Further, synchronous machine is provided with two, guarantees that equipment shell vibrates steadily and the cadence is unanimous.

Further, the spring group can periodically absorb and release energy generated by the vibration of the equipment shell.

Furthermore, the screen cloth total is twice, and parallel arrangement is in broken fluted roller below from top to bottom, and the aperture of twice screen cloth is big-end-up's arrangement.

The utility model has the advantages that:

1. the functions of the traditional coarse, medium and fine crushers and the functions of the vibrating screen are integrated, so that the use of auxiliary equipment such as a belt conveyor, a feeding chute and the like is greatly reduced, the land use area is greatly reduced, the cost is saved, and the one-time investment cost is reduced;

2. the equipment number is greatly reduced, and the installation cost and the maintenance cost are reduced;

3. the number of intermediate links is reduced, the number of fault points is small, and the shutdown maintenance time is shortened;

4. ore is conveyed back and forth without a belt, so that the transportation energy consumption is reduced, and the production efficiency is improved;

5. the ore is crushed by using a high-frequency striking mode, so that the crushing effect is stronger, and the crushing efficiency is higher;

6. the flange is directly connected with the feeding chute, so that the sealing effect is good, and the environment is protected.
