Unique to McLanahan designed primary and secondary DDC-Sizers is hydraulic adjustability of one of the sizing rolls. This feature allows producers not only the option of maintaining original size specifications when crushing, but also gives them the ability to adjust if product size requirements change. The hydraulic adjustable roll also allows producers to control product specifications when compensating for tooth wear.
DDC-Sizers have a direct drive arrangement and low-profile design that allows wheel mounting for a movable configuration. The preferred method of installation is to mount the unit on rails with a non-rigid connection between the feed and discharge chutes. Since the drives are attached to the mainframe of the sizer, the entire unit can be rolled out from the feed stream to facilitate maintenance. McLanahan DDC-Sizers are equipped with hydraulic lift cylinders for ease of wheel activation.
