Crusher

Crushed ore feeds this bin continuously and the bin overflows to a small conveyor feeding a dead stockpile. In the event of a primary crusher failure, the crusher loader is used to reclaim the stockpile via the surge bin, which doubles as an emergency hopper. • For coarse ore, the next alternative is a coarse ore stockpile.

Crushing Plant Design and Layout Considerations

2016-2-24 · Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine''s trucks, then operators must slowly meter the ore into the receiving hopper.

Crushers

The main purpose of a primary crusher is to reduce the material to a size that allows its transportation on a conveyor belt. In most crushing installations a jaw crusher takes care of primary crushing. Plants with very high capacities that are common in mining and less popular in aggregates production, normally use a primary gyratory crusher.

Innovation Doesn''t Always Look Innovative: A Case Study …

2019-5-16 · Take, for example, the rock crushing system inherent to the mining process. A known issue for some gyratory crushers is the tendency for the inlet pit to be overwhelmed by material. When too many rocks fill the pit before they can be fed passively into the crusher, the rocks interlock and create blockages.

Mine Gold Ore Stockpile Blending

Whereas this design suits the mining process and is operationally simple, there can be little confidence in the grade of the ore that is fed to the crusher. This makes shortterm grade control difficult and reconciliation back to the mine face imprecise. Welldesigned and operated precrusher stockpiles can overcome these deficiencies.
