In the case of Slag grinding, the acceptance of roller press in finish grinding is well recognised. It offers the distinct advantage of saving of about 67 Kwh/t as compared to Vertical Roller Mill at 4200 Blaine. KHD has sold 27 Sag Grinding Circuits and maintains about 70 % market share in slag grinding in India.
The more roll pairs the mill has, the greater the size reduction it can achieve. For instance, reducing salt feedstock to coarse road salt requires a roller mill with one roll pair, while reducing the material to table salt requires a mill with two or three roll pairs. More about the feeding device. The feeding device is integral to the ...
