Shotcrete process is to use compressed air to convey the pre-dampened mix through delivery hose to the nozzle to project the material onto the sprayed surface under high velocity, and then to form concrete support layer after the projected material coagulates and hardens. With simple technology, special effect, economy cost, flexibility and high construction efficiency, shotcrete technology has widely been applying in construction, railway and super highway engineering, underground engineering, tunneling, mining operations, hydropower projects and slope stabilization, etc. and showing prosperous future.

SD-3 is SUG small-sized shotcrete machine/equipment for the dry spraying process.
SD-3 can be used as well for small jobs, such as joint filling., swimming pool, refractory application work,etc.
SD-3 is available in following versions
Basic: electric drive can be combined with tyre chassis
Extended (optional): air motor drive combined skid or with single hydraulic power pack Skid or Rail-wheel

Features

Non-adhesion going-through rotor with new material chamber, completely eliminate bonding and blocking during operation so as to reduce clearance and maintenance period.

Thin flow conveying method with vortex flow, so the spraying flow is even, continuous and steady, to improve the shotcrete quality

Four-point clamping device make it easy to adjust the press between sealing plate and rotor disk so as to no air and dusk leak and prolong consumption parts life
