PST shaftless conveyors work like a big screw – without the centre shaft though – and this allows difficult material that would normally get bound up around a shaft, to be conveyed easily. The loose material can be conveyed vertically or horizontally.
They are ideally suited in applications where space is limited and access is too difficult using standard belt type conveyor. Being fully enclosed dust is also contained which keeps the workplace clean and dust-free. They are ideally suited to bulk material transfer situations from wood chips to mineral products
