Ultrafine pulverizer debug theory

　　In the ultrafine pulverizer process, the material is typically pulverized with a hammer pulverizer (such as a tortoise material). The main applied pulverization mechanism determines the characteristics of a wide range of applications, high finished products, typical materials are: super hard diamond, silicon carbide, metal powder, etc., high purity requirements: ceramic color, medicine, Biochemical, low temperature requirements: medicine, PVC. By change the ordinary air of the gas source to nitrogen, carbon dioxide gas, etc., the unit can be made into an inert gas protection device, which is suitable for the pulverization classification of materials such as flammable explosive, easy oxidation. The main applied mechanism of ultrafine pulverizer determines its application range, high finished product, typical materials are: super hard diamond, silicon carbide, metal powder, etc., high purity requirements: ceramic color, medicine , Biochemical, low temperature requirements: medicine, PVC. By change the ordinary air of the gas source to nitrogen, carbon dioxide gas, etc., the unit can be made into an inert gas protection device, which is suitable for the pulverization classification of materials such as flammable explosive, easy oxidation. The ultrafine pulverizer is an apparatus for ultrafine pulverization of dry materials using air separation, heavy polishing, and shear. It consists of a cylindrical crushed chamber, a polishing wheel, a polishing rail, a fan, a material collection system, and the like. The material enters the cylindrical pulverizing chamber by the feed opening, and is crushed by the polishing wheel that is circumferential movement along the grinding rail, and dissensibly. The pulverized material brings out the pulverizer through the negative pressure air flow caused by the fan, into the material collection system, filtered through the filter bag, the air is discharged, the material, the dust is collected, and the pulverization is completed. When the sieve pore size of the pulverized selected, the material contains no more than 12% when the material is controlled in (1.0 to 1.5) mm, and then the ultrafine pulverizer is entered. The degaussing device must be installed during this process. The finished material uses a wind conveying system. In a wind conveying system, different types of ultrafine pulverizer uses a suitable pipe network management pipe diameter, elbow radius, brake dragon and dust collector. Among them, the smallest type of ultrafine powder (SWFL82A) is less than 350 mm in the wind tube, and the fan adopts a 9-19 transmitting D series high pressure fan.

　　The ultrafine pulverizer checks, newly installed equipment, when the equipment is connected and connected to the warehouse, inevitable residual iron blocks, welding head, welding slag, etc. Do not open the fan and the main motor, open the blade under the intake. Let the impurities and cleaning materials are discharged from below.After the end, open the ultrafine powder observation door, check whether there is impurities in the pulverization plate, check whether the gap between the classification wheel and the upper end is about 0.5 mm. After the device is debugged, everything is normal, turn on the power start device. Setting the parameters of the ultrafine powder motor and the grading motor. Check the direction of rotation of the motor. Adjust the pulse width and gap of the dust collector solenoid valve, check whether the solenoid valve injection is firm. Check if there is any air leak brake dragon, you can use your hands or fine powder interface with suction feeling, if you must have a sealing. After everything is normal, the latter start order is as follows: Open the grading wheel, set the frequency to high frequency (35 Hz), start the high-voltage fan (after normal startup) - Main motor (after normal startup) - Open the feed motor to check the master Motor current (do not exceed the rated current of the main motor). At this time, the fineness of the finished powder is tested by sampling in the finished area. When the fineness exceeds the indicator, the speed of the hierarchy wheel can be adjusted. Each time the speed of the hierarchy is adjusted, the finished powder is sampled and tested every other period of time. When the speed of the hierarchy is lowered, the current of the host will decrease, and the feed frequency can be gradually increased to increase the output of the pulverized output. At the same time, adjust the opening range of the high pressure fan damper. To detect the current of the high pressure fan, not only to ensure a certain amount of air, but also to work properly. If production and fineness is not reached due to different materials, the direction of rotation of the hierarchy can also be the same as the direction of the host. Other debugging methods are the same as those of the above methods.
