What are the specific reasons for the unstable operation of the vertical shaft sand making machine?
1. The bearing temperature of the vertical shaft sand making machine rises
 
cause of issue:
①Dust enters into bearing parts of vertical shaft sand making machine;
②Serious bearing wear;
③The bearing needs lubricating oil.
 
Solution:
①Clean up the dust of vertical shaft sand making machine in time;
②Replace a new vertical shaft type sand making machine bearing;
③Add lubricant in time.
 
2. The discharge granularity of the vertical shaft sand making machine becomes larger.
 
cause of issue:
①The long-term operation of the vertical shaft sand making machine causes the V-belt of the transmission part to loosen;
②The feed size is too large;
③The impeller speed of the vertical shaft sand making machine is unreasonable and the efficiency becomes low.
 
Solution:
①Adjust the tightness of the V-belt of the vertical-shaft sand making machine or replace the V-belt;
②Strictly control the feed particle size of the vertical shaft sand making machine and feed in accordance with the standard;
③Adjust the impeller speed to reach a reasonable standard.
 
3. The operation of the vertical shaft sand making machine is unstable.
 
cause of issue:
①The wearing parts on the impeller are seriously worn;
②The feed size is too large;
③There are obstructions in the flow path of the impeller, which makes the feed material swing unevenly.
 
Solution:
①Check the vulnerable parts and replace them in time to balance the impeller;
②Strictly control the particle size of the feed, and cannot exceed the value allowed by the equipment;
③Check and take out the obstructions on the flow path of the impeller, and clean the crushing cavity frequently.
 
4. The bearing of the vertical shaft sand making machine is not flexible.
 
cause of issue:
The bearing seal cover of the vertical-shaft sand making machine is caused by materials entering the inside.
 
Solution:
Open the sealing cover and clean up foreign objects.
 
5. The vertical shaft sand making machine makes abnormal noises during operation.
 
cause of issue:
The connecting bolts, liners, impellers and other vulnerable parts inside the vertical shaft sand making machine are loose.
 
Solution:
Immediately stop the machine for inspection and re-install the loose parts.
