This machine is widely applicable to shut mineral sands when the concentrator forms closed loop process with ball mills, or it is used to classifying mineral sand or fine mud, and make particle size grading in the metal beneficiation process in gravity concentrator plant, and washing mud and dehydration in washing job. The machine has a simple structure, reliable operation, easy to operate. I'm here to introduce the inspection and preparation before classifier operation:
1. If the amount of oil in the reducer is sufficient.
2. If each open gear is refueled;
3. If the bearings crosshead is refueled;
4. If the motor bearings is added oil.
5. If various open gear mesh is good.
6. If all bolts and top wire are tightened;
7. If coupling is intact.
8. Whether the helical blade is fractured, if lining iron is worn out or shedding, and if blade bracket is severely deformed.
9. If the spiral tail is filed.

The above is a introduction on check and preparation before grading machine operation. If you would like to learn more about the grading machine, please continue to pay attention to us, and we look forward to cooperating with you.
Note on grader welding:
As a well-known Grader suppliers, we are committed to providing customers with the best product quality and service attitude, customer satisfaction is our biggest goal. Here the the grading machine welding Notes:
The classifier should be thoroughly cleaned before welding the parts to be welded.
Heat-welding is better than the cold welding Therefore, the major parts for welding, may try to use the heat welding (pre-heated to the weldment 100 to 700 ° C, and then welding).
When soldering, if conditions allow, you should use welding, which is beneficial for weld quality, and is conducive to the operation.
Electrode diameter and current size is depending on the thickness of the weldment, the surrounding temperature and welding location selection, the electrode model should be in accordance with the criteria of the weldment materials and related technologies.
Our company adheres to the business philosophy of "integrity, quality, efficiency, and continuing to pursue the goal of" professional services, standardized management, international quality "Seiko secret agents, customer first" as the eternal purpose, and to implement real action to win the trust of customers at home and abroad.
