Speed is the key to efficiency, but also to safety. Nothing in the rubber industry makes this clearer than a roll mill, where hands and arms are at constant risk.. When a roll mill emergency occurs, every degree counts. The Quick-Stop function of our Hägglunds direct drive systems stops the rollers in down to 3° of rotation, depending on machine.
Home EN; Industries; Mining & Minerals; Grinding; Vertical Roll Mill Drives. Extreme industrial applications require reliable gears units. Designed in close cooperation with mill manufacturers, our vertical roller mill drive series demonstrates long bearing life, high power density and an increased product lifecycle.
As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to maximise productivity and minimise operating costs. The high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited.

Cutting data and tool path programming. Always position the cutter off-centre in relation to the milled surface; With KAPR 90° long edge cutters or end mills, use low radial immersion: max a e = 25% DC and high axial cut: max a p = 100% D e In face milling, use a small depth of cut, a p, and high feed, f z, with round inserts or high feed cutters with small entering angles
