6–7 T/H Corn Maize Hammer Mill in Nigeria

The purpose of this investment was to improve the grinding process of raw maize into fine powder suitable for animal feed, corn flour, and industrial applications.

The client’s existing production line remained operational, but the SFSP66*80 hammer mill would serve as a dedicated high-efficiency crusher machine, complementing the rest of their equipment. This strategic purchase allowed them to enhance throughput without overhauling the entire production facility.

Client Profile and Purchase Motivation

The client is an agro-processing company focused on:

• Production of poultry and livestock feed
• Maize flour production for local markets
• Supply of maize meal for industrial starch and bioethanol manufacturers

Their decision to purchase a single SFSP66*80 hammer mill was based on several factors:

• The need to grind large volumes of maize efficiently (6–7 T/H)
• Desire for consistent powder size (0.5–2 mm) suitable for feed production and maize flour processing
• Reduction in downtime and energy consumption compared to older machines
• Ease of maintenance and long service life

By investing in this standalone hammer mill, the client could maintain flexibility in their production line while significantly improving efficiency and product quality. The machine was intended for use primarily during peak maize harvest months, ensuring that the company could handle high volumes of raw material without compromising output quality.

Equipment Selection and Specifications

After assessing the client’s raw material characteristics and production goals, RICHI Machinery recommended the SFSP66*80 model. Key specifications of this hammer mill include:

• Rotor diameter: 660 mm
• Crushing chamber width: 800 mm
• Rotating speed: 2980 rpm
• Hammer line speed: 103 m/s
• Motor power: 75 kW
• Expected maize throughput: 6–7 T/H

The crusher was equipped with customizable sieves, enabling the client to produce maize powder with particle sizes ranging from 0.5 mm to 2 mm. This flexibility allowed the client to target multiple product lines, from fine corn flour to coarser feed materials.

Raw Materials and Processing Goals

The client primarily processes locally grown maize, sourced from Kaduna and neighboring states. The raw maize characteristics include:

• Kernel moisture content: 12–14%
• Size range: 0.5–2 cm per kernel
• Hardness: medium to hard, typical of Nigerian maize varieties

The SFSP66*80 hammer mill was selected for its ability to:

• Handle medium-hard maize kernels without jamming or excessive wear
• Produce consistent particle sizes suitable for various feed formulations
• Operate continuously with high energy efficiency

Processed maize powder serves multiple purposes for the client:

• Animal feed: Fine maize powder is a key ingredient in poultry, pig, and cattle feed. Uniform particle size ensures better feed mixing, higher digestibility, and improved livestock growth rates.
• Corn flour: Powdered maize is used to produce maize meal and traditional Nigerian foods such as pap (ogi) and tuwo. Consistency in particle size enhances cooking performance and texture.
• Industrial uses: Maize powder is sometimes supplied to starch processing plants and bioethanol manufacturers, requiring precise particle size for optimal downstream processing.

By standardizing the maize powder, the client ensures product quality and consistency for local markets and industrial clients.

Transportation and Logistics

The SFSP66*80 hammer mill was shipped via sea freight from China to the Port of Lagos, Nigeria’s primary commercial port. Upon arrival, RICHI Machinery coordinated local transport to Kaduna state. The installation process included:

• Assembly and alignment of the hammer mill
• Training operators on safe usage and routine maintenance
• Integration with the existing maize storage and conveyor system

The client reported that RICHI’s professional guidance during installation minimized operational disruptions, allowing them to achieve full production capacity quickly.

Operational Benefits and Client Feedback

“The SFSP66*80 hammer mill has transformed our maize processing operations. We now produce uniform maize powder consistently, which has improved the quality of our animal feed and corn flour. Maintenance is straightforward, and the machine runs quietly with minimal vibration. RICHI’s installation and training support were excellent, making the transition seamless. This machine is a reliable investment that has enhanced our production capacity.”

Additional operational advantages include:

• 20–25% increase in throughput compared to previous crushers
• Stable power consumption with minimal fluctuation
• Reduced downtime and longer hammer lifespan due to reversible rotor design
• Versatility to process other grains and feed ingredients as needed

Technical Features and Advantages

The SFSP66*80 hammer mill is equipped with advanced technology that ensures high efficiency and reliability:

• Water-drop-shaped crushing chamber: Enhances secondary crushing and maintains consistent particle size
• Patented rotor-end air inlet system: Improves small-diameter kernel processing and prevents blockages
• Adjustable sieves and pressure plates: Allow precise control over particle size, easily adapted for feed, flour, or industrial applications
• Reversible rotor design: Extends hammer life and reduces maintenance frequency
• High-precision rotor balancing: Minimizes vibration and noise, enhancing operator comfort and safety
• User-friendly maintenance: Movable operation doors and interlocked safety devices simplify inspections and cleaning

These features make the SFSP66*80 a versatile and reliable machine for maize processing in Nigeria.

Versatility and Industry Applications

While this project focuses on maize, the SFSP hammer mill is versatile enough to process:

• Other cereals such as sorghum, wheat, and millet
• Livestock feed ingredients like soybean and cassava chips
• Agricultural residues like rice husks for feed or industrial use

Its ability to handle multiple raw materials and produce adjustable particle sizes makes it an ideal choice for agro-processing companies seeking flexibility and efficiency.

Conclusion

The corn maize hammer mill in Nigeria project illustrates how investing in a standalone SFSP66*80 hammer mill can enhance production efficiency, product quality, and operational flexibility. Key benefits for the client include:

• Consistent maize powder size (0.5–2 mm) for feed, flour, and industrial applications
• Increased throughput (6–7 T/H) and reduced downtime
• Lower energy consumption and longer hammer lifespan
• Ability to process multiple raw materials and adapt to market demands

RICHI Machinery’s professional support, including installation, training, and technical consultation, ensured that the client could maximize the benefits of their investment. The project demonstrates why Nigerian agro-processors trust RICHI hammer mills for efficient, high-quality maize processing.

This case highlights RICHI’s reputation for reliable equipment and exceptional service, making it clear that investing in their hammer mills is a strategic move for businesses aiming to enhance productivity and product quality.
