超微粉碎机的粉碎方式怎么选择才好?

超微粉碎机在外界激振力的作用下,磨介作时而散开、时而聚合的抛掷运动。磨介自身做同向自转,磨介群做公转。内外层磨介不断交换位置,两两磨介不断冲撞、挤压剪切物料,使物料被挤破剪断。颗粒由大到小不断被破碎。在破碎过程中,较大颗粒先受力,先被破碎。
Under the action of external exciting force, the grinding medium sometimes disperses and sometimes aggregates. The grinding medium itself rotates in the same direction and the grinding medium group rotates in the same direction. The inner and outer grinding media constantly exchange positions, and two grinding media constantly collide and extrude the shearing material, which causes the material to be crushed and cut. Particles are constantly broken up from large to small. In the process of crushing, the larger particles are first subjected to force and then crushed.
由工作原理可知,植物细胞群组成的颗粒,无论是由大细胞组成的颗粒,还是由小细胞群组成的颗粒,只要其整体尺寸相当,其受挤压,冲击的机会是均等的。即在药材的粉碎过程中,不论大细胞群还是小细胞群只要其整体尺寸相当其被粉碎的机率是相同的。
It can be seen from the working principle that the granules composed of plant cell groups, whether composed of large cells or small cell groups, have equal chance of being squeezed and impacted as long as their overall size is equal. That is to say, in the process of crushing medicinal materials, as long as the overall size of large or small cell groups is comparable, the probability of crushing is the same.
超微粉碎机通过对物料的冲击,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。

Ultra-micro grinder is realized by means of impact, collision, shearing, grinding and dispersion of materials. The traditional crushing method can not be used for superfine crushing, otherwise it will produce granulation effect.
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;
When choosing the crushing method, it must depend on the properties of crushed materials and the required crushing ratio. Especially the physical and chemical properties of crushed materials play a decisive role. The hardness and rupture of materials are the most important, and the impact is very effective for hard and brittle materials.
而对中药材用研磨和剪切方法则较好。
The method of grinding and shearing is better for Chinese medicinal materials.
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;
In fact, any kind of crushing machine is not a simple crushing mechanism. Generally, two or more crushing mechanisms are combined to crush. For example, the airflow crusher crushes by the impact and collision of materials.
超微粉碎机是冲击和剪切起粉碎作用;
Ultra-micro grinder is impacted and sheared to grind.
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。
The grinding mechanism of vibration mill, stirring mill and ball mill is mainly grinding, impact and shearing, while the working process of colloidal mill is mainly through the strong shearing, friction and impact produced by the relative motion of high-speed rotating grinding body and fixed grinding body.
