The hay pellet mill is specially designed for pelleting hay into pellets for feed or for heating fuel. Traditionally, hay or hay pellets are used as feed for cattle, rabbits, sheep, etc. But recently, the need to use hay pellets for heating is emerging. Raw hay fodder mainly consists of grasses and other herbs that are dried, compressed and stored as animal feed. Traditional hay is usually bundled and compressed into bales for easy storage and stacking. Although compressed to a certain extent, the degree of compression is small and requires a large amount of storage space.
