Food Waste Depackaging Systems - BioCycle BioCycle

Principles Of Materials Separation. Organics recycling is, in part, a search for order, a processing of heterogeneous materials into purer components. This quest invariably requires some materials be separated from other materials. In its simplest form, separation is a binary process, splitting a feed material into two components.

Mill (grinding) - Wikipedia

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 (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
