Mine rock rolling machine with adjustable discharge size

Abstract

The invention discloses a mine rock crusher with an adjustable discharging size. The mine rock crusher comprises a casing, wherein a first-stage feed opening is formed in the upper end of the casing; a crushing cutter is arranged in a position below the first-stage feed opening; first-stage rock crushing rollers and second-stage rock crushing rollers are sequentially arranged at the positions below the crushing cutter; screen cloths are arranged below the second-stage rock crushing rollers; the casing is provided with a sporting opening; a second-stage feed opening is formed in the same side; an elevating device is arranged at a position between the sorting opening and the second-stage feed opening; and a discharge opening is formed in the casing. According to the mine rock crusher disclosed by the invention, by adoption of a multistage crushing mode, the crushing degree of rocks is improved; and the lower-side screen cloth is used for screening, so qualified products are outputted, then unqualified products are crushed for the second time, and cycle machining for multiple times is performed. Meanwhile, the screen cloth disclosed by the invention adopts a mode of combining two screen cloths; and by adjustment of relative positions of the two pieces of screen cloths and change of mesh size of a screen cloth group, multiple output sizes are obtained.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a mining rock rolling machine with adjustable discharge size. Background technique [0002] During mining operations, it is often encountered that large stones need to be broken into small pieces for subsequent processing and transportation. The traditional processing methods mostly rely on gravity gouging, which is time-consuming, laborious and inefficient. Later, the market A kind of stone crusher appeared in the world, which crushes stones through mechanical power, which greatly improves the processing efficiency. [0003] However, most of the existing crushers on the market currently adopt the primary crushing method, the degree of crushing of stones is low, and the size of the finished product particles cannot be controlled, so the quality of the processed products is poor. Contents of the invention [0004] The technical problem to be solved by the present inven...
