A lumber mill might use a predetermined maximum torque to initiate blade changes. This saves wear on the drive system and increase product quality.

Usually the charge volume of SAG mills occupy between 30-40% of its internal volume at which the grinding rate is maximized. When the charge volume is more, then the throughput suffers. The fill level is monitored by mill weight measurement as most modem mills are invariably mounted on load-cells.

the mill speed These variables will have a direct impact on mill load, torque, power draw and a slurry density Disturbances adding another degree of complexity to this control problem are ore size and the amount of circulating load Current Operation Strategy Often, in wet grinding operation there are no proper feedback control loops, but...

Wet Grinding Attritor, Continuous Mill All models can be equipped with a torque meter to precisely measure energy expended in the grinding chamber. Stationary arms can optionally be fitted into the tank wall in configurations best suited for your specific application. These arms are removable/interchangeable.

There is a large gap between the tip speed and power intensity of the low-speed vertical mills and the high-speed horizontal mills. The VXP mill bridges the gap between high-speed and low-speed mills. The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution
