2021-2-15 · Whether a mill is single or dual pinion, high- or low-speed, ABB offers the right solution. Motors are fed by frequency converters that allow speed variation and soft control during starting and stopping of the mill. When a dual pinion configuration is applied, care must be taken to ensure the load is shared equally between both pinions.
