· The milling chamber is fed with an aqueous suspension of the drug, stabilizer, and the milling media or pearls rotate at a very high shear rate. This procedure can be carried out under controlled temperature. The friction and collisions among drug particles and pearls generate nanoparticles. Ease of scaleup and little batchtobatch variation are the advantages of media .
Highenergy ball milling. A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel ...
They consist of two to four blades that move in a screwlike manner, pushing the material parallel to the shaft for agitation. Propeller Agitators: It is an axial flow high performance mixer consisting of three blades mounted on the main shaft. They are ideal for mixing low viscosity and medium viscosity fluids and improving uniformity.
· Philosophy, 47, ) In this essay, I will seek to sustain the line of argument that, if Mill is to maintain the label of a true hedonist, his distinction between higher and lower pleasures is unjustified. Hedonistic title aside, it appears that the higher/lower pleasure distinction presents numerous other difficulties, both theoretically and ...
The ring die and rolls of a pellet mill exposed to high temperatures show metal fatigue and must be replaced often. The proper conditioning of dehydrated alfalfa meal will permit the manufacture of over 2 000 tons of pellets during the life of a standard die of 40 mm thickness. Overall, the texture of a soft feed mixture is changed from a meallike material with bulk density .
This type of homogenizer works by forcing cell suspensions through a very narrow channel or orifice under pressure. Subsequently, and depending on the type of highpressure homogenizer, they may or may not impinge at high velocity on a hardimpact ring or against another highvelocity stream of cells coming from the opposite direction.
· 1. It produces very fine powder (particle size less than or equal to 10 microns). 2. It is suitable for milling toxic materials since it can be used in a completely enclosed form. 3. Has a wide appliion. 4. It can be used for continuous operation. 5. It is used in milling highly abrasive materials. Disadvantages of Ball Mills 1.
· 1. Introduction. Protein powders can be used in a variety of different dosage forms, including pulmonary drug delivery,,, embedded in matrices for sustained parenteral release, and for intradermal vaccination,, .Another promising approach is their use as suspensions in nonaqueous liquids for subcutaneous administration,, .Potential suspension vehicles .

· Due to the high velocity of the compressed air flow, there is flowdependent pressure drop between the receiver and load (appliion). Hence the pressure in the receiver is always kept higher than the system pressure. At the appliion site, the pressure is regulated to keep it constant. There are three ways to control the local pressures which are given below.
· First, aqueous suspensions of wt % of palygorskite were prepared at room temperature by adding the desired amount of clay powder into distilled water and stirring at 200 rpm using a magnetic stirrer. After this, the chemical dispersant was added at a concentration of wt.%, under constant mixing.

Germany) and NS 100 1L‐panda 2K high pressure homogenizer (NIROSUAVI., Parma, Italy). Nimodipine nanosuspensions were prepared by using high pressure homogenizer. Nimodipine coarse powder was first disintegrated into microparticles by using fluid jet mill technology. The nimodipine suspension was then
