Iron ore Combinatorial optimization Simheuristic Simulation 1. Introduction Crushing circuits decrease the size of ore extracted from a mine until it is suitable for the next mineral processing steps. The sequential primary, secondary, tertiary, and quaternary crushing stages compose a crushing circuit.

Introduction Hematite and magnetite are the most prominent iron ores. Most of the highgrade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.

ABC closed circuit, AutogenousBallMillCrusher. Another similar technique is the ABC open circuit where the crusher product feeds the ball mill rather than the autogenous mill. Crusher product is typical feed to a ball mill using large diameter balls but not much grinding of 2025 mm ore can be accomplished in an autogenous mill.

The high speed rotor throws the ore to the outside of the crusher. Crushing results from interparlicle collisions and from ore striking the hammer or material bed that forms at the periphery of the crushing chamber. These crushers can be supplied with mechanical wear components and liners or for autogenous operations. Roll Crushers

General point about the graphs: I would use Ore Crusher 1 rather than Burner Ore Crusher. These are super easy to research and are a cheap upgrade. Simplifying the graphs (even a small bit) is a good thing. Power Generation (coal processing) Charcoal. Not coal.
