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

This proposal discloses a limestone crushing device in the field of mining machinery, including a casing, a crushing rod and a negative pressure fan. The top of the casing is provided with a feeding port and the bottom is provided with a dust removal port; Directly below the feeding port, the negative pressure fan is installed at the dust removal port, and a screening mechanism is provided on both sides and below the crushing rod, and the screening mechanism includes an elastic screening net made of steel foil. There is a rotating roller fixedly connected by a fixed frame, and the screen mesh is driven and connected to the outer surface of the rotating roller. The screening mesh and the rotating roller form a U-shaped transmission channel. The surface of the rotating roller is provided with a cleaning column that fits the mesh of the mesh. A plurality of screening screens are connected side by side on the rotating roll, and a cutter is arranged between adjacent screening screens, and the cutting knife is fixed on the surface of the rotating roll, which can effectively prevent the problem of serious dust accumulation of residual limestone in the crushing device, so that the crushing device able to 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...
