Chicken Feed Mill Expansion in Nigeria

RICHI MACHINERY

Expanding Capacity Without Rebuilding a Working Factory

The client already had the commercial foundation needed for a larger feed operation: established ingredient purchasing, an operating production site and access to poultry farms and feed distributors. The investment decision was therefore driven by throughput, reliability and production flexibility. Existing assets that could still perform useful work remained part of the factory, while new equipment was concentrated where additional capacity and better process control created the greatest operational value.

For an expansion of this type, simply installing another pellet mill would not solve the problem. The upstream grinding and batching sections must supply material at the required rate, the mixer must maintain batch accuracy, conditioning must provide stable feed to the pellet mills, and cooling and screening must accept the output without becoming downstream restrictions. The new poultry feed production line was therefore integrated as a complete processing route.

1. Increase hourly production while continuing to use serviceable existing infrastructure.
2. Create greater production flexibility for starter, grower and finisher feed.
3. Reduce the impact of maintenance on total factory output.
4. Provide an expansion route that can support longer operating hours as sales increase.

That approach also controls capital use. Instead of paying to duplicate every building, warehouse and utility already available on site, investment is directed toward equipment and interfaces that increase saleable feed output. For the customer, the chicken feed mill expansion in Nigeria therefore combines capacity growth with better use of the factory it already owns.

Raw Materials and Finished Feed Strategy

The chicken feed mill plant is designed for conventional poultry-feed ingredients available through commercial supply channels in Nigeria. Maize is the principal cereal ingredient, while soybean meal provides an important protein source. Depending on formulation and purchasing conditions, suitable cereal by-products can be introduced alongside vegetable oil, premix, minerals and other controlled micro-ingredients.

For the initial annual production target of approximately 35000 tons, purchasing quantities are not locked into one fixed formula. Different broiler products use different ingredient ratios, and commercial formulations may be adjusted when maize, soybean meal or approved alternative ingredients change in price or quality. The receiving, storage and dosing system therefore provides enough segregation to support formula changes without treating every ingredient as interchangeable.

The poultry feed plant produces several physical feed formats from the same factory. Broiler starter can be supplied as crumble to give young birds a manageable and relatively uniform particle size, while grower and finisher products can be produced as larger pellets, commonly around 3–4 mm according to the customer’s product specification. Mash products can also bypass pelleting when the sales program requires them.

• Broiler starter feed: controlled fine crumble or other customer-specified starter format.
• Broiler grower feed: pellet or crumble format selected according to the feeding program.
• Broiler finisher feed: commonly larger pellets for the final feeding stage.
• Other poultry formulas: produced only after formula, raw-material and process requirements are confirmed.

This flexibility matters commercially because feed cost is heavily influenced by ingredient purchasing. The factory can manage seasonal procurement through planned storage and controlled formula changes instead of relying on one fixed raw-material combination throughout the year.

Process Design for the 20 T/H Chicken Feed Line

The process is organized around two material streams before batching: bulk grain that requires cleaning and grinding, and meals or minor ingredients that can enter dedicated receiving and storage routes. They converge at the batching system before mixing and pellet processing. This arrangement prevents unnecessary grinding of ingredients that already have suitable particle characteristics and gives the operator better control over individual raw materials.

1. Receiving and cleaning: maize is unloaded through the receiving system and passes through screening, aspiration and magnetic separation before storage or grinding. Separate intake arrangements are used for bagged meals and minor ingredients.
2. Grinding: cleaned maize enters the hammer mill feed grinder. Screen specification and operating parameters are selected according to the required poultry-feed particle size rather than using one grinding setting for every formula.
3. Batching and micro-dosing: ground grain, protein meals and other major ingredients are weighed from their respective bins. Premix, minerals and other low-inclusion ingredients are introduced through a controlled micro-ingredient route.
4. Mixing and liquid addition: weighed ingredients enter the feed mixer machine, where vegetable oil and other approved liquids can be accurately metered. Mixing performance is verified to maintain formula uniformity.
5. Conditioning and pelleting: mixed mash is conditioned with steam before entering the SZLH-series ring die pellet machine section. Multiple pelletizing units are used so the required 20 T/H system capacity does not depend on one undersized machine.
6. Cooling: hot pellets enter counterflow coolers immediately after pelleting. Airflow and residence time are adjusted to production rate, pellet size and ambient conditions.
7. Crumbling and screening: starter products can pass through a crumbler to create the required particle distribution. Screening separates acceptable product from fines, with clean recoverable fines managed through the designed return route.
8. Weighing and packing: finished feed is weighed, bagged, lot identified and transferred to the warehouse for dispatch to farms, distributors or other customers.

The chicken feed pellet machine section is configured together with the cooler, crumbler and screener rather than selected in isolation. This is particularly important when the factory changes between starter crumble and larger grower or finisher pellets, because throughput, die specification, cooling load and downstream handling conditions all change with the product.

Local aspiration is provided at high-dust transfer points such as receiving, grinding, batching and packing. Equipment interlocks prevent downstream machines from being overloaded when a preceding section stops, while magnets and cleaning devices protect critical machinery from foreign material. These controls support both uptime and feed-quality consistency in the chicken feed mill expansion in Nigeria.

Equipment Configuration Designed as a Balanced System

The expansion equipment is sized from the 20 T/H production requirement and the actual duty of each processing stage. The pelletizing section uses parallel units instead of relying on one small pellet mill, while grinding, mixing, cooling, screening and conveying are matched to the required hourly material flow. Final motor powers and equipment quantities are coordinated during detailed engineering so that one undersized section does not restrict the whole line.

Several conveyors, elevators and storage bins are distributed between these main machines. Their capacities are not selected independently: conveying rate, lift height, bin residence time, discharge characteristics and equipment start-up sequence are checked against the mass flow of the line. The same principle applies to the poultry feed pellet machine section and its downstream cooler and screening system.

For an expansion project, interface measurements are particularly important. Existing floor elevations, columns, access openings, electrical distribution and material-transfer heights are checked before fabrication so the new machines can be installed without creating avoidable structural work or difficult maintenance points.

Compact Expansion Layout for an Existing Site

The approximately 1.35-acre site makes compact planning more valuable than simply increasing building area. Around 900 m² of additional production and warehouse space is used together with vertical equipment arrangement and outdoor bulk-storage positions. This allows the project to accommodate new processing capacity while preserving truck access, maintenance routes, finished-feed dispatch and safe movement around the existing operation.

1. Receiving and bulk-storage zone: positioned so ingredient trucks can unload without repeatedly crossing finished-feed dispatch routes.
2. Processing zone: uses vertical transfer between grinding, batching, mixing, pelleting and cooling equipment to reduce unnecessary horizontal conveying.
3. Warehouse and dispatch zone: separates bagged raw materials and finished feed while keeping loading access practical.

Bulk maize storage is sized from actual procurement practice rather than from an oversized generic silo specification. The number of storage days must balance seasonal purchasing opportunities against the limited expansion footprint and the capital tied up in inventory. Separate bins are provided where ingredients need individual control, while low-volume materials remain in dedicated bagged or micro-ingredient storage.

The production area uses natural and mechanical ventilation appropriate to the local climate, with localized cooling where electrical control rooms or sensitive components require it. General production buildings do not depend on unnecessary whole-building air-conditioning. Roof drainage, yard grading and stormwater routes are also considered because heavy seasonal rainfall can affect receiving, outdoor traffic and raw-material protection if drainage is poorly planned.

These decisions keep the poultry feed mill project compact without making the plant difficult to operate. Access around pellet mills, hammer mills, mixers and coolers is retained for inspection and wear-part replacement, because a tightly packed layout that cannot be maintained efficiently would reduce the value of the expansion.

Power Steam Water and Supporting Utilities

Utility planning follows the actual equipment load of the 20 T/H expansion. Electricity supplies the hammer mills, mixers, pellet mills, coolers, elevators, conveyors, screening equipment, bagging system, fans and auxiliary machinery. The electrical system is therefore sized from the final connected-load schedule and simultaneous operating demand, with starting characteristics of the larger motors considered when selecting distribution equipment.

Steam is required for conditioning pelleted feed, but the heat source is selected according to the client’s available energy supply, operating cost and local compliance requirements. The project is not tied to coal or to a fuel that may be unavailable at the site. Boiler capacity, steam pressure, condensate arrangement and water treatment are confirmed together with the final pelletizing system.

Variable-frequency control is used where changing speed provides a process or energy benefit, such as selected feeders, fans and conveying equipment. It is not added indiscriminately to every motor. This keeps the utility design practical while giving operators control where production rate or airflow genuinely needs adjustment.

A Lean Workforce for the Initial Operating Schedule

Approximately 20 employees support the initial operating arrangement. Because this is an expansion inside an existing business, the project does not need to duplicate every management and administrative position around the new line. Shared management, procurement and commercial functions can continue serving the wider factory, while the added workforce concentrates on production, raw-material handling, quality control, maintenance and dispatch.

• Production operators for receiving, grinding, batching, pelleting and packing.
• Warehouse and material-handling personnel for ingredients and finished feed.
• Maintenance personnel for mechanical and electrical routine work.
• Quality-control personnel for sampling, process checks and finished-feed verification.
• Shift supervision and essential support functions.

If the customer later extends daily operating hours, additional shift coverage can be added according to the actual operating plan rather than building an unnecessarily large permanent workforce at the first stage. Automation in batching, conveying and weighing reduces repetitive manual handling, but trained operators remain necessary for raw-material inspection, equipment monitoring, maintenance, cleaning and quality assurance.

RICHI Machinery provides commissioning and operational training around start-up and shutdown sequences, batching interlocks, pellet-mill adjustment, cooler operation, lubrication, inspection, routine maintenance and common fault handling. This helps the client move from equipment installation to stable commercial production with a team sized for the real operating schedule.

Dust Control Feed Safety and Environmental Measures

Environmental measures are integrated into the process without turning the project into an unnecessarily complicated treatment system. Dust-producing points at receiving, grinding, batching and packing use enclosed transfer and local aspiration connected to suitable filters. Equipment foundations, isolation and routine maintenance help control mechanical noise, while production areas are cleaned to prevent accumulated feed dust and spilled ingredients from becoming hygiene or safety problems.

• Pulse-jet dust collection at major dust-generating process points.
• Magnetic separation and raw-material cleaning before critical equipment.
• Defined handling of clean process fines and rejection of contaminated material.
• Stormwater routing and dry storage for ingredients and finished feed.
• Controlled waste, used lubricant and maintenance-material handling.

The feed process itself has limited direct wastewater generation. Water management therefore focuses on sanitation, domestic use, steam-system requirements and preventing contaminated runoff around receiving and storage areas. The result is a practical environmental configuration that supports reliable feed production without adding systems unrelated to the actual operation.

Why the Expansion Fits the Client’s Poultry Feed Business

A 20 T/H line is large enough to support commercial regional feed sales, yet the initial annual target of approximately 35000 tons prevents the business case from depending on immediate full utilization. This is particularly important for a feed manufacturer whose production schedule must follow customer orders, ingredient availability and changing feed formulas rather than simply operating continuously because machinery capacity exists.

1. Procurement flexibility: additional storage and ingredient segregation give the customer more options when purchasing maize, soybean meal and other feed materials.
2. Product flexibility: starter crumble and grower or finisher pellets can be produced through different downstream routes from the same core batching and mixing system.
3. Maintenance flexibility: parallel processing capacity reduces dependence on a single production route and makes planned maintenance easier to schedule.
4. Growth flexibility: longer operating hours can release additional output from installed equipment before another major expansion is required.

The commercial objective is therefore not to maximize tonnage on paper. It is to give the client enough capacity to serve existing customers, accept larger orders and develop new regional business while maintaining control over feed quality, ingredient inventory and production cost. That balance is central to the chicken feed mill expansion in Nigeria.

RICHI Scope for the Feed Mill Expansion

Expansion engineering begins with the parts of the factory the customer intends to continue using. Machine elevations, conveying routes, available bins, electrical capacity, building dimensions and maintenance access determine where new equipment can connect efficiently. RICHI then develops the new processing sections around the required throughput and product range rather than treating the project as an isolated equipment purchase.

• Process engineering and capacity balance for the 20 T/H expansion.
• Equipment selection for receiving, grinding, batching, mixing, pelleting, cooling, crumbling, screening and packing.
• Integration of new machines with usable existing factory infrastructure.
• Equipment layout, material-flow design and utility interface planning.
• Manufacturing, inspection and preparation for shipment.
• Installation guidance, commissioning and operator training.
• Maintenance planning and wear-part recommendations for long-term operation.

The animal feed factory project shows why expansion work requires more interface engineering than a stand-alone machine order. Every new conveyor, bin and processing machine must connect to the rest of the factory at the correct capacity, elevation and control sequence. A high-capacity pellet mill provides little benefit if upstream batching cannot feed it consistently or downstream cooling cannot receive its output.

By treating the project as one operating system, RICHI helps the customer use existing assets where they still create value while directing new investment toward the sections that increase throughput, reliability and production flexibility.

A Practical Route From Existing Capacity to the Next Stage of Growth

The completed chicken feed mill expansion in Nigeria gives the client a 20 T/H processing platform without requiring the entire existing factory to be discarded. Its initial annual production target of approximately 35000 tons leaves room for realistic utilization while providing sufficient hourly capacity for peak orders and future growth. The layout also allows the customer to increase operating hours as its poultry-feed market develops.

For customers planning a similar expansion, the most useful starting information is the existing poultry feed mill equipment list, building and equipment layout, current production capacity, formulas, ingredient forms, required pellet and crumble sizes, annual sales target, storage capacity, available electrical supply, steam conditions and packing specifications.

RICHI can then determine which existing systems can remain in service and where new animal feed production line equipment should connect. The objective is a balanced expansion in which receiving, storage, processing, utilities, labor and dispatch all support the same production target instead of creating hidden bottlenecks after installation.
