Ore Preparation Processes Crushing

crushing in mineral processing - 911 metallurgist,the crusher throw is defined as the distance in the direction of compression the moving crushing surfaces/plates travel from oss to css. throw = oss – css. oss and css will define a crusher’s performance. the throw of the crusher is the distance that moving jaw moves in going from oss to css. the capacity is a function of size and oss..iron ore processing,crushing,grinding plant machine desgin,after crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore. the beneficiation process should be as efficient and simple as possible, such as the development of energy-saving equipment, and the best possible results with the most suitable process..

    Crushing, Grinding And Concentration Of The Ore

    (1) crushing and grinding of the ore. the ores occur in nature as huge lumps. they are broken to small pieces with the help of crushers or grinders. these pieces are then reduced to fine powder with the help of a ball mill or stamp mill. this process is called pulverisation. (2)
