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.

1.Used for dry mix concrete spraying operation;
2.Shotcrete for Civil Underground Foundation , Express-Way Construction,Railway Construction;
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.
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 accessories;
E, Powder accelerator is manually added, uneven, increase raw material rebound,
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.
About the shotcrete machine, we have electric power drive type, diesel engine drive type and air motor drive type for choice.
