Zhengzhou Sincola SPZ Dry and wet ready mix concrete shotcrete machine tunnel construction
Detailed Description
SPZ series dry mix shotcrete machine, also named concrete guniting machine, mainly used for dry-mix concrete and damp-mix concrete spraying operation. It has some obvious advantages such as advanced technology, Perfect structure, stable performance, convenient operation and longevity of service etc. It is widely used for concrete pump spraying working in building, mining, tunnel, culvert, subway, hydropower engineering, underground excavation engineering, swimming pool building, slope protection etc.

Working Principle
Mixed concrete is fed through the vibrating screen to the spraying machine’s charging hopper by the concrete mixer (or manual mixing and feeding). Then, concrete mix is moved by a poker to rotator’s through chamber, transferred to discharging outlet along with the movement of rotator, where compressed air from air chamber blows the mix to outlet elbow. Another blow of compressed air from the rotational swirler will further scatter, accelerate and rotate the mix to the conveying hose. Concrete mix is sprayed out through the sprayer where a little water (applicable in damp spraying) or liquid accelerator (applicable in wet spraying) is added.
Advantages:
High effective concrete spraying working, Easy operation, Stable performance;
Rotor Disk: There are two rotor disks on the opposite sides of rotor, it is made of high-qualified alloy steel and can handle concrete more than 4000m3 during its working Period.
Rubber Sealing Plate: There are two plates (upper and lower). Both of the upper and lower plates are made of anti-abrasive special rubber and can handle concrete 300-400m3 during its working period.
Clamping Device: By this device, the force is acted through the screws and cylindrical springs, which works as elastic auto-clamping device. Tight clamping by the turnover frame floating can provide a constantly uniform pressure at the sealing surfaces with a high tightening effect and low dust emission, and can avoid rubber plate over-worn, too.
