Speci󰘰cation and Plant Information
Hopper and Feeder
1. Hopper with hydraulic folding sides and end
plates.
2. Spring mounted vibrating grille feeder, driven by
a heavy duty vibrating mechanical unit with twin
eccentric rotating shafts.
3. Drive is by hydraulic motor with variable speed
control.
4. Feeder grille is a double section of welded
tapered 󰘰nger type bars, fabricated in abrasion
resistant steel.
Plant Components
Under screen
5. A rubber blanking mat will be 󰘰tted where the
plant does not have the dirt conveyor 󰘰tted.
6. The under screen has a removable mesh, used
in conjunction with the optional dirt conveyor. If
the material is able to be screened, it allows the
extraction of smaller 󰘰nes onto the dirt conveyor
with the coarser material discharging onto the
product conveyor.
7. By removing the mesh entirely all the 󰘰nes are
directed to the dirt conveyor.
Crusher
9. Single toggle jaw crusher with feed gape of
820mm (32in) and width of 1420mm (56in),
operated by eccentric shaft driven by vee belts
and pulleys from engine.
10.The crusher has setting adjustment by hydraulic
operation of wedges.
Pre-Screen
8. The pre-screen is prior to crushing, this
removes the 󰘰ne material that does not need to
be crushed, therefore increasing e󰘲eciency of
the crusher. The pre-screen 󰘰nes drops to the
dirt conveyor therefore bypassing the crusher
unit.
