Pneumatic drive SPZ - 3A shotcrete machine with air motor explosion proofing working

Detailed Description of SPZ-3A Air motor 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.

Technical specification of SPZ-3 Pneumatic motor Dry Mix Shotcrete Machine:

Features of SPZ Series Pneumatic Dry 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 service life.

Applications of shotcrete machine:

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.

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 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.

Drive type of Pneumatic motor 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 power.
• 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.
