Design and Fabrication Of Hammer Mill Mechanical Project

The hammer mill is an impact mill employing a high speed rotating disc, to which are fixed a number of hammer bars which are swung outwards by centrifugal force. Material is fed in, either at the top or at the Centre, and it is thrown out centrifugally and crushed by being beaten between the hammer bars, or against breaker plates fixed around the periphery of the cylindrical casing.

4/12/2016· The hole fits onto a rod inside the hammer mill and swings to hit the material. The hammer design of hammer mill is determined by operating parameters such as rotor speed, motor horsepower, and open area in the screen. Optimal hammer design and placement will provide maximum contact with the feed ingredient.

Study of the Process, Design and Operating Parameters

the design, operating and process parameters were analyzed. Conclusions: Hammer design (number of . hammers, hammer thickness, distance . and angle between adjacent hammers) is a critical parameter that affects the velocity distribution of the cuttings inside of the process mill and the efficiency of the mill.

Effects of mill design and process parameters in milling

7/1/2015· The hammer mill used in this study is manufactured by Fitzpatrick (Fig. 3(a)). The blades of the hammer mill pulverize particles along their rotational path. The shape of hammers is shown in Fig. 3(d). As shown in Fig. 1(b), the tips of the blades create a narrow region of intense shear near the surface of the screen. The screen size in this setup has less importance because the shearing is mostly being

Hammer Wikipedia

A hammer is a tool consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nails into wood, to shape metal, or to crush rock. Hammers are used for a wide range of driving, shaping, and breaking applications. The modern hammer head is typically made of steel which has been heat treated for hardness, and the handle is typically made of wood or plastic. The claw hammer
