2. Compress die springs beyond design limits, causing premature failure. 3. Cause stripper interference with the radius blend on the punches, resulting in broken punch points and heads. Punch overentry also causes excessive galling and wear on the punch points. Stamping Terminology Punch Operation Punches perform many functions.

where η is the disc rotation rate (rpm), d is the disc diameter (m), and θ is the surface tension (N/m). The present work aimed to study the effects of melt flow rate, angular speed and diameter of the atomising disc, on the median particle size, production yield, apparent powder density, morphology and microstructure of zinc metal particles.
Granulation, also known as agglomeration, pelletization, or balling, is a "sizeenlargement process" of small particles into larger coherent and stable ... granulation must be recognized as an example of "powder particle design": ... In particular, the powder feed is fed to the disc, typically at the edge of the rotating granular bed ...

Disc Pelletizers. Disc pelletizers are a type of nonpressure (tumble growth) agglomeration equipment. In the world of agglomeration equipment, the pelletizer is often chosen for its ability to finetune the product size, the process of which is a combination of both science and art.

The powder acts as a perfect action amplification device." Bell rounded up the help of her animalloving friends who provided their own pets for the shoot. She recalls, "I had a great deal of fun deciding what color to use on what dog.
The covered distance used in the present formula was measured with the equation (2 x Π x R x Rotation x Test Timing), where R is the distance from the sample position to the center of the disc.
