The Dressing Is a Variety of Useful Mineral Raw Materials in the Left

The dressing is a variety of useful mineral raw materials in the left, used sag mill for sale price next we will learn more about mineral processing before the election, mineral raw material preparation which have operations. Before the election, mineral raw material preparation which comprises a crushing (including the crushing machine and grinding, screening and classification), sometimes including ore washing.

1, the size of the crushing process mining is 500 ~ 1500mm ore fragmentation to particle size 5 ~ 25mm. Methods are crushed, breaking it, according to the coarse crushing, fine crushing, paragraph three.

2, grinding in grinding and impact. The crushing grinding to particle size 10 ～ 300 μ m size. Grinding granularity is determined according to the size of disseminated in the ore useful minerals and the identification method. Grinding equipment commonly used are: basalt crusher, ball mill, mill and semi autogenous grinding etc.. Grinding operations of high energy consumption, usually accounts for about half of total energy consumption of mineral processing

3, screening and classification according to the screen mesh size materials can be divided into different levels of granularity call screening, commonly used in the treatment of coarse grain materials. According to the particle in the medium (usually water) sedimentation velocity is different, the material is divided into different drop level, called for grading, the material with smaller granularity. Screening and classification is in the process of crushing into suitable size material, or the material is divided into different levels of granularity were selected.

4, washing to avoid containing mud mud in mineral raw materials blocking crushing,chinese complete gold plants basalt crusher, need to wash. Raw materials such as containing soluble useful or harmful ingredients, but also to wash. Can be carried out in the wash machine washing, can also be used in screening and classification equipment....
