A larger model has been added to the SJD Series of low-speed, screenless granulators from Wittmann Inc., Torrington, Conn. Designed for large, bulky parts, Model SJD8-3 has a larger cutting chamber and longer twin shafts with an extra roller section and breaker knife. The optional third shaft breaks up parts in the hopper before they reach the cutting chamber. The new model has a cutting chamber of 20.9 x 23.1 in., vs. 20.9 x 18.4 in. for the next-largest model. The SJD Series runs at 32 rpm and has blades that cut at a tangential angle. In case of a jam, auto-reverse is standard.
