A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Regrind resins are reclaimed from previously molded parts. These resins have undergone at least one heat history due to molding or extrusion. These parts are chopped and ground, once they reach the end of their service lives or if they are rejected from use. Mid Continent Plastics is a leading plastic regrind broker in the US.

A rod mill and a stirred mill with the same stainless steel media were used to regrind rougher flotation concentrates. Different chalcocite flotation recovery was achieved in the cleaner stage after regrinding in tumbling and stirred mills. The factors contributing to the different recovery included particle size, the amount of created fresh ...

matter how badly the tool may be damaged, we can regrind nearly any end mill, regardless of condition. By the off chance we cannot recondition an end mill to customer required specification, we will recycle the tooling, unless otherwise noted. We will resharpen or recondition any tool, regardless of original manufacturer.

Tread rails shall be manufactured from high-impact Regrind PET-G complete with co-extruded soft-durometer cushions. Overall depth without frame is 7/16" (11.1 mm). Supplied in mill (standard) or one of 9 optional colors as offered by manufacturer. (Call factory for custom colors.) Choose from anodized of heavy-duty powder coat finish.

Should You Use Re-Grind? The simple answer: Maybe. I just returned from a design conference sponsored by the Society of Plastics Engineers, with support from the Rhode Island School of Design, the Industrial Designer's Society of America, the Design Management Institute, and others.
