The Dodge jaw crusher has a variable feed area and a fixed discharge area which leads to choking of the crusher and hence is used only for laboratory purposes and not for heavy duty operations.

From the jaw crusher, the one-half inch material passes through a rotary drum dryer to a system of conveyors, which conveys the material to a surge hopper that feeds the ring roll mill.

Reconstruction involved building an earth ramp and timber retaining wall, welding together pieces of the 5 head stamper battery that were found laying in pieces, bringing a jaw crusher from Mount Garnet and re-erecting the steam boiler.

The INX line was similar to the Q-11 line except that the thawing tunnel has been omitted and a hammer mill and bucket elevator replaces the jaw crusher, rotary dryer, ring roll mill, air classifier, and cyclone separator.

In the Dodge type jaw crushers, the jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it is small enough to escape from the bottom opening.

The iron ore lowered on the inclined plane was forwarded via an 850 metre long electrified ( sometimes helped by a steam locomotive ) which started from the base of the inclined plane and ended at the Reti _ oara's terminus where three electrically driven jaw crushers where installed to crush and sort the iron ore into eight class loading bins where they've loaded the iron ore into the cars of the train from where the iron ore was transported to the ironworks from Govjdia and Hunedoara.
