Grinding raw materials needs lots of energy. Tube mills had been used for grinding, but the energy efficiency level was lower. Therefore, the introduction of highly efficient grinding equipment was anticipated. Descriptions The vertical roller mill has high energy efficiency and the installation space is smaller compared with tube mills.
Grinding is carried out as a wet process with water content between 50 – 70% by weight. Rod mills are long cylinders filled with steel rods that grind by compressive forces and abrasion. The length of the cylinder is typically 1.5 to 2.5 times longer than the diameter.
In preparing geopolymer based on red mud (RM), preactivation processes that are generally energy-intensive are employed, including two indispensable steps, namely, calcination and fine grinding. A novel co-grinding preactivation method without calcination was proposed in this study. RM was pretreated by mix grinding with blended coal gangue (CG) (weight ratio of …
