The highest compression strength of the crushed materials is 320 MPa. The performance characteristics are large crushing ratio, uniform product granularity, simple structure, reliable performance, simple and convenient maintenance and low operation cost. The double-roller crusher enables crushed materials to fall between the two rollers through the feeding port, extrusion crushing is conducted, and finished materials naturally fall down. When the roller crusher is over-hard or non-crushable objects, the roller of the roller crusher can automatically retreat under the action of a hydraulic cylinder or a spring, so that the roller gap is increased, and the over-hard or non-crushable objects fall down, thereby protecting the machine from being damaged. The two rollers rotating in opposite directions have a certain gap, and the maximum discharge particle size of the product can be controlled by changing the gap.
The design objective of the secondary screening device 4 in the present system is described below in connection with figures 11 and 12:
because the conventional screening device vibrates vertically, as shown in fig. 8, G represents the gravity of the vibrating object and the device can understand G as the gravity of the upper housing, and it is assumed that the upper housing vibrates vertically, and F represents the upward lifting force; when F is larger than G, the requirement of lifting and vibrating the vibrating object can be met;
the vibration mode adopted by the device is oblique sliding, as shown in fig. 9, wherein F1 and F2 respectively indicate that F is the decomposition acting force in two axial directions because the friction force between the roller 404 and the guide rail 403 is small and can be ignored, specifically, F1 is the pulling force along the guide rail 403, and F2 is the supporting force of the guide rail 403;
it can be seen that the magnitude of the F1 force is significantly less than F, so the device can provide power savings, and in particular, reduce the load on the drive 405; if the upper shell is simply slid back and forth along the horizontal direction, although F1 is smaller and more labor-saving, the upper shell lacks the process of up-and-down movement, and the vibrating screening effect is poor;
therefore, the device can simultaneously vibrate up and down and left and right, and the screening effect is good.
The workflow of the system is introduced as follows:
the first conveying device 501 is used for conveying stones to be crushed, the stones have large size difference, large stones contain small broken stones, the large stones pass through the diversion screening plate 103 of the primary screening device 1 and then enter the primary crusher 2 from the primary screening discharge port 101 to be crushed, and the small broken stones pass through the primary screening holes 105 to the second conveying device 502;
crushed stones behind the primary crusher 2 and crushed stones at the primary screening discharge opening 102 enter the secondary crusher 3 through the second conveying device 502 for crushing; the secondary crusher 3 further crushes the crushed stones to form gravel aggregates, and the gravel aggregates are conveyed to the secondary screening device 4 by the third conveying device 503 for screening treatment;
the secondary screening device 4 discharges the sand aggregate with qualified size from the secondary screening discharge port 402, and transports the sand aggregate to a factory warehouse through a fifth transport device 505, and the unqualified sand aggregate is transported to the secondary crusher 3 through a fourth transport device 504 to be crushed again.
