1. Description of the Production Roller hanging type concrete pipe machine is a kind of machine to produce concrete pipes and Pre-stress concrete pipe. This machine use the roller to support the pipe mould,and produce roller force to the concrete in the mould. When the roller rotate at a high speed, the concrete in the mould will spread in the inner wall of the pipe mould and form a cement pipe with the centrifugal force. And when the mould with the inner concrete pass on the roller, the concrete between the mould and roller will be compacted solid to form a pipe(This machine uses the rotation of roller axle and steel mould to produce rolling pressure and centrifugal force and makes the mixed cement material shape into a pipe).It can make pipes with diameter from 300-2400mm and with length from 2000-5000mm. We can design many kinds of pipe joint, including flush joint(flat mouth type), groove joint, socket and spigot joint(socket and plug mouth type) ect. And all the concrete pipes are widely used in admistrative drainage, agricultural field irrigation, rood culvert and deep water well . 2. This machine has lots of advantages : (a) short production cycle :because of the good effect of the roller to compact the concrete, every pipe just need 10 minutes with high speed roller rotation. (b) This pipe use the dry cast material, there will no waste cement mud, then it will not pollute environment . (c) During the production, the noise is very low, it is about 80-90 dB (d) The concrete pipe is with high pressure load and with high production efficiency. (e) This machine is simple in operation, rotates steadily, is reliable and durable in use, is low in fault rate . We welcome new and old customers to contact us for business.
