Product Description

Product Description
Shotcrete machine can be divided into dry shotcrete machine, wet shotcrete machine and half wet shotcrete machine. Customers can choose the types according to their own requirements. Each type of shotcrete machine has advantages and disadvantages.
Dry Refractory Gunite Machine: Mainly for refractory spraying projects. It features a reasonable structure, humanized design, reliable performance, and convenient operation. It ensures long service life with no dust, low noise, and low rebound rate during operation.
Dry Mix Shotcrete Machine
Key Advantages:
● Greatly reduce dust concentration inside the machine and at the nozzle, protecting workers' health.
● High productivity for demanding projects.
● Low resilience: Wet spraying technology can reduce the resilience rate to less than 10%, compared to 15%-50% in dry spraying.
● Improved quality: Wet spraying allows for easier water-cement ratio control and high hydration degree, enhancing concrete homogeneity.
