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.copper concentrate machine 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. 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. The stone crusher set, which includes vsi5x stone crusher, vsi series stone crusher, jaw crusher, impact crusher and mobile crusher, is manufactured by Heavy Industry. Sand and gravel can be produced by our river sand mining equipment. Fine aggregate can be manufactured by crushing and processing hard rocks such as limestone and sandstone to produce fine grained (sand-sized) material.The degree to which such crushed rock sand can replace natural sand varies with rock type, the degree of quarry processing used and end-use.
