are secondary crushing
machines. They are made of fabricated steel structure with alloy
steel shaft and gears.
adjustment of the opening to vary the size of product is achieved by
hydraulic ram provided for turning the upper body.
Efficient lubrication reduces wear and tear and also helps to
dissipate heat generated. It is provided with Mechanical Seal With
Compressed Air System consisting of good quality mechanical seals
which prevent ingress of dust particles into the main bowl bearings
and at the same time a steady flow of compressed air serves to blow
away the particles from the bearing area. This has the advantage of
not having problems created by water entering the lubricating
system in water seal arrangements and resulting in bearing and drive
