Development And Performance Evaluation of a Cost-Effective Horizontal Pulverizer for Small-Scale Agricultural Processing

This study presents a horizontal cylinder pulveriser designed for small-scale applications, achieving a 100 kg/h throughput with a 2 HP motor at 2800 rpm. Fabricated using mild steel and stainless steel, the machine ensures durability and food-grade compliance. Performance tests on grains and crop residues showed 85% efficiency, ≤1 mm particle size, and low vibration (<1.2 mm amplitude). Stress and vibration analyses confirmed structural stability, while a cost analysis (₹32,785) highlighted affordability. Compared to hammer and roller mills, the design offers superior energy efficiency (5.4 kWh/ton), reduced vibration, and easier maintenance. The optimized configuration suits agricultural and light industrial applications, with potential for enhancements like wear-resistant coatings and IoT monitoring.
