Raymond Mill Fineness Non-Compliance Reason

Raymond mill during operations may be some failures that some users to understand and exclusion, and some failures, some users do not understand, and which resulted in the user difficulties, this paper to address these issues a brief analysis.

Raymond mill Common faults are many, this article focuses on the following three, and each failure to resolve will be equipped with the relevant methods cause analysis and failure to exclude specific troubleshooting and analysis, and troubleshooting as follows.

Fineness of the finished material is not up to the machine, too thick or too thin. Causes of non-compliance of the fineness of the finished material, there are three, either because the speed of improper separator, or too fast, you want to but slowly, too quickly will make the finished material through fine, the speed is too slow will make the finished material through rough, then you need to check the control separator speed of the motor voltage, adjust the voltage.

There may be a separator blade wear Raymond mill is serious, would not achieve the grading effect, will cause the product fine through coarse, then need to replace the separator off small fan blades and appropriate to address the finished product into the wind the crude material had a problem. When the intake air volume fan can also cause this situation is not the time, then need to determine the size of the air intake volume, the product needs to improve fine through the thin air intake volume, otherwise reduce the amount of wind.

Raymond mill will appear host current rise and fall fan current phenomenon, caused major reason for this phenomenon is the feed inlet feed excess, causing duct blockage, material accumulation, poor exhaust pipe, and because Raymond grinding mill production system is a closed loop system, so the system will host circulating air heating current rise in the temperature of the machine rises, the fan current decline. For this failure discharge method to reduce the amount of...
