    Abstract The effect of using conventional and high pressure grinding rolls (HPGR) crushing on the ball mill grinding of an iron ore was assessed to determine how these different comminution processes affect the ball mill grinding kinetic. For this purpose, the sample was obtained from the Jalalabad Iron Ore Mine and crushed by conventional.

    Robert McIvor (Optimization of High Pressure Grinding Rolls) In our project, we’re going to extend the application of high-pressure grinding into fine grinding, that is, to replace ball mills. Ball mills are still the workhorse of the industry when it comes to producing the final fine product ahead of separation processes like flotation.

    Wears are most important in grinding compared to crushing. Because as far we go to finer sizes wears increase due to collosion requirment for further size reduction. Besides, the grinding media generates extra wears production. The demand for high pressure grinding rolls (HPGRs) increases recently, as they respond to features requirements.

    CRUSHING. Resources Unity proudly distributes crushers of global brand. . Prime Primary Gyratory Crushers offer a range of crusher sizes to suit the most demanding of applications in some of the world’s largest mining projects. With feed sizes up to 1200mm and capacities of 8000TPH. Combined with high speed (600rpm) and a range of eccentric.

    After the crushing process a ball mill is one of the most important equipment used for secondary grinding. Size reduction is carried out through Impact of the balls, this is the main working principle of a Ball mill. The cost of installation and the consumed power in a ball mill is much lower which makes it very economical in a grinding circuit.
