3–4 T/H Feed Mill Pellet Machine in Kenya

Why the Cooperative Upgraded from SZLH250 to SZLH320

The previous SZLH250 feed pellet machine provides approximately 1–1.5 T/H. At an annual production volume of around 5,000 tonnes, that smaller machine would require approximately 3,333–5,000 effective pelleting hours every year, creating long operating schedules and limited reserve capacity for maintenance or seasonal peaks.

The 3–4 T/H SZLH320 changes the operating balance. Producing 8,000 tonnes requires approximately 2,000 hours at 4 T/H or about 2,667 hours at 3 T/H. Across 300 production days, this equals roughly 6.7–8.9 effective pelleting hours per day. The cooperative can therefore expand annual production without forcing the pellet mill to operate close to continuous duty.

The old SZLH250 can also be retained as standby equipment or assigned to smaller specialty batches if its condition and plant layout allow, giving the cooperative additional production flexibility.

SZLH320 Project Configuration and Capacity

The 3–4 T/H range refers to suitable poultry-feed formulas under correctly prepared grinding, conditioning and die conditions. Actual output varies with formula composition, pellet diameter, mash moisture, oil level, steam quality and ring die resistance. The machine should therefore be sized from the required annual production schedule rather than assuming that every formula will continuously operate at exactly 4 T/H.

Feed Ingredients Match Kenya's Milling and Oilseed Supply

The cooperative uses ingredients available through Kenya's feed and grain markets rather than one fixed recipe. Maize and maize-milling by-products provide important energy sources, while wheat bran and wheat pollard are widely used feed ingredients. Oilseed materials such as sunflower cake and cottonseed cake can contribute protein and energy, while soybean meal, minerals, amino acids and premixes are incorporated according to formulation requirements and availability.

Kenyan agricultural data confirms that maize remains a major crop, while feed-industry surveys in the Rift Valley identify maize, maize germ, wheat bran, wheat pollard, sunflower cake and other oilseed cakes among ingredients handled by regional feed processors.

The project does not lock the cooperative into percentages such as 50–60% maize or 10–15% sunflower cake. Ingredient prices, nutrient analysis and availability fluctuate, so the nutritionist adjusts the formulation while maintaining the required energy, protein, amino acid, mineral and vitamin specifications.

From 1–3mm Mash to Broiler Pellets

Before pelletizing, cereal ingredients are cleaned and ground to an approximately 1–3 mm range where required. Already fine materials such as some meals or premixes do not need unnecessary regrinding. Ingredients are then weighed through the batching system and mixed into a homogeneous mash before entering the SZLH320 feeder and conditioner.

The conditioner introduces steam to prepare the mash for compression through the ring die. Steam can improve mash plasticity and support pellet formation, but the operating temperature is not fixed permanently at 75–80°C. Formula composition, initial moisture, steam quality, retention time and the feed mill's product requirements determine the actual conditioning settings.

For starter feed, the plant can produce an approximately 3 mm parent pellet and then pass it through the existing crumbler to obtain the required smaller feed form. Later broiler products use approximately 4 mm pellets. This is more technically accurate than describing broiler starter feed simply as intact 3 mm pellets in every production program.

Why Pellet Quality Cannot Be Guaranteed by the Pellet Mill Alone

The SZLH320 is the central forming machine, but pellet quality depends on the complete preparation process. Poor grinding uniformity, inaccurate batching, inadequate mixing, unstable steam supply or incorrect cooling can all increase fines even when the pellet mill itself is operating correctly.

Ring die compression ratio also cannot be selected from pellet diameter alone. RICHI evaluates the actual formula, fiber level, oil content and desired pellet characteristics before specifying the die. Likewise, claims such as a fixed 1,500–2,500-tonne die life are avoided because wear depends on formulation, mineral contamination, operating adjustment and die metallurgy.

The same principle applies to energy consumption. A 37 kW motor rating does not mean every tonne of feed consumes one universal number of kilowatt-hours. Practical specific energy depends on throughput and actual machine load.

Existing Equipment Must Support the New 3–4 T/H Rate

Replacing an SZLH250 with an SZLH320 only solves the original bottleneck if the surrounding equipment can support the higher production rate. The cooperative therefore checks hammer-mill capacity, mixer batch cycle, mash-bin volume, steam supply, cooler throughput, crumbler and screen capacity, and finished-feed packaging before increasing scheduled output.

The cooler in particular must be able to receive the full 3–4 T/H pellet flow. If an old cooler was originally sized only around the SZLH250, increasing pellet-mill capacity without checking cooling would simply create another restriction immediately downstream.

This interface review is one of the main advantages of upgrading one machine inside an existing mill: equipment that remains correctly sized can be retained, while only the true bottlenecks need modification.

Why the 8,000 T/Y Target Is Realistic

Kenya continues to face significant demand for affordable livestock feed and feed ingredients. Government and FAO material has identified feed availability and cost as constraints to livestock production, while national feed assessments have documented substantial supply gaps.

For this cooperative, however, expansion is based on its own member demand rather than a national market forecast. At 3–4 T/H, producing 8,000 tonnes requires roughly one normal production shift on most operating days. This gives the plant room for maintenance, product changeovers and seasonal production peaks without requiring unrealistic 20-hour continuous schedules.

Shipping the SZLH320 through Mombasa

The Feed Mill Pellet Machine in Kenya is prepared for export from Qingdao, China, with the Port of Mombasa used as the national gateway before inland transport toward the Rift Valley. Kenya Ports Authority describes Mombasa as a major East and Central African gateway with conventional and container terminals and extensive inland connectivity.

Before shipment, RICHI Machinery checks the existing foundation, electrical supply, mash-bin position, steam connection, pellet discharge elevation, cooler capacity and maintenance access. This allows the SZLH320 to be integrated into the operating plant with targeted modifications instead of assuming it can simply occupy the exact SZLH250 installation position without dimensional or load checks.

What to Confirm Before Upgrading a Feed Pellet Machine

• existing and target annual feed production;
• required effective pelleting hours per day;
• main feed formula and ground mash particle size;
• required pellet and crumble specifications;
• hammer mill, mixer and mash-bin capacities;
• available steam quality and conditioner interface;
• cooler, screener and packaging capacity;
• electrical supply and workshop installation space.

A 3–4 T/H Feed Mill Pellet Machine in Kenya

This Feed Mill Pellet Machine in Kenya project uses one RICHI SZLH320 poultry feed pellet machine with a 37 kW main motor to expand a Rift Valley cooperative feed plant from approximately 5,000 T/Y toward 8,000 T/Y. Prepared poultry-feed mash is generally controlled around 1–3 mm before conditioning and pelletizing, while the main broiler products use approximately 3 mm parent pellets for crumbling and approximately 4 mm finished pellets for later growth stages.

At 3–4 T/H, the 8,000 T/Y target requires approximately 2,000–2,667 effective pelletizing hours per year, or roughly 6.7–8.9 hours per production day over 300 days. For another cooperative considering an upgrade, RICHI needs the current machine capacity, annual output, target tonnage, formulas, pellet sizes, operating schedule and capacities of the existing upstream and downstream equipment before confirming whether SZLH320 is the correct expansion model.
