Size reduction. Zeki Berk, in Food Process Engineering and Technology, 2009. Energy consumption. As a rule, size reduction operations are heavy in energy consumption (Loncin and Merson, 1979; Hassanpour et al., 2004).As an example, the cost of energy is the single largest item in the total cost of wheat milling. Milling of one bushel (approx. 27 kg) of wheat requires kwh of electric ...

Over the years, alternative procedures to the Bond grindability test have been proposed aiming to avoid the need for the standard mill or to reduce and simplify the grinding procedure. Some of them use the standard mill, while others are based on a nonstandard mill or computation techniques. Therefore, papers targeting to propose a better alternative claim to improve validity, to reduce test ...

Particle Size. Classical dry sieving is the preferred method when the required measuring range lies between roughly 40 microns and 125 mm. As shown in Figure 1, the range may be extended to 10 microns by air jet sieving and to 20 microns by wet sieving. Figure 1. Measuring range of air jet, wet and dry sieving.

A sieve shaker is a helpful instrument in the sieving method. They do not have a fixed shape or size and can vary from a teaspoon in the kitchen to a relatively larger sand sieve shaker in the sand mining industry. They are used to ensure that sieving is carried out smoothly without the sieve pores getting blocked by larger particles.

In a flour mill, the impurities are removed from wheat before grinding,by process of sieving. A bagful of wheat is poured on a slanting sieve made of iron mesh. The wheat grains pass through the Sieve whereas pieces of stone,stalk and husk are left behind. (3) Fine sand is obtained by method of sieving.
