Hammermills accomplish size reduction by impacting a slow moving target, such as a cereal grain, with a rapidly moving hammer. The target has little or no momentum (low kinetic energy), whereas the hammer tip is travelling at a minimum of 16,000 feet per minute (4,880 m/min) and perhaps in excess of 23,000 feet per minute (7,015 m/min) (high kinetic energy).

Optimizing hammermil performance. Predrag Stamenkovic. 1. Introduction We have no less than 6 (six) Vodnany hammermills. Total applied power is almost one megawatt of electricity: 2 x 250kW + 4 x 110kW = 940kW. There is a rule for straw milling, which states the approximate consumption of 20 kilowatts per hour and ton, meaning that our ...

Keywords: Blender, Harmer, Mill, Multipurpose, Machine INTRODUCTION Hammer mills, as the name implies, are mills for grinding grains into powder by impact [1]. The materials are poured into a loading hopper at top of the hammer mill, and inflow is controlled by a small gate designed to allow the grains enter into the grinding chamber [24].

At high feed rate the drop in the generation of fines is associated with inadequate comminution of the particles. The influence of the operating variables, as seen from the above discussion, indicates that a relatively lower feed rate and a moderately high rotor speed would be ideal for achieving the best performance of the hammer mill.
