Ball Mill: Operating principles components Uses

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size The large balls tend to break down the coarse feed

Light and the laboratory mouse

Although laboratory mice are exposed to a very different visual environment than their ancestors studies on the eyes of inbred strains have shown no differences in retinal anatomy and visual pigment expression compared to wild mice (Shupe et al 2006) Anatomically the mouse eye is broadly comparable to that of most other vertebrate species with a cornea and lens that refract light to form
