Diesel cement mortar sprayer machine
Diesel cement mortar sprayer machine has high quality and reliable performance; good sealing performance and less dust; reasonable design and easy to move; the four-point clamping device is convenient for adjusting the pressure between the sealing plate and the rotor disc, without air leakage and dust leakage, which prolongs the service life of the wearing parts. The thin flow conveying method and vortex conveying are adopted to make the jet uniform, continuous, and stable, which improves the quality of shotcrete.
The diesel cement mortar sprayer machine is a medium-sized shotcrete machine suitable for the dry spraying process. It is widely used by many contractors.

The diesel cement mortar sprayer machine has a rotor feeding system, which remains upright after each work to ensure a long service life and low maintenance costs. We can provide several hose and nozzle options to meet the needs of shotcrete applications. It is widely used in concrete spraying operations in tunnels, culverts, subways, hydropower projects, underground projects, and high-gas tunnels in coal mines.

As a diesel dry shotcrete equipment supplier, we have more than ten years of production experience. The following models of diesel cement mortar sprayer machines are available:
1. Pneumatic motor drive or diesel drive combined with slide rails or track wheels.
2. Basic type: electric drive can be used in combination with a tire chassis.
3. Extended type (optional): electric motor drive with variable speed gearbox, pneumatic motor drive, or diesel drive combined with slide rails or track wheels.
