Surfaces Designed for High and Low Friction

mechanisms it should be possible to find optimal surface designs to gain both low, stable and controllable friction and minimal wear. Designed tex- tures could then be optimized for a range of new applications. Surface design can also be utilized to increase the coefficient of friction. A high friction is desirable in numerous applications such as fixtures, cou-plings and bolted joints. …

CPE: Lesson 13. Principle of Size Reduction

For example, coarse crushers have size reduction ratios of below 8:1, while fine grinders may present ratios as high as 100:1. However, large reduction ratios, such as those obtained when dividing relatively large solid lumps to ultra-fine powders, are normally attained by several stages using diverse crushing and grinding machines.

reduction ratios is below 8:1 and in fine grinding it is more than 100:1. Solids are broken mainly by four different ways, which are used in size-reduction machines. They are (1) compression, (2) impact, (3) attrition, or rubbing, and (4) cutting. Examples are a nutcracker, a sledge hammer, a file, and a pair of shears. In these four types of processes, compression is used for coarse …
