The final results indicated that the new hammer produced a highest percentage of fine crushed particles compare with original one. The wear rates were g/h and g/h for the original and new hammer respectively. This means that wear rate decreased by about 38% when replaced the redesigned hammer instead of the original one.

With the aim of scalingup the hammer mill, Kwon et al. [13] established an empirical mathematical relationship between the mill production rate and design/operating parameters (rotor diameter and speed, size of the feed material, and desired product size), which could be used as a tool for mill design and throughput prediction.

Abstract. In hammer mills, the grinding process consists of hitting the material by hammers, articulated on a rotor. It is important, however, that the percussions applied to the hammer are not transmitted to the articulation. The position of the hammer articulation should be determined so that the percussion given by the collision with the ...
