This article will introduce the vertical roller mill wear parts from the function and texture of material. Vertical Roller Mill Grinding Roller. As the main wear part, grinding roller is an entire part and it also includes many small parts, such as grinding roller, roller shell and roller core.
Vertical roller mill Welding Alloys Home 1 / Case Studies 2 / Cement Case Studies 3 / Vertical roller mill Vertical roller mill Cement At the height of the COVID19, we undertook a project to repair a vertical roller mill at Hanson Cement, increasing the lifetime by 400%.
Vertical roller mill has become the first choice for the cement industry, raw material grinding, it is estimated there are more than 600 sets of production. Large vertical mill capacity has reached 600t / h, the transmission power of 5000KW. In the early 1990s, cement grinding mill stand areas has progressed, there are many large mill production.
Introduction The grinding plate is one of the key components of the vertical roller mill, which is mainly composed of resistance ring, lining plate, base, and so on. Its main function is to support the material bed and transmit the force generated by the grinding roll to the reducer at the lower part.
Construction of VRM. The mill consists of the lower casing, uppercasing, table mounted on the vertical planetary gear reducer, and the grinding roller supported by the swing levers .The separator is installed at the upper parts of the mill.
Power taken by the mill The power taken up by the vertical roller mill is given by the following expression N =( I. µ .KT .DR . π.n ) / 60 K W Where, I = rollers µ = friction factor ( for raw materials, for coal) ΚT = specific roller pressure, kN/m2(400 800 for raw and coal) DR = roller diameter, m W ...
