Loesche developed the 4roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The development was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair of rollers to increase control response availability and flexibility.
products, enabling a high grinding efficiency and stable operation. Figure 3: H However, despite a generally good performance of vertical roller mills used for grinding of cement and related products the vertical roller mill is still inferior to the ball mill in terms of sensitivity to variations of mill feed quality (fineness) and mill feed rate.
HC1700 grinding mill is a better choice for large scale powdermaking projects. It effectively increases the production capacity while reducing the power consumption. Compared to the traditional mill (5R Raymond mill), the capacity of HC1700 grinding mill is about to 4 times higher. HC1700 grinding mill is a kind of large powdermaking ...
