Crushing is a very important link in the process of pharmaceutical production. In recent years, with the continuous development of China's pharmaceutical industry, the crushing machinery industry has developed rapidly, but the traditional crushing machinery has gradually exposed some deficiencies in the use process. There are several types of jet mill, including flat jet mill, fluidized bed jet mill, circulating pipe jet mill, jet mill and target jet mill. Among these types of jet mill, flat jet mill, fluidized bed jet mill and circulating pipe jet mill are widely used. There are some limitations in the particle size, powder yield, powder recovery and the preservation of effective ingredients. In this environment, the airflow pulverizer technology will provide a new way for the development of superfine Chinese medicine powder with better efficacy and better varieties p>
When the gas passes through the charging ejector, the crushed raw materials enter the crushing chamber. There are several crushing nozzles around the crushing chamber, which spray supersonic air flow, so that the materials are crushed by the high-speed impact of air flow and the collision and friction of materials. The grading pipe separates the coarser particles, and the coarse particles are returned to the crushing chamber for further crushing. After the internal closed loop crushing, Uniform distribution (j) can be obtained at the outlet ū n yú n) Superfine powder. After using the jet mill for a long time, we need to clean it. Before cleaning the air flow pulverizer, it should be disassembled. The specific disassembly techniques (Skills) are as follows: 1. Cleaning: turn off the main power supply of the equipment, and then use a brush to remove the residual dust (form: solid particles) in the machine. Pay attention to cleaning layer by layer. The coarse and fine mixed powder of the air flow pulverizer is driven by the negative pressure air flow through the turbine classification device set on the top. The fine powder is forced through the classification device, and is collected by the cyclone collector and the bag type dust collector. The coarse powder is thrown to the four walls by gravity and the centrifugal force generated by the high-speed rotating classification device and settles back to the crushing chamber for further crushing. 2. Dismantle the feeding hopper: first remove the four bolts on the base (composition: head and screw), and then take down the feeding hopper. 3. Remove the screen: open the door of the airflow crusher, and then take out the screen. 4. Remove the movable gear: loosen the fastening nut first, and then separate the movable gear from the main engine shaft. After that, remove the movable gear and place it safely. 5. Remove the fixed gear: remove the screw and then the fixed gear. Take care when disassembling the air flow crusher to avoid damaging parts or the machine body due to excessive action. By changing the ordinary air in the air source part into inert gases such as nitrogen and carbon dioxide, the air flow crusher can become an inert gas protection device, which is suitable for the crushing and grading processing of flammable, explosive and oxidizable materials p>
