For instance, if the mill overloads and requires grindout every hour at 500 tph, but will run steadily without issue at 450 tph, then the required adjustments should be relatively minor. Even if you end up at a slightly lower "peak" operating rate, the benefits of steadystate operation ...

WhatsApp: +86 18203695377Larger ball and SAG mills, with higher installed power ratings relative to the mill diameter, offer higher efficiency and throughput, roundtheclock reliability and the opportunity to mine in remote areas. ... especially when you consider that some modern mines may have as many as six 1525 MW GMDs running in parallel.
WhatsApp: +86 18203695377If the SAG mill is not intended to be the ratelimiting step in a process plant, then it is best to adjust the SAG load (and power) to hold a constant tonnage to satisfy another constraint elsewhere. Underground mines are an example: the hoisting capacity of the mine shaft is the ratelimiting step in the process, and the SAG mill must adapt to ...
WhatsApp: +86 18203695377material from the SAG mill is mathematically bypassed to the finished product, and is not used as part of the power calculation. The quantity of material that bypasses the ball mill power calculation depends on the method used to simulate the phantom cyclone, but in general, the ball mill power calculation will see a smaller flow of coarser F. 80
