Solutions for fractionating and chopping of particles. The term 'sieving' describes the separation of undesirable fine and coarse particles. For sieving, a vibration sieve is typically used. For homogenizing granules, we use grinders that work according to the principle of rotor sieves for homogenization. Coarse particles are reduced to the ...

The Operating Principal. P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process material itself.

Jet mills are achieving a size reduction by accelerating the product to be milled and throwing it either against a static target, either against another flux of accelerated particles To achieve this purpose, speed of up to 250 m/s must be reached in order to give enough energy to the particles to break them at the impact.

As the name suggests, wet milling involves size reduction of drug particles suspended in a liquid medium that may be aqueous or non-aqueous in nature. Wet milling is particularly suited for potent drugs and drugs which possess high residual moisture contents (>50% moisture) because dry milling may be problematic for drugs of this nature.

These materials are often spray dried or atomized after going through a wet milling process. Although this creates a fine, dry powder, the material can agglomerate. Small "satellites" can form around a larger particle, creating flowability issues or quality distortions in extrusion and additive manufacturing production.

Wet-milling is a method of reducing the particle size of an API in suspension. It can readily achieve particle sizes (10-15 microns of mean volume) near to those of jet-mill micronization – without many of the disadvantages. Some of the advantages of wet-milling are: Protects Temperature Sensitive Compounds

In this paper, the feasibility of using a wet abrasive jet machining process (wet AJM) to produce smooth and crack-free micro-features on RB-SiC was investigated for the first time. Three commercial abrasives were employed to test the machining responses. The hardness of abrasive was found to be critical and dominates the machinability of RB-SiC.

Jet mills. Until the introduction of jet mills in 1936, dry grinding in the subsieve range of 625 mesh (20 microns) to 2,500 mesh (5 microns) was impractical. To create fine particles with a narrow PSD, manufacturers previously had to mill the material, sieve out the oversized particles, and re-mill. The process was long, expensive, and ...

Wet Milling. The most common method of producing nanoparticles, wet milling is a more effective milling technique than the well-known dry milling. Media milling is known as the 'classical' wet milling technique; this process treats a dispersion of concentrated drug in an aqueous or non-aqueous liquid medium with milling balls.
