The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the …

Yes, we can assist with optimisation. To achieve this at both the design and operating stages, we will require some representative sample for specific comminution test work. The test work will entail industry standard tests such as the Bond Rod Mill Work Index, Bond Ball Mill Work Index, JK/DWi tests and then some specific batch mill tests.

Ball mills account for the majority of all mills in cement plants and therefore the optimization of established ball mills implies high savings potentials. Use of suitable grinding aids also is recommended to improve grinding. BSNL JTO 2007 RESULT PDF. The mill is ventilated by an induction fan.
Ball mill circuit classification system performance is considered here first because it provides the basis for subsequent characterization of ball mill breakage efficiency. Major design and operating variables in closed circuit ball milling of a specified feed to a desired product size are summarized in Table 1.
The final plan was to increase the ball charge in the SAG and ball mill to 10% v / v and 27% v / v, respectively; set the upper limit of the operating power in the ball mill to 5800 kW; use a TC Series crusher (without a power-/feed rate–controlling device, but with a feed bin) to crush pebbles for recirculation back to the SAG mill feed ...
