How hard is your hard ore? Has the ore been tested and shown to be suitable for SAG milling? If the hard ore only comes to the plant from time to time the options are many options, including: accept a reduced throughput for a short time (minimum capital case); increase pebble crushing capacity and/or reduce crushed product size; return crushed pebbles to ball mill, bypassing the SAG mill.

There are lots of different kinds of crushers from jaw crushers to impactors and cone crushers. Crushing is an versatile process and the kind of crusher you need depends on the 'stage' of crushing. The three main stages of crushing are primary, secondary, and tertiary all of which have their own unique benefits.

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 ratecontrolling device, but with a feed bin) to crush pebbles for recirculation back to the SAG mill feed ...

Semiautogenous (SAG) mills are widely used grinding equipment, but some ore with critical particle sizes cannot be effectively processed by SAG mills and turned into pebbles. This research aims to analyze and compare the properties of raw ore and pebbles from a zinc and tinbearing ore. The results show that the contents of sphalerite, cassiterite, biotite, antigorite, pyroxferroite ...

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

The "pinion power" is the mechanical power available at the output shaft of the motor and is related to the torque required to turn the mill and the mill speed. If you remember back to your electrical engineering courses, the power available in a circuit drops due to losses as you move down the circuit (because each electrical item causes a ...
