Rawlings Horizontal Wood Waste Grinder

Rawlings 460 Horizontal Feed Hog processing wood waste with twin 300 Horsepower motors for a industrial Mulch bagging operation. This system is complete with a receiving conveyor, belt in-feed and vibratory out-feed conveyor, metal detector, work platform and Rawlings Horizontal grinder. Each unit is equipped with the Rawlings Super Hi-Inertia™ Solid Steel Rotor. With the increased inertia of the solid steel rotor our machine runs at lower RPM’S than our competitors resulting in overall savings of electricity and maintenance costs.

Industries &

  • Designed with rock crusher technology the machines are extremely tolerant of contaminants, rocks and metal without catastrophic maintenance costs if metal enters the grinding chamber. The Rawlings HZX is protected by an Anvil Safety Shear Swing Away Feature , that allows metal and other damaging objects to drop through on to the out-feed conveyor. When the Pins are sheared, a protection circuit shuts down the Hog and conveyor.  The anvil shear pins are mounted in removable brackets ensuring quick turnaround time to remove large sections of tramp metal and have the hog up and running again.
  • Super Hi-Inertia™ Rotor Each machine is equipped with the Rawlings Super Hi-Inertia™ Solid Steel Rotor. With the increased inertia of the solid steel sections our machine provides the crushing and shearing power needed to handle really tough applications like green waste, cypress, redwood, cedar and black spruce without continuous jam ups. The Rawlings machine runs at lower RPM’S than our competitor’s machines and half the speed of conventional hammer mills resulting in overall savings of electricity and maintenance costs. The cam profile of the Rawlings rotor prevent feed surges by keeping material closer to the cutting edge of the bits. This translates to better productivity as the in-feed conveyor is stalled less frequently and less down time as the increased energy reduces the number of motor drive stalls.
  • Our Patented Rocwear™ striker plates and striker tips are easily replaceable when worn and provide tremendous wear life with superior grinding performance. The Rocwear system consists of a striker base which gets bolted onto the rotor and a rotatable striker tip that gets bolted to the striker. The strikers serve the purpose of protecting the rotor from wear and shock as they are designed to absorb impact loads. It has been shown that with this setup, the time to change each bit takes only about 2.5 minutes and requires only one maintenance personnel. Not only does the Rocwear system provide an easier way to maintain the rotor, they have also been proven to last much longer than standard T-1strikers.
  • Heavy Duty grate assembly with rotatable grate liners available in several patterns to produce a quality consistent end product .
  • Auto Lubrication System
  • Bearing Temperature Control
