Particle Size Reduction - Contract Particle Size

For extreme fineness requirements Particle Size Reduction Services include the use of air micronisers or batch ball mills with ceramic liners and media for iron free grinding in both wet and dry states. Wet grinding can be followed by filtering and tray drying to produce dry powders after dissagglomeration. All the Contract Particle Reduction Services can be followed by further in house


· BALL MILL Principle: The ball mill works on the impact between the rapidly moving ball and the powder material, both enclosed in a hollow cylinder. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Fig: Ball mill 13 14. Working: The drug is filled into cylinder 60% of the volume. A fixed number of ball

Practical 1 : Ball Milling | TF Lab 1

· In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length

Size Reduction - an overview | ScienceDirect Topics

The size of the milling media (typically 20:1 for ball:powder diameter) also influences size, morphology and microstructure of the powder. To produce fine powders, it is recommended to mill in several steps while reducing successively the milling media size, as one milling step usually induces a particle size reduction of about factor 10.
