Wet Mix Shotcrete Machine

Inquiry Overview | Technical Parameters | Introduction | Applications | Working Principle | Inquiry

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.

  • Introduction Of Electric Dry-mix Shotcrete Machine

    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 wet-mix Shotcrete Machine is a low to high production, continuous-feed material placement unit for wet-mix gunite or refractory materials. Wet shotcrete machine 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.

    Features Of Wet-Dry Mix Shotcrete Machine

    • electric drive can be combined with tyre chassis.
    • Air motor drive or diesel drive combined with single hydraulic power pack.
    • Skid or Rail-wheel.

  • Working Principle of Wet-Dry Mix Shotcrete Machine

    With "wet-process shotcrete" a low-slump concrete mix is pumped with a Concrete Pump to the end of the pipeline. conveys the pre-dampened mix by compressed air. the pre-concrete is mixed firstly . and then putted into shotcrete machine. This compressed air typically comes from a 165-185cfm air compressor - sold separately. The addition of the compressed air adds velocity to the concrete so it sprays out of the nozzle. This velocity, combined with the low slump of the shotcrete mix, allows the concrete to be sprayed on slopes, vertical walls, and overhead .
