Description

Technical Field

[0001] This application relates to the technical field of ore crushing, and more specifically, to an ore crusher. Background Art

[0002] The ore crusher performs two consecutive crushings through a double rotor, without a sieve bar device. All kinds of wet slag can be crushed, that is, it can be crushed even if it is fished out of water, and there is no phenomenon of adhesion and blockage. To control the size of the material, only the gap between the crusher hammers needs to be adjusted.

[0003] Existing ore crushers generally only perform one crushing on the ore, and the sizes of the crushed ore materials are different, which is not convenient for subsequent smelting and processing.

[0004] To solve the above problems, this application provides an ore crusher. Utility Model Content

A feeding mechanism 8 is provided on the side of the return material mechanism 6 away from the feeding cylinder 1 on the same side of the feeding cylinder 1. Support legs 7 are provided at the four corners of the bottom of the feeding cylinder 1. An outlet 9 penetrates through the outer wall of the feeding cylinder 1 near the feeding mechanism 8. An outlet groove 10 is provided at the bottom inside the feeding cylinder 1 and is in communication with the outlet 9, and the outlet groove 10 is located below the feeding plate 4.

[0024] The symmetric crushing wheels 3 are engaged with each other, and a driving motor is provided on the outer wall of the feeding cylinder 1 on the side away from the feeding mechanism 8. The output end of the motor penetrates through the top outer wall of the feeding cylinder 1 and is connected to the crushing wheel 3.
