Embodiment Construction

[0015] Further detailed explanation through specific implementation mode below:

[0016] Such as figure 1 , figure 2 and image 3 The limestone crushing device shown includes a casing 1, a crushing rod and a negative pressure fan 7. The top of the casing 1 is provided with a feeding port 11, and the bottom is provided with a dust removal port 12; the crushing rod is arranged inside the casing 1 and located at the feeding port 11. Directly below, the negative pressure fan 7 is installed at the dust removal port 12. There are screening mechanisms on both sides and below the crushing rod. The screening mechanism includes an elastic screening net 4 made of steel foil. The connected rotating roller 5 and the screening net 4 are connected to the outer surface of the rotating roller 5 through transmission. The screening net 4 and the rotating roller 5 form a U-shaped transmission channel. A plurality of screening nets 4 are connected side by side on the rotating roller 5 , and a ...

Abstract

The invention discloses a limestone crushing device in the mining mechanical field. The limestone crushing device comprises a shell, a crushing roller and a negative-pressure fan; a feed port is formed above the shell, and a dust removing port is formed below the shell; the crushing roller is arranged in the shell, and is positioned rightly below the feed port; the negative-pressure fan is mountedin the dust removing port; screening mechanisms are arranged on two sides and the lower side of the crushing roller; the screening mechanisms comprise screening nets made of steel foils and with elasticity; a rotating roller, fixedly connected through a fixed frame, is arranged in the shell; the screening nets are in transmission connection to the outer surface of the rotating roller; the screening nets and the rotating roller form a U-shaped conveying channel; a cleaning column matched with meshes of the screening nets is arranged on the surface of the rotating roller; multiple screening nets are connected to the rotating roller side by side; and cutters are arranged between the adjacent screening nets, and are fixed on the surface of the rotating roller. The problem of worse dust accumulation of limestone remained in the crushing device can be effectively prevented; and the crushing device can normally work.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a limestone crushing device. Background technique [0002] Lime ore is calcined to form quicklime. The composition of quicklime is calcium oxide. It is a common building material and the main raw material for processing cement. Generally, it needs to be crushed before using limestone. In order to facilitate transportation and reduce dust generation, only need Limestone is broken into small particles, and then crushed and ground before being produced into cement. Some of the existing limestone crushing equipment does not consider the setting of dust removal, which often results in a very poor environment for the entire limestone kiln, resulting in serious pollution; even now some production machines adopt dust removal mechanisms, generally with water mist dust removal and load In the pressure dust removal method, since the limestone is composed of calcium oxide, if water...
