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.”

Hi Inertia Solid Steel Rotor

Super Hi Inertia Rotors

Meet the highest crushing impact rotor in the industry……… period.

Rawlings Wood Hog Rotor

The Rawlings rotor is designed to maximize inertia while minimizing its weight.  With the increase of inertia our machine runs at lower RPM’S than our competitors 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.

The Rawlings Super Hi-Inertia Hog provides the crushing and shearing power needed to handle really tough jobs like green waste, cypress, redwood, cedar, black spruce, poplar and a wide range of other stringy and fibrous materials.

Extremely tolerant of Contaminants, Rocks, Metal without catastrophic maintenance costs if metal enters the grinding chamber.

Hammer hogs run at higher RPMs than that of a solid rotary hog.  In general hammer hogs contain a plurality of pivoted hammers on the outer rotor dimension. The hammers pulverize the material against an anvil. The rotor is light and the hammers are heavy. The rotor tends to be difficult to start because the pivoted hammers hang towards the bottom of the machine. Bearing wear is high and maintenance is excessive.  The hammer hog is also unsuitable to handle contaminants without extensive catastrophic damage once they enter the grinding chamber.

“Customer Testimonial on Rotor Retrofit of a Universe Hog”

I wanted to share with you a few comments about our recent Rotor Retro-fit to the Rawlings Hi-Inertia Rotor completed in January of this year. Before the change we were having to turn the strikers or resurface every two weeks and completely change out every six weeks. It is now 17 weeks using Rocwear strikers and bits and we have yet to change any parts. That is operating over 85 hours a week or 1445 hours. Friday is maintenance day and it seemed like we were spending 8 hours on maintenance. Now, its open it up, inspect, and close it back up. In a test done just before the change, we processed a log about 10″ diameter x 8′ long. It took about 17 seconds to process a mix including unusable sticks up to 20 x 2 ½. After the conversion we processed the same size log through which cleared in 10 seconds with a consistent quality 3 inch minus we’ve maintained everyday since.In the final analysis we successfully:

  • Reduced maintenance costs (parts & labor) over 80%
  • Satisfied our customers with a consistent 3 minus hog fuel.
  • Eliminated conveying problems.
  • Reduced or eliminated unnecessary shutdowns.
“Thank you for your assistance in helping the conversion run smoothly. We are very pleased with your product.”   Millar Western Boyle Alberta

Rocwear Solutions

Rocwear Solutions wear parts for wood hogs

In the continuing effort to provide innovative products Rawlings Manufacturing Inc. consistently performs extensive research to improve the longevity of our spare parts to our customers .

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-1 strikers. They are cast from a proprietary alloy with Rockwell C hardness between 45 to 50. T-1 plate has a hardness of less than 30 Rocwell C.  With less down time and easier maintenance customers have applauded both the Super-Hi Inertia rotor as well as the Rocwear striker system.

Suitable for the following machines Rawlings | Solid Rotary Hogs |Universe Clark Falcon | Grizzly | M-K

  • Fast Maintenance
  • Cuts 30 minutes job down to 2 minutes
  • Tough long wearing RocWear with rotatable bits
  • Z-197 bits easily rotate to a second wear surface
  • No more costly hard surfacing
  • Rawlings Rotor Retrofits-Retrofit your hog with a Super Hi-Inertia rotor
  • Custom hammer mill screens and wear parts for competitors machines
  • Bolt in rotatable hog screens
  • 24/7 customer service

“Sometime in early 2006, we changed to the new round style Hi-inertia rotor with Rawlings RocWear system. The only parts we have to change out are the Z-197 striker bits and fasteners. We used to go about 2 to 3 months or so before having to rotate the bits and the same to changing them out. To date, we seem to be getting about 2 to 3 times the life with the new style bits. Compare this to other hogs we have had were maintained at least weekly and you will see there is no comparison at all.”

Biomass Power

Biomass Co-generation

 

Eversource Biomass Plant

 

Read Article

Rawlings wood grinders are currently operating at several of the largest biomass power plants in the United States. Since 1976, we have focused on manufacturing grinding equipment that turns low grade materials like wood waste into valuable fiber commodities like wood fuels. The United States is currently the largest producer of electricity from biomass having more than half of the world’s installed capacity. Biomass represents 1.5% of the total electricity supply compared to 0.1% for wind and solar combined. More than 7800 MW of power is produced in biomass power plants installed at more than 350 locations in the U.S., which represent about 1% of the total electricity generation capacity. According to the International Energy Agency, approximately 11% of the energy is derived from biomass throughout the world.

Fossil fuel and nuclear energy are not going anywhere any time soon; however, with growing support in the United States and favorable statewide green-energy legislation, the future for biomass is bright. When efficiently collected and processed, biomass is affordable and reliable.

As proven leader in size reduction technology, Rawlings builds custom wood recovery systems meet your specific processing needs and budget. Each system can be designed with work platform decks, choice of belt, chain,vibrating in-feed and out-feed conveyors. Metal or magnet protection, product screening and separation, all customizable for your specific operation. Stationary, Portable and skid mount models available.
