Pelleting Line — definition
Processing sequence within a feed mill that compresses conditioned mash into dense pellets using a pellet press, followed by cooling, screening and, where required, coating.
A pelleting line typically includes a conditioner that adds steam and moisture to the mash before it passes through a pellet die, followed by a cooler to remove heat and moisture and a screener to remove fines. Pellet quality, measured by durability and fines percentage, affects feed handling losses and animal intake efficiency.
Why it matters to industrial buyers
Pellet quality directly affects on-farm feed wastage and handling losses, making pelleting line specification a meaningful factor in the overall economics of a feed mill investment.
Key reference points
Key quality metric
Pellet durability index and fines percentage are commonly used to assess pellet quality.
Typical sequence
Conditioning, pelleting through a die, cooling and screening, with optional post-pelleting coating.
How it is used in practice
The pelleting line specification included a target pellet durability index to minimise fines generation during transport to the aquaculture farms.
Frequently asked questions
Does pellet die wear affect capacity?
Yes, die wear reduces throughput and pellet quality over time, making it a component tracked under spare parts strategy and maintenance planning.
Are pelleting lines the same for all feed types?
No, die specification and conditioning parameters are adjusted for species-specific formulations, such as aquafeed requiring different durability than poultry feed.
