Components of the pelleting system: An in-depth look at the various aspects of making feed pellets

摘要

This article will address the components in a pelleting system for animal feed. It will be a walk-through of a system. Specific information and features about different pieces of equipment used in the system will be addressed in a future article. A diagram of a typical pelleting system is shown in Figure 1. The system begins with the supply of the feed (mash) to be pelleted. The mash is usually a mixture of relatively dry ingredients that has been formulated and blended prior to delivery to the supply bins. This mash is a mixture of particles of different sizes uniformly blended together. It is important that in moving these ingredients into the supply bins that particle separation is minimized. In filling a bin with materials of different types and sizes of particles, some separation will occur. The spout into each bin should be designed so the material flow is vertical as it enters the bin, and the inlet spout is located in the center of the bin top.
