The machine takes sands, stones and cement as raw materials to produce many kinds of reinforced concrete drainage pipe with the length of 1000-4000mm, internal diameter of 200-4000mm with the mouth shapes of flat, tongue and groove and socket and spigot. All mechanical indexes have meet the national standards. They have been used widely in deep well, municipal drainage, expressway and other water supply and sewerage works with higher level required. The production efficiency can reach 4-5 piece/hour.
2. Features of Centrifugal type Concrete Pipe Machine
The centrifugal machine is mainly used to manufacture the centrifugal equipments manufacturing the reinforced concrete drainpipes, driving the spinning of the drainpipe concrete pipe mold loaded with some concrete and reinforcing steel with a certain mixing ratio at different speeds, and the solid phase particles of concrete in steel mould will be centrifugal settling in the steel mould inner surface under centrifuge, meanwhile draining the excessive water, thus forming compacting concrete structure namely reinforcing concrete drainpipe. The machine mainly consists of riding wheels, shafts, bearing block, bearing, V-blet pulley, base and electromagnetic speed-controlling motor.
