HCS HYDRAULIC CRUSHING SYSTEM
GI TECHNOLOGY IMPACT CRUSHER
HCS is an electro-hydraulic system that checks and adjusts continuously all the machine components, in particular the
crusher functions, aprons setting and safety. The HCS system provides the power that the crusher needs, it adjust the CSS
with the big cylinders behind the aprons (for a constant output size) and it gives the consent to open the aprons when there
is an un-crushable object inside the crushing chamber. Each cylinder is connected with an hydraulic accumulator and a
pressure switch and in the bottom of the cylinder there is a max valve.
When an un-crushable material is
introduced in the impact chamber,
the hydraulic accumulator absorb
the pressure peak and the apron can
open slightly (the hydraulic
accumulator works as a spring). If
the pressure in the cylinder rise over
the pressure setted with the max
valve pressure, the bottom of the
cylinder will be opened and the
apron will then move to allow the
discharge of the un-crushable piece.
At the same time, the pressure
switch shut down the hydraulic
utilities, except the main conveyor
belt to prevent clogging under the
impact crusher rotor.
