DDC-Sizers
DDC-Sizers are an evolution of the Double Roll Crusher.  McLanahan Corporation has been designing and manufacturing this type of crusher since the 1960's, having first introduced them to the brick and clay industry for handling wet, sticky feeds. With a low profile, low headroom design, this crusher excels at primay, secondary, and tertiary reduction.

McLanahan Corporation offers DDC-Sizers in either single or dualdrive configurations. Power is transmitted to the roll(s) via a heavy-duty educer either " right-angle" or " inline-to" the rolls, depending upon the application and structural limitations. Tramp iron protection is accomplished via a torque controlled coupling located between the motor and reducer. Direct hydraulic drives are also available for extremely tough applications to reduce shock loading.

One of the unique features on the dual drive DDC-Sizer is the adjustability of one roll assembly to control product size and to compensate for roll wear. This is accomplished by using independent drives (motor, coupling and reducer) for each roll assembly. The end result is a more cost effective crusher.
