LZ-9L Rotary machine for pea gravel backfilling is a multifunctional rotor type machine for wet and dry spraying and conveying. The materials which can be sprayed and conveyed are concrete, mortar, refractory, sand, pea gravel and crushed stone.
LZ-9L Pea gravel backfilling machine installation on TBM has reliable high conveying performance and outstanding quality properties. 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.
The pea gravel backfill concrete spraying and conveying machine find its main field of applications in tunnels’ projects, slopes’ consolidations, channels’ restorations etc. Gaodetec pea gravel backfilling rotary machine conveying up to 10x more than conventional machines without changing the wear plates. Finally LZ-9L Rotary machine for pea gravel backfilling is widely adopted for the pneumatic conveyance of pea-gravel when tunnelling with a TBM.
1. Hydraulic lifting rotor body.
2. Hydraulic turning hopper house.
3. Pea gravel backfill handling in large tunnels with conveying hose automatic anti-blocking function.
4. Pea gravel backfill injection equipment with rubber seal plate automatic lubrication.
5. Locally control mode and remote control function.
6. If pea gravel transfer system adds the dosing pump, it can be used for wet shotcrete.
7. Hydraulic floating compression (pressure automatic compensation after the rubber sealing plate is worn).
