How to adjust the fineness of the finished product when the small air flow crusher is processed?
Shandong AlPa Powder Technology has laminated two years, successfully completed the special ceramic vertical grading wheel of lithium-electric positive electrode materials with a diameter of 600. Can be used with airflow classifiers. Compare the "ceramic horizontal grading wheel", successfully solved a series of problems such as adhesion, not fine, and unsteady. Shandong ALPA-developed lithium-eM positive material special ceramic vertical grading wheel can strictly control the iron content during operation, the grading is accurate, and the finished product is freely adjusted.
As an emerging small airflow pulverizer, it is currently very popular. It has been widely used in a variety of industries, and the small airflow crusher has been very good at Chinese medicine. It can be said that it should be worn, because it can put traditional Chinese medicine Materials from larger size to 200-3000 destinations, greatly increases some of the precious, rare herbal materials, making the human body more easily absorbed. So how to adjust its fineness when a small air current pulverizer is processed? Let's take a look.
Small airflow pulverizer fineness adjustment method, small airflow pulverizer In normal operation, the factors affecting fineness, the speed and feeding amount of the grading wheel and the amount of feeding The degree of wear of the part. When the fineness is thick: If the component is the largest, the amount of feed will be reduced, and the frequency of the high classifier will be adjusted; if it is not reached, it will close the air volume (the butterfly valve on the high pressure wind tube). Such repetitive adjustments, small airflow pulverizer finds and reaches fineness requirements and is the control point for optimal yield. When the fineness is too thin: first increase the air volume, if the air volume is the maximum, the amount of feeding is increased after the frequency of the classification wheel is lowered. This is repeatedly adjusted, finding and achieving the fineness requirements and the control point for optimal yield.
Small airflow crusher checks, newly installed equipment, when the equipment is in place and with the warehouse, it is inevitable that foreign matter such as iron block and welding head, welding slag, without opening the fan and the main motor Turn on the feed opening to remove the blade, let the impurities and the washing materials are discharged below. After the end, open the ultrafine powder observation door, check if there is impurities in the pulverization plate, check whether the grading wheel and the upper clearance are about 0.5mm. Debugging of small airflow pulverizer, after everything is normal, the power is started. Parameter settings for both ultrafine powder feed motors and grading motors. Check the direction of rotation of the motor. Adjust the dust collector solenoid width and gap, check whether the solenoid valve is blown normally. Check the shutterNo, there is a leakage, you can use your hand or fine powder to have a feeling of breathing in the interface, if you have a sealing treatment. After everything is normal, the sequence of boot in the future is: open-grade wheel, set the frequency at a high frequency (35 Hz), start the high pressure fan (after starting normal) - the main motor (after starting) - open the feed motor to view the main motor current (Do not exceed the rated current of the main motor). At this time, the finished powder fineness detection was sampled in the finished area. When the fineness exceeds the indicator, the hierarchical rotation speed can be adjusted downward. Each time the speed of the graded wheel is adjusted, the finished powder is sampled for a period of time. Whenever the speed of the hierarchy is lowered, the host's current will decrease, and the feed frequency can be gradually increased to increase the pulverization yield. At the same time, regulate the high pressure fan damper opening amplitude. Detecting the current of a small airflow pulverizer high pressure fan, it is necessary to ensure a certain amount of air, but also to work properly for a long time. If the amount of production and fineness is not reached due to material differences, the grading wheel rotation direction can be the same as the direction of rotation of the host. Other commissioning methods are the same.
The above can be seen that the small airflow pulverizer is mainly to adjust the fineness of the finished product by adjusting the grading wheel speed and the feed speed. In fact, the user can help the equipment production in addition to the adjustment fineness. Manufacturers, general small airflow crusher manufacturers have professional after-sales teams, can provide online technical consultation 24 hours.
Currently, artificial intelligence and Internet of Things have been more and more fields, and AlPa Powder Technology is an industrial powder equipment manufacturer that has always adhered to technological innovation, in artificial intelligence and I have also explored the application of the Internet of Things.
