Ore fine crushing is a process of crushing ore blocks with a feeding particle size of 50–150 mm to 5–25 mm, and the maximum crushing ratio of fine crushing is about five. The main equipment suitable for fine crushing operations includes a fine crushing jaw crusher, short head cone crusher, high-pressure roller mill, etc. Ore superfine crushing.

Run-of-mine ore is usually too large to be useful for construction or metallurgy. Large particles must be reduced to specific sizes to either comply with aggregate sizing regulations, or facilitate mineral liberation; therefore, in the aggregates and mineral processing industries, run-of-mine ore is broken in crushing circuits by cone …

The process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into …
