Before starting, turn the rotor by hand, see if the operation of the paw, the hammer, and the rotor is flexible and reliable, whether there is a projection in the housing, whether the rotation direction of the rotor is the same as the direction indicated by the machine arrow. Flat airflow mill is simple, easy to manufacture due to flat air flow milling, easy to manufacture, so it is widely used.
Structure: Mainly composed of a crushing chamber, a nozzle port, a discharge opening, a gas flow outlet, a compressed air inlet, a grading area, and the like.
Working principle: Transform the compressed air or overheating steam into a high-speed airflow through the nozzle, when the material is sent to the pulverizing chamber by the feeder, a strong impact and dramatic friction make the material are pulverized Become a super fine product.
The power engine and grinding machine are smooth. Don't replace the pulley at will, so as not to exceed the speed, the crushing room burst, or the speed is too low, and does not affect the working efficiency of the pulverizer.
Airflow grinding should be idled 2-3 minutes after starting, there is no abnormal phenomenon before the feed operation. Pay attention to the working state of the pulverizer during the operation, and the feed is uniform, preventing the vehicle from clogging, and the operation is not overloaded for a long time. If there is vibration, noise, the bearing and body temperature is too high, the spray appearance should immediately stop the examination, and the troubleshooting will continue. With the development of society, in order to play a better role, some equipment has made great breakthroughs.
The airflow pulverizer has a good effect on the shredded target and accounts for special positions. During operation, Jet Mill should pay attention to certain operations and cannot meet production needs and overload. Therefore, we should pay attention to air flowing maintenance to ensure its efficiency.
Let us know the advantages of Jet Mill.
1. Non-heating, especially suitable for ultrafine powder-grinding thermal materials, in addition, while developing new materials while developing new materials, it also considers another form of cold air flow cooling mechanical crushing mode. . The feasibility of the pulverization performance and process of the mechanical crusher is compared, as in the actual large-scale production, mechanical crushers can solve many problems. Try to use mechanical crush, usually high energy Jet Mill.2. Pollution is small. Since the grinding principle is the collision of the material itself, it is compared to other grinding media relative to other pulverized forms, a method of blade or ball milling. Jet Mill is a minimal pollution, especially for pharmaceutical, food and other industries.
3, easy to clean, gas flow is smaller than the internal transmission of other ultrafine pulverizer. After the fluidized bed pulverizer compresses, after filtration, after drying, the fluidized ultrasonic air flow is introduced through the nozzle, so that the material is fluidized, and the accelerated material is integrated in several nozzles. The collision, friction, and cut the microcarriers of the particles.
After the pulverized material is conveyed into the impeller grading area, under the action of the graded wheel effort and fan effort, the coarse powder is separated, and the coarse powder returns to the crushing chamber according to its own gravity, and the qualified fine powder is Airflow enters the cyclone, fine dust is collected by the bag dust collector, and the purified gas is discharged from the air. In particular, the Spiral Jet Mill structure is simple, easy to clean, without dead angles, can be pulverized as a sterile drug.
