GZ-9L compared with the traditional spraying and conveying machine, it has several advantages: hydraulic floating compression (pressure automatic compensation after the rubber sealing plate is worn), hydraulic turning hopper house, hydraulic lifting rotor body, automatic anti-blocking function, rubber seal plate automatic lubrication, the locally control mode and remote control function with PLC control system, which greatly enhance the degree of automation of the machine and increase the machine efficiency. Therefore, this machine is installed into the TBM for the pea gravel spraying, as well as it is widely used in mines, tunnels, culverts, subways, hydropower projects, underground projects, etc.
