Adjustment Cylinder

Retention Cylinder Clamping Cylinder

� Fully adjustable hydraulic system for C/S/S adjustment.

� The adjustment wedge is driven in reducing the c/s/s by sliding against the cast cross beam wedge.


Features and Benefits 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

�

� �


Features and Benefits Umbilical Control

� To change the gap setting with the umbilical controller you must remove the dust cover from the plug and then connected the umbilical hand set,

� Turn the Adjustment switch to “Remote”

� Press “Jaw Adjustment on”

� Now use the umbilical hand set to change the 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 to the gap.

Umbilical plug socket


Features and Benefits Jaw IN

� When you press jaw in,

� The first function is that the clamping cylinders fill up the annulus side and takes the jaw stock metal to metal.

� After that the Adjustment wedge is driven into the crusher.

� Then the jaw is allowed to drop back against its own weight as annulus side of the clamping cylinder it allowed back to tank .


Features and Benefits Jaw OUT

� When jaw out is pressed the clamping cylinders annulus side is pressurised to bring the jaw metal to metal and take weight off of the Adjustment wedge.

� The adjustment wedge is then pulled 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.


Features and Benefits Fixed Jaw Plate

� The fixed jaw has a unique concealed wedge & removal cylinder design

� This stops the fixed jaw wedges from becoming distorted during crushing which can happen on other manufactures crusher.


Features and Benefits Extended Cheek Plates

Top check Plate

Bottom cheek plate

� Hardox 400 Cheek plates

� The top cheek plate extends into the crushing feed zone, Reducing blockages across the chamber

� Thus reducing down time and increasing productivity and adds rigidity & Strength to the crushing feed chute


� Unrestricted feed opening & excellent crushing geometry enables crusher to take ‘slabby’ feeds

� “Live” crushing section with replaceable wear plate at the top of the jaw to encourage material into it

Features and Benefits Jaw Crusher
