Tunnel Mobile SPZ-3D diesel drive shotcrete machine for 20mm
Detailed Description of SPZ-3D DIESEL Dry Mix Shotcrete Machine:
Dry Mix Shotcrete Machine, also name Gunite machine, uses a
different process than wet process shotcrete. Gunite machines use
air pressure to convey dry material from the machine through the
hose to the nozzle where water is added. SPZ Series Electric
Dry-mix Shotcrete Machine is a low to high production,
continuous-feed material placement unit for dry-mix gunite or
refractory materials. It is equally at home underground in a mining
environment as it is on a construction jobsite. This kind gunite
machine has a rotor feed system, which stands up job-after-job to
ensure a long service life with low maintenance. Several hose and
nozzle options are available to meet the demands of every gunite /
shotcrete spraying application.

Features of SPZ Series Diesel Dry Mix Shotcrete Machine:
1. SPZ Series Dry Shotcrete Machine can be driven by electric
motor, diesel engine, and pneumatic motor.
2. Dry Shotcrete Machine are consisted of driving device, rotor
assembly, air system, concrete spraying system, control panel,
electric motor (diesel engine, or pneumatic motor) etc.
3. Dry Shotcrete Machine have advanced technology, compact
structure, convenient operation, stable performance and long
Applications of shotcrete machine:
1.Used for dry mix concrete spraying operation;
2.Shotcrete for Civil Underground Foundation , Express-Way
3. Shotcrete for building surface;
4. Shotcrete for Tunneling , Mining ,Hydropower Project;
5. Shotcrete for Slope Stabilization;
6. Apply to steel fiber or chemical fiber concrete spraying.
For example, build up the swimming pool.
Advantage of shotcrete machine:
A, seal structure is not good, dust pollution is serious;
B, serious air leakage, easy to plug, low spraying efficiency;
C, more material rebound, waste serious;
D, parts wear serious, need more wearing parts, high cost of
E, Powder accelerator is manually added, uneven, increase raw
F, due to the loss of cement dust, water is not uniform and large
rebound , result in the change of the concrete raw materials rate,
reducing the quality of concrete.
Drive type of the shotcrete machine:
About the shotcrete machine, we have electric power drive type,
diesel engine drive type and air motor drive type for choice.
- Electric power drive type: price is lowest, working need electric
- Diesel engine drive type: price is higher than electric type,
suitable for no electric, or less electric power work site.
- Air motor drive type: price is highest than electric type and
diesel type, suitable for explosion-proof special environment.
