Technical data
■ Description
GPS-7 multi-function wet spraying machine adopted internationally hydraulically driven wet spray technology, thus transmission distance and height increased 3-5 times than the rotor wet spray machine.
■ Application
GPS-7 multi-function wet spraying machine is mainly used for wet spraying for roads, railways, mining and tunnel, spraying mixed vegetation for slope of road and railway, grouting for wall, pumping fine aggregate concrete and so on.
■ Features
1. Wet spraying machine has stepless speed change. The conveying output is 0-7 cubic meters / hour.
2. The machine has hydraulic power. The export is connected with high pressure hose. The nozzle is connected with a small 10 cubic meters of air compressors to achieve wet spraying. This changed the traditional use of large 20 cubic meters of air compressor.
3. Compared with rotary pneumatic wet spraying machine, this machine has a smaller size, superior performance, lower maintenance costs, easier to operation, better flexibility, and widely range of applications.
