Abstract

The invention relates to a grain crushing and screening device which comprises a machine frame, wherein the interior of the machine frame is provided with a crushing cavity, a screening cavity, a collecting cavity and a recovering delivery pipe; the crushing cavity, the screening cavity and the collecting cavity are sequentially arranged from top to bottom; and the recovering delivery pipe is respectively connected with the screening cavity and the crushing cavity. The grain crushing and screening device integrates the crushing and screening, greatly saves the occupation space and has simple structure. The grain crushing and screening device is provided with the recovering delivery pipe, can send back grain particles with particles being not in line with the size requirement again, and realizes the multi-stage crushing, good crushing effect and high working efficiency.

Description

Technical field [0001] The invention relates to a crushing device, in particular to a grain crushing and screening device. Background technique [0002] In the prior art, grain pulverization is generally completed by a combination of multiple mechanical equipment such as pulverizers, screening machines, recovery devices, etc. The disadvantage of this pulverization method is that it uses a lot of equipment, takes up a large space, and has a long battle line. Summary of the invention [0003] The purpose of the present invention is to provide a grain crushing and screening device, which occupies a small space, has a simple structure and high working efficiency. [0004] In order to achieve the above objective, the technical solution of the present invention is: a grain crushing and screening device, including a frame, characterized in that a crushing cavity, a screening cavity, a collection cavity and a recovery conveying pipe are arranged in the frame. , The screening cavity and the...
