John wrote (Mar 2007): " The workman in the bottom R.H.corner gives a good scale factor to this shot..... Basically the crushers had eccentric shafts which closed and opened a tapered slot ..... thus crushing the inserted stone.
Stone was delivered on small gauge trucks (drams) then manhandled into the crusher.The gravel produced dropped through, then was raised up in the central vertical conveyor and dropped into the storage chamber which was probably fitted with a grading drum at the bottom .This consisted of a rotating cylinder set at a downwards angle .The various stone sizes falling through different sized holes as they pass through.
Interesting to note the minimal use of high energy materials in the construction of this plant, also the complete lack of safety guards".
