The development of a mill pulveriser incorporates the design of a hammer mill and a blower. A hammer mill is a type of crusher, which can be used for grinding rock, forage, grains or other large size particles into smaller pieces by the repeated blows of little hammers. It is designed to convert larger pieces of material into smaller particle ...

The type of hammer mill introduced to Uganda 60 years ago is still prevalent in the milling of maize and sorghum (Independent Consulting Group, 2003). These hammer mills are highly inefficient (USAID, 2010). Hammer mills are very important in Uganda and neighboring countries as a time and costeffective means of milling grains.

The working principle of the hammer mill is simple to understand. The principle is illustrated in Fig. 1 (a). It only requires choosing an appropriate motor, crushing hammers/knives and material to be crushed. It operates on the principle of impact between rapidly moving hammers mounted on the rotor and the stationary powder bed.

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 ...
