PROCESSOR BOOSTER & CYLINDER
INTRODUCTION
The hydraulic cylinders used on the NPK Material Processor are equipped with
hydraulic boosters. To close the jaws of the processor, hydraulic oil from the carrier is
directed to the base end of the cylinders, which extends the cylinder rods. Under no
load, no boost is applied and this results in a rapid cycle time as compared to large,
non-boosted cylinders.
When a load
(material to be crushed or sheared)
is encountered, the oil is directed into
the booster sections of the cylinders, which intensifies the pressure well beyond the
system operating pressure of the excavator. The compact NPK Boosted Cylinder
System provides a working force equal to a far larger non-boosted cylinder, which is
working at excavator system pressure. Because the NPK boosted cylinder is smaller, it
requires less oil for full stroke as compared to a large diameter cylinder. This reduces
cycle time for the NPK Material Processor. To open the jaws of the NPK Material
Processor, oil is directed to the rod end of the cylinder. This retracts the rod and pulls
the jaw open. No boost is provided in the jaw opening mode.
