Laboratory Powder Milling Machine
Laboratory Powder Milling Machine is formed by impact, extrusion and friction of grinding ball when grinding materials. For example, we take a single particle as the object of study. When it is milled, it will be repeatedly affected by the above-mentioned stress, which makes the cracks or new cracks on the particles expand continuously, resulting in crushing or plastic deformation.
As the particles become smaller and smaller, the cracks on the particles become finer, the probability of crack occurrence of the minimum fracture stress decreases, and the grinding force increases to a state where the particles will produce plastic deformation, which makes it difficult to further grind the particles to a certain particle size. So it is the simplest and direct way to change the grinding time and speed, but it is not that the higher the speed is, the better it is, the longer the grinding time is, the finer the grinding is. The variety of materials can not be generalized. The best speed and grinding time need to be verified by experiments and actual use.
