面对种类众多的中药超微粉碎机产品，如何选择合适的机型成为广大客户非常关心的问题，由于各型超微粉碎机的粉碎原理不同再加上粉碎物料的性质更是多种多样造成选择粉碎机时候的困难，如何选择超微粉碎机那么我们必须最先了解的是超微粉碎机的定义，从其定义出发选择机型也许是不错的途径。
In the face of numerous kinds of traditional Chinese medicine ultrafine mill products, how to choose suitable models become a vast number of customers are very concerned about the problem, because each type superfine disintegrator to the crushing principle of different plus grinding on the properties of the material is varied by selection disintegrator when difficulties, how to choose the ultra mill then we must first to understand the definition of ultrafine pulverizer, from the definition of models may be a good way.
超微粉碎是近20年迅速发展起来的一项高新技术，能把原材料加工成微米甚至纳米级的微粉，已经在各行各业得到了广泛的应用。鉴于粉碎是中药生产及应用中的基本加工技术，超微粉碎已愈来愈引起人们的关注，虽然该项技术起步较晚，开发研制的品种相对较少，但已显露出特有的优势和广阔的应用前景。
Ultrafine grinding is a new technology developed rapidly in recent 20 years. It can be used to process raw materials into micron or even nanometer scale. It has been widely used in all walks of life. In view of the crush is the production of Chinese traditional medicine and its application in the processing technology, ultra-fine pulverization has increasingly attracted people's attention, although the late start, development is a relatively small species, but has shown a unique advantages and broad application prospects.
超微粉碎技术是粉体工程中的一项重要内容，包括对粉体原料的超微粉碎，高精度的分级和表面活性改变等内容。据原料和成品颗粒的大小或粒度，粉碎可分为粗粉碎，细粉碎，微粉碎和超微粉碎，这是一个大概的分类。值得注意的是，各国各行业由于超微粉体的用途，制备方法和技术水平的差别，对超微粉体的粒度有不同的划分。
Superfine crushing technology is an important content in powder engineering, including the ultra fine grinding of powder material, the high accuracy of classification and the change of surface activity. According to raw materials and finished particle size or particle size, crushing can be divided into coarse crushing, fine crushing, micro grinding and ultra fine crushing, which is a general classification. It is worth noting that the use of various countries in various industries because of the use of ultrafine powder preparation methods and technical level difference, the size of the ultrafine powder have different division.
超微粉碎机一般为无筛式粉碎机，粉碎物料粒度由气流速度控制，粉碎粒度要求95%通过0.15mm（100目），一般用于特种水产饵料或水产开口饵料，超微粉碎通常由超微粉碎机、气力输送、分级机配套来完成。原料的粉碎粒度非常细，可能显示出意想不到的特性，但也带来了比较多的问题，如静电吸附，物料的流动性差，粉碎消耗的能量大，提高了生产成本，对加工操作的影响比较大，这些不利影响可以采取不同的方法加以克服（如改变饲料加工工艺）。
Ultra mill generally without sifter crusher, crushing particle size by the airflow speed control, particle size of 95% by 0.15mm (100 mesh), generally used for special aquatic feed or aquatic feed opening, superfine grinding usually by the ultra mill, pneumatic conveying, classifier to complete. Raw material crushing grain size is very fine, may exhibit unexpected characteristics, but also brought more problems, such as electrostatic adsorption, poor flow of materials, crushing energy consumption and improve the production cost, relatively large impact on the machining operation, these adverse effects can take different approaches to overcome them (such as the change of feed processing).
超微粉碎通过对物料的冲击，碰撞，剪切，研磨，分散等手段而实现。传统粉碎中的挤压粉碎方法不能用于超微粉碎，否则会产生造粒效果。选择粉碎方法时，须视粉碎物料的性质和所要求的粉碎比而定，尤其是被粉碎物料的物理和化学性能具有很大的决定作用，而其中物料的硬度和破裂性更居首要地位，对于坚硬和脆性的物料，冲击很有效；而对中药材用研磨和剪切方法则较好。
Through the impact of the material, the impact of the material, collision, cutting, grinding, and other means to achieve the realization of. The crushing method of traditional crushing can not be used for ultra fine grinding, otherwise it will produce the effect of granulation. Selective crushing method shall be as crushing the material properties and the requirements of grinding more, especially shattered on the physical and chemical properties of the material has a great role in the decision, which material hardness and cracking is highest in the first place, for hard and brittle materials, the impact is very effective; of traditional Chinese medicinal materials by grinding and shearing method is better.
实际上，任何一种粉碎机器都不是单纯的某一种粉碎机理，一般都是由两种或两种以上粉碎机理联合起来进行粉碎，如气流粉碎机是以物料的相互冲击和碰撞进行粉碎；高速冲击式粉碎机是冲击和剪切起粉碎作用；振动磨，搅拌磨和球磨机的粉碎机理则主要是研磨，冲击和剪切；而胶体磨的工作过程主要通过高速旋转的磨体与固定磨体的相对运动所产生的强烈剪切，摩擦，冲击等等。
In fact, any kind of grinding machine is not only a kind of mechanism of grinding are generally consists of two or more than two kinds of grinding mechanism of combined grinding, such as airflow crusher is the material the mutual impact and collision crushing; high-speed impact crusher is impacting and shearing crushing effect; vibration mill, stirring mill and ball mill pulverizer theory is mainly abrasive, impact and shear; and working process of colloid mill mainly through the high-speed rotation of the grinding body and the fixed abrasive body produced by the relative motion of strong shear, friction, impact, and so on.
