25 T/H Animal Feed Mill Plant in Peru

RICHI MACHINERY

Capacity Was Divided Before Equipment Was Selected

The inquiry reached RICHI in March 2025 with a broad capacity target but no finished factory layout. The decisive information was the product plan: most of the annual tonnage would be pig feed, poultry feed would use the same livestock route, and cattle and sheep feed needed a separate line with different grinding, conditioning and pellet-size requirements.

The customer wanted a plant in the 20–30 T/H class that could be operated by a regional team without turning every formula change into a complicated shutdown.

By June 2025, the two-line process, storage plan and multi-level building arrangement had been fixed. The contract was signed that month, equipment manufacturing started in July, and shipment from Qingdao to Callao was scheduled in October. Site installation and commissioning followed after the main machinery reached Peru.

A Regional Investor With Its Own Grain and Farm Demand

The customer is a regional agricultural investment group in northern Peru with interests in grain trading and poultry farming. That combination gave the project two demand channels from the beginning: feed for its own operations and commercial sales to nearby livestock producers. The plant was therefore sized as a real feed mill factory in Peru rather than as a single-farm line.

Four commercial reasons shaped the investment:

• Growing local demand for compound pig, poultry and ruminant feed
• Higher cost and longer lead time when finished feed has to travel from distant suppliers
• Access to corn, soybean meal and other feed ingredients through established trading channels
• Direct control over formula quality for the group’s own poultry operations while retaining capacity for external customers

The commercial objective was reliability before complexity. Automation is concentrated in batching, weighing, material routing and packing, while the equipment arrangement remains understandable for operators who need to switch between pig, poultry and ruminant production during a normal two-shift schedule.

A 4,760 m² Site Forced the Plant Upward

The animal feed processing plant occupies about 4,760 m² of land. That is compact for a 25 T/H factory with two production lines, raw-material storage, finished-feed storage, utilities, office and laboratory functions. Instead of spreading the process horizontally, the main production building uses five above-ground levels plus one underground level so gravity can replace part of the mechanical conveying between bins, batching, mixing and pelleting.

Functional Areas

• Raw-material receiving and warehouse zone connected to grain and meal storage
• Main production building with five operating floors plus one underground level
• Finished-product warehouse positioned close to the three packing machines
• Auxiliary rooms for compressed air, electrical distribution and maintenance
• Boiler house serving the steam-conditioning system
• Office and laboratory space for administration, formulation support and feed-quality checks

Terrain became part of the process design:
The site has a natural elevation difference. Instead of removing that difference through extensive earthwork, the layout uses stepped platforms and the multi-level production building to support gravity flow. This reduced unnecessary lifting between batching, mixing and pellet sections while preserving truck access around the site.

Three Feed Families Share Two Production Lines

The product schedule is the real capacity map for this animal feed production line in Peru. Pig and poultry feed share the higher-throughput livestock line because their combined annual demand is 100,000 tons. Cattle and sheep feed use the ruminant line, which is smaller but has more bin flexibility for fibrous ingredients and different pellet settings.

Product Type	Category	Annual Output (tons)	Production Line
Pig Feed	Livestock Feed	80,000	Line 1
Poultry Feed (Chicken, Duck)	Livestock Feed	20,000	Line 1
Cattle & Sheep Feed	Ruminant Feed	20,000	Line 2
Total	—	120,000	2 Lines

The two animal feed production lines share receiving, utilities and parts of the storage system but use different production priorities. The livestock line is configured around 20–24 T/H of pellet capacity from two parallel high-capacity SZLH pellet mills, while the ruminant line uses one SZLH350 rated around 5–6 T/H. Typical finished sizes are about 2–4 mm for poultry feed, 3–4 mm for pig feed and 4–6 mm for cattle and sheep pellets, with crumble production used where starter-feed specifications require it.

The Ingredient Table Nearly Closes the Entire Annual Output

The factory uses a corn-and-soybean-meal base, but the formula portfolio also includes cottonseed meal, rapeseed meal, wheat bran, fish meal, broken rice, flour, soybean oil and additives. The listed annual procurement basis totals about 120,124 tons, which is close to the 120,000 T/Y finished-feed plan and gives the project a coherent mass-balance basis before steam addition, moisture changes and normal inventory movement are considered.

Raw Material	Annual Consumption (tons)	Max Storage (tons)	Storage Method
Corn	53,000	4,500	Silos
Soybean Meal	45,000	1,000	Silos
Cottonseed Meal	5,900	200	Warehouse
Rapeseed Meal	1,500	200	Warehouse
Wheat Bran	9,500	500	Warehouse
Fish Meal	1,785	500	Warehouse
Broken Rice	350	100	Warehouse
Flour	39	10	Warehouse
Soybean Oil	50	10	Storage Tank
Additives	3,000	500	Warehouse

Moisture control starts with corn:
Corn is the largest single ingredient and the main source of seasonal moisture variation. Incoming lots are therefore checked before silo transfer. During commissioning, pellet stability improved after conditioning time and steam input were adjusted to match the actual corn condition instead of trying to solve moisture variation by grinding the material finer.

Machine Quantity Follows the Product Split

The animal feed plant machinery is divided by duty rather than duplicated evenly. The ruminant route needs one grinding and pelleting train for 20,000 T/Y, while the pig-and-poultry route carries five times that annual volume and therefore uses two hammer mills and two high-capacity pellet mills.

One Front End Two Different Feed Routes

The complete feed mill plant in Peru shares raw-material receiving, utilities and part of the storage network, then separates materials according to whether they are entering the livestock line or the ruminant line. That arrangement avoids building two isolated factories on the same 4,760 m² site.

① Raw Material Receiving and Storage

Materials enter the factory in three handling groups:

• Granular materials: mainly corn and other grains that require cleaning and grinding
• Powder materials: soybean meal, bran and protein meals that can bypass hammer milling when particle size is already suitable
• Micro-additives: vitamins, minerals and specialty ingredients handled through controlled small-ingredient dosing

Bulk corn and soybean meal are assigned to silos where turnover justifies it, while lower-volume meals, bran, fish meal and additives remain in warehouse storage. Soybean oil is held in a dedicated tank.

The separation keeps storage capacity aligned with annual consumption and reduces unnecessary handling before batching.

② Cleaning and Metal Protection

Before grain or meal enters grinding and batching:

• Drum screens remove coarse foreign material and protect downstream conveying equipment
• Magnetic separators remove ferrous contamination before hammer mills, scales and pellet presses

This protection is especially important on a 25 T/H line because one metal object can stop a high-load grinding or pelleting machine and interrupt an entire production shift.

Meals that already meet the required particle size can bypass grinding and move directly to the appropriate batching bins.

③ Route Selection Before Grinding

• Ruminant line: one controlled feeding route sized for the smaller 5–6 T/H production branch
• Livestock line: two feed-entry routes support the higher-volume pig and poultry schedule

Bucket elevators direct ingredients either to grinding bins or to batching bins according to the active formula and whether size reduction is required.

④ Grinding by Animal and Pellet Requirement

Grinding is where the two lines begin to behave differently. Pig and poultry formulas need a more uniform fine fraction for small pellets and crumble, while ruminant feed can tolerate a coarser structure and may include more fibrous ingredients.

The installed arrangement is:

• One hammer mill on the ruminant route for the 20,000 T/Y cattle and sheep program
• Two hammer mills on the pig and poultry route so grinding capacity matches the 100,000 T/Y line duty

Each hammer mill receives grain through controlled feeding equipment so motor load stays stable during moisture and density changes.

• Pneumatic gates regulate flow from the grinding bins
• Impeller feeders smooth the feed rate and reduce sudden load changes at the hammer mill

Screen selection sets the target particle-size range, and a screen-failure detection point is reserved because broken screens can send oversize particles into batching and later affect pellet quality.

Ground material is lifted to batching bins dedicated to the active production line.

⑤ Automated Batching and Mixing

The ruminant feed production line in Peru uses:

• One automated batching system
• 21 batching bins, including reserved positions for grass powder and other fibrous materials
• Two weighing scales to separate larger ingredients from lower-dose additions

The pig feed production line in Peru and poultry feed mill in Peru share the larger livestock route:

• One high-throughput batching system serving pig and poultry formulas
• 28 batching bins for the larger ingredient portfolio and faster formula turnover
• Large, medium and small weighing ranges so corn and soybean meal are not weighed on the same tolerance basis as minor ingredients

The control system manages formula selection, weighing sequence and discharge timing:

• Approved formulas are stored in the control system and released by production order
• Major and minor ingredients are weighed automatically before mixer charging
• Soybean oil addition is metered digitally so liquid percentage stays tied to the selected formula

After mixing, feed is directed either to pelleting bins or to finished-product routing when a formula is produced in mash form.

⑥ Steam Conditioning Pelleting and Cooling

This section defines the finished pellet capacity of the animal feed pellet plant. The livestock line and ruminant line share the same steam utility but use different pellet-mill sizes and pellet specifications.

• Mixed meal is conditioned with saturated steam before entering each pellet mill
• Two 2 T/H natural-gas boilers provide up to 4 T/H of installed steam capacity for the pelleting section

Three pellet mills are installed:

• Two high-capacity feed mill pellet machines serve the 100,000 T/Y pig-and-poultry line
• One smaller pellet mill serves the 20,000 T/Y cattle-and-sheep route; die and operating settings change with the required 4–6 mm ruminant pellet

Immediately after pelleting:

• Each active pellet route discharges to its matched counterflow cooler
• Pellet temperature is reduced toward ambient before screening and storage
• Cooling removes retained heat and stabilizes moisture before bagging

Product finishing changes by animal group:

• Poultry starter pellets can be crumbled, while pig and ruminant products are screened to remove fines and maintain the specified pellet size

⑦ Three Packing Machines Support the Product Mix

• Three automatic bagging machines are shared across the finished-feed program
• Nominal packing rates:
  • Up to about 600 bags/hour for pellet products
  • Up to about 500 bags/hour for powder or mash products

US$1.8 Million Fixed Investment for the Completed Feed Mill

• Total Fixed Investment: approximately US$1.8 million
• Feed Production Equipment Package: approximately US$1.2 million

The remaining fixed-investment scope covers the multi-level building interfaces, foundations, electrical distribution, two natural-gas boiler systems, dust-control connections, freight, inland delivery, installation, commissioning and the site work needed to integrate three pellet mills and two production lines on a compact property.

• Shared receiving, utility and selected conveying systems reduce duplicated equipment between the two lines
• Automation is concentrated on weighing, batching, routing and packing where repeatability has the highest production value
• The vertical layout uses gravity between process levels and limits unnecessary horizontal conveying

Commissioning Started With Steam and Batch Discipline

The first stable production target was not 25 T/H. It was repeatable feed quality across both lines. Startup checks therefore focused on moisture response, batching sequence, steam input and operator control of the automated system.

• Initial pellet batches showed moisture variation as corn condition changed between deliveries
• Steam addition and conditioning residence time were tuned by formula until pellet moisture and durability stabilized
• Operators required more training on batching logic, bin assignment and recipe control than on basic machine start/stop operation
• Dust collectors performed as designed, but housekeeping and filter inspection remained part of the daily operating routine

Peru Gives the Livestock Line a Strong Poultry Base

The project’s largest line is pig and poultry feed, and that fits the Peruvian feed market. Poultry is the main driver of corn demand in the country, while pig, dairy and regional cattle production create additional outlets for commercial compound feed. The plant can therefore use the same core ingredient network across several animal categories instead of depending on one customer segment.

• Poultry production creates the largest recurring demand for the high-capacity livestock feed plant in Peru
• Pig production supports the 80,000 T/Y pig-feed program and gives the line a second large-volume product family
• Cattle and sheep producers provide a separate market for the 20,000 T/Y ruminant line

Product flexibility is part of the investment case.
A complete feed mill plant in Peru with separate livestock and ruminant routes can serve the owner’s internal farms while also selling commercial feed, without forcing every animal formula through the same grinding and pelleting settings.

A 25 T/H Feed Mill Only Works When the Product Split Is Real

The value of this 25 T/H animal feed mill plant in Peru comes from capacity allocation rather than from one oversized machine. The 100,000 T/Y pig-and-poultry program gets two high-capacity pellet mills; the 20,000 T/Y ruminant program gets one smaller pellet mill and more formulation flexibility. Shared storage, steam, utilities and packing keep the overall investment under control.

• Raw-material storage is sized around annual consumption and turnover instead of one uniform stock ratio
• Pellet-mill quantity follows line duty, maintenance needs and product size rather than being divided evenly between the two lines
• The multi-level process uses the compact 4,760 m² site and its natural elevation instead of forcing a wide horizontal factory layout

The same headline capacity would not justify the same equipment in another country or customer scenario. Product mix, annual operating hours, pellet size, formula structure, bagging ratio and available site height can change the correct solution substantially.

If a similar feed mill factory is being planned, start with annual tonnage by animal category, working days, shift hours, ingredient storage days and the percentage of each product that will be pelleted or sold as mash. Those inputs determine whether the project should use one line, parallel pellet mills or separate livestock and ruminant production routes.
