Shotcrete Machine SPZ-5

Gunite, also known as "dry process shotcrete", 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.

Features of Dry Mix Gunite Shotcrete Machine

1. the shotcrete machine is high efficiencyand quality
2. Spare parts of the machine is not easy to loss,and have a long service life.
3. Operation easily and it is convenient to maintenance
4. Environmental

1): Non-adhesion going through rotor with new material chamber, completely eliminate bonding and blocking during operation so as to reduce clearance and maintenance period;

2): Four-point clamping device make it easy to adjust the press between sealing plate and rotor disk so as to no air and dust leak and prolong consumption parts life;

3): Low pressure and low speed wortex air transport;

4): Well compact and seal, small dust, durable rubber plate;

5): Apply to steel fiber or chemical fiber concrete spraying.

Shotcrete Machine Structure Drawing

The structure and working theory of SPZ shotcrete Machine is shown as figure 1.

Thepremixed materials are filled into vibrating hopper 1, and then passing through vibratingsieve to hopper 3. From there it flows into the through-going chambers of rotor 7 by theaction of agitator 2 and moves to the discharge outlet with rotor running, where it isblown to Vortex Stream Implement 10 by compressed air leaded by air pipe 14. Here it isblown by scattering, accelerating, whirling, and floating vortex stream and through
conveying hose to the nozzle, where a little adjustable amount water (for damp-mix shotcreting) is added.

Shotcrete Machine mainly includes drive device, rotor assy., air conveying system, spraying system and electric control casing etc.
