How to select a crushing method of the ultrafine pulverizer
Under the action of the external excitation force, the grinding die is diffused, and sometimes the polymerized throwing movement. The grinding body is doing the same direction, and the grinding group is a public. The inner and outer surface of the inner and outer surface is constantly switching. The two and two grinding methods are constantly implicit, and the shear material is extruded, so that the material is squeezed. The particles are constantly pulverized by large to small. In the pulble process (guò chéng), larger particles are first force, first pulverized.
It can be seen from the working principle that the granules composed of plant cell populations, whether particles composed of large cells, or particles composed of small cell populations, as long as their overall size is equivalent, and the opportunity to be extruded and impact is equal.
That is, during the pulverization of the medicinal material, regardless of the large cell population or small cell population as long as its overall size is relatively pulverized. The ultrafine pulverizer is achieved by means of impact, collision, shear, grinding, dispersing of materials. Xiao Su Type Grinder is pulverized by the negative pressure air flow caused by the fan, and enter the material collection system. After filtering, the air is discharged, the material, the dust is collected, and the pulverization is completed. The main applied mechanism of ultrafine pulverizer determines its application range, high finished product, typical materials are: super hard diamond, silicon carbide, metal powder, etc., high purity requirements: ceramic color, medicine , Biochemical, low temperature requirements: medicine, PVC.
The extrusion pulverization method in traditional pulverization cannot be used for ultrafrite, otherwise the granulation effect will be produced. When the Xuanze is pulverized, the properties of the pulverized material must be derived from the required pulverization ratio, especially the physical and chemical performance (parameters of chemical reactions) of the pulverized material, and materials Hardness and Hardness and cracking are more primitive, for hard and brittle materials, the impact is effective; and the grinding and shearing methods for traditional Chinese medicine are better.
In fact, any crushing machine is not a simple kind of pulverization mechanism, which is generally united by two or more comminuted mechanisms, such as the airflow pulverizer is pulverized by the mutual impact and collision of materials; The ultrafine pulverizer is a shock and shear and pulverized effect; the graphics of vibration grinding, stirring grinding and ball mill is mainly grinding, impact and shearing; the Colloid's work process is mainly high.Strong shear, friction, impact, etc. generated by the relative movement of the speed rotating, the relative movement of the fixed (Fixed). Xiao Su Type Grinder is pulverized by the negative pressure air flow caused by the fan, and enter the material collection system. After filtering, the air is discharged, the material, the dust is collected, and the pulverization is completed.
