The ore is broken up by the coarse grinding wheel 102 and falls downward. The dust shield 5 prevents the broken ore from falling directly into the bottom of the machine. The ore is broken up again by the fine grinding wheel 200 and falls downward. The grinding mechanism 3 grinds the ore into powder. In order to prevent the powder from adhering to the wheel body, the scraper 302 is used to scrape off the ore powder. When the equipment is running, the dust removal port 104 collects the dust generated when the ore is crushed. The inhaled dust is collected into the dust collecting equipment through the dust removal pipe 105. The ore powder is squeezed into a fixed shape by the extrusion device 400 and then transported to the next device by the conveyor belt 404.

[0028] Specifically, by Figure 2The base of the dust shield device 5 of the present invention is fixed to the inner wall of the housing 100, and the baffle is made of elastic material and connected to the inner wall of the housing 100 through a spring. The elastic material can prevent the dust shield device 5 from being damaged by falling ore particles, and the use of a spring to connect the inner wall of the housing can improve the rebound ability of the device and extend the service life of the device.

[0029] Specifically, by Figure 2 Dust removal pipes 105 are provided on both sides of the outer shell 100, and the upper ends of the dust removal pipes 105 are connected to the dust removal port 104. The dust removal pipes 104 are used to transmit the dust collected by the dust removal port 105.

The second cover door is an upwardly opened metal door, and a link 402 is provided at the lower end to connect with the housing 100, so as to facilitate cleaning the inside of the equipment and replacing the extrusion mold, and the third cover door 403 is used to clean the debris dropped when the conveyor belt is running.

[0033] Specifically, by Figure 6 The extrusion device 400 of the present invention is provided with a dustproof plate 500 at the top, and the dustproof plate 500 is supported by an arc-shaped support frame 501, and the support frame 501 is in contact with the driving wheel 502. Spraying ports 503 and extrusion molds 504 are symmetrically provided on both sides of the extrusion device 400. The extrusion mold 504 is connected to a hydraulic press 505. A buffer baffle 506 with elastic force is provided at the bottom of the extrusion device 400. The dustproof plate 500 can separate the extrusion device 400 from the outside to prevent the coagulant from being sprayed from the spray port 503 in the extrusion device 400 and splashing onto the mold. At the same time, a support frame 501 is connected under the dustproof plate, and the driving wheel 502 is in contact with the support frame 501. The dustproof plate 500 is controlled to open and close during rotation. The dustproof plate 500 opens and closes downward to allow the machine to continue to operate during extrusion molding. The extrusion mold 504 is driven by the hydraulic press 505 to perform extrusion work. The buffer baffle 506 plays a buffering role to prevent the extruded ore from falling onto the conveyor belt and deforming.

[0034] Specifically, the ore crushing and shaping method of the present invention includes the following steps: the equipment is started, the dust removal port starts to absorb dust, the conveyor belt is started, the unprocessed ore falls into the coarse grinding mechanism from the drop port, and after being processed by two sets of coarse grinding wheels, it falls into the fine grinding mechanism together with the ore particles collected by the dust blocking device, and after being processed by two sets of fine grinding wheels, it falls into the grinding mechanism together with the ore particles collected by the dust blocking device, and after being processed by two sets of grinding wheels, it falls into the shaping mechanism, the scraper scrapes the ore powder attached to the grinding wheel and falls into the shaping mechanism, the dust plate closes after the ore powder falls into the shaping mechanism, the spray port sprays condensate, the ore powder is moistened and then extruded and shaped by the extrusion device, and the ore powder is buffered by the buffer baffle after being extruded and shaped in the previous step and then falls onto the conveyor belt to be transmitted to the subsequent device.

[0035] Working principle: The present invention is a method and device for crushing and shaping ore, which can be used in conjunction with an ore conveying device or can be used alone. When in use, the ore falls into the device from the top drop port 101, passes through the coarse grinding wheel 102, the fine grinding wheel 200 and the grinding wheel 300, and is finally turned into ore powder and falls into the extrusion device 400. The dust collected by the dust removal port 104 is transported to the dust collection device through the dust removal pipe 105. The dust blocking device 5 in the device can effectively prevent the ore from splashing. Before the extrusion device 400 is operated, The driving wheel 502 drives the support frame 501 to make reciprocating motion to close the dustproof plate 500. After closing, the spray port 503 sprays the coagulant on the ore powder. The two extrusion dies 504 are driven by the hydraulic press 505 to extrude the ore powder. After forming, the ore powder falls onto the conveyor belt through the buffer baffle 506 and is transported to the subsequent device. The ore residue inside the equipment can be cleaned by opening the first cover door 301, the second cover door 401 and the third cover door 403. After opening the second cover door 401, the extrusion die 504 can be replaced.
