Effect of mill type on the size reduction and phase …

 · The stress mode that effects size reduction in the air jet mill (Fig. 2b) is mainly impact, by way of particle–particle and particle–wall collisions. The collision energy is created by the high speed flow of compressed air ( Neikov et al., 2009 ).

Enhanced Wet Milling Technology for API Size Reduction

API size reduction achieved a mean volume (mV) particle size of between 12 - 17 µm for compounds with typical starting PSD’s of between 84 - 179 µm. Increased tip speed achieved an additional 30 - 60% reduction of mV & d95 for a wide range of APIs – whether the starting crystals were needle, plate or block-shaped (see figures 1 through 3).

Size Reduction

A typical second-stage size reduction process will use a 3/4 to 1-in. screen to produce a mean particle size of 1/9 to 1/8 in. While conventional milling processes achieve the desired mean particle size, they often have wide particle size distributions, with a large percentage of undersized particle…

Particle size reduction by a hammer mill I: Effect of …

A new particle size reduction constant, k, is proposed as a result of a linear relationship between dx and output screen size, dss. As dss decreases, the PSD range of milled particles narrows; as mill speed increases (approximately 5000 rpm), dx decreases.

Air Classifying Mill for Particle Size Reduction

The internal air classifier continuously recirculates particles that are larger than desired back into the grinding zone ensuring an optimal final product particle size. When faced with materials that can be difficult to grind or that require a narrower particle distribution curve, the unique capabilities of the air classifying mill are often necessary.
