面對(duì)種類(lèi)眾多的中藥超微粉碎機(jī)產(chǎn)品，如何選擇合適的機(jī)型成為廣大客戶(hù)非常關(guān)心的問(wèn)題，由于各型超微粉碎機(jī)的粉碎原理不同再加上粉碎物料的性質(zhì)更是多種多樣造成選擇粉碎機(jī)時(shí)候的困難，如何選擇超微粉碎機(jī)那么我們必須最先了解的是超微粉碎機(jī)的定義，從其定義出發(fā)選擇機(jī)型也許是不錯(cuò)的途徑。
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年迅速發(fā)展起來(lái)的一項(xiàng)高新技術(shù)，能把原材料加工成微米甚至納米級(jí)的微粉，已經(jīng)在各行各業(yè)得到了廣泛的應(yīng)用。鑒于粉碎是中藥生產(chǎn)及應(yīng)用中的基本加工技術(shù)，超微粉碎已愈來(lái)愈引起人們的關(guān)注，雖然該項(xiàng)技術(shù)起步較晚，開(kāi)發(fā)研制的品種相對(duì)較少，但已顯露出特有的優(yōu)勢(shì)和廣闊的應(yīng)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.
超微粉碎技術(shù)是粉體工程中的一項(xiàng)重要內(nèi)容，包括對(duì)粉體原料的超微粉碎，高精度的分級(jí)和表面活性改變等內(nèi)容。據(jù)原料和成品顆粒的大小或粒度，粉碎可分為粗粉碎，細(xì)粉碎，微粉碎和超微粉碎，這是一個(gè)大概的分類(lèi)。值得注意的是，各國(guó)各行業(yè)由于超微粉體的用途，制備方法和技術(shù)水平的差別，對(duì)超微粉體的粒度有不同的劃分。
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.
超微粉碎機(jī)一般為無(wú)篩式粉碎機(jī)，粉碎物料粒度由氣流速度控制，粉碎粒度要求95%通過(guò)0.15mm（100目），一般用于特種水產(chǎn)餌料或水產(chǎn)開(kāi)口餌料，超微粉碎通常由超微粉碎機(jī)、氣力輸送、分級(jí)機(jī)配套來(lái)完成。原料的粉碎粒度非常細(xì)，可能顯示出意想不到的特性，但也帶來(lái)了比較多的問(wèn)題，如靜電吸附，物料的流動(dòng)性差，粉碎消耗的能量大，提高了生產(chǎn)成本，對(duì)加工操作的影響比較大，這些不利影響可以采取不同的方法加以克服（如改變飼料加工工藝）。
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).
超微粉碎通過(guò)對(duì)物料的沖擊，碰撞，剪切，研磨，分散等手段而實(shí)現(xiàn)。傳統(tǒng)粉碎中的擠壓粉碎方法不能用于超微粉碎，否則會(huì)產(chǎn)生造粒效果。選擇粉碎方法時(shí)，須視粉碎物料的性質(zhì)和所要求的粉碎比而定，尤其是被粉碎物料的物理和化學(xué)性能具有很大的決定作用，而其中物料的硬度和破裂性更居首要地位，對(duì)于堅(jiān)硬和脆性的物料，沖擊很有效；而對(duì)中藥材用研磨和剪切方法則較好。
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.
實(shí)際上，任何一種粉碎機(jī)器都不是單純的某一種粉碎機(jī)理，一般都是由兩種或兩種以上粉碎機(jī)理聯(lián)合起來(lái)進(jìn)行粉碎，如氣流粉碎機(jī)是以物料的相互沖擊和碰撞進(jìn)行粉碎；高速?zèng)_擊式粉碎機(jī)是沖擊和剪切起粉碎作用；振動(dòng)磨，攪拌磨和球磨機(jī)的粉碎機(jī)理則主要是研磨，沖擊和剪切；而膠體磨的工作過(guò)程主要通過(guò)高速旋轉(zhuǎn)的磨體與固定磨體的相對(duì)運(yùn)動(dòng)所產(chǎn)生的強(qiáng)烈剪切，摩擦，沖擊等等。
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.
