Mathematical Model Ball Mill Ciclon. FOB Reference Price: Get Latest Price glass ball microscope replicas. I havent yet honed my lensmaking skills to resolve bacilli, spirilla, cocci, like he did, but diatoms look awesome through it I just twirl a glass thread in a flame to make the spheres, but I dont think I have the patience to do the polishing that he did.
The experiments of various authors confirm the laws of the process of milling in a drum-type ball mill, as derived from an analysis of the authors' proposed model. 2. The optimum control law found by analysis of the model is very similar to the well-known "Mekhanobr" principle.
