During the pharmaceutical process, the ultra -fine powder obtained by microcrystalline and ultra -fine crushing is generally through the process of controlling crystals. If we want to support the crystals, then we must pass the small airflow through small airflows. The crusher is implemented. The characteristic of a small airflow crusher is that it is the advantages of the fineness and quality of the ultra -fine drugs. It is also very suitable for the ultra -fine crushing of drugs. In daily life, the most common mechanical shocking machine, ball mill, vibration grinding, and mixing grinding. The two -way rotating ball mill, as well as the airflow crusher.
There are many characteristics of small airflow crusher in the drug. At present其粉碎与其他的粉碎机工作原理是有所不同的,而且小型气流粉碎机产出比比较匀称,颗粒分布范围也是比较广泛的,而且平均颗粒度是比较细腻的,在进行粉碎的过程中由于The effect of rotating the heart of the high -grade machine gas flow is finally automatically graded, so the granular distribution range of the product obtained is relatively narrow, and the average particle size is relatively fine D50 generally between 5 ~ 10 \u0026 mu; M.
The shape of the small airflow crusher is better, and the purity of the product is also relatively high. It is also relatively regular, the dispersability is better, and the mechanical wear of mechanical wear is relatively small during the crushing process, and the purity of the product is relatively high.
Small airflow crusher is very suitable for use and low -melting point, heat -sensitive drugs. The airflow crusher mainly uses compressing air as power. High-speed jet air flow generates a Jiao ear-Thomson effect. The airflow collides with thermal insulation at the nozzle, which reduces the temperature of the crushing system, offsets the heat generated by the collision and friction of the drug. The temperature can reach minus dozens of degrees Celsius, so it is suitable for preparing low melting points and thermal drugs.
Although the equipment of small airflow crushing machine is said to be better because the closed nature is relatively good, the yield of the product is relatively high. There will be no leaks, so there is no major pollution for the environment, and it can be operated in a state of sterile. Some people already know how to do it for its operations. During the crushing process, it is continuous. It uses closed circulatory system technology and automated control technology, and the overall operation is relatively simple.
Small airflow crusher can achieve crushing, mixed, and drying online preparation, or it can be modified by synchronous targeting drug powder. Granges cover and surface modification.
This small airflow crusherThe biggest disadvantage is that the utilization rate is low, the overall energy consumption is relatively high, and the production cost is also relatively high. During the crushing process, the momentum of the power of the air;The kinetic energy is crushed to the particles.With the progress of this process, the degree of particle is also getting smaller and smaller, and the more difficult to make the dynamic energy of the momentum, the more difficult it is to perform, so it is not suitable for low value -added products.② During the crushing process, high -speed air flow easily takes away volatile components, causing losses of active ingredients.
