Problems solved by technology

[0005] (1), need to use crusher, conveyor and vibrating screen three equipment, high cost;
[0006] (2) The floor area is very large. Because the conveyor has a conveying upper limit angle (generally <18°, if the angle is too large, the material will be dropped), and the crushing and screening equipment and its base have a certain height, so every The average length of the conveyor is 20-35m
The entire crushing production line is very large, and naturally occupies a large area;
[0007] (3) The equipment must be installed and operated at a distance, which is not convenient for unified use and management;
[0008] (4) The conveyor must be used to complete the logistics transportation between the equipment, which increases the input cost and operating power consumption of the conveying equipment

Abstract

The invention discloses a crushing and screening machine which comprises a crushing mechanism, a base, a vibration box body and a rack, wherein the crushing mechanism, the base and the vibration box body are combined into a whole body from top to bottom; the base is arranged on the rack via an elastic support mechanism; a plurality of screens are arranged in the vibration box body. The crushing and screening machine disclosed by the invention combines an eccentric shaft or a coaxial shaft in crusher equipment and an excitation shaft in vibrating screen equipment into a whole body to realize the integration of crushing and screening, and completely avoids the huge energy consumption caused by transportation and screening, and completes the screening operation through the vibration generated by the crushing movement of a crusher to convert the disadvantages into the advantages.

Description

technical field [0001] The invention relates to the technical field of mining machinery, and more specifically relates to a screen breaking machine. Background technique [0002] Crushing and screening are two of the most basic and common operations in the field of mining machinery. [0003] Crushing and screening have a common structural feature, that is, they both contain an eccentrically arranged main shaft. The main shaft is called "eccentric shaft" in the crushing structure, and "exciting shaft" in the screening structure. The function of the eccentric shaft is to make the crusher produce a crushing stroke, so as to effectively crush; the function of the exciting shaft is to make the vibrating screen generate an exciting force, so as to effectively screen. The functions of the two are different, but their structures have the same thing, that is, both have "eccentric structure". [0004] In the prior art, the crushing operation and the screening operation are complete...
