Philadelphia Gear's rugged, high-torque cement mill drives are vital links in the manufacturing process of cement plants worldwide. Bevel-helical and bevel-epicyclic roller mill drive designs have been supplied by Philadelphia Gear for roller mill applications, and primary motor driven parallel shaft reducers (which drive final reduction pinions and girth gear sets for grinding/ball mill applications) have been a particular area of excellence at Philadelphia Gear for nearly a century.

Most recently, central mill split-train epicyclic designs have been developed and supplied to the industry. These units, in particular, are compact and offer enhanced maintainability - important because cement mill drives are difficult to assess and repair, and are often pushed to the output capacity of their design. Plants utilizing Philadelphia Gear's inspect and repair service can have these units repaired and rebuilt to their original specifications - or even engineered to higher speed or load carrying capabilities. Plus, these plants can benefit from other innovative solutions from Philadelphia Gear.
