Reasons and solutions for the garnet sand not coming out during the sandblasting machine?
Reason 1: Too much sand is added, which causes blockage and cannot be pressurized.
Solution: The amount of sand added should be appropriate, not too much.
Reason 2: The spray gun is blocked.
Solution: After stopping the gas, remove the nozzle to see if there is any foreign body. If there is any foreign body, just clean the foreign body.
Reason 3: The sand pipe is blocked.
Solution: After the gas is stopped, remove the nozzle, turn on the sandblasting machine, and blow the foreign matter out with high-pressure gas. If there is no effect, the pipe has to be removed for cleaning or replacement.
Reason 4: The sand material is wet.
Solution: Clean up the nozzle of the spray gun, and dry and filter the sand.
Reason 5: There is no filter screen, causing large foreign objects or uneven sand to enter the sand valve.
Solution: Open all sand adjustment valves, and use strong air to remove foreign objects or agglomerated sand materials. If this does not work, you can only release the sand, filter it again, and add it in.
Reason 6: Too little sand
Solution: Turn off the sandblasting machine and air source, and add sand.
