Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Crusher Plant LayoutCrushingScreeningMost crushing plants are now designed on the lines shown in Fig. 1, which is a diagrammatic view of a two-stage arrangement.The ore from the mine is dumped in the coarse ore bin, from which an automatic feeder delivers it over a grizzly to the primary breaker, the latter being of the jaw type in the case of a small plant and of the gyratory type in the case of a large one. The reduction ratio—that is, the ratio between the “ inch size ” of the largest lump entering the machine and that of the...

THESIS FOR THE DEGREE OF L ENGINEERING IN

Crushing plants are a vital part in the production of aggregates and metals. Plants are traditionally simulated with a steady-state simulation. With steady-state simulation the plant is simulated until equilibrium is achieved. However, crushing is a continuous process and as such it is subjected to variations and changes in performance depending on the dynamics of the system. A different ...

Mineral processing - Wikipedia

The primarily used equipment in crushing are-jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy intensive.
