On the other hand, fine coal might be unwanted; it all depends on the coal, the market and the decision makers. Each technology in use for the processing of fine coal therefore has its own place in the process ...

Fine particles (PM 2.5) can reduce atmospheric visibility by scattering or absorbing solar radiation (Peng et al., 2016; Cai, Li, Liao, Wang, and Wu, 2017), and affect cloud formation by acting as cloud condensation nuclei (Rosenfeld et al., 2008; Seinfeld et al., 2016).Fine particles can also act as an interface for heterogeneous reactions by providing large surface area and …

2 CEMENT INDUSTRY IN ALGERIA The first cement plant in operation in Algeria was a small wet processing plant which dates back to 1901 with an annual production capacity of 50 000 tonnes/year which was later modernised. Until 1962, there were three cement plants with a total annual capacity as low as 800 000 tonnes and hence a

Fine particles (diameter < 0.5 mm) are residual particles of native semolina, or small wet particles generated by erosion mechanisms of larger agglomerates.-Wet nuclei (0.5 < diameter < 0.8 mm).-Wet agglomerates (0.8 < diameter < 2 µm) are the desired structures and will give the couscous grains.-Large pieces of "dough" (2 mm < diameter).

Especially the production of fine powders by reduction under H 2 atmosphere is not possible after the state of the art. To solve the problems the granulation of the oxide powder and a two-step heat treatment process was developed [10].

Our STEINERT wet drum magnetic separators are used in the fine grain range from 1 µm up to 3000 µm (0.001 mm – 3 mm) to separate magnetic particles from process liquids, sludges or emulsions. Their strong magnetic fields enable the efficient separation of magnetite or ferrosilicon from the wet medium.

For bulk synthesis of fine particles under dry conditions, not only dry grinding as a top-down method but also dry mechanochemical process as a bottom-up method are an effective choice. In both cases, the improvement of energy consumption and productivity is a very important problem and the efficiencies must be sufficiently increased.
