For over 45 years, North America’s top food producers have relied on Precision Roll Grinders to create better products while saving time and resources.
North America’s top food producers have relied on Precision Roll Grinders for error-free service, emergency assistance and maintenance. For all food processing industries, true roll grinding (which we specialize in) is better than in-place roll grinding. In-place (block) grinding is done on the processing equipment and in the machine bearings, which does not produce rolls that meet specification. If something is off on one side or anywhere on the roll, it can’t possibly attain proper shape, roundness and TIR.
PRG’s true roll grinding results in rolls that meet or exceed OEM specifications — and deliver significant efficiencies and savings:
- Removal of roll corrugations and defects
- Control surface finish to minimize start up time
- Complete hardness mapping of roll face available
- Reestablished end relief for proper operation
- Uniform surface finish using a grinding wheel, not blasted
- Tolerances of ±20 millionths of an inch achieved
- Increased run time of rolls
- Reduced bearing failures
- Energy savings
- Rolls are installed in “ready to run” condition
With PRG, all roll grinding is done at our facilities on the most modern and accurate grinders in the world.
All work is done with a proven process that’s guided by computer data. Bearings and housings are removed to guarantee a perfectly round roll in a temperature-controlled facility. In addition, all rolls are measured using a 24-point SpecCheck™. PRG never blindly assumes bearings are working properly and that the journals are without issues such as chatter or lack of roundness
Our roll grinding and service allows for maintenance to the internal cooling mechanisms, housing and bearings which results in all these benefits:
- Uniform roll cooling
- Increased run time of rolls
- Increased oil extraction yields (crush mills)
- Complete inspection of housing and bearings
- Reduced or eliminated downtime for bearing repair
- Detailed cleaning and painting of housings
We’ve serviced virtually all roll types in the food processing industry, including:
- Flaking mill rolls – corn, soybean and rice
- Forming rolls – snack foods and candy
- Cooling rolls – snack foods and caramel
- Grinding rolls – coffee, chocolate and wheat
- Mill rolls – chocolate
- Press rolls – vegetable oils

Food Crush Roll Savings
SQUEEZING OUT MORE PROFITS FOR THE SOYBEAN OIL INDUSTRY.
73.2 percent of processed soybean oil flakes are out of spec
Which means your flakes are likely to be out of spec as well. And according to a study published by the American Oil Chemist Society*, flakes that fall outside of the 0.010”-0.015” desired thickness will not release all of their oil. This discarded oil represents between $7-16 million in lost revenue every year. Click here to download our one-sheet.
