Pellet diameter is set by the die hole and varies by growth stage: starter chicks (0–6 weeks) need fine 1.0–2.5 mm feed, while grower and finisher birds of both types use 2.5–4.5 mm pellets. Because standard poultry dies usually start at 3 mm, starter feed is best made by producing 3 mm pellets and passing them through a crumbler to reach 1–2.5 mm crumbles—making a crumbler a must-have for any operation raising chicks or layer pullets. Broiler pellets can be harder for durability, whereas layer pellets should stay moderate so birds keep eating well, and broiler farms generally need higher hourly capacity than steady layer operations.
Choosing the right machine comes down to scale and feed form: a flat die pellet machine with adjustable aperture (Φ3–8 mm) suits small farms and home use, while a ring die machine with a matching crumbler fits commercial plants and export production. Zhengzhou Weiwei Machinery, a 40-year manufacturer under the WEIWEI brand, offers the 9KLP flat-die and GPL ring-die series—both with adjustable dies, optional crumblers, OEM customization, and CE/ISO certification—so one platform serves your whole flock, whether you make hard broiler pellets or layer crumbles.
