5–6 T/H Maize Grain Hammer Mill Crusher in Nigeria

The decision to purchase a standalone unit, rather than an entirely new production line, allowed the company to integrate the hammer mill into their current setup without disrupting operations.

This strategy enabled immediate productivity improvements while keeping investment costs manageable. The new hammer mill would become the primary milling machine for maize flour production and feed ingredient preparation, ensuring consistent particle size and optimizing downstream pellet pressing and mixing processes.

Client Profile and Purchase Motivation

The client is a mid-sized feed mill operator serving local poultry and livestock farmers. Their main operations include:

• Producing high-quality feed for broilers, layers, and piglets
• Processing maize and other cereals into flour and mash
• Supplying animal feed ingredients for both local and regional markets

The primary motivation for purchasing the maize grain hammer mill crusher was to increase throughput, improve milling uniformity, and ensure consistent feed quality. The client required a machine that could handle 5–6 tons per hour of maize kernels and produce a finely ground product suitable for poultry feed mash and premixes.

By purchasing a single hammer mill, the client could continue using existing silos, mixers, and conveyors while upgrading the core milling component. This approach allowed the client to focus capital investment on equipment that would immediately impact production efficiency and product quality.

Equipment Selection and Specifications

After technical consultation with RICHI engineers, the client selected the SFSP66*60 water-drop hammer mill for their maize milling needs. The machine specifications were tailored to the client’s throughput and material characteristics:

• Rotor diameter: 660 mm
• Crushing chamber width: 600 mm
• Rotating speed: 2980 rpm
• Hammer line speed: 103 m/s
• Motor power: 75 kW
• Estimated maize throughput: 5–6 T/H

The SFSP66*60 maize grain hammer mill crusher in Nigeria features a water-drop-shaped crushing chamber, patented rotor-end air inlet system, and customizable sieve plates, allowing the client to adjust the final maize flour size between 0.5–3 mm. These features provide a high-efficiency milling process, stable power consumption, and minimal material recirculation.

Raw Materials and Processing Goals

The client’s primary raw material is maize, specifically:

• White and yellow maize kernels from local farms
• Moisture content: approximately 12–14%
• Some broken maize kernels from local storage and post-harvest processing

The SFSP66*60 maize grain hammer mill crusher in Nigeria allows the client to crush maize kernels into consistent flour suitable for both feed mash and premixes. By controlling particle size, the client can enhance feed digestibility, improve pellet binding in downstream pressing processes, and achieve uniform mixing of feed ingredients.

The uniform maize flour produced by the hammer mill also reduces waste during pellet pressing and ensures consistent feed texture, which is essential for poultry growth performance.

Transportation and Logistics

The maize grain hammer mill crusher machine was shipped from RICHI’s manufacturing facility in China via sea freight and arrived at the Port of Lagos, Nigeria. RICHI coordinated logistics, including customs clearance, inland transport, and on-site installation at the client’s facility. The engineering team supervised equipment assembly, rotor alignment, and operator training.

The client noted that the RICHI team’s technical support made the commissioning process smooth, ensuring the hammer mill began operation immediately upon arrival. Their operators were trained to adjust sieve plates, monitor motor load, and conduct routine maintenance efficiently.

Operational Benefits and Client Feedback

“The SFSP66*60 maize grain hammer mill crusher has transformed our milling process. Our throughput increased to 5–6 tons per hour, and the maize flour size is consistent across all batches. This has improved our pellet quality and reduced machine downtime. The hammer mill runs quietly and with minimal vibration, making it much easier to operate. RICHI’s support during installation and training was excellent, and we feel confident in using the equipment daily.”

Additional benefits include:

• Consistent flour size between 0.5–3 mm, ideal for feed mash and premix production
• Increased processing efficiency compared to older mills
• Reduced energy consumption and improved motor efficiency
• Ability to process both whole and broken maize kernels
• Enhanced feed pellet quality due to uniform maize flour

Technical Features and Advantages

The SFSP66*60 hammer mill offers advanced technical features suitable for maize milling:

• Water-drop-shaped crushing chamber: Improves secondary crushing efficiency and ensures uniform particle size
• Patented rotor-end air inlet system: Increases output of fine maize flour by over 20%
• Adjustable sieves and pressure plates: Allow precise control of final particle size
• Reversible rotor operation: Extends hammer lifespan and reduces maintenance
• High-precision rotor balancing: Minimizes vibration and noise
• Safety interlocks and movable operation doors: Facilitate maintenance and protect operators

These features enable the hammer mill to deliver consistent quality maize flour, maintain long-term operational reliability, and support a wide range of feed production requirements.

Versatility and Industry Applications

Although the machine was purchased primarily for maize milling, its versatility allows the client to process other grains and materials:

• Sorghum and millet: Suitable for local livestock feed production
• Soybeans and other legumes: For inclusion in protein-rich feed premixes
• Agricultural residues: Such as maize cobs and husks, which can be ground for bedding or biomass applications

This versatility allows Nigerian feed mills to respond to variable raw material supply and maintain consistent product quality.

Conclusion

The maize grain hammer mill crusher in Nigeria illustrates the advantages of integrating a standalone SFSP66*60 hammer mill into an existing feed production facility. Key outcomes include:

• Throughput of 5–6 tons per hour for maize kernels
• Uniform particle size between 0.5–3 mm for feed mash and premixes
• Enhanced pellet pressing performance and feed quality
• Energy-efficient operation with minimal downtime

With professional support from RICHI Machinery during installation and operator training, the client successfully upgraded their milling operations. The investment in the maize grain hammer mill crusher has proven cost-effective, delivering immediate operational improvements and long-term reliability.
