The purpose of this study was to investigate the influence of micronization technique on performance and stability of the model drug formulated in a suspensionbased pressurized metereddose inhaler (pMDI). The model drug, triamcinolone acetonide (TAA), was subjected to ball milling or airjet milling prior to formulation of the pMDI.
interchangeability make it easy for a single mill to produce a variety of results [4]. Some of the common techniques for size reduction are listed as follows: Multi Mill The Multi mill working principle involves a variable force rotate blades having both knife and sharp edges with validated screen size to reduce particle in a controlled manner.
The jet mill has no moving parts. Micronization is achieved by the passage of gases such as air or superheated steam through special nozzles in the mill to create high velocities which can exceed ...
Materials that degrade with heat or have low melt temperatures are a problem in hammer mills because of the heat generated in the 1936 the first commercially practical jet mill or spiral jet mill was introduced. This was the predecessor to our current MicronMaster® design. Up to that time, dry grinding in the subsieve range of 625 to ...
Spiral jet mill technology is recommended for target particle size distribution below 30 µm, while QMill technology or pin mill is suitable for PSD in the 30100 µm range. FPS offers a full range of equipment that ensures complete and safe micronization of powders of all types of materials.
"At Frewitt we have mastered the nano milling process and are proud of this accomplishment that pushes the boundaries of nano milling technology further," says Roy Housh, the company's director of sales. The technology Housh proudly refers to is the patented NanoWitt bead mill, which can be used to reduce micronsized powder down to nano ...
