Reciprocating jaw type crusher for sintered bricks

Abstract

The invention relates to a crusher of sintered bricks in building waste. A reciprocating jaw type crusher for sintered bricks comprises a crushing bin body I, a crushing bin body II, crushing devices and reciprocating power mechanisms, wherein the crushing bin body I and the crushing bin body II are longitudinally laminated and arranged; the crushing devices are arranged in each crushing bin body in a matched mode; the reciprocating power mechanisms drive the crushing devices; the crushing devices comprise static jaw plates, movable jaws and movable jaw plates, wherein the static jaw plates are fixedly arranged on one side surfaces in the crushing bin bodies; the movable jaws correspond to the static jaw plates and are matched with and in sliding fit with the crushing bin bodies; the movable jaw plates are fixed on the movable jaws; the driving ends of the reciprocating power mechanisms are in connection driving with the movable jaws. The crusher is reasonable in structure design, is high in sintered brick utilization ratio, can control the crushing and discharge particle diameter easily, can obviously reduce the content of needle-shaped or flaky aggregate after discharging, so that the regenerated aggregate can be well adaptive to regenerated concrete preparation and other fields of engineering construction.

Description

technical field [0001] The invention relates to a device for crushing sintered bricks in construction waste, in particular to a reciprocating jaw crusher for sintered bricks. Background technique [0002] The jaw crusher is a crushing chamber composed of two jaw plates, the movable jaw and the static jaw. It simulates the movement of the two jaws of animals to complete the material crushing operation. It is widely used in mine smelting, building materials, roads, railways, water conservancy and chemical industry. Crushing of various ores and bulk materials in the industry. The movable jaw of the existing jaw crusher adopts a motor, and the eccentric wheel is driven by the belt to complete the crushing action between the movable jaw and the static jaw. The mechanical safety performance is low, and the crushing effect is not ideal. Broken aggregates will be splashed out, and a large amount of dust will be generated during the crushing process, which will cause serious environ...

AI Technical Summary

Problems solved by technology

The movable jaw of the existing jaw crusher adopts a motor, and the eccentric wheel is driven by the belt to complete the crushing action between the movable jaw and the static jaw. The mechanical safety performance is low, and the crushing effect is not ideal. Broken aggregates will be splashed out, and a large amount of dust will be generated during the crushing process, which will cause serious environmental pollution and cause problems such as low utilization rate of fired bricks.

[0003] In the existing crushing jaw structure design, due to its relatively fixed structure, it is impossible to carry out targeted design according to the characteristics of the crushed aggregate. Therefore, a large number of needle-like and flake-like particles are likely to be produced during the crushing process of sintered bricks.

Sintered brick aggregates with a large number of needle-like and flake-like particles are used as recycled aggregates to configure concrete. The basic mechanical properties such as compression resistance and splitting of recycled brick aggregate concrete are poor, which restricts the use of recycled brick aggregate concrete. application

If the fired brick aggregate with a large number of needle-like and flake-like particles is processed twice, it will increase the production cost, which is not conducive to the resource utilization of fired bricks
