Home Full portfolio Mill power draw increase
Draw more power, increase throughput, and maximize production with your existing mill.
Your challenge
Your challenge

Mills are originally sized for specific running conditions. Declining ore grades and increasing hardness makes supporting the market demand more challenging. As a result, improving throughput becomes a top priority.

It is, however, possible to increase throughput by maximizing the power draw of your existing mill without having to install additional equipment. 

The Metso Outotec solution

Our engineers will help identify your goals for increasing your grinding efficiency.  Our grinding experts will then evaluate the current condition of your mill by conducting a mechanical study, providing recommendations, and supplying customized parts.

The study can include making adjustments to the mill power and mill speed, a review of the structural capacity of the mill rotating body, bearings, and foundation loads as well as a review of the drive components.  A process study can also be performed should additional information be required.

Achieving power draw increase
Achieving power draw increase

Power draw increase can be achieved with one or more of the following:

  • Increasing ball charge or volumetric loading, including a combination of replacing the feed and discharge end configurations and installing new drive components with higher mechanical ratings to sustain increased power draw
  • Adjusting speed with additional teeth on the pinion or adding, for example, a VFD (variable frequency drive) and torque limiting coupling
  • Re-configuring the discharge end by converting from an overflow system to a grate discharge system (specific to ball mills) or installing an AG/SAG mill curved pulp lifters for material to exit faster

We provide custom-design parts, technical support and installation for a turnkey solution.
