Screen machines belong to the ancillary equipment in mining machines. High frequency screen is often used for removing the impurities on the surface of the final products. Such screen machines have widely applications in mining industry, construction industry, chemical industry as well as metallurgy industry. Screen machines have many different types, such as high frequency screen, high efficiency screen and so on.

El enorme impacto económico como resultado de la mejora de la productividad significa que el tiempo de retorno de la inversión suele ser muy corto.Esto asegura un flujo constante de material a través de la estación primaria a las etapas de proceso siguientes.El tiempo de inactividad debido a acumulaciones y bloqueos puede reducirse fácilmente al mínimo.La producción a largo plazo de la planta se mejora significativamente cuando la estación primaria está equipada con una solución de roca.
Kerosene as a modifier in the presence of amine collector depresses dolomite [11,27]; however, conventional depressants for dolomite are sodium silicates [7,11] and sodium hydroxide (both can be used as pH regulators) .Various investigations have indicated that flotation of Mg carbonates poses several difficulties where the fatty acids and their derivatives, which are used as collectors, have a poor selectivity for carbonates and phosphate minerals . On the other hand, Mg carbonates cause adverse effects on the flotation of their associated valuable minerals; therefore, their depression is a growing procedure in the mineral processing industry. Owing to the significant content of cations (Ca2+ and Mg2+), organic and inorganic depressants can adsorb on the surface of dolomite .
4 and plasticity Index PI: 26. Overall, it was categorized as poor for subgrade. Figure 17 shows the dry density versus moisture content for soil with 0%, 10% and 20% soil addition. As shown in Table 7, the dry density increased as the CSF rate increased while the required moisture in order to reach the maximum dry density reduced. Both of these properties are desirable for soil stabilization, but the most significant increase is that of the load-bearing capacity of soils, expressed by the CBR value. A similar strength increase has been reported (at lower addition percentages) when using lime for soil improvement [42,43].The soil used as a reference had the chemical composition shown in Table 6, while its Atterberg limits were as follows: liquid limit LL: 56, plastic limit PL: 29.6. Furthermore, a higher percentage of CSF increased the CBR value even more.
