crushing equipment flow chart for gold mining in pdf

Mechanised crushers in gold mining typically operate by pinching a rock between two metal plates (jaw, gyratory, or cone) or through the impact of a metal surface on a rock (hammer mills and stamp mills). The following are common types of mechanised crushers used in gold mining: Jaw crusher - Jaw crushers are common in artisanal gold mines.

The choice of crusher depends on the type and amount of material to be crushed. Gyratory and jaw crushers represent the bulk of primary crushers used at mining operations today, although some operations use roll impact crushers, low-speed roll sizers and feeder breakers.

In the context of artisanal or small-scale mining, manual crushing, grinding, and sieving methods are employed for producing gold ore. If the rocks are large to begin with, a common method for sizing them down to fit into a stamp mill or ball mill for grinding is crushing.

Electronic control of crusher discharge opening and feed rate. With adjustment of a crusher’s discharge opening, as the production continues through an on-line coarse size analysis of the crushed product (digital image analyses). Dance, A. 2001)

The user will have to choose between the two main types of crushers for fi ne crushing and cubicising – i.e., cone and impact crushers. The decisive factors for selection of the most ap-propriate equipment are the abrasiveness and crushability of the material, as well as the de-sired gradation curve. tors are.

In fine crushing applications there are more possibilities for crusher selection depending on sivenss, for example Line, there are rock-on-anvil VSI crusher and HSI crusher that would suit to the job. For good shape requirement, rock-on-rock VSI crusher is performing well in all kinds of applications regardless of the high abrasivenss.
