In general, Bond's work index is used to determine the grinding efficiency and also to calculate the power requirement. The process is very time consuming and it requires skilled labor and specialized mill. A systematic investigation was carried out to predict Bond's work index using simple field measurable properties of rocks.

Colour index finding indicated better whiteness index, i.e. 82.29–81.11 for hammer-milled and 80.96–77.18 for attrition-milled samples. From the study, it may be concluded that attrition mill was not appropriate for making the tamarind seed powder, while hammer mill was the most suited.

Seeking a more plentiful …

The samples used in this work are either routinely co-fired in coal fired power plants or have been used in biomass co-firing trials, as illustrated in Fig. 1.Portuguese wood pellets (mainly pine with a small amount of eucalyptus), Spanish olive cake (a residual waste mix from olive oil production formed of powdered olive pulp (0–850 μm), olive pips (850–3350 μm) …

The work index is the comminution parameter that expresses the resistance of the material to crushing and grinding. In the case of the HammerMaster and LimeMaster crushers, McLanahan has designed the crusher with rotor dimensions, shaft and bearings to handle a variety of applications at a specific horsepower rating.

Size Reduction. Kk = 7.26 KW/ (Kgls) So energy required to crush 85 mm to 15 mm E = 7.26 in (85/15) E = 12.5 KJ/kg. 2.6 FACTORS AFFECTING SIZE REDUCTION It include 1. Hardness It is a surface ...

A hammer can do many things (drive a nail, stop a door, kindle a fire, bang a gong), but its features enable (or, in the language of design, "afford") certain uses, and through that enablement continue to suggest uses, and by extension ways of thinking and seeing the world.

The tested designs of the hammer mill differed mostly in the shape of the hammers. A characteristic shape indicator was the hammer angle (α). In the experiment, the design of a standard rotor (α ...
