Problems solved by technology

[0004] The purpose of the present invention is to provide a crushing and screening device to solve the problem that the existing ore crushing device for mining in the above-mentioned background technology needs to go through the process of repeated crushing when it needs to meet the crushing requirements. For thicker ore, sometimes It will damage the crushing tool in the device, and it cannot be screened after crushing. Screening will increase manpower consumption, which greatly reduces the problem of work efficiency.

Abstract

The invention relates to a crushing and screening device. The crushing and screening device comprises supporting posts and a crushing tank, wherein hydraulic pumps are arranged on the upper ends of the supporting posts; hydraulic rods are arranged on the upper ends of the hydraulic pumps; a pushing plate is welded on the upper ends of the hydraulic rods; the crushing tank and the supporting postsare in welding arrangement; the crushing tank comprises a top cover, a first crushing chamber and a second crushing chamber from top to bottom; the first crushing chamber is formed by a plurality of crushing posts and a first filter plate; the second crushing chamber is formed by a plurality of crushing cutters, a second filter plate and a material outlet. Through the combination of twice crushingand twice filtering and screening, the crushing and screening device is not only capable of increasing the crushing efficiency, but also is beneficial for saving the labor for follow-up screening.

Description

technical field [0001] The invention relates to the technical field of crushing and screening devices, in particular to a crushing and screening device. Background technique [0002] At present, in the process of mining stone, people have higher and higher requirements on the quality of stone. In order to ensure that the stones mined in the mine are broken into crushed stones of suitable size, the existing crushing methods include manual hammer crushing and machine crushing. The method, manual hammering and crushing requires a lot of manpower and material resources, but now the machine crushing method is basically used. [0003] When the existing ore crushing device used in mine development needs to meet the crushing requirements, it needs to go through a repeated crushing process. For ore with a large thickness, sometimes the crushing tool in the device will be damaged, and the crushed material cannot be screened after crushing. Cause subsequent screening to consume manpow...
