If we have to choose between two suppliers of jaw crushers (jaw crusher), which model of crusher you would choose if you need to crush around 280 tons per hour of stone, with a stone feed (max. size 900mm), if you need 70% of the product to be less than 150 mm. Help: 70% of the products that are obtained from a shredder normally have a size less than the close side setting (CSS) given in the specifications. IS
