The hammer crusher with feed rollers (F.L.S) is a special form of construction to avoid complicated, multi-stage crushing, a hammer has been developed, which does not require preceding primary crushing. This crusher reduces rock lumps from 2 m size down 25 mm. The crusher uses a single hammer rotor with peripheral speed of about 40 meters per ...

An apron feeder is a mechanical feed conveyor used to extract raw material typically from dump hoppers, bins and stockpiles. Apron feeders are used to extract or feed materials at a short distance with a controlled rate of speed. Typical applications include primary hopper recovery, stockpile reclaim, crusher feed and reclaim, ship and rail-car ...

A primary crusher breaks up large pieces of rock or concrete from the blasting or excavation process and turns them into smaller, more manageable chunks. This is the first step in the crushing process. The smaller pieces can then either be pre-screened or fed directly into a secondary impact or cone crusher.

The frequent best practice for managing large low-grade run-of-mine (ROM) stockpiles is to average the entire stockpile to only one grade. Modern ore control and mineral processing procedures need better precision. Low-precision models hinder the ability to create a digital mine-to-mill model and optimize the holistic mining process. …
