10 Leading Faults And Solutions Of Sand Making Machine

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.
