■Introduction

 Description:

LZ-9L Shotcrete system for tunnel boring machine is a multifunctional highly efficient rotor machine for
wet & dry sprayed concrete applications, with effective outputs included between 3-9m³/h. 
The
materials which can be sprayed and conveyed are concrete, mortar, refractory, sand, pea gravel and
crushed stone.

LZ-9L shotcrete machine for TBM 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
tunnels’ projects, slopes’ consolidations,
channels’ restorations etc.

 Application:

LZ-9L automation shotcrete machine for TBM is widely adopted for the pneumatic conveyance of
pea-gravel when tunnelling with a TBM. The 
shotcrete machine machine’s flexibility both in terms of
workable mixes and outputs ranges, allows a very wide field of applications.
Therefore, this 
automation shotcrete machine for TBM 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.
