Big raw material will be fed into jaw crusher for primary crushing by vibrating feeder.    After primary crushing, the material will be transported to secondary crushing machine  impact crusher for further crushing.
Usually, we will equip Circular Vibrating Screen for the sandstone crushing & screening plant.    The vibrating screen is a key equipment to sieve the crushed stones into different grades.    The crushed stone that meet the demands will be transported to the stockpile, the other will be sent to secondary crusher for fineness crushing.
