After reviewing the information presented in Table 1, Table 2 and Table 3, it can be inferred that a planetary ball mill is the type of mill most commonly used in all three types of drug formulations. Planetary instruments have vessels placed inside a rotating disk and can induce high energy to the powder to prompt changes.

The speed of rotation is very important. At a low speed, the mass of balls will slide or roll over each other and only a negligible amount of size reduction will occur. At a high speed, the ball will be thrown ...
WhatsApp: +86 18203695377Groove or slot milling. Groove or slot milling is an operation in which side and face milling is often preferred to end milling. Slots or grooves can be short or long, closed or open, straight or nonstraight, deep or shallow, wide or narrow. Tool selection is normally determined by the width and depth of the groove and, to some extent, length.
