Concrete Cement Pipe Machinery in Africa , Overview: Suspension roller concrete pipe making machines are used for producing reinforced concrete pipes and Pre-stressed concrete pipe. This kind of machine is capable to make pipes with diameter from 300-2000mm and with length from 1-4meters. We can design flat end, socket & spigot end, male & female end. All the concrete pipes are widely used in urban drainage, agricultural field irrigation, road culvert and deep water well. Working Principle: This XG series Concrete tube machine is with simple structure. The suspended roller passes through the tube mould. Driving by the motor, the transmission shaft will drive the roller rotating at a regulated speed. Because of the friction force between the roller and stop ring at the ends of mould, the pipe mould will be drove rotating at the same direction as the roller. z By manual feeding concrete or conveying machine, the concrete mixture into the mould will be adhere to the inner wall of mould, and become solid. Owing to the function of the Roller Compressing Force and Centrifugal Force, and then form a standard quality pipe. Features: 1. Wide Production Range: Inner Diameter form 200-2500mm, length 1-4meter. 2. Three kind of tube end joint: Flat end, Male& Female end, Spigot&Socket end. 3. High efficiency: Every pipe just need 3-5 minutes with high speed roller rotation. 4. Environment Friendly: Using dry casting concrete,no polluted slurry discharge. 5. Lower noise.
