As people expect, there are various types and designs of small feed pelletizers for people to choose from in the process of feed processing. The design of each feed pellet machine has its own advantages and disadvantages. The main types of common small feed pelletizers are flat die pelletizers and ring die pelletizers. The flat die pellet machine first appeared in the early 20th century and was mainly used for the production of animal feed. The ring die pellet machine appeared later, and it was not really developed until the 1950s.
The original purpose of all pellet machines is to compress animal feed into pellet form. Processing animal feed into pellets has the following advantages. First of all, it can produce specific mixed feed, minerals and vitamins for each animal. It can also be produced in the form of pellets and it is easy to quantify the correct feeding amount every day. In the end, the cost of transporting the feed to the farm is greatly reduced due to the increased density and density of compressed pellets. It was not until the 1970s that some animal feed manufacturers began to try to produce wood pellets for fuel.
