The Rotary Macerator is an Industrial Craft 2 machine, the advanced version of the Macerator. Like the other advanced machines, the Rotary Macerator increases in speed through constant operation or by applying a redstone signal to any face of the machine. The machine caps its speed at 7,500 RPM, though this increases by 500 RPM per Overclocker Upgrade placed in the Rotary Macerator's upgrade slots.
The Rotary Macerator is a Low Voltage machine and can only accept 32 EU/t. If one wishes to connect the Rotary Macerator to the MFE, MFSU, or any of the Medium and High Voltage generators, a Transformer Upgrade is required.
The Rotary Macerator's GUI has a second slot for modifier items. For example, rather than macerating Copper and Tin separately and then crafting them together, macerating Copper with Tin in the modifier slot will produce two Bronze Dust per Copper, consuming the Tin after every four Copper.
