10–12 T/H Ring Die Feed Pellet Machine in Mexico

Why the Plant Moved from Two SZLH320 Units to One SZLH420 Main Line

The two older feed pellet mills provided a combined nominal capacity of approximately 6–8 T/H. Producing 25,000 tonnes through that capacity requires roughly 3,125–4,167 effective pelleting hours per year. Across 300 production days, that represents about 10.4–13.9 effective hours per day before allowing for maintenance, die changes or unexpected interruptions.

The SZLH420 changes the operating schedule significantly. At 10–12 T/H, approximately 25,000 tonnes require about 2,083–2,500 effective pelleting hours per year, equivalent to roughly 6.9–8.3 hours per day over 300 days. The larger machine therefore provides the main broiler line with useful operating reserve without relying on claims of unrealistic energy savings or continuous maximum output.

The older pellet mills remain available for smaller contract runs, allowing the new machine to stay on its higher-volume broiler program for longer production campaigns.

SZLH420 Project Configuration

The 10–12 T/H rating represents suitable feed formulas under correctly prepared grinding, steam-conditioning and ring-die conditions. Actual production varies with formula composition, pellet diameter, mash moisture, oil level, fiber content and die resistance. A high-fat formula or smaller pellet diameter may operate differently from a standard broiler finisher feed even when both products use the same SZLH420.

Jalisco Is a Practical Location for Commercial Broiler Feed

Jalisco has one of Mexico's strongest livestock economies and a substantial poultry production base around its wider agricultural and feed-manufacturing sector. This gives a Guadalajara-area contract feed mill access to a concentrated regional customer base as well as established grain, ingredient and transport networks.

Maize is particularly relevant to the project because it remains an important feed-energy ingredient in Mexico and Jalisco is a major maize-producing state. Soybean meal, other protein meals, oils, minerals, amino acids and premixes are incorporated according to nutrition specifications and market availability.

The project does not use a fixed formula such as 60% maize or 25% soybean meal. Commercial broiler formulations change with ingredient analysis, prices, bird stage and customer nutrient specifications, so the pellet machine must tolerate controlled formula variation rather than depend on one permanent recipe.

From 1–3 mm Mash to 4mm Broiler Pellets

Maize and other ingredients requiring grinding first pass through the existing animal feed hammer mill section. For the broiler products handled by the SZLH420, the major ground ingredients are generally prepared to an approximately 1–3 mm particle range before batching and mixing.

The mixed mash moves through a buffer bin and controlled feeder into the conditioner. Steam prepares the formula for compression by adding heat and moisture and changing the physical behavior of the mash before it enters the ring die.

The plant's main grower and finisher product uses approximately 4 mm pellets. Where starter feed requires a smaller finished form, the line can manufacture a suitable parent pellet and use the existing crumbler downstream. This avoids treating one exact pellet diameter as appropriate for every stage of broiler production.

The Conditioner Supports Pelleting but Does Not Set One Universal Temperature

The 7.5 kW conditioner is an important part of the SZLH420 configuration, but its operation is determined by the actual formula. Steam quality, initial mash moisture, cereal starch characteristics, oil addition and required feed specification all influence conditioning.

The plant therefore does not use a permanent statement such as 75–80°C being optimal for every broiler formula. Operators monitor mash condition, pellet-mill load, finished pellet quality and downstream cooling performance when establishing production settings.

Likewise, the conditioner should not be credited independently with guaranteed digestibility improvements or pathogen elimination. Those outcomes require defined process validation and feed-safety controls beyond the presence of a conditioner motor.

Why the Ring Die Is Selected from Formula Rather Than Diameter Alone

The project uses a ring die selected around the actual broiler formula and approximately 4 mm product requirement. Hole diameter is only one design parameter. Effective compression length, material characteristics and die configuration determine how much resistance the feed experiences during pellet formation.

For that reason, the project does not use a universal 1:10 compression ratio or promise a fixed ring-die life of 2,500 or 3,000 tonnes. Formula abrasiveness, mineral content, roller adjustment, die quality, production rate and maintenance practices all influence wear.

The customer keeps suitable wear parts and die-handling equipment available, but scheduled changeover time is based on the real workshop arrangement rather than a guaranteed 30-minute figure.

Replacing the Pellet Mill Does Not Automatically Upgrade the Whole Plant

A 10–12 T/H poultry feed pellet machine can only deliver its expected production if the upstream and downstream sections support the same flow. The Jalisco project therefore includes an interface review of grinding, batching, mixing, mash storage, steam supply, cooling, screening and finished-feed handling.

The cooler is especially important because the previous line was originally designed around smaller pellet mills. If it cannot continuously receive approximately 10–12 T/H of hot pellets, the new SZLH420 would simply move the bottleneck one stage downstream.

The same applies to the mixer and mash bins. RICHI therefore evaluates the complete mass flow before the plant schedules the new pellet mill at full output.

Capacity Reserve Is More Important Than Claimed Energy Savings

The main economic value of this upgrade is operating flexibility. The former 6–8 T/H combined pelletizing capacity required long schedules to produce approximately 25,000 T/Y. The new 10–12 T/H main machine can process the same annual tonnage in fewer effective hours and leave more time for maintenance and future production growth.

This does not mean the 110 kW machine automatically consumes a fixed 9 or 10 kWh per tonne or reduces energy use by a particular percentage. Nameplate motor power cannot be divided by rated output and treated as actual plant energy consumption. Real specific energy depends on machine load, formula, conditioning, pellet diameter and auxiliary equipment.

Meaningful energy comparison requires measured electrical data from both the old and new systems under comparable production conditions.

Shipping the SZLH420 through Manzanillo

The Ring Die Feed Pellet Machine in Mexico is prepared for export from Qingdao, China, with the Port of Manzanillo used as the Pacific container gateway before inland transport toward Jalisco and the Guadalajara area.

Before shipment, RICHI reviews the customer's 60 Hz electrical requirements, new foundation load, feeder and conditioner elevation, steam interface, maintenance clearance, pellet discharge position and connections to the existing cooler and downstream equipment. These checks are necessary because a 110 kW SZLH420 cannot be assumed to occupy the same foundation and service connections as an older 37 kW SZLH320 without modification.

What to Confirm Before Upgrading to a Larger Ring Die Pellet Mill

• current and target annual pelleted-feed tonnage;
• effective operating hours of the existing machines;
• main feed formula and ground mash particle size;
• required pellet or crumble specifications;
• mixer, mash-bin and feeder capacities;
• steam supply and conditioner requirements;
• cooler, screen and packaging throughput;
• electrical capacity, foundation and installation space.

A 10–12 T/H Ring Die Feed Pellet Machine in Mexico

This Ring Die Feed Pellet Machine in Mexico project uses one RICHI SZLH420 with a 110 kW main motor to establish a higher-capacity broiler feed pelleting section at a commercial mill in Jalisco. Feed ingredients are prepared to an approximately 1–3 mm mash before conditioning, while the principal finished product is approximately 4 mm broiler pellets. The machine provides a reference capacity of around 10–12 T/H.

At approximately 25,000 T/Y, the main pellet line requires about 2,083–2,500 effective operating hours per year, or roughly 6.9–8.3 hours per day across 300 production days. For another Mexican feed manufacturer evaluating an SZLH420, RICHI Machinery needs the annual tonnage, formulas, mash size, pellet specifications, steam conditions and capacities of the surrounding equipment before confirming the final ring die and plant-integration configuration.
