Decription: PZ-7 dry mix shotcrete machine is a universal medium-sized shotcrete machine.
Application: Used for dry-mix concrete spraying in tunnelling, culvert, subway, slope stabilization, swimming pools, mining and underground engineering; The explosion-proof type is suitable for coal mining, chemical mine and other places with high combustible gas.
1. Enlarge feeding inlet facilitates the continuity of concrete output. Air flow can be set at a certain rate, also can be adjusted timely to ensure the continuity of the concrete and accelerator.
2. New straight-through rotor, macromolecule elastic chamber, combined and soft discharge elbow and rubber liner prevent concrete sticking and blocking in the machine.
3.Wear parts are made of the materials with unique structures. Elastic and automatic clamping device improves tightness of the machine and reduce the wear of parts.
