In a stone crushing plant, the crushing process is very important. The raw materials pass through the raw material bin and are evenly fed into the hammer crusher for preliminary crushing under the action of the vibrating feeder. Then they are transported by the belt conveyor to the double-rotor sand making machine. , carry out fine crushing + shaping processing, and then screen by vibrating screen. Aggregates that meet the finished product specifications directly enter the finished product area, and stones larger than the finished product specifications are returned to crush again. Finally, different specifications of crushed stone and machine-made sand can be obtained, including: 0-5-10-20-30mm.
