PRESSURE INTENSIFIER OPERATION
NPK’s exclusive pressure intensifier system is used in NPK M35 Material Processors to
boost cylinder pressure to increase the jaw closing forces. When the intensifier is
working properly, a rapid clicking sound will be heard, indicating that the pressure
intensifier is being actuated as the jaws begin to close against resistance. As the jaws
grasp tighter onto the material, the clicking will begin to slow down. This slowing will
continue until the material is either cut/crushed or the M35 Material Processor meets full
resistance. At full resistance, the clicking will slow dramatically or sometimes stop
completely.
PRESSURE INTENSIFIER (BOOSTER)
The control valve (bs10) and booster assembly (bs27) make up the pressure intensifier
assembly.
RAPID CONTINUOUS CLICKING IS HEARD AND THE
MATERIAL IS NOT BEING CRUSHED/SHEARED AS
EXPECTED
This indicates that the problem is not a relief setting, but it is in the intensifier or the
cylinder of the M35 Material Processor. This requires further investigation by a
mechanic/technician, see
“INTENSIFIER CHECKS”
