Do you need to be cautious! Pay attention to these when the ultrafine pulverizer is operated

  Ultrafine pulverizer before testing everything is normal, and the power is started. 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. Check the direction of rotation of all motors. Parameters inspection settings for the feeder of the ultrafine pulverizer and the variable-frequency driving, check the vaccuition, contactor, the air relative corresponding to the motor, Whether the current relay adjustment is appropriate. Return all lines all over again. Check if the solenoid valve is blown normally, adjust the dust collector solenoid valve application range: electron, optical, electromechanical, medical, etc. and blow interval.

  Check if the cleaning of the turbine under the brake dragon has a leakage, you can use your hand or fine powder to have a feeling of breathing at the interface, if you have a sealing treatment (chǔ lǐ). After all of the above tests are normal, prepare the production (Product). Ultrafine pulverizer debugging work procedure, at which time the finished powder fineness detection was sampled in the finished area. The gas generating pulverizer material enters the cylindrical pulverizing chamber through the feed opening, and is crushed along the grinding rail, and the pulverization is achieved. Airflow pulverizer and cyclone separator, dust collector, and airplane set into a set of pulverization systems.

  After the compressed air is dried, it is sprayed into the pulverizing chamber by the Lavar nozzle, and the material is repeatedly collided with the intersection of the multi-high pressure airflow. The crushing material is pulverized after the fan pulling force Airflow movement to the grading area, under the power of high-speed rotation, the thick centrifugal force generated by the high-speed rotation, the fine particles that meet the particle size requirements are collected by the grading wheel into the cyclone and the dust collector, and the crude particles drops to the pulverizing region to continue pulverization. .

  When the fineness exceeds the indicator (Target AIM), the hierarchical rotation speed can be adjusted downward. Each time the speed of the graded wheel is adjusted, the fineness of the finished powder will be sampled at a period of time. Whenever the speed of the hierarchy is lowered, the current of the host will also decline, at which time the feed rate can be gradually increased to increase the pulverization yield.

  Adjust high pressure fan at the same time (DRAUGHT FAN's damper opening, detecting the current of the high pressure fan, must ensure a certain amount of air, but also to work properly for a long time. If the cause of material difference is not required, the yield and fineness may not be required, and the direction of the hierarchical wheel rotation may be the same as the direction of rotation of the host, and other debugging methods are the same.
