Particle size reduction, or grinding, is a process to produce a polymer powder necessary for a particular industry or technology. This can be accomplished by starting with resin pellets or a powder that is ground to a finer powder. At Ancos, we can achieve a range of desired size distributions to meet specifications, from coarse to fine.

What is Centerless Grinding The complete guide to the

Oct 19, 2020 Centerless grinding is a process that has been a part of manufacturing for nearly 100 years. It helps solve one of the limitations of other types of turning machines such as lathes and mills. The process is better suited to deal with the limitations imposed on lathes and mills with respect to the size, material type, and finishes of different ...

A grinding unit was actually constructed and it was experimentally confirmed that the ball rotational speed can be controlled well by the shoe or regulator. Grinding tests were subsequently carried out and the obtained results indicated that the constructed grinding unit performed well on actual ball centerless grinding operations.

Superfine ground calcium carbonate GCC produced by carbonate minerals is a widely used inorganic powder material. In order to get a finer GCC powder with narrow distribution span, the effect of rotational speed and media density on ground GCC were studied by dry grinding GCC in a planetary ball mill under different rotational speed and various media density.

SIMULATION ON THE GROUND WAFER SHAPE IN WAFER ROTATIONAL

During the wafer rotational grinding, the wafer is located on a porous ceramic vacuum chuck, so there are many factors that can affect the wafer shape in the process of the wafer grinding. The wafer shape has an important influence on the surface quality of the silicon wafer and it will be greatly different if the processing parameters are ...
