Usually, the cleaning style tubular centrifuges have two forms of structure, open-type  and closed-type. The structure and processing of closed-type are very simple, so the closed-type ones are in a low cost. The disassembling operation of bowl is pulling it out from the machine’s top. The open-type has a opening door, users open the door, then they can take the bowl directly. That can reduce the labor intensity effctively, at the same time, the open-type ones cost more than the closed-type. The open-type tubular centrifuges also can replace the swing body tubular centrifuges.
