Problems solved by technology

[0002] After the ore is mined, it needs to be crushed and processed to facilitate subsequent transportation and processing. In the traditional ore processing process, the ore crusher produces a large amount of dust during the crushing process, and the dust overflows from the crusher, forming a lot of dust, which not only pollutes The working environment threatens the health of workers, and also causes damage to the surrounding ecological environment, and even pollutes groundwater. This application provides an ore crushing device with a dust suppression mechanism, which reduces the occurrence of dust overflow and reduces environmental pollution and damage

Embodiment 1

[0021] see Figure 1-3 , in the embodiment of the present invention, a kind of ore pulverizing device that contains dust-reducing mechanism, comprises pulverizing cylinder 1 and grinding roller 8; Said pulverizing cylinder 1 is the cone-shaped hollow cylinder of upper width and lower narrow, and pulverizing cylinder 1 is provided with grinding roller 8. There is a grinding shell 9 on the outside of the grinding roller 8, and the grinding shell 9 is fixedly connected with the inner wall of the grinding cylinder 1; the lower end of the grinding roller 8 is fixedly connected with a rotating shaft 10, and the rotating shaft 10 extends to the bottom of the grinding cylinder 1 and rotates through the bearing seat Connected with a base; the rotating shaft 10 is sleeved with a central bevel gear 11, the central bevel gear 11 is engaged with a left bevel gear 12, and the left bevel gear 12 is fixedly connected with the output shaft of a driving motor 13, and the driving motor 13 drives ...

Embodiment 2

[0025] The difference between this embodiment and Embodiment 1 is that in order to further ensure the speed and effect of ore crushing, an eccentric extrusion disk 6 is arranged above the grinding roller 8, and a connecting shaft is fixedly connected to the peripheral edge of the eccentric extrusion disk 6, and the lower end of the connection shaft It is fixedly connected with the center of the upper end surface of the grinding roller 8, that is, when the grinding roller 8 rotates and grinds, the eccentric extrusion disc 6 is driven to make a circular motion through the connecting shaft, and an annular impact plate 7 is arranged on the outside of the eccentric extrusion disc 6, 7 is fixedly connected with the inner wall of the crushing cylinder 1, and the eccentric extrusion disc 6 cooperates with the impact plate 7 to preliminarily crush and crush the ore to reduce the size of the ore particles, so as to prevent the ore particles from being too large and unable to enter the gap...

Abstract

The invention discloses an ore crushing device with a dust falling mechanism. The ore crushing device comprises a crushing cylinder and a grinding roller; the crushing cylinder is a conical hollow cylinder with a wide upper part and a narrow lower part; a discharging pipe is embedded in the central axis of the crushing cylinder; the upper part of the crushing cylinder is communicated with a blastpipe; and the blast pipe is tangentially communicated with the crushing cylinder. Through the arrangement of the crushing cylinder which is wide in upper part and narrow in lower part and is in a conical cylinder shape, a central pipe extending into the crushing cylinder, the blast pipe and a blast cylinder linked with a rotating shaft, the rotational flow is formed in the crushing cylinder for cyclone sedimentation and collection of dust, so the random floating of the dust is avoided, and a good dust falling effect is achieved; through the arrangement of an eccentric extrusion disc, an impactplate and a guide cover, the ore crushing speed and effect are guaranteed; through the arrangement of a discharging box, a columnar cavity and an impeller roller, while quantitative discharging is conducted, the crushing effect is guaranteed, and the dust is prevented from overflowing from the feeding hopper, thereby further improving the dust falling effect.

Description

technical field [0001] The invention relates to the field of mining processing equipment, in particular to an ore crushing device with a dust suppression mechanism. Background technique [0002] After the ore is mined, it needs to be crushed and processed to facilitate subsequent transportation and processing. In the traditional ore processing process, the ore crusher produces a large amount of dust during the crushing process, and the dust overflows from the crusher, forming a lot of dust, which not only pollutes The working environment threatens the health of workers, and also damages the surrounding ecological environment, and even pollutes groundwater. This application provides an ore crushing device with a dust suppression mechanism, which reduces the occurrence of dust overflow and reduces environmental pollution and damage. Contents of the invention [0003] The object of the present invention is to provide an ore crushing device with a dust-reducing mechanism to so...
