Product Description

PZ-7B Mining Explosion-proof Spraying Machine
Other Names:Shotcrete machine; Explosion-proof spraying machine; PZ-7B
Product Introduction
PZ-7B-type spraying machine is an equipment used for dry spray, tidal spray. It has the features of advanced technology, reasonable structure, stable performance, easy operation and maintenance, construction shotcrete machine long life, can be configured separately tire and wheel tracks two kinds of walking device.
PZ-7B mining Explosion-proof gunite machine is a mine dry shotcrete machine, the working capacity is 7m ³ / h, power is 7.5KW,the vertical conveying distance ups to 20M.
Usage
After mixed cement, sand, stone a certain proportion, PZ-7B mining explosion-proof gunite machine used compressed air as the power to spray to the surface with a high-speed after nozzle is mixed with water. It mainly used to spray the concrete mixed by sand, cement gravel. But the stones diameter should be less than 20mm , so as to ensure the injection of fluency.
PZ-7B mining explosion-proof gunite machine is mainly used in mine shaft, tunnel, caverns andother support and structural reinforcement and concrete building construction.
