What is screening screening is the separation of material into 2 - 6 different sized products.The material is separated by passing it through a vibrating screen box which has a number of different sized screens, or meshes, which the material falls through like a seive.
We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;Ball mill, flotation machine, concentrator and other beneficiation equipment; Powder Grinding Plant, rotary dryer, briquette machine, mining, metallurgy and other related equipment.
Following the primary-crushing stage, screens with two or three decks and different opening sizes separate the aggregate material into different size categories with conveyors transporting the sized material for further crushing or stockpiling as a saleable product.Usually this screening is accomplished through dry screens.
We have rock crushing theory,the energy consumption model of rock crushing is developed based on fractal and fracture mechanics theory.A quantitative relationship between the energy consumption and average size of rock fragments are obtained.A calculation method for determining the rock fracture surface energy is introduced according to the shpb tests.
