Particles that are bigger than the apertures in the screens are retained, and constitute the oversize.Screening can be defined as a mechanical operation which separates particles as outlined by their sizes and their acceptance or rejection by openings of a screening face. There are lots of diverse types of industrial screens, which may perhaps be divided into stationary and moving screens. Conversely, these which are smaller pass through the screening surface, forming the undersize.

HPC cone crusher is one kind of crushing device in SBM Company, it is very suitable for processing medium hard or hard mineral ores, such as iron ores, concrete, bauxite, quartz, slag and so on. its crushing chamber specially designed according to particles sink principal and its matching speed can sharply increase the crushing ratio , improve the quality of final particles.

Chromite is conveniently milled to recover a fine concentrate by gravity and elutriation techniques. The fines may be agglomerated at the smelters, either by briquetting or using the Outokumpu pelletisation and preheating system, to reduce the amount of lumpy ore and chip required. However, ferrochrome furnaces need a porous charge so lumpy ore and chips must also be recovered by dense medium separation to mix with the fines. Further gravity separation and elutriation steps yield the specific grain sizes and reduced levels of impurities, such as silica, required for the chemical and foundry sand markets.

The material screening device is a material screening structure. It is mainly used as that when the materials have reached the standard, they will be sent from sand washing machine by the screening device. The other parts will again enter be washed under its action, and ultimately achieve the qualified material granularity.

After addition of the solution, the contents of the mill were plugged for 10 minutes. Balls began forming during water addition.08 pounds of a 50% NaOH solution (3% dosage) was added to the pugger over a period of 5 minutes by means of a separatory funnel. 1250 cc. of water was gradually added to the charge over a period of 15 minutes while pugging. After addition of water was completed, the pugger was maintained in operation for 30 minutes, resulting in complete conversion of the fines into dust-free balls, having the following screen analysis. The pugger was started and 1.Twenty-five pounds of ground minus 60 mesh Demerara bauxite ore was charged to a pug mill.

Furthermore, BR application in the soil also provides essential nutrients to the plants and increases the concentrations of Zn and Mn [16]. Similarly, LN contains several functional groups that help to strongly adsorb Pb ions which reduce the Pb bioavailability in the soil [15,16]. It has been reported that the sum of released cations like K, Na, Ca and Mg from amendments is almost equal to the quantity of adsorbed metal ions, explaining the primary function of cation exchange in Pb sorption by BH [31]. Likewise, an improvement in the Fe concentrations of rice grain was reported after the application of iron compounds [29].In our experiment, the highest grain Mn and Zn concentrations were found with BR 2% and LN 2% treatments, compared to control. The higher concentrations of Fe in pea grain could be attributed to the presence of Fe in the FeHP amendment. It has been reported that amending metal-polluted soil with BR significantly improved the concentrations of Mn and Zn in brinjal [13] and sunflower [28]. Likewise, the highest significant Fe concentration was observed with FeHP treatment, compared to control (Figure 2). Therefore, the reduced bioavailability of Pb in the soil improved the phyto-availability of micronutrients, especially Mn and Zn and their uptake by the plant roots due to their antagonistic behavior with Pb ions [30].
