Trying to invent a pen that could write on leather, a tanner, John J. Loud, invented the first ballpoint pen and patented it in 1888 in America. This pen had a small steel ball placed so it could not fall out nor fall in but still rotate freely. This invention was not commercially viable and could not be used for writing because the patent ...

Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).

Invention can be understood as a process of discovery (Conley 317) and creation (Welch 169).* This can mean that you will discover something new about an existing idea or create a new way of look-ing at something.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
