Crushing in Mineral Processing
Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.
Solved 5.1 A primary gyratory crusher was required to crush …
5.1 A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the Run-of-Mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer's data indicated that the nearest size of gyratory crusher would be 1370 mm x 1880 mm with a cone angle of 18°.
Ore Crushing
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. Ore medium crushing is a process of crushing ore blocks with a feeding particle size of 125–400 mm to 50–100 mm.
Types of Crushers: Choosing the Right One for Each Stage
The maximum feed size for a jaw crusher can reach 1,200 mm. They perform better than gyratory crushers on high-humidity, high-viscosity materials like clay, but often produce output with poorer particle shapes, such as flat, sharp, or triangular particles. Gyratory Crusher
