Overgrinding In Grinding Circuits

Overgrinding In Grinding Circuits

In grinding circuits, energy is wasted when particles are ground to a size finer than is necessary. such overgrinding can be caused when particles are retained in the circuit for too long and continue to be ground even after they have reached the target product size of the circuit. there are two factors that contribute heavily to overgrinding: (1) inefficient classification returning a large fraction of the finest particles to the circuit;.

The benchmark circuit varies with plant capacity and ore competency: • single stage crush/single stage sag mills and two stage crush/ball mill circuits are typically selected for low throughput plants ( 50 t/h) where personnel costs are a large component of costs. • sab circuits.

Grinding Circuit

Grinding Circuit

The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. a flow sheet of a typical iron ore crushing and grinding circuit is shown in figure 1.2.2 (based on ref. [4]). this type of flow sheet is usually followed when the crude ore contains below 30%.
