With the clod separator,clods and stones can be separated from a flow of potatoes in a dry way. The operating principle is based on the difference in bounce behaviour on a radial fixed roll. The potatoes with clods and stones are conveyed to a rotating drum. This drum turns in the opposite direction of the product flow. Thanks to the difference in bounce behaviour, the clods and stones are separated from the potatoes and fall straight down. The potatoes bounce off of the drum, via a separation plate, into a crate or onto a conveyor. When you have a clod separator with two drums, it is possible to achieve a separation percentage up to 90%. De rotating drum and separation plate are easy to adjust. The capacity lies between 3 and 20 t/h. Optionally, the machine can be equipped with conveyors.
