WhatsApp: +86 18838072829The principle of roller mill is based on the crushing or compressing mechanism which is created by stress. It crushes and grinds big materials into tiny particles. Pharmaceuticals need to be small and consistent for more be effectivity. So, this mill controls the size and uniformity of the particles.
WhatsApp: +86 18838072829Roller mills are used for crushing seeds prior to extraction. Advantages of Roller Mills 1. Produce more uniform, fewer fines, and oversized particles when it comes to product quality. 2. Generates less heat (0 3 0 C) unlike hammer mill that generates up to 10 0 C 3. Less moisture loss 4. Better work environment due to low machine noises level

WhatsApp: +86 18838072829Principle of Grinding for these mills are done by Attrition and Compression method. The grinding force are applied through the sets of rollers on to the material bed spread over the rotating grinding table. This causes attrition initially followed by compression from external grinding forces.
WhatsApp: +86 18838072829Principle of the Triple Roller Mill Operating on the principle of shear force, the threeroll mill contains three horizontally positioned rolls. These rolls rotate in opposite directions and at varying speeds relative to each other. This movement allows the mill to mix, refine, disperse, or homogenize viscous materials. Related: Construction:
