How to properly operate a dry shotcrete machine? China Coal Shotcrete Machine suppliers introduced the dry shotcrete machine operating rules in detail, and hope that it will be helpful for everyone to operate dry shotcrete machine.
Dry shotcrete machine spraying process
First, open the main gas path, upper gas path, lower gas path stop valves, open the nozzle water supply stop valve, pre-wet the rock surface, then start the motor, open the vibrator air path stop valve, add the mixing material to the hopper, and start spray operation. During the work, the sprinkler operator should appropriately adjust the water supply of the sprinkler to ensure that the concrete has a suitable water-cement ratio. The operator of the shotcrete machine should pay attention to the remaining air holes on the side of the main machine. If the remaining material is discharged, the air supply of the lower gas path should be appropriately reduced. Until no material is discharged from the remaining air outlet of the shotcrete machine, the equipment works normally.
Dry shotcrete machine shutdown operation
Before stopping, first stop feeding. When there is no material spraying from the nozzle, close the water supply shut-off valve and add a small amount of wet sand and stone to the hopper at the same time. Wash the residual material in the hopper and the rotor cavity several times. When the material is ejected, turn off the power to the motor and each gas path stop valve.
