Cam grizzlies, mod. GC are perfect for pre-screening and for cleaning large rocks or tout venant materials, even if they contain high percentages of moisture or dirty materials. These machines are particularly sturdy, ideal to work in any condition.
They are composed of a carrying frame on which the cam carrying shafts are fixed and they are connected by a transmission chain. The grooved rollers or cams mounted one in front of the other create virtually opening thus forming a grizzly for the passage of the dirt.
The particular shape of the cams causes an undulatory movement on the machine surface thus facilitating screening.
The material cleans the cams by itself and thus prevents clogging.
The mechanism is driven by en electric motor and a reduction gear.
