FLS Double Roll Crushers are capable of impressively high throughput rates – up to 14,000 tph – thanks to the customised tooth and liner design and optimised installed power and drive set-up, while our Eccentric Roll Crushers offers up to 10% more throughput compared to industrial benchmarks, with up to 40% energy cost savings.
This assumes that a crusher would provide this energy. However, in this situation the ball mill has to supply this energy and it has a different (higher) work index than the crusher (i.e., the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from Eq.
Currently, in the primary crushing stage, commonly used crushers include jaw crushers and gyratory crushers. Recently, FL (2022) has introduced an eccentric roll crusher, which has gained favor in the crushing industry due to its high efficiency and energy-saving advantages. They are widely used for primary crushing of ores such as iron and copper.
The rolls provide toothed patterns suited to the feed material. Single Roll Crushers generally handle larger feed sizes at higher reduction ratios in higher capacities. These machines are also great as lump breakers. Double Roll Crushers. Double roll crushers reduce primarily through compression, although toothed rolls provide some shear.
