Summary：We've had a lot of discussion about the sand making machine. In operation, it's inevitable that sand making machine will encounter a variety of problems.
We've had a lot of discussion about the sand making machine. In operation, it's inevitable that sand making machine will encounter a variety of problems. Once sand maker being in breaking down, it will affect the production efficiency and then affect the economic benefits.
Today we will provide you with a summary of 10 common failures and teach you how to deal with them. I hope this article will help you in the future if you encounter such problems.
Fault 1: The equipment is not running smoothly with overmuch fuselage swings
Cause:
▶The wearing parts on the impeller wear seriously.
▶Feed size exceeds the limit.
▶There is some blockage on impeller runner so that the machine shakes seriously.
Solution:
▶Replace wear parts to balance the inner impeller of sand making machine.
▶Strictly control the material size lest it exceeds the maximum allowed by the equipment.
▶Remove the blockage from the impeller runner and keep clean crusher chamber regularly.
Fault 2: The equipment made abnormal noise during operation
Cause:
▶Some wear parts inside the sand making machine loose or fall off (such as bolts, lining plates, and impeller).
Solution:
▶Stop the machine immediately and retighten and install the parts.
Fault 3: Bearings are not flexible
Cause:
▶Some foreign matter entered the bearing seal cover of the sand making machine.
Solution:
▶Open the machine cover and loose foreign materials.
Fault 4: High temperature of bearings
Cause:
▶There are dust and other foreign matter in the bearing parts
▶The bearing is worn off.
▶Lubrication oil shortage
Solution:
▶Clean the blockage
▶Replace with a new bearing
▶Add lubricating oil regularly
Fault 5: The sealing rings of the shaft are damaged
Cause:
▶The axle sleeve caused heat by rubbing gland underside, which will cause damage over time.
Solution:
▶Replace the upper and lower sealing rings.
Fault 6: Oil soaks into the upper and lower end of the shaft
Cause:
▶Because seal rings need to move up and down with the bearing, which resulting in wear and oil leakage.
Solution:
▶Replace the sealing ring.
Fault 7: The discharge size becomes larger
Cause:
▶The triangular belt on the transmission part is loose due to the long running of sand making equipment.
▶Feed size exceeds the limit.
▶Unreasonable impeller speed leads to low efficiency.
Solution:
▶You can adjust the tightness of belt.
▶Feeding in strict accordance with the feeding requirements of sand making machine
(if the feeding is too large, the equipment will swing too much; if the feeding is too small, the material can't be crushed sufficiently so that it is difficult to reach the qualified finished sand).
▶You can adjust the impeller speed until it reaches the standard.
Fault8: The machine sounds rise suddenly with a boom
Cause:
▶The bearings or gears go wrong.
▶Bolt looseness.
▶The wear parts is broken seriously.
Solution:
▶Check the bearings and gears whether are in good condition, repairing or replacing them in time
▶Fastening bolts.
▶Replace wear-part
Fault 9: Excessive idling resistance
Cause:
▶The material is blocked in the sealing cover of the bearing.
Solution:
▶Remove the clogging material from the bearing and check the corresponding device whether has other blockage.
Fault10: There is a clanking of metal in the sand making machine
Cause:
▶Some wear parts inside the sand making machine loose or fall off (such as bolts, lining plates, and impeller).
Solution:
▶The machine needs a complete inspection so that you can replace or maintain some related parts.
As we all know, sand maker plays an irreplaceable roles in sand making of various ores. It's currently the most effective, practical and reliable sand making equipment. The 10 faults listed above are often encountered in the production of sand making machine, in addition, if there are other unknown reasons for the failure in operation, don’t be careless, you should stop immediately to avoid any damage.
