All of our vertical mills come with NST 30 or 40 spindles for an extra rigid transfer of power from the inverter driven (most are Yasakawa®) head. Meaning no pulleys and gear drives but only offering solid power to the cutter for heavier cuts and longer tooling life. The inverter drives also means that each model is variable speed.
Siemens has recently launched two new compact solutions for the optimum and energy-efficient driving of vertical roller mills (VRM) for the cement industry. The Flender MultipleDrive offers variable-speed drive and the EMPP drive provides a compact motor-in-gear solution for modern, high-performance milling.
IDEAL Eddy Current Variable Speed Drives use constant speed electric motors and a DC magnetic field to reduce speed and generate incredible amounts of torque effectively. Our drives are intended to move high-inertia loads that frequently start and stop more efficiently than variable frequency drives (VFDs) are capable of. This incredible efficiency greatly reduces …
