Feeder Control

The flow of material into the crusher can

be controlled to avoid the engine stalling

There are two pressure switches

monitoring at the main crusher drive

pressure

The feeder stops when excessive pressure

is detailed in the crusher drive hydrauliccirciut.

When the pressure drops down to (100

Bar(1450 psi) Standard) the feeder will

start again

This option can be enabled or disabled

from the electrical control panel

Adjusting the Close Side Setting To change the c/s/s first make sure that the “Adjustment” switch is positioned in

the Panel position.

Press the “Jaw Adjustment ON”

Now either use the “Jaw Out” or “Jaw In” buttons to adjust the gap setting

Umbilical Control

To change the gap setting with the

umbilical controller you must remove the

dust cover from the plug and thenconnected the umbilical hand set,

Turn the Adjustment switch to “Remote”

Press “Jaw Adjustment on”

Now use the umbilical hand set to changethe close side setting,

The advantage of using the umbilical for

setting the close side setting is that you

can see what you are doing in relation tothe gap.

Jaw IN When you press jaw in,

The first function is that theclamping cylinders fill up the

annulus side and takes the jawstock metal to metal.

After that the Adjustment wedge

is driven into the crusher.

Then the jaw is allowed to dropback against its own weight as

annulus side of the clamping

cylinder it allowed back to tank .

8/17/2019 Qj340 Manual

Jaw OUT When jaw out is pressed the

clamping cylinders annulus side is

pressurised to bring the jaw

metal to metal and take weightoff of the Adjustment wedge.

The adjustment wedge is thenpulled back out to where it is

required, Then the jaw will fall back under

its own weight against the

adjustment wedge as the annulus

side of the clamping cylinder is

allowed back to tank.
