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.

A grinder is commonly used to precisely shape and finish the given materials with low surface roughness and high surface quality. Grinding machine is a type of machine used to grind the workpieces. It basically uses emery or an abrasive wheel as the cutting tool. The grinding process is truly a chip producing machining process.

Mid-quality grade—good choice for applications where the almonds with minimal sorting/processing can be incorporated with other ingredients; for example, inside a confectionery product a higher level of chipped and scratched kernels is accepted. Also appropriate for further processing, such as blanching, grinding, roasting, dicing and slicing.
