Aggregate used in railways, roads, buildings industry, Human civilization developing is related with aggregate industry. Your choice will directly affect productivity, cost per ton and the profitability of your whole operation. It will depend on many factors including the type of rock, characteristics of your site, and the precise quarrying application.Selecting the right machines for your quarry is a vital decision.
Mining process of iron ore is a complex process from ore mine to ore industrial production, which including milling (crushing and grinding), washing, filtration, sorting, sizing, gravity concentration, magnetic separation, flotation separation and pelletization. It aims to remove the unwanted impurity materials or gangues, improve the iron ore grade and refine the concentrate for final applications.

Anvil type impact crushers utilize a hard target such as manganese steel as the target area. The autogenous variety uses a bed of the same material that is being broken or crushed as the target area so that the rock which is accelerated impacts against other rock of the same type.Impact crushers operate on the principle of accelerating the rock to a high speed and causing it to impact against a target which will cause the rock to fracture. There are essentially two types of impact crushers: autogenous impact crushers and anvil impact crushers.
2%1−n−Γ(α2−n+1α2)x2P=63.In the case of fluidization state re-specification, it is usually necessary to reduce the size of feeding coal particles to achieve steady operation under a lower bed pressure drop.2%1−n). For crushers, if the size distribution of inlet particles is fixed, the comminution energy change with the different sizes of products can be calculated as follows :Δe=Cn−1(∑j=1Np1(j)xpj1−n−∑i=1Np2(i)xpi1−n)=Cn−1(Γ(α1−n+1α1)x1P=63.
Afteranalysing the resultsobtained by various techniques critically, thebulkoil flotation of the rougher cellconcentrate,was found to be the most suitable technique. The columnflotation trials studying process variables such as pulp density,depressant concentration and airflow rates, yielded the best grade of column concentrate containing64% F.The low grade graphite ore sample from Multai area, Betul District, M., with an overall graphite recovery of 74.C.C.7% F.5% F. The best grade containing 72. The bestgradeconcentrate containing 60. witha recoveryof90.C. was obtained by bulk oilflotationof therougher concentrate containing 53. Conventionalmechanical cell flotation trials were conducted and various process variables such asfroth erlcollector/depressantconcentrations, pH of the pulp etc.P analysed 10% graphite andwasfound to be crvptocrystalline in nature and intimately associated with silicate gangue.6%.88%.Further improvement in thegrade was possible by only resorting to the bulk oil flotation of the finely ground sample (less than 37 microns).C., were optimised.12%. was obtainedaftercleaning the rougher concentratetwice, with arecovery of 72.1% F.
