Mining coal-fired shotcrete machine can be used for both tide spraying and dry spraying and various fiber spraying operations. So must the coal mine shotcrete machine adopt a mine shotcrete machine?
Application scope of mine shotcrete machine: Mining coal-fired shotcrete machine can be used for both tide spraying and dry spraying and various fiber spraying operations. It has the characteristics of reasonable structure, stable performance, convenient operation and maintenance, and long service life. Widely used in mines, tunnels, culverts, subways, hydropower projects, underground engineering and coal mine marsh mine roadway sprayed concrete construction operations; various wall reinforced sprayed fine stone concrete; various types of industrial furnaces, furnace linings, refractory materials Or repair; soil transportation and spraying during various slope protection and greening construction.
The working principle of the mining shotcrete machine: First, the construction staff will stir a certain proportion of the cement sand and small stones and an appropriate amount of water through the mixer to form a uniform wet mix, and then enter the mine shotcrete belt feeding machine. The feeder conveys the mixed material to the screen of the jet machine, enters the hopper under the operation of the vibration motor of the spray machine, and injects it into the material cavity of the rotor assembly. The material cavity rotates the material to the discharge port with the rotor body, passes compressed air from the gas path system, and blows the material into the discharge elbow. The cyclone introduces another stream of compressed air to form a multi-head spiral to accelerate the material and disperse and It rotates and floats into the material tube and reaches the nozzle to spray the sprayed surface! During the work of the mining shotcrete machine, it is as far as possible to ensure the smooth feeding, and to achieve the wet concrete spraying operation. In the construction of mining shotcrete machine, the dust concentration near the machine is low (less than 10 mg per cubic meter), the environmental pollution is small, and the rebound rate of the shot is small (5% -10%), which can effectively improve the shot quality and reduce the construction cost.
Different flammable gases often appear in the mine. The use of the mine must use a mine shotcrete machine.
