Chutes SAIMH

CHUTES. Conveyor belts invariably discharge into a chute for gravitational transport of the ore onto another conveyor belt or to the next stage in the ore dressing process. The ore is discharged from the conveyor belt at considerable velocity, resulting in sever chute wear and/or belt impact.

Conveyor systems QueensMineDesignWiki

The discharge chute is most important in conveyor to conveyor transport as it reduces impact on the second conveyor system (increasing wear on the belt and reducing maintenance cost). Furthermore, poor transfer design can lead to premature belt wear, poor ore tracking, material degradation, and dust generation (SME, 2011).

to reduce the instance of dust at the mining face prior to the mining commencing. This created a large volume of free water that would precede the flow of coal through the conveyor system each time the shearer was re-started. When this free water came to an inclined conveyor the large volumes of water would create major spillage events.
