Thru-feed grinding is a type of centerless grinding. During this process, the workpiece passes through the machine itself. During this process, the workpiece passes through the machine itself. It proves to be an effective option for single-size diameter parts anywhere from a small dowel pin to a 16" shaft.
Work is fed in a continuous streamthrough the grinder by the feed mechanism locating at the front of the machine. A variety of feeding methods, including chain feed, belt feed, pusher feed, and others are available. A pair of guide bars retain the work pieces as they pass through the grinding zone, exiting at the rear of the machine. II.

Grinding or particle-size reduction is a major function of feed manufacturing. Many feed mills pass all incoming ingredients through a grinder for several reasons: (a) clumps and large fragments are reduced in size, (b) some moisture is removed due to aeration, and (c) additives such as antioxidants may be blended.
