Precautions when using a gunning machine for refractory

1. Preparation before the start:

A. Make sure that the contacts of each circuit of the electrical control system are solid and that there are no leaks.

B. Observe the oil mark to make sure there is enough lubricating oil in the speed reducer.

C. Make sure that the fastening of each part of the machine is correct and reliable.

D. Run the machine for a short time to understand the rotation status (make sure the direction of rotation matches the direction of the arrow. Look counterclockwise from above, but for a long time Do not idle).

E. Check the clamping force applied to the rubber sealing plate.

2. How to start the spray (gunning) operation:

Once the preparatory work is complete, the composite can be added to the machine. At this time, the machine operator must first open the main valve and then adjust the down duct. The spray (gun) operator then opens the nozzle water valve to wet the spray surface. At this point, the machine operator can start the machine and begin refractory injection work.

3. Stop spraying.

A. Stop the machine and blow off the rest of the material in the transport pipeline.

B. If the pipeline is clean, no material will be ejected from the nozzle.

C. Finally, close the main air pipe his valve.

4. Notes:

Strictly prevent long, large objects such as steel bars, iron plates, etc. from entering the cavities of the rotor material during use and causing large collisions.
