8–10 T/H Corn Maize Hammer Mill in Kenya

The purchase of this single SFSP66*100 animal feed hammer mill was strategically motivated by the company’s need for improved crushing efficiency, consistent particle size, and reduced energy consumption.

By investing in a high-quality hammer mill, the client aimed to increase production efficiency during peak maize supply months, ensure uniform feed and flour quality, and expand their operational flexibility to process other grains in the future.

Client Profile and Purchase Motivation

The client is a privately owned agro-processing enterprise that specializes in:

• Production of poultry and livestock feed
• Maize flour and meal production for local markets
• Supply of maize-based products for industrial processing

The primary motivation for purchasing a standalone SFSP66*100 hammer mill was:

• High-capacity maize grinding: The client needed to process 8–10 T/H of raw maize efficiently.
• Consistency in particle size: Fine maize powder (0.5–2 mm) was necessary for feed mixing and flour processing.
• Operational reliability: The client sought a robust, low-maintenance machine to minimize downtime.
• Flexibility: The ability to process different raw materials, such as sorghum, millet, and rice bran, in addition to maize.

Investing in this standalone hammer mill enabled the client to maintain operational continuity while significantly boosting maize powder production. The decision to purchase only a single unit was deliberate: it allowed for immediate improvement without the complexity of integrating multiple new machines into the existing line.

Equipment Selection and Specifications

RICHI Machinery recommended the SFSP66*100 model based on the client’s production requirements and raw material characteristics. The key specifications of the hammer mill are:

• Rotor diameter: 660 mm
• Crushing chamber width: 1000 mm
• Rotating speed: 2980 rpm
• Hammer line speed: 103 m/s
• Motor power: 90 kW
• Expected maize throughput: 8–10 T/H

The feed crusher machine features customizable sieves that allow the final maize powder to range from 0.5 mm to 20 mm. For this project, the client opted for a 1–2 mm sieve, producing fine powder suitable for both feed and maize flour production. The SFSP66*100’s high rotor speed and optimized hammer arrangement ensure uniform particle size, high efficiency, and minimal energy waste.

Raw Materials and Processing Goals

The client sources maize from local farmers in Nakuru, Uasin Gishu, and neighboring counties. The raw material characteristics include:

• Kernel size: 0.5–2 cm
• Moisture content: 12–14%
• Hardness: medium, typical of Kenyan maize varieties

The hammer mill was selected to handle medium-hard maize kernels efficiently, producing uniform powder without excessive wear or clogging. This allows the client to supply consistent quality products to:

• Animal feed: Fine maize powder ensures better mixing with other feed ingredients, improves digestibility, and enhances poultry growth rates.
• Maize flour: Powdered maize is processed into flour for staples like ugali, porridge, and traditional cakes. Consistency in particle size ensures proper cooking and texture.
• Industrial applications: Fine maize powder can also be supplied to starch, ethanol, and brewing industries.

By standardizing the maize powder, the client can meet multiple market demands and maintain a competitive edge in Kenya’s growing agro-processing sector.

Transportation and Logistics

The SFSP66*100 hammer mill was shipped via sea freight from China to the Port of Mombasa, Kenya’s main seaport. RICHI Machinery arranged for local transport from Mombasa to Nakuru County, including loading, unloading, and secure handling. During installation, RICHI’s team provided:

• Assembly and alignment of the hammer mill
• Operator training for safe operation and routine maintenance
• Integration with the existing maize storage and conveyor system

The client highlighted that the professional support provided by RICHI Machinery minimized operational downtime and ensured the machine reached full production capacity quickly.

Operational Benefits and Client Feedback

“The SFSP66*100 hammer mill has completely transformed our maize operations. We now produce high-quality maize powder with consistent particle size, which has improved both our feed and flour products. The machine runs smoothly, with minimal noise and vibration. Maintenance is straightforward, and the RICHI team provided excellent guidance during installation. We are very satisfied with our investment.”

Other notable operational benefits include:

• Throughput increase of approximately 25% compared to the older hammer mill
• Stable power consumption with minimal fluctuations
• Reversible rotor design, extending hammer life
• Versatility to crush other grains like sorghum, millet, and rice bran

Technical Features and Advantages

The SFSP66*100 hammer mill incorporates several advanced features:

• Water-drop-shaped crushing chamber: Enhances secondary crushing and ensures uniform particle size
• Patented rotor-end air inlet system: Prevents blockages and improves throughput of small-diameter kernels
• Adjustable sieves and pressure plates: Enable precise control over powder size for feed, flour, and industrial applications
• Reversible rotor design: Reduces hammer wear and maintenance needs
• High-precision rotor balancing: Minimizes vibration and noise for operator comfort
• User-friendly maintenance: Movable operation doors and safety interlocks simplify inspections and cleaning

These technical innovations ensure high efficiency, reliability, and low operating costs, making the hammer mill a versatile solution for various raw materials.

Versatility and Industry Applications

Although the project focused on maize, the SFSP hammer mill is highly versatile and capable of processing:

• Cereals such as sorghum, wheat, millet, and rice
• Livestock feed ingredients like soybean, cassava chips, and rice husks
• Agricultural residues for industrial uses or feed supplementation

Its broad adaptability makes it a reliable choice for agro-processing companies that require flexibility in raw material handling and product outputs.

Conclusion

The corn maize hammer mill in Kenya project demonstrates how investing in a standalone SFSP66*100 hammer mill can transform maize processing operations. Key advantages for the client include:

• Production of consistent maize powder (0.5–2 mm) suitable for feed, flour, and industrial applications
• Increased throughput (8–10 T/H) with reduced downtime
• Lower energy consumption and longer hammer lifespan
• Capability to process multiple raw materials for diverse applications

RICHI Machinery’s professional services, including installation, training, and technical support, ensured the client could achieve optimal results with minimal operational disruption. This case underscores RICHI’s commitment to high-quality equipment and customer-focused solutions, making their hammer mills a strategic investment for any agro-processing enterprise in Kenya or similar markets.
