This Rawlings 4872 Vertical Feed Hog processes debarker waste in Florida at 90 tons per hour with a single 700 HP motor. The vertical wood grinder’s upper case is an example of our clam shell opening that allows easy access to full rotor for ease of maintenance.

Unique Features of Rawlings Wood Hogs
Designed with Rock Crusher Technology
Because they are 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 Safety Swing away Anvil triggers the shear pin to shear allowing the anvil and grate to open if excessive shock loads or ungrindables are encountered immediately turning off the power to the hog.
The anvil pivots at the top of the housing with the shear pins at the bottom next to the impact of the striker bars. 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.
Rocwear™ Striker Plates and Striker Tips
Our Patented Rocwear™ striker plates and striker tips. These 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.
