Welcome to Rawlings Waste Wood Recovery Systems

The Future of Wood Waste Recovery

The original rotary hog was invented and developed by Rawlings Manufacturing in 1977. Since then our family owned company has manufactured and marketed several series of product lines. The wood waste recovery systems are available in stationary, portable and skid mounted systems; both vertical and horizontal models are available. Rawlings Wood hogs come in all shapes and sizes, from simple stand-alone vertical hogs™ for saw mills, pulp, paper, power & pellet plants to complete custom horizontal hog systems that can process material of any length such as logs, forest debris, and urban waste. Our equipment is built to last with the lowest operating costs per ton of material processed. We are dedicated to advancing this technology and to providing the very best support to our customers.

Super Hi Inertia Solid Rotary Wood Hog

Rawlings patented Super Hi-Inertia Hogs are designed to run 24/7 365 days a year. Our rotor is equipped with the highest mass moment of inertia in the industry. This machine provides the crushing and shearing power needed to handle really tough jobs like green waste, cypress, redwood, cedar, poplar, and a wide range of other stringy and fibrous materials. The PXZ can get you back on track with your most difficult and demanding waste conversion problems. The Rawlings Super-Hi Inertia Rotor was designed to maximize inertia while minimizing its weight. The cam profile of the patented Rawlings Super Hi-Inertia rotor also prevents feed surges by keeping material closer to the cutting edge of the bits. Our grinders are equipped with Rotatable Rocwear Striker System. This design provides the customer with two cutting edges per bit. With less down time and easier maintenance, customers have applauded both the Super-Hi Inertia rotor as well as the Rocwear striker system.

Compare this to other hogs we have had were maintained at least weekly and you will see there is no comparison at all. This Rawlings machine is easier to work on, get into, and inspect than any other hog we have had. I would have to say that overall, this is a very fine machine. I have only found one drawback with this machine. You sometimes forget to check it out regularly because you never have any problems with it.”
