In the secondary crushing, we choose the PF1214 impact crusher whose capacity is 80-160 tph. During the stone crushing plant, the impact crusher is suitable for medium and fine crushing the rocks. It is a new type highly efficient crushing machine with the advantages of small size, simple structure, high crushing ratio, low energy consumption,alluvial gold mining equipment high production capacity, even product granularity and selective rock crushing, so that it is a promising crushing equipment. For screening materials for different sizes, vibrating screen is playing its role. After separating, the aggragates that can meet your requirements will be separated out as final products, while the other aggragates will be returned to cone crusher or vsi crusher.stone quarry machinery Size of final products can be combined and graded according to your specific requirement. Feldspar grinding is the required process when the size is below 5-20 mm. Mining in Australia is a significant primary industry and contributes to the Australian economy. The mineral resources are the important components in the economy development of Australia. The minerals are usually used to export.silica crushing plant According to the 2002 estimate, Australia occupies 13Gt proven iron ore reserve and it can be mined for 70 years.Australia ranks the fourth position in the world. It is also one of the biggest iron ore production countries. The iron ore year‘s production is about 17% of the whole world and Australia is only behind China and Brazil. As we can see, the iron ore mining equipment in Australia plays an important role in the economy development. Extracted from the mineral ore, the raw materials are sent into jaw crusher for the first crushing stage through vibrating feeder. In jaw crusher the materials are crushed into coarse ones which are taken into cone crusher or impact crusher for the further crushing in the secondary section. To get the fixed materials size, these materials should be sent into the grinding mill to be grinded. In this equipment, the desired size will be got.raymond roller mill While next is the magnetic separation. Depending on the different properties of the materials, the magnetic minerals will be separated from others. In the flotation process, the separation process will be achieved by using chemical reagents that preferentially react with the desired mineral.
