■ Description

GZ-9E/S Wet & dry sprayed concrete linings and convey pea-gravel machine is a multifunctional rotor type machine for wet and dry spraying and conveying. The materials that can be sprayed and conveyed are concrete, mortar, refractory, sand, pea gravel and crushed stone. It is a rotor machine able to apply wet & dry sprayed concrete linings and to convey pea-gravel, with effective outputs up to 3-9.5 m³/h.

Compared with the traditional spraying and conveying machine, GZ-9E/S Media has several advantages: hydraulic floating compression (pressure automatic compensation after the rubber sealing plate is worn), hydraulic lifting rotor body, automatic anti-blocking function, automatic lubrication, the local 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 widely used in mines, tunnels, culverts, subways, hydropower projects, underground projects, etc.

■ Application

GZ-9E/S Wet & dry sprayed concrete linings and convey pea-gravel machine find its main field of applications in tunnels’ projects, slopes’ consolidations, channels’ restorations etc. The GZ-9L machine’s flexibility both in terms of workable mixes and outputs ranges, allows a very wide field of applications. The GZ-9E/S pea gravel conveying machine for TBM is as well widely adopted for the pneumatic conveyance of peagravel when tunnelling with a TBM.

■ Technical data

Specification (with Electric motor drive):
1. Automatically clean delivery line blockage: PLC+VFD+Air Pressure Sensor. 2. Sector hole to replace the circle hole in the rotor to improve the volume of the rotor and to decrease friction area, then with the same output, the rotor speed will be lower to improve the work life of the rubber sealing plate and keep the motor power lower. 3. Hydraulic floating compression (pressure automatic compensation after the rubber sealing plate is worn). 4. To add an automatic lubricator to the rubber seal plate to make the work life of worn parts longer and make the motor power lower. 5. Intelligent anti-clogging pipe system.
