levels of vibration are indications of condition except where structural resonances (e.g.: bearing housings, or motor bases) amplify vibrations at certain frequencies (usually integer multiples of shaft speed). Dynamic response at vibration test points can be measured on new installations to assist in establishing standards for absolute vibrations.
grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.
