Compound pendulum double-cavity jaw crusher

Abstract

The invention relates to a compound pendulum double-cavity jaw crusher. The compound pendulum double-cavity jaw crusher is characterized in that an upper end of a compound pendulum double-cavity jaw crusher body is provided with a slide block unit; the slide block unit is connected to a double-face movable jaw body located in the compound pendulum double-cavity jaw crusher body; two movable jaw plates are respectively fixed on two faces of the double-face movable jaw body by a movable jaw pressing plate; an upper end of the movable jaw pressing plate is provided with a material distribution plate; a lower end of the double-face movable jaw body is connected to an eccentric shaft; a motor drives the eccentric shaft to rotate; two inner sides of the compound pendulum double-cavity jaw crusher body are respectively provided with two jaw fixing frames; one end of each one of the jaw fixing frames is fixed on the compound pendulum double-cavity jaw crusher body by a long pin and the other end is fixed on the compound pendulum double-cavity jaw crusher body by a stay bolt and a compression spring; fixed jaw plates are fixed on the two jaw fixing frames by fixed jaw pressing plates; a low end of the interior of the compound pendulum double-cavity jaw crusher body is provided with bracket grooves; the bracket grooves are connected to the jaw fixing frames; and an upper part of the compound pendulum double-cavity jaw crusher body is provided with a feed inlet. The compound pendulum double-cavity jaw crusher is suitable for crushing processing of a material having high hardness and / or strong brittleness, and has high crushing production efficiency, good crushing effects and low energy consumption.

Description

technical field [0001] The invention belongs to the field of crushing equipment, and in particular relates to a compound pendulum double-cavity jaw crusher used for crushing materials with high hardness and high brittleness. Background technique [0002] Crusher is commonly used equipment in mining, metallurgy, ceramics and other industries. Common crushing of high-hardness materials in production, such as: crushing of fused magnesia chrome sand, chrome ore or corundum in the refractory industry; crushing of sintered ceramic return materials in the ceramic industry; aluminum chromium slag in ferroalloy factories The recycling treatment of peridotite iron ore, etc., all need to crush the material. However, due to the high hardness of the raw materials, the Mohs hardness is between 7-9, so there are generally problems of high crushing difficulty and low efficiency. In addition, the common jaw crusher currently used has the disadvantages of low crushing efficiency, high power...

AI Technical Summary

Problems solved by technology

However, due to the high hardness of raw materials, the Mohs hardness is between 7-9, so there are generally problems of difficult crushing and low efficiency.

In addition, the common jaw crusher currently used has the disadvantages of low crushing efficiency, high power consumption, and low output because the crushing of the material is broken once by the rotation of the eccentric shaft.
