2-10T/H Maize Grinding Hammer Mill in Nigeria

Client Profile and Motivation

The client is a medium-scale agribusiness specializing in poultry and cattle feed production. Their primary objectives for purchasing the SFSP66*100 maize grinding hammer mills included:

• Efficient processing of maize kernels, cobs, husks, and stalks into uniform powders
• Producing high-quality raw materials for feed and biomass pellets
• Reducing wastage from maize by-products and adding economic value
• Ensuring the flexibility to test different maize-based feed formulations before committing to larger production lines

By choosing standalone hammer mills, the client could maintain ongoing operations without disruption while gradually increasing production capacity. The flexibility to switch raw materials and particle sizes ensures adaptability to the varying feed demands across different livestock types.

Equipment Selection and Specifications

Based on the client’s raw material characteristics and processing goals, the SFSP66*100 maize grinding hammer mills were chosen with the following specifications:

• Rotor diameter: 660 mm
• Crushing chamber width: 1000 mm
• Rotating speed: 2980 rpm
• Hammer line speed: 103 m/s
• Power: 110 kW per unit
• Production capacity:
  • Grains: 8–10 T/H
  • Straw/stalks: 2–2.5 T/H
  • Wood chips or other fibrous residues: 2–2.5 T/H

These machines are designed with an advanced water-drop-shaped crushing chamber, which optimizes secondary crushing and increases throughput by 25% compared to conventional hammer mills. The adjustable sieve plates allow customization of the final particle size from 0.5 mm to 20 mm, giving the client the versatility to produce maize flour for feed, biomass powders, and fibrous materials for bedding.

Raw Materials and Processing Goals

In Nigeria, maize by-products are abundant and underutilized. The client primarily processes:

• Maize kernels: Main ingredient for poultry and cattle feed
• Maize cobs: Pulverized into 2–4 mm powders for feed fiber or biomass pellets
• Husks and stalks: Processed into 3–5 mm fibrous powders for feed enrichment and biomass energy

The SFSP66*100 hammer mill crusher machines allow the client to:

1. Grind maize kernels into 1–2 mm fine powder for feed pellet production
2. Process cobs and husks into medium-fine powders suitable for fiber inclusion in feed or biomass pellets
3. Pulverize maize stalks for livestock bedding or coarser feed mixes

The adjustable sieve system ensures consistent particle size, improving feed pellet quality, reducing wear on subsequent processing equipment, and maximizing energy efficiency.

Operational Benefits and Client Feedback

After commissioning, the client reported multiple operational improvements:

• Stable throughput of 8–10 T/H for maize and 2–2.5 T/H for by-products
• Consistent particle size, improving feed pellet density and digestibility
• Reduced energy consumption due to the optimized hammer line speed and airflow design
• Easy switching between raw materials through adjustable sieves
• Low maintenance and extended hammer life due to reversible rotor design

"The SFSP66*100 maize grinding hammer mills have transformed our processing operations. We can now efficiently grind maize and by-products into uniform powders suitable for feed and biomass pellets. RICHI's installation and training services made it simple to start production immediately. These machines are reliable, versatile, and easy to maintain."

This feedback emphasizes the practicality and reliability of standalone hammer mills, which meet current production demands while allowing future scalability.

Transportation and Logistics

The two SFSP66*100 maize grinding hammer mills were shipped via sea freight to the Port of Lagos, the primary industrial port in Nigeria. RICHI Machinery provided comprehensive logistics support, including customs clearance and inland delivery to Kaduna. The client appreciated the turnkey shipping and on-site installation services, which minimized operational downtime.
