downstream …

"In this case, battery trucks powered by renewable electricity can complete short distances to a crusher, which is moved periodically, with conveyors used for the rest of the journey to the processing plant," describes Russell.

The production of iron ore at Sishen Mine began in June 1953, the ore being crushed and screened in a dry state. In 1961 a crushing and wet-screening plant was erected, and in 1963 the first heavy-medium beneficia-tion plant was commissioned. The production of iron ore for the Sishen-Saldanha Export Project began in 1976 after considerable expan-

When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
