· Ore coarse crushing is a process of crushing ore blocks with a feeding particle size of 500–1500 mm to 125–400 mm. The maximum crushing ratio of coarse crushing is about three. The main force in the coarse crushing of ore is crushing. Typical coarse crushing equipment includes jaw crusher, gyratory crusher, and roller-tooth crusher.

Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
