Choosing equipment for an animal feed production line is one of the most important decisions in a feed mill project. The equipment configuration directly affects production capacity, feed quality, pellet durability, energy consumption, labor cost, maintenance cost, and long-term profitability.
Many investors make one common mistake: they choose machines only by price or rated capacity. In reality, a good feed production line must be designed according to raw material characteristics, animal species, feed formula, pellet size, moisture requirements, production capacity, factory layout, automation level, local labor conditions, and future expansion plans.
A suitable animal feed production line should not only produce feed. It should produce stable, safe, uniform, and cost-effective feed at the required capacity.
1- Define the Feed Type First
Before choosing equipment, the first question is:
What type of animal feed will the line produce?
Different animals require different grinding fineness, mixing accuracy, conditioning temperature, pellet size, pellet durability, and cooling control.
Common animal feed categories
| Feed Type | Typical Pellet Diameter | Key Equipment Requirement |
|---|---|---|
| Poultry feed | 2.5–4.0 mm | Efficient grinding, mixing, pelleting, cooling |
| Pig feed | 3.0–5.0 mm | Fine grinding, good conditioning, stable pellet quality |
| Cattle feed | 4.0–8.0 mm | Strong mixer, larger pellet size, fiber handling |
| Sheep and goat feed | 3.0–6.0 mm | Fiber processing, uniform mixing |
| Rabbit feed | 3.0–4.0 mm | High pellet durability and low fines |
| Fish feed | 1.0–5.0 mm | Fine grinding, strong conditioning or extrusion |
| Shrimp feed | 0.8–2.0 mm | Ultra-fine grinding, high water stability |
| Pet food | 2.0–12.0 mm | Usually requires extrusion and drying |
| Premix feed | Powder form | High mixing accuracy, no pelleting required |
For example, a poultry feed line and an aquatic feed line may both be called “feed production lines,” but their equipment configuration is very different. Aquatic feed usually requires finer grinding, higher conditioning intensity, better drying or extrusion control, and higher water stability.
2- Determine the Required Production Capacity
Capacity is the foundation of equipment selection. The production line must match both current demand and future growth.
Common capacity levels
| Production Scale | Typical Capacity | Suitable User |
|---|---|---|
| Small farm feed line | 0.5–2 TPH | Farms, small cooperatives |
| Small commercial feed mill | 2–5 TPH | Local feed suppliers |
| Medium feed mill | 5–10 TPH | Regional feed manufacturers |
| Large industrial feed mill | 10–30 TPH | Commercial feed companies |
| Large-scale feed factory | 30–60 TPH or more | Group enterprises and large integrators |
TPH means tons per hour.
Capacity selection formula
Daily feed demand can be calculated as:
Required hourly capacity = daily feed demand ÷ available production hours
Example:
If a feed mill needs to produce 80 tons per day and operates 10 hours per day:
80 tons ÷ 10 hours = 8 TPH
In this case, the recommended equipment capacity should not be exactly 8 TPH. It is better to design a line of 8–10 TPH to leave room for cleaning, formula change, maintenance, and capacity fluctuation.
Recommended capacity reserve
| Project Type | Recommended Capacity Reserve |
|---|---|
| Farm-use feed line | 10%–15% |
| Commercial feed mill | 15%–25% |
| High-variety feed mill | 20%–30% |
| Large industrial project | 20%–35% |
If capacity is designed too close to the required output, the plant will frequently operate under overload, which increases downtime, energy consumption, and equipment wear.
3- Analyze Raw Material Characteristics
Raw materials determine equipment strength, process configuration, and energy consumption.
Key raw material factors
| Raw Material Factor | Why It Matters | Equipment Impact |
|---|---|---|
| Moisture | Affects storage, grinding, pelleting, cooling | May require drying or moisture control |
| Hardness | Affects grinding energy | Determines hammer mill power |
| Fiber content | Affects flowability and pellet quality | Requires stronger grinding and conditioning |
| Oil/fat content | Affects pellet durability | May need post-pellet oil spraying |
| Bulk density | Affects bin and conveyor design | Determines silo volume and conveyor capacity |
| Particle size | Affects grinding requirement | Determines pre-cleaning and crusher type |
| Impurities | Affects equipment safety | Requires cleaning, magnetic separation, screening |
| Formula variability | Affects process flexibility | Requires flexible batching and control system |
Example raw material influence
| Raw Material Type | Equipment Selection Consideration |
|---|---|
| Corn, wheat, sorghum | Standard hammer mill or roller mill |
| Soybean meal | Normal grinding and batching |
| Bran, DDGS, fiber materials | Flowability and dust control required |
| Grass, alfalfa, straw | Pre-crushing and strong fiber handling |
| Oil-rich materials | Pellet durability control required |
| Fish meal and animal protein | Odor, hygiene, and cross-contamination control |
| Premix and micro-ingredients | High-accuracy dosing and mixing required |
If the raw material contains many impurities, the line must include cleaning equipment such as screens, magnetic separators, and dust collection systems. Skipping these machines may reduce initial investment but can cause serious long-term problems, including hammer mill damage, die blockage, bearing failure, and feed contamination.
4- Choose the Correct Process Flow
A standard animal feed production line usually includes the following sections:
1- Raw material receiving and cleaning

Practical recommendation
For commercial feed mills, cleaning equipment should not be omitted. A small investment in cleaning and magnetic separation can protect expensive equipment such as hammer mills, pellet mills, dies, rollers, and bearings.
5.2- Grinding Equipment
Grinding is one of the most important steps in feed production. It affects digestibility, mixing uniformity, pellet quality, energy consumption, and capacity.
Hammer mill vs roller mill
| Equipment | Advantages | Suitable Application |
|---|---|---|
| Hammer mill | Flexible, widely used, suitable for many raw materials | Poultry, pig, cattle, general feed |
| Roller mill | More uniform particle size, lower fines in some cases | Corn-based feed, coarse grinding |
| Ultra-fine pulverizer | Very fine particle size | Aquafeed, shrimp feed, pet food |
Recommended particle size
| Feed Type | Suggested Particle Size |
|---|---|
| Broiler feed | 600–900 µm |
| Layer feed | 700–1,000 µm |
| Piglet feed | 400–600 µm |
