How Does The Hydraulic Grinder Work?

The HHK Hydraulic Grinder uses a machine’s hydraulic system as its power source.

  • Hydraulic oil flows to the hydraulic grinder through the pressure line.
  • The hydraulic grinder converts the hydraulic oil flow and pressure into grinding force.
  • Hydraulic oil is returned to the carrier machine’s hydraulic oil tank via the return line.
