Jaw crusher provided with buffering material feeding hopper

Abstract

The invention discloses a jaw crusher with a buffer feeding hopper, which comprises a jaw crusher and a buffer feeding hopper. The jaw crusher is provided with a No. 1 movable jaw and a No. The jaw and the No. 2 movable jaw are driven by the driving mechanism to swing in opposite directions. The buffer feeding hopper is connected above the jaw crusher through a flange. The buffer feeding hopper includes a hopper body, a buffer assembly and a wear-resistant liner. The buffer assembly has two groups. , the first group is arranged on the inner plate of the hopper body, the second group is arranged under the inner plate of the first group, and the wear-resistant liner is arranged on the inner plates on both sides of the hopper body. The two movable jaws of the present invention extrude the material bidirectionally, and the extrusion force on the material is greater, which makes the material easier to break, and through the blocking of two groups of buffer components, it plays the role of buffering and uniform feeding. The movable jaw plate in the machine plays a very good protective role, reducing the impact and wear of ore on it and prolonging its service life.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a jaw crusher with a buffer feeding hopper. Background technique [0002] Jaw crusher is commonly known as jaw crusher, also known as tiger mouth. The crushing cavity is composed of two jaw plates, the movable jaw and the static jaw, which simulate the movement of the two jaws of animals to complete the material crushing operation. It is widely used in the crushing of various ores and bulk materials in mining smelting, building materials, roads, railways, water conservancy and chemical industries. [0003] Jaw crusher is composed of jaw crusher, drive motor, movable jaw, static jaw and so on. During the working process of the jaw crusher, the motor drives the pulley, and the pulley drives the eccentric shaft, and the eccentric shaft can move the movable jaw during the rotation process. In this way, the distance between the movable jaw and the static jaw will sometimes...

AI Technical Summary

Problems solved by technology

In the feeding process, due to the impact of the ore from a certain height, the wear of the jaw plate of the jaw crusher is aggravated, mainly the movable jaw plate; and due to the uneven feeding, the partial wear of the movable jaw plate will be serious, resulting in the entire movable jaw. The service life of the board is reduced, which increases the maintenance cost of the equipment
