Description

Technical Field

[0001] The invention relates to an ore crushing processing device, belonging to the technical field of ore processing equipment. Background Art

[0002] Ore composition testing is a key technology in the fields of mineral processing, metallurgy and geological exploration. It is crucial for evaluating the value of ore, designing mineral processing procedures and subsequent metal extraction processes.

[0003] When testing the composition of ore, direct analysis is prone to errors due to the uneven composition and large particles of natural ores, so the ore needs to be crushed. Crushing is a key step to ensure the accuracy and representativeness of the analysis results. The crushed ore sample is more uniform and refined, and its contact area with the reagent is greatly increased, which effectively improves the reaction efficiency and the representativeness of the results. At the same time, modern analytical instruments also have requirements for the particle size of ore samples. Too large particles will affect the accuracy. Therefore, crushing is an indispensable preparatory work for ore composition testing.

[0004] When testing ore composition in the laboratory, it is not convenient to use large-scale equipment to crush the ore due to the small sample size. Usually, the steps for people to crush ore in the laboratory mainly include: first, manually use manual tools to break large pieces of ore into small pieces; then, for ore samples with higher particle size requirements, use a small ball mill to crush them, and for ore samples with smaller batches and lower crushing particle size requirements, use a mortar to grind them manually; when using some instruments for testing, the crushed samples also need to be manually sieved.

[0005] The ore crushing process used in the above laboratory has the following disadvantages:

[0006] 1. Manually breaking the ore into small pieces with hand tools is labor-intensive and can easily cause ore splashing and injure operators.

[0007] 2. Grinding the ore manually with a mortar is cumbersome and laborious. The mortar and ball mill cannot be finely screened after grinding, and the ore powder needs to be manually screened, which is cumbersome and there is dust damage during the screening process.

[0008] 3. The entire operation process needs to be completed manually using multiple tools at multiple workstations, the operation continuity is poor, and the ore crushing efficiency is low. Summary of the invention

The first cone 4023 is provided in three levels, and the outer dimensions of the first cone 4023 shrink toward the central axis from the bottom to the top. Fig. 9 , Fig.10 shown.

[0095] The crushing cone 403 is hollow and is provided with a shaft lining portion 4031. The output shaft 104 is coaxially connected to the crushing cone 403 through the shaft lining portion 4031.

[0107] In this embodiment, the crushing bushing 302 and the crushing cone 303 are both made of wear-resistant steel; the eccentric assembly 304 rotates with the output shaft 104, thereby continuously pushing the crushing cone 303 to approach the crushing bushing 302, and the ore between the crushing bushing 302 and the crushing cone 303 is squeezed and crushed.

At this time, the limit element 503 is in the normally closed state, and the control module 7056 can control the telescopic cylinder 704 to move; as the output shaft 104 moves axially, when the detection ring groove 1042 as a whole passes over the connecting position between the transmitter and the receiver, the other parts of the output shaft 104 block the above-mentioned light, and the receiver cannot receive the light. At this time, the limit element 503 is in the normally open state, and the control module 7056 connected thereto controls the telescopic cylinder 704 to stop moving.

[0131] In this embodiment, the type of ore is tungsten ore. When the ore is crushed, large pieces of ore are put into the hopper 201, and the ore enters the crushing module 3 from the feeding component 2. As the eccentric component 304 rotates, the crushing cone 303 continues to approach the crushing bushing 302, and the large pieces of ore are squeezed by the crushing cone 303 and the crushing bushing 302 to become small pieces of ore; further, the crushed ore enters the crushing module 4, and the crushing cone 403 rotates relative to the conical bushing 402, and the ore is squeezed by multiple groups of first cones 4023 and second cones 4032, as well as multiple groups of first grinding teeth 4025 and grinding tooth assemblies 4033 to become coarse ore powder with smaller particle size; during the crushing process, the operator can control the distance between the crushing cone 403 and the conical bushing 402 through the lifting component 7, so as to obtain coarse ore powder that meets the particle size requirements. The coarse ore powder enters the screening cylinder assembly 5, and is screened by the spiral screen plate 5023 and classified into different collection bins 5025. The finer ore dust is collected by the powder collection assembly 504. Furthermore, people judge the position of the ore powder in the collection bin 5025 through the observation window 5011, and finally use the material taking device to extract the ore powder in the collection bin 5025 through the sampling hole 5012 for detection. The buffer base 6 reduces the vibration transmission of the device as a whole to the outside world.
