Process Control Agent an overview . A process control agent (PCA) is usually used in the process of mechanical alloying to avoid cold welding and bonding between the powder particles and the balls and the agglomeration of powder during milling, which is also noticeable for some alloy systems in the solid–liquid reaction ball milling process (Chen and Chen, 2006) Thus, an investigation into

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 mill consists of a rotating shaft with four attached parallel knives and a screen occupying one fourth of the 360 degree rotation. The mill is best used to crack whole grains with a minimum of "fines". It is not used as a final process for reducing the size of ingredients used in fish feeds. 2.5 Screening

Polymorph control of 5-fluorouracil (5-FU) was achieved by ball milling. Form II was synthesized through one-step neat grinding of raw 5-FU (RFU), and Form III (a new polymorph) was obtained by neat grinding RFU twice. Forms II and III of 5-FU were prepared separately through ball milling with different amou
