The findings of the study have shown that it is difficult to quantify the total ore loss due to the time lag between breaking of the rock and processing of the ore to the final product when estimating the mine process inventory. The inability to minimize ore loss can thus impact negatively on mine output through the loss of revenue.
The VSI crusher is often used in the production of sand for concrete production. The desired product is often a 0–4 mm fraction or a 0–8 fraction. Sometimes there is a need to produce a 0–2 mm and a 2–4 mm fraction, which is achieved with a screen. In Fig. 7, a schematic description of a pilot plant is presented. This pilot plant is ...
