First, before the start of preparation: 1. Inspect all joints are secure, each rotary sliding parts are flexible and reliable. 2. Check the drive motor and power connections, jog the motor rotation direction is consistent with the observation direction of the work, or else the power to deal with the phase modulation. 3. Check the gas line, water is smooth. 4. Adjust the clamping mechanism, the first pre-pressed manually, then use the wrench to tighten 2-3 laps, bent conveying pipe, open the main gas line, the gas line shut-off valve, pressure gauge was observed at around 0.3MPa, rubber PCB at the availability of gas escape. 5. Appropriate adjustments to the various pneumatic valves, ensure adequate gas supply vibrating screen, vibrating well. Second, the spray operation 1. Open each gas line shut-off valve, open the nozzle valve, pre-wet rock surfaces. 2. Start the motor, pneumatic vibrator open valve, Hopper added Mixture began jet operations. The operator should work properly adjusted sprinkler water supply, make sure the concrete material has a suitable ratio. 3. Operating drivers observe the host side I porosity, such as surplus material discharge, should be appropriate to reduce the amount of gas under the gas path. I vent until the machine at no material discharged, the device is working so far. Third, other considerations 1. Before stopping, stop feeding, no material to be ejected when the head office, shut the water supply valve. 2. While adding a small amount to wet sand hopper to the hopper and rotor material cavity rinse residual material. 3. No material to be ejected when the head office, stopped the motor power, turn off all gas line shut-off valve, and the control switch is closed. 4. The class should be demolished discharge elbow, rotator rubber combination plate, remove the adhesive, demolition seat body, clears the body of excess material accumulated here and spraying machine body clean. 5. Feeding should be uniform, consistent with the spray operation, avoid crushing shaker phenomenon. 6. Prohibited by hand stirring gray material on the sieve.
