In order to run the air pulverizing production line safely, this paper must not be missed

In order to run the air flow comminution production line safely, this paper must not miss that the air flow comminution production line is a kind of equipment which uses high-speed air flow to realize the ultra-fine comminution of dry materials The utility model is composed of a pulverizing nozzle, a grading rotor, a screw feeder, etc The materials enter the crushing chamber through the screw feeder, and the compressed air is injected into the crushing chamber at a high speed through a specially configured supersonic nozzle The materials accelerate in the supersonic jet flow, and repeatedly impact and collide at the intersection of the nozzles to achieve crushing The crushed materials enter the classification chamber with the rising air flow Because the classification rotor rotates at a high speed, the particles are not only subjected to the centrifugal force generated by the classification rotor, but also to the centripetal force generated by the airflow viscosity When the centrifugal force is greater than the centripetal force, that is, the coarse particles above the classification diameter return to the grinding chamber to continue to impact and crush, and the fine particles below the classification diameter flow into the cyclone separator and capture with the air Gas is discharged from the induced draft fan Working principle of air flow crushing production line: When the air flow comminution production line system is started up, the inert gas is used to fill the system continuously to replace the air until the whole system reaches the value set by oxygen content test, and then the feeding material is automatically started to enter the comminution chamber of the comminution host The compressed inert gas is injected into the comminution chamber at a high speed through a specially designed supersonic nozzle, and the material is accelerated in the supersonic jet flow, and is under impact , collision to achieve crushing effect The crushed materials enter the classification chamber with the rising air flow for classification The fine particles meeting the requirements enter the classification wheel and are collected by the cyclone along with the air flow The materials that cannot enter the classification wheel return to the grinding chamber for impact pulverization, and the purified gas after filtering returns to the suction port of the compressor for recycling Precautions for use of air flow pulverizer production line (1) before use, check the integrity of all parts, whether the fasteners are loose, and whether the preparatory work before start-up is good enough to meet the start-up conditions, and start-up operation after confirmation; (2) the electric box and motor must be grounded (3) during the operation of the air flow crusher, it is strictly prohibited to touch the rotating parts, especially to reach into the discharge port at the lower end of the discharge valve configured for the cyclone and dust remover to prevent accidents; (4) if it is necessary to maintain and maintain the air flow crusher, it must be carried out under the condition of cutting off the power supply and closing the air source, and it is strictly prohibited to work with electricity and gas (5) the speed of impeller shall not exceed the specified value, otherwise the temperature will be too high and the impeller and motor will be damaged The above is today about the safe operation of the air flow pulverizing production line, this article must not miss all of the sharing, hoping to help you use this equipment in the future
