Basic Flow:
1. Stones are evenly sent into jaw crusher by vibrating feeder, for coarse crushing.
2. The crushed materials are sent into sand making machine by traveling apron, for fine crushing.
3. Then the materials are transmitted to the vibrating screen and classified according to different sizes.
4. The qualified stones are washed by sand washing machine and sent out by belt conveyor. Those unqualified stones are sent back to the sand making machine and crushed again.
5. If users adopt dry production technology, the sand and gravel production line should be equipped with separator (for separating coarse powder and fine powder) and dust removal plant.

Features of Sand and Gravel Production Line:
1. This sand and gravel production line has the characteristics of high automation, low operating cost, high crushing rate, high productivity, and little pollution, etc. It is energy saving and is convenient to maintain.
2. Sand made by our sand and gravel production line is of equal size, good shape and reasonable distribution, complying with national building sand standard.
3. Except the startup, shutdown and routing maintenance, the crushing equipment can perform its duties automatically.
4. Due to reasonable matching of crushing machines and compact spatial arrangement, our crushing and screening plant has the features of small floor space and high economic efficiency. The crushed stones are of high quality, and the output rate of stone powder is low.
5. Meanwhile, our sand and gravel production line is equipped with electronic control system which ensures smooth discharging, reliable performance, high efficiency and energy conservation.
