Concrete spraying machine is widely used in mines, tunnels, culverts, subways, hydropower projects, underground projects and coal mine roadway shotcrete construction operations; All kinds of walls reinforced with shotcrete concrete; Various types of industrial furnaces, furnace lining refractory spray molding or repair; Various slope protection greening construction, soil transport and injection. Its main characteristics and advantages: direct rotor type not bond chamber, discharging unobstructed, efficient time-saving: elastic compensation compaction at four o 'clock, good sealing effect, little dust machine, parts, long service life: using high-speed low pressure vortex air transportation, overcome the bonding in the material conveying, blocking pipe and pulse from the problem such as folding, uniform material flow, continuous and stable: new type of nozzle, the discharge elbow device, improve the effect of spray coated, springback is little, spray layer of high quality. The chassis of the machine can be assembled into wheel type, skid type and various gauge wheel type.
This machine can be used for wet spraying, dry spraying and various fiber spraying operations. Shotcrete is the use of compressed air, according to a certain ratio of concrete mixing materials through the pipeline and high-speed jet to the jet surface condensation hardening, thus forming a concrete support layer. In recent years, shotcrete technology has been widely used in construction, construction of iron highway tunnel, construction of mine shaft and roadway, slope reinforcement and other fields due to its simple technology, unique effect, economic cost and fast construction speed. Straight through the rotor - type non - bonded material chamber, smooth discharge, efficient time - saving. Low pressure, low speed cyclone, rarefied flow transmission, the material flow is uniform, stable, high strength jet layer. Four points elastic compensation clamping, good sealing effect, less adhesion to the machine dust, vulnerable parts long life.
