Apron feeder a very strong frame holds the driving wheels which have interchangeable hardened steel teeth, the steel belt rollers and the stretching wheels. These are all fitted on hardened and tempered steel pins rotating on large bronze bearings with an ample lubricating box. According to the type of machine, the drive is either carried out by one or two motors, with relating V-belts and planetary gear-boxes. The conveyor track is made of extremely strong steel plates welded to form a highly resistant box; they are connected by chains with amply dimensioned plates, of which the hardened steel pins are housed in manganese steel bushes. The chains are fastened to the outside edge of the plates, ie the outside of the loading hopper, thus avoiding any penetration of material into the articulated parts. In the wider types the plates also rest in the middle on one or more rails in order to support the impact of the falling material. The loading hopper is made of very thick steel plate with linings of non abrasive materials, where necessary. Primary grizzly feeder with pre-screen This machine is suitable to feed primary jaw crushers, selecting the large sizes which require primary crushing, the smaller sizes, and any fines which must be eventually rejected. The machine consists of a very large vibrating body made of thick plate, with inside lining of anti-abrasive plate. The machine is driven by two or four vibrating motors. The machine (which may either be placed on a steel ...
