New refractory concrete spray shotcrete gunite machine for coal Mine Spraying
New refractory concrete spray shotcrete gunite machine for coal Mine Spraying uses compressed air to transport the concrete mixture in a certain proportion through the pipeline and spray it at a high speed to the sprayed surface to set and harden, thereby forming a concrete supporting layer.
New refractory concrete spray shotcrete gunite machine for coal Mine Spraying uses compressed air to transport the concrete mixture in a certain proportion through the pipeline and spray it at a high speed to the sprayed surface to set and harden, thereby forming a concrete supporting layer. In recent years, refractory shotcrete technology has been widely used in construction, railway and highway tunnel construction, mine shaft construction, slope reinforcement, and other fields due to its simple process, unique effect, economical cost, and fast construction speed.
