They used an indirect method of ... increase in power demand of knife mill [13]. Yang et al. [24] fitted the particle size distribution data of alfalfa
for milling to obtain small particles is relatively high. Higher power was consumed for fine grinding corn and grain sorghum by hammer mill (Martin and Behnke, 1984), The relationship for grinding energy with the length of wood cubes, the grinding energy increased greatly as the particle size is reduced (Holtzapple et al., 1989).
The study of project deals with the hammer mills employing a high speed rotating disc, to which an ''n'' number of hammer bars are fixed and swung outwards by centrifugal is fed in, either at the top or at the Centre, and it is thrown out centrifugally and crushed between the hammer bars or against breaker plates fixed around the periphery of the cylindrical casing.

DESIGN, FABRICATION AND TESTING OF A LABORATORY SIZE HAMMER MILL AJAKA and ADESINA A. Department of Mining Engineering School of Engineering and Engineering Technology The Federal University of Technology, Akure, Nigeria ABSTRACT: The laboratory size hammer mill was fabricated from locally available materials
increasing power requirements. The design improves access to working parts simplifying screen changes. The center feed and fully symmetrical rotors distribute the product across the full width of the screen area for even hammer wear, this allows the rotor to be reversed so that both edges of the hammers can be utilized before replacement is ...

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case".
Optimal hammer design and placement will provide maximum contact with the feed ingredient. Hammer mills in which the rotor speed is approximately 1,800 rpm, should be using hammers which are around 25cm (~ 10 inches) long, (~ inches) wide, and ( inches) thick.
