Reasonable control of the balance of the feeding quantity of the two-stage crusher

How to separate the particle size in the material by two-stage crusher: crushing includes crushing and grinding, which is an important link in mineral processing production Under the action of external force, the particle size of bulk material decreases, and the intergrowth body breaks, resulting in the increase of mineral dissociation However, crushing will produce particles, which will cause the mineral dissociation and increase the dissociation However, the pulverization will produce particles, and the possibility of over pulverization may not be fully dissociated and the over pulverization is serious, which will reduce the ore dressing recovery and concentrate grade The required size of dissociation depends on the distribution size and separation method of useful minerals and gangue minerals in the ore The finer the inlay size is, the finer the ore is required to be crushed As far as the grinding process is concerned, the more complete the separation of useful minerals, the better the separation effect of useful minerals According to the particle size characteristics of the products formed in the process of particle crushing and the difference in the force application mode of the two-stage crusher equipment used in the process, the ore can be crushed into four stages: crushing, grinding, ultra-fine grinding and ultra-fine grinding There is a further division between crushing and grinding
With the overall progress of the crusher industry, we should seize the opportunity to improve our core competitiveness in the development and production of large crusher jaw crusher, hammer crusher, roll crusher, impact crusher, fine crusher, heavy hammer crusher, mobile crusher station, metal crusher, two-stage crusher, fine crusher and Zui new crusher Maintain a strong position
The two-stage crusher is the same as the hammer crusher It also uses the principle of impact to crush materials Its main working parts include the impact plate of the plate hammer After the materials enter the crushing chamber, there are double forces of the plate hammer and the impact plate, which make the materials fully impacted, impacted, rubbed and crushed Although the outlet of the two-stage crusher is not There is a grate plate device that is easy to block, but sometimes it may cause the blocking phenomenon of the two-stage crusher due to improper operation or other reasons What measures should be taken to deal with the blocking phenomenon? When the two-stage crusher is working, there may be many factors that cause the blocking phenomenon of the crusher, among which the main factors of Zui are too much feed, unreasonable conveying equipment and so on When the feed quantity of the two-stage crusher exceeds the required feed quantity, the operation of the two-stage crusher will result in the failure of the conveying speed of the conveying device, resulting in a large number of piles in the crushing cavity due to the adverse transport of materials, thus forming the blocking phenomenon of the two-stage crusher The key to solve this problem is to control the balance of the feed quantity reasonably according to the feed requirements of the two-stage crusher, Avoid blocking the crusher by feeding too much material Another main reason for the blocking phenomenon of the price of the two-stage crusher is that the installation position of the conveying device after the crusher is unreasonable The position of the conveying device of the two-stage crusher after crushing shall be reasonable, neither too high nor too low When the installation position of the conveying device is too high, it is close to the discharge port of the crusher However, the two-stage crusher is a crushing mechanism with strong production capacity, so the discharge volume is relatively large If the distance between the conveying device and the discharge port is too close, the buffer space when discharging is insufficient , it is easy to form accumulated materials, causing the blocking of the two-stage crusher However, the installation of the conveying device should not be too low In that case, when the crusher is discharging, because the distance between the discharge port and the conveying device is too large, the material will crush the storage device of the conveying device Although the installation of the conveying device is too low to cause the blocking phenomenon of the crusher, it is easy to cause the breaking phenomenon of the crusher, which is also a very unfavorable performance in the crushing production line 。
