In-Place (Block Grinding) vs. True Roll Grinding

PRG is a world leader in its ability to produce precise, round rolls. For all food processing industries, true roll grinding 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. 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.
