The medicinal ultrafine pulverizer is an extension of the traditional Chinese medicine coarse powder, but different from the ultrafine powder of other industries, it should pay attention to many aspects when pulverizing the traditional Chinese medicine. For example, the traditional Chinese medicine uses complex parts, including flowers, leaves, roots, stems, and whole plants. The properties of different parts vary widely. From the cell level, the layers from the outside to the inside, such as the cork layer The cortex, phloem, forming layer, xylem, and rays are composed of different types of cells, and their constituent cells such as parenchyma cells, stone cells, ducts, wood fibers, and cork cells have different wall breaking properties. Another example is that different varieties of Chinese medicinal materials have different properties, such as the quality of Panax notoginseng, the softness and stickiness of Polygonatum sibiricum, and the fibrosis of Astragalus membranaceus. The homogeneity of Chinese medicine ultrafine powders other than Panax notoginseng needs to be further studied from different ultrafine pulverization techniques, evaluation indicators, and medicinal materials with different properties. ,
The fineness adjustment method of medicinal ultrafine grinder. Under normal working conditions, the factors that affect fineness are the air volume, the speed of the classification wheel and the feeding amount, and the degree of wear of the wearing parts. When the fineness is too thick: if the component is the largest, first reduce the feeding amount, and then increase the frequency of the classification wheel; if it is not enough, close the small air volume (the butterfly valve on the high-pressure air pipe). Repeatedly adjusted in this way, the medicinal ultrafine pulverizer finds and meets the fineness requirements and is the control point of the optimal output. When the fineness is too fine: first increase the air volume, if the air volume is the maximum, reduce the frequency of the classification wheel and increase the feed volume after the current drops. Repeated adjustments in this way to find and meet the fineness requirements are the control points for the best output.
Before the medicinal ultrafine grinder is inspected, the newly installed equipment will inevitably leave foreign bodies such as iron nuggets, welding heads, and welding slag when the equipment is in place and connected to the warehouse. Without the fan and the main motor, Open the impurity removal plate under the feed port, and let the impurities and washing materials drain out from below. After the end, open the ultrafine powder observation door, check whether there are impurities in the crushing disk, and check whether the gap between the classification wheel and the upper end is about 0.5mm. After the medical superfine crusher is debugged, the equipment is powered on after everything is normal. Set the parameters of the two frequency devices of the ultrafine powder feeding motor and the classification motor. Check the motor rotation direction. Adjust the pulse width and clearance of the solenoid valve of the dust collector, and check whether the solenoid valve is blowing normally. Check if the air-closing device is leaking. You can use your hand or fine powder to place it at the interface for suction. If necessary, seal it. After everything is normal, the subsequent startup sequence is: open the classification wheel, set the frequency to a high frequency (35HZ), start the high pressure fan (after normal startup)-the main motor (after normal startup)-turn on the feeding motor to check the main motor current (Do not exceed the rated current of the main motor). At this time, samples are taken in the finished product area to check the fineness of the finished powder. When the fineness exceeds the index, the speed of the classification wheel can be adjusted downward. Each time the rotation speed of the classification wheel is adjusted, the finished powder is sampled and tested at intervals. Whenever the rotation speed of the classification wheel decreases, the current of the host machine will decrease along with it. At this time, the feeding frequency can be gradually increased to increase the crushing output. At the same time, adjust the opening range of the high-pressure fan damper. Detecting the current of the high-pressure fan of the medicinal ultrafine grinder should not only ensure a certain air volume, but also allow the fan to work normally for a long time. If the output and fineness cannot be achieved due to material differences, the rotation direction of the classification wheel can also be the same as the rotation direction of the host. Other debugging methods are the same as above.
