Discontinuous linear map - Wikipedia

We will find a discontinuous linear map f from X to K, which will imply the existence of a discontinuous linear map g from X to Y given by the formula where is an arbitrary nonzero vector in Y . If X is infinite-dimensional, to show the existence of a linear functional which is not continuous then amounts to constructing f which is not bounded.

Ball mill - Wikipedia

In case of continuously operated ball mill, the material to be ground is fed from the left through a 60° cone and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down (or drop down on to the feed), from near the top of the shell.

What Causes Cement Balls?| Concrete Construction Magazine

Cement has a high affinity for water. So upon contact with water, the dry cement powder acts like a sponge and globs up. The balls form as these globs roll against the inside drum surface. The key to prevention is to program a material-loading sequence that deposits the cement and the coarse aggregate into the drum at the same time.
