• The surface energy of the clinker covered with grinding aid(E) is the algebraic summation of E1,E2 and E3. E= E3 + E2 + E3 11-05-2015 Indian Institute of Technology,Delhi 13 14. • If E = -ve that means the energy is released and the grinding aid spreads out on clinker's surface.
Cement Grinding Aid : Grinding Aid that enhances early strength of cement. Reduces/ Remove electrostatic attraction between broken particles in the mill, thus making more energy available for grinding. Allows the tri-calcium silicate reaction to begin sooner than normal, thus resulting in significantly higher early age strength

In mineral beneficiation, grinding is also the most energy~onsuming process. Energy consumed in ore grinding in various mills as compiled by Hartley et al. [2] is shown in Table 1. It is to be noted that the energy consumed in grinding alone represents up to 70% of the energy for the whole beneficiation process (see Table 2 reproduced from a 1934

grinding raw or cooked meats, firm vegetables, dried fruits and cheese. Fine Plate ΠUse for grinding raw meat, cooked meats for spreads and breadcrumbs. Grinding Meat ΠFor better mix and more tender results, grind beef twice. Best texture results from grinding very cold or partially frozen meat. Fatty meats should be ground only once.
The nature of grinding aids means that they promote the formation of dust because they reduce the agglomeration of the finest particles (see Figure 3). In certain cases, the filter and/or the hopper of the bag filter can become overloaded. This can lead to the wrong supposition that the grinding aid chemically attacks the filter cloth.
