Applications of RPB7 shotcrete machine: RPB7 wet-mix shotcrete machine can be used for the conveying and spraying of wet-mix concrete. Typical applications include permanent and temporary rock support in tunnels and mines, or wherever sprayed concrete is to be applied. It can also be used for pumping, grouting, concrete repair work, artificial soil seeding, mortar spraying, and refractory material spraying. Being a piston pump, it provides much more versatility than a rotor/stator pump of a similar capacity, in both mix types and potential conveying distances. Pumping of thick and plastic concrete also poses no problem, as the concrete is delivered up to 67bar.
Features:
Thick flow conveying method with hand-spraying make the concrete spraying is even, steady with less air consumption comparing to thin flow conveying method.
RPB7 is a high efficiency machine with long conveying distance, horizontal 120m and vertical 50m.
PLC standard electrical system controls provide fool-proof operation
Soft-start protects electric system and motor.
Two independent oil pressure circuits. Main oil is supplied by a high-pressure, variable-flow, axial piston pump. A gear pump provides separate circuit for the dosing pump.
A hand- wheel in dosing pump can adjust the emission of accelerating agent.
Double piston pump with S-tube and change-over cylinders for a positive action.
Self-sealing, high hardness sealing ring and plate.
Automatically reversing pistons relieve the conveying system when blocked.
Tough hopper with vibrator and grill designed for work with steel fibers.
Centrally positioned lubrication point for easy service.
Low weight is an advantage for transport.
Compact design enables easy integration into any kind of carrier chassis
