The average high-quality feed pellet made for poultry, swine, and beef, high in cereal grains, becomes mushy within minutes after immersion in water. There is evidence that coarse-textured feeds, water soluble, and hygroscopic ingredients weaken pellet structure in water, allowing components to separate and making the feed only partially accepted.

• Milling beakers and milling balls should be of the same material. At least, the material density of the milling beaker should be higher than that of the milling balls. • The applied material should be chemically inert towards the reaction mixture. For most applications in organic synthesis, including catalysis, ceramic materials (e.g. ZrO 2

Addition of a stable, high-quality DC amplifier and voltage regulator to the circuit (see figures 4 and 5) improves the transducer output and allows the device to operate over a wide range of supply voltages.

The high-density chemical elements usually have high melting points. For the aforementioned elements with relatively high densities, the melting point of W (3695 K) is significantly higher than that of the Mo (2896 K), Nb (2750 K) and V (2175 K). In this regard, fabrication of high-density HEAs by melting and casting is very challenging.

This causes the flocking fibres to penetrate and imbed in the adhesive at right angles to the substrate. This forms a high density uniform flock coating. Controlling the electrical field by increasing or decreasing either the applied voltage or the distance between the electrodes and the substrate controls the speed and thickness of the flocking.

Specific gravity —the specific gravity of the milling media also plays a very important role in the milling process. It is well known that balls with high density and large diameters would give excellent results due to the expected generation of high impact forces applied on …
