Detailed Description
Referring to fig. 1-4, the dust removal feed back device for ore crushing of the present invention comprises a jaw crusher 1, a hammer crusher 2 and a conveyer belt 3 arranged between the jaw crusher and the hammer crusher, wherein a pulse type dust remover 4 is arranged above the conveyer belt 3; the discharge port of the jaw crusher 1 and the feed port of the hammer crusher 2 are both provided with dust extraction covers 5, and a dust removal pipeline 6 is connected between the pulse type dust remover 4 and the dust extraction covers 5.
The discharging port of the lower end of the pulse type dust remover 4 is detachably connected with a speed reducing component 7, and the distance between the discharging port of the speed reducing component 7 and the surface of the conveying belt 3 is 1-2cm. The speed of falling dust is reduced through the speed reducing assembly, and meanwhile, when the distance between the discharge port of the speed reducing assembly and the surface of the conveying belt is 1-2cm, the stroke of the powder leaving the speed reducing assembly is small, and dust is not easy to raise.
In this embodiment, the dust extraction hood 5 comprises a fixed bracket 5a respectively fixed at the discharge port of the jaw crusher 1 and the feed port of the hammer crusher 2, and the dust removal pipeline 6 is connected to the fixed bracket 5 a.
