When crumbling, careful attention must be given to the roll setting at both ends to keep the rolls parallel. The normal procedure is to set the roller gap and then catch the crumbles from each end of the rolls.
Conditioning provides time for steam and other liquids to be absorbed ensuring uniform distribution of heat. It also improves compressibility and binding properties of feed mixtures by using: heat, moisture and time.
The factors that influence pellet quality are: formulation, grinding, conditioning, type of machinery and cooling, but it’s generally agreed that the formulation is by far the most important element affecting the process.
Several studies clearly indicate that pelleted feed improves animal performance and most feed mills are using the pelleting process to reduce pathogens, increase the density of the feed and minimize segregation of ingredients during transport and feeding.
