Hardness: Hard materials like granite and basalt are suitable for jaw crushers or gyratory crushers, while softer materials like limestone and coal can opt for impact crushers or hammer crushers. Abrasiveness: Materials with high abrasiveness like iron ore require crushers with good wear resistance, such as cone crushers.
The grid spacing of the lower grid is generally 25- 30 mm. Higher moisture content of the crusher feed requires larger spacings up to 60 mm. Depending on the requirements, a spacing of 200 mm can also be applied. ... moisture content less than 12%, with compressive strength less than 120MPA, such as limestone, oil shale, slag, coal and so …
The roll crusher is the workhorse of coal size reduction to shear and/or compress the material. From: Encyclopedia of Energy, 2004. About this page. ... The maximum particle size of a limestone sample received from a cone crusher was 2.5 cm. It was required to further crush it down to 0.5 cm in a roll crusher with smooth rolls. The friction ...
When larger feed sizes require up to a 6:1 ratio of reduction to achieve the final product, a Triple Roll Crusher should be chosen due to the inherent design, which allows the larger feed sizes to be readily grabbed in the large throat opening between the top (primary) roll and crushing plate.
1980 - Gearing for the gyratory crushers changed from straight bevel to skewed or spiral bevel and castings to forgings which are carburised and case hardened. These changes allowed the crusher manufacturer to increase the power to the crusher without substantially increasing the space required.
