Æ 1.02 Grinding Methods Barista Hustle

Listen to 2009 World Barista Champion Gwilym Davies narrate this lesson . Grinding is the process of applying stress to a material to break it up into smaller particles. Two types of stress are applied during grinding: compression, in which the material is pressed against a surface, and shear, in which force from two different directions is applied to different parts of the material.

Design and dynamic behavior of large Ring Motors for

Large grinding mills are driven by Gearless Drives, with the Ring Motor as its main component. The Ring Motor is the stress level is low due to the high stiffness of the structure. The anchor bolts and shear pins are veri-fied for allowable stress values. 4.2 Air Gap Deformation The deformation of the stator iron core and the related
