Because the bar feeder uses a pair of vibrating motors with identical performance parameters as excitation sources, when the two vibrating motors are operated in opposite directions at the same angular speed, the inertia force generated by the eccentric blocks of the two vibrating motors is repeatedly overlapped or offset in a specific phase, so that huge synthetic excitation power is generated, the machine body of the bar feeder forms forced vibrating power on the supporting spring to drive the material to slide and throw on the trough, the material is continuously moved forwards and the earth fine materials on the stone are removed, and the aim of relatively clean feeding is achieved. Meanwhile, when materials pass through the screen bars on the groove body, smaller materials can fall through the gaps of the screen bars, the screening effect can be achieved without the crushing procedure of the next channel, and tiny stones are directly conveyed to the vibrating screen through the conveying belt.

3. The jaw crusher crushes relatively clean stone materials output from the bar feeder under the control of the PLC controller, so that the crushed stone materials are continuously conveyed to the primary vibrating screen through the conveying belt to be vibrated and screened.

4.

6. The feeding amount of the feeding machine in the middle stock ground is adjusted according to the preset material level in the stock bin of the PLC controller, sand and stone output by the feeding machine are conveyed to the feeding machine through the conveying belt, the feeding machine uniformly and continuously feeds block-shaped and granular materials from the stock bin to the single-cylinder hydraulic cone sand making machine, the single-cylinder hydraulic cone sand making machine rolls and presses machine-made sand, and the produced machine-made sand is screened through the conveying belt to the vibrating screen.

7. The single-cylinder hydraulic cone sand making machine is a prior patent of the applicant, stones from a feeder are crushed into sand, a vibrating screen is conveyed by a conveying belt, screening of four different specifications is completed by vibrating screening, massive stones are conveyed to a cone crusher by the conveying belt to be crushed by secondary crushing, and 0-5mm machine-made sand is directly conveyed to a sand scooping machine by the conveying belt to be carried out at a subsequent position; 5-16mm machine-made sand is conveyed to a finished product pile, 16-31.5mm machine-made sand is conveyed to the finished product pile, and stones with the diameters of more than 31.5mm are recycled to a conical sand making machine through a recycling conveyor belt to carry out secondary rolling sand making.

8. Since the stone sources are various, the stone may not be mixed with impurities such as iron blocks. In order to ensure the normal operation of the system, the system is provided with a current overcurrent device, an overload protection device, a rapid hydraulic protection device of a single-cylinder hydraulic cone crusher or a sand making machine and a shutdown protection device.
