Gangue is a by-product of coal mining and washing, and its efficient crushing is a key link in resource utilization. The medium and large-scale gangue crushing production line with an output of 300 tons per hour needs to select the appropriate equipment according to the material hardness, particle size requirements and production environment. The following are several mainstream crusher models:

‌Jaw crusher‌

Adopting the principle of extrusion crushing, the crushing chamber formed by the movable jaw and the fixed jaw can handle large gangue with a particle size of more than 1 meter, and the crushing ratio is 6-8 times. The heavy cast steel body and wear-resistant jaw plate design make it suitable for the primary crushing stage, especially for high-hardness gangue. 300 tons per hour requires PE-1200×1500 or larger specifications, and the overall efficiency can be improved with the pre-screening system.
