The HPGR product, corresponding to the best condition, is submitted to the standard Bond ball mill grindability test. The Bond ball mill grindability test measures hardness as an index, regardless of the feed size, so it does not give credit for the additional fines. rolls. The priority that HPGR can generate fine products followed by grinding in ball milling, puts a competitive pressure on the application in semi-autogenous (SAG) mills. It is fed from a three-stage crushing system, with HPGR as the third stage. In addition, the possibility of grinding finely at a relatively low energy input and high Ball Mill Ball mills are used for single stage fine grinding, regrinding processes. 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.

HPGR High Pressure Grinding Rolls

HPGR High Pressure Grinding Rolls

 · HPGR wear vs conventional mills. Ball, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis. HPGR and ball mill circuit. This is a highly experimental model. Use at your own risk! The high pressure grinding roll (HPGR) and ball mill circuit can be thought of as a variation on the classical single stage ball mill (SSBM) circuit with the final stage of cone crushing replaced by an HPGR. A typical SAG-HPGR-Ball mill circuit suggested by Patzelt et al. [6] is shown in Figure 9.6, where the pebbles from the SAG mill are crushed in the high-pressure grinding rolls. It is a general observation that SAG mills are helpful for grinding where wide variations in the grindability of ores are experienced.
