Abstract

The invention discloses a screening and crushing all-in-one machine for coal mining, and relates to the technical field of screening and crushing all-in-one machines. The screening and crushing all-in-one machine for coal mining comprises a case, an iron removal device is fixedly mounted at the left end in the case, and a first-stage screening and crushing device is fixedly mounted in the case and on the right side of the iron removal device; and a second-stage screening and crushing device is fixedly installed in the case and located on the right side of the first-stage screening and crushing device, and a conveying device is fixedly installed at the lower end in the case. The iron removal device is arranged to be a rotatable device, the iron removal area is increased, the iron removal efficiency is improved, and it is guaranteed that a large number of coal briquettes cannot stay on an iron removal plate when entering the device, so that the situation that the whole machine operates abnormally is avoided, a first-stage crushing device is additionally arranged before crushing of a crushing wheel, and extrusion and preliminary crushing are conducted between a movable crushing plate and a fixed crushing plate; and the size of the coal briquettes is reduced, so that the size of the coal briquettes before entering the crushing wheel is reduced, and abnormal shutdown of the whole machine due to clamping stop between the crushing wheel and a screening roller caused by overlarge size of the coal briquettes is avoided.

Description

technical field [0001] The invention relates to a screening and crushing integrated machine, relates to the technical field of screening and crushing integrated machines, in particular to a screening and crushing integrated machine for coal mine development. Background technique [0002] The screening and crushing integrated machine is a combination of a screening machine and a crusher. It is widely used in power plants, mines, coal, metallurgy, coking, chemical industry, raw materials, non-ferrous metals and other coarse and fine crushing industries.
