  • Rolling (metalworking) - Wikipedia

    Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock), bar stock, and rails. Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products.

  • Flaking Crush Mills Roll Grinding Precision Roll Grinders

    For flaking mills and crush mills, true roll grinding — which is what we specialize in — is better than in-place roll grinding. In-place (block) grinding is done in bearings on the mill, which does not produce rolls that meet specification. If something is off on one side or anywhere on the roll, the roll can’t possibly attain proper shape, roundness and TIR.
