autogenous mills – commonly known as SAG mills – use milling balls, as well as the weight of the ore itself, to break down the ore into smaller particles – a process known as comminution. The turning and tumbling of tons of ore within these mills creates a harsh environment with high heat and constant vibration. Downtime for these

Operating principle of Vapromatic type LRS. This is based on the difference in resistivity between a liquid electrolyte and its vapour, contained in an electrode chamber. The passage of the initial rotor current causes immediate partial vaporization of the electrolyte and instantaneously adjusts resistance and starting torque to optimum values.

time-taking grinding out of the ball mill. Ball mills with Energy savings typically up to 750,000 USD per annum for a 20 MW SAG mill considering a power supply price of 11 US Cents per kWh. Erection and commissioning works on site are reduced by using a completely installed, wired and pre-commis-sioned E-house.
