The North Pole Mine and stamp mill as it looked during the boom years. The stamp mill, below Bourne, was a mile and a half from the mine, connected by a tramway of 7/8 inch cable with 200 buckets of 250- pound capacity. The North Pole was a very successful mine, but by the time Wallace White arrived, its best years were behind it.

Improved process control and increased ball mill operating power draws have reduced the grind size back to around 150 to 160 µm at the elevated throughput rates. The regrind plant consists of two Verti-mills (one duty and one standby) with product reporting, via cyclone clusters, to the cleaner flotation plant.

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

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 ...

For ball milling, you can assume a porosity of about 0.35 to 0.40 (the volume of space between the balls) and you can normally assume the pulp surface level is equal to the ball charge surface level. So do a crash-stop and measure the volumetric filling of the charge, then multiply that volume by 0.35 or 0.40.

Ball & Rod Milling The Hardest Performance. ... The positive location between the moil, or drift, and the bolt eliminates the risk of mill damage due to misalignment of hydraulic hammer moils or sledgehammer damage around bolt holes.
