Specifications

Technical data:

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.
• RISEN RPB7 is a high efficiency machine with a longer conveying distance, horizontal 200m and vertical 70m.
• Simple CE 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.
• Setting of the desired dosing values by hand-wheel
• Double piston pump with S-tube and change-over cylinders for a positive action.
• Self-sealing, superhard sealing ring and plate.
• Automatically reversing pistons relieve the conveying system when blocked.
• Tough hopper with vibrator and grill designed for work with steel fibres.
• Centrally positioned lubrication point for easy service.
•  Low weight is an advantage for transport.

Aplication

RISEN 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 in fact wherever sprayed concrete is to be applied. It can also for pumping, grouting, repair work, artificial soil seeding, mortar spraying, and refractory material spraying. Being a piston pump it provides much more versatility, in both mix types and potential conveying distances, than a rotor/stator pump of a similar capacity. Pumping of thick and stiff mixes also poses no problem, as the concrete is delivered up to 67 bar. Its compact design enables easy integration into any kind of carrier chassis.
