Is the pulverizing process of air flow pulverizer not smooth? Maybe it's because of these original Umico powder machinery

Airflow pulverizer is a kind of equipment with simple structure, stable operation and excellent crushing effect. The interior of the machine has been processed to achieve smooth surface, effectively solving the problems of rough inner wall, easy powder accumulation and difficult cleaning, and making chemical and food production more in line with national standards. Blocking is one of the common failures of the jet mill in use, which is mostly caused by improper operation. In addition, there are also the following reasons for blocking of the jet mill:

Problem 1: The fineness of the API synthesis is small, and the particles are fine. For example, when it reaches 10-20 microns or finer, the liquidity of the API is poor, As a result, the feeder can not feed stably and continuously, thus affecting the crushing efficiency and crushing particle size. For example, the feeding speed is set at 5 kg at the beginning, and may return to 3 kg, 2 kg, 1 kg in 1-2 hours, and then gradually slow down, or even no feeding is needed. Therefore, the feeding system should be designed carefully to ensure that a batch of materials can be crushed smoothly< Br/>Problem 2: Venturi plugging, which is a common problem in the API crushing industry. Due to the influence of solvents and impurities, the API will slowly connect a layer of film on the venturi hole when spraying materials through the venturi to the crushing disk, and then the film will become thicker and thicker until the venturi mouth is blocked and cannot be fed for crushing production. At present, only Qingdao Youmingke Company can solve this plugging problem, But the premise is that the materials must be tested to ensure that if a batch of materials is 9 kg, we will adopt the 9 kg solution to ensure that the materials will not be blocked under the premise of crushing 9 kg. If it is 20 kg, we will adopt another solution< Br/>Problem 3: The crushing disk is blocked. As time goes on, very hard agglomerates will form inside the crushing disk and stick to the crushing ring, resulting in smaller and smaller crushing space. Finally, the crushing disk will be blocked and cannot be produced. However, Qingdao Youmingke Air Flow Crusher has a special crushing solution, that is, the materials will stop agglomerating to a certain extent. At that time, there were other methods to prevent agglomeration< Br/>Question 4: Some companies use induced draft fan and pulse back blowing to collect materials. This structure will cause the materials to accumulate in the bottom cone after entering the bottom cone and will not go down, affecting the crushing process. Qingdao Youmingke air flow crusher is specially designed to avoid this phenomenon. Materials will fall directly from the inside of the filter bag to the outlet in the middle of the bottom cyclone, It will not cause the material to stick to the edge of the vertebral body, causing problems for customers. It also needs to add vibrators, and the effect is very poor. This structure is a disaster for finer materials. In addition, the dedusting mode of pulse back blowing will affect the pressure in the crushing disk and affect the stability of particle size< Br/>Qingdao Youmingke is the source manufacturer of air flow pulverizers in China. After years of technical upgrading and process improvement, Qingdao Youmingke air flow pulverizers have higher processing accuracy, higher efficiency, better stability, and lower equipment failure rate than similar equipment. As a large R&D and manufacturer of jet mill, Qingdao Youmingke said that the development direction of jet mill should be to increase output and reduce energy consumption. Only research and application of new equipment is the way for manufacturers to develop
