Replace the bearing, replace or stretch triangle belt and chain. 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. . Replace the gear ring, hammer block, guide ring, hierarchical impeller, pulverization plate and pad. When a hammer is installed, apply 12.9 high-strength bolts and spring pads to fix the hammer. The time to add 2 to the 2nd pressure composite lithium-based grease in the butter gun bearing: the spindle bearing for 30 hours, the hierarchical bearing is 100 hours, the motor bearing is 400 hours. When checking daily, you should listen to the daily sound from the various parts of the machine, listen to the abnormal sound of the bearing portion, and pay attention to bearings, pulleys, temperature rise, etc. Before starting and startup, you should carefully check the reliability of triangular belt, chain tension and hierarchical coupling connection. Whether the fasteners are firm, reliable, loose, often keep the mechanical appearance clean. When regular inspections and repairs, the following items should be checked and replaced. 1 After removing the bolt from the host, the slope assembly is lifted and moved to the appropriate shelf so that the slope impeller does not impact the ground so that the slope shaft is not bent.
Ultrafine pulverizer process, the material is typically mixed with a hammer pulverizer after hyperbits, and the sieve is mixed in (1.0-1.5) mm after mixing with a hammer pulverizer. The material contains no more than 12% water content and then enters the ultrafine pulverizer. 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 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 tubeNetwork management pipe diameter, elbow radius, brake dragon and dust collector. When the device is commissioned, everything is normal, boot and start the device. 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. 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 to open the grading wheel, set the frequency to high frequency (35 Hz) to activate the high voltage fan (after normal startup) - the main motor (after normal startup) - Open the forward 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, it is necessary to ensure a certain amount of air, but also to ensure the normal work of the wind. 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.
