In the process of producing molybdenum oxide blocks used as steelmaking additives, some unformed waste products will be generated during the pressing and drying process. These waste products usually need to be crushed and ground before reuse, so a pulverizer is needed in this process to crush them.
[0003] In the prior art, the crushing motor in the crusher works, driving the crushing rollers to move. As the two crushing rollers mesh with each other, the molybdenum oxide is initially crushed, and the ore is pre-crushed into pieces of approximately the same size, which is convenient for subsequent crushing by the crushing components, thereby improving the crushing efficiency and crushing effect.
[0004] However, the existing crushers have the following defects: since the top of the crushing device uses two crushing rollers, when larger materials are put in for crushing, the materials will stay on the top of the two crushing rollers for a long time, which not only blocks the subsequent materials and reduces the crushing efficiency, but also easily produces debris during the crushing process of large particles, which has a certain impact on the safety of the surrounding workers.
[0005] In order to solve these problems, a molybdenum oxide production multi-roller crusher is needed that can prevent the material from accumulating at the top of the crusher, can crush quickly, and can continuously feed without being affected. Utility Model Content

After the molybdenum oxide is crushed into particles by the first crushing roller 602 and the second crushing roller 702, it falls into the second crushing chamber and is further crushed by the third crushing roller 703 and the first crushing roller 602. Finally, the material after two crushings is crushed again by the two fourth crushing rollers 704, so that the required crushed materials can be graded and crushed, avoiding the accumulation of materials on the top of the machine room 1, so that the materials can be continuously fed and can avoid the ejection of materials, thereby improving the crushing efficiency of the materials and improving the safety of the surrounding personnel.
[0031] As attached Figure 4 As shown, the first crushing mechanism 6 includes a first motor 601, and the first motor 601 is installed on a side plate 5;
[0032] The first crushing roller 602 has one end connected to the output end of the first motor 601 , and the other end of the first crushing roller 602 is rotatably connected to the other side plate 5 .
[0033] During specific implementation, the first motor 601 is operated to rotate the first crushing roller 602, and the rotation direction of the first crushing roller 602 is opposite to that of each crushing roller in the second crushing mechanism 7, so that the first crushing mechanism 6 cooperates with the second crushing mechanism 7 to quickly crush the material and transport it to the bottom of the silo 1 to avoid rebound of the generated debris.
[0034] Specifically, according to the structure of the machine bin 1, the machine bin 1 has the function of a material baffle. The second crushing roller 702 on one side rotates counterclockwise, and the two first crushing rollers 602 in the middle rotate clockwise, so that the two first crushing rollers 602 respectively and the adjacent second crushing rollers 702 synchronously squeeze the material downward for crushing.
[0035] As attached Figure 4 As shown, the second pulverizing mechanism 7 includes a second motor 701, and the second motor 701 is mounted on a side plate 5;
[0036] A second crushing roller 702, one end of which is connected to the output end of the second motor 701, and the other end of which passes through another side plate 5;
[0037] A third crushing roller 703, wherein the third crushing roller 703 is disposed at the bottom end of the second crushing roller 702;
[0038] A fourth crushing roller 704, wherein the fourth crushing roller 704 is arranged at the top of the discharge port 4;
[0039] A plurality of pulleys 705, each of which is mounted on one end of the second crushing roller 702, the third crushing roller 703 and the fourth crushing roller 704;
[0040] A plurality of belts 706 are provided, and each of the belts 706 is connected and cooperated with two corresponding pulleys 705 .
[0041] The two second crushing rollers 702 are respectively arranged on one side of the top end of the corresponding first crushing roller 602 , and a first crushing cavity is formed between the two second crushing rollers 702 and the corresponding first crushing roller 602 .
[0042] The two third crushing rollers 703 are respectively arranged on one side of the corresponding first crushing roller 602, and a second crushing cavity is formed between each third crushing roller 703 and the corresponding first crushing roller 602, and the diameter of the second crushing cavity is smaller than the diameter of the first crushing cavity.
[0043] The two fourth crushing rollers 704 are both arranged at the bottom ends of the two first crushing rollers 602 , and the two fourth crushing rollers 704 are cooperatively arranged at the top end of the discharge port 4 .
[0044] During specific implementation, two second motors 701 are operated so that the two second crushing rollers 702 connected respectively rotate synchronously with the corresponding first crushing rollers 602, so that the material in the first crushing chamber is squeezed downward and crushed, so that the material after the first crushing quickly falls into the second crushing chamber, and is connected by a belt 706 and rotated synchronously with the second crushing roller 702 to the third crushing roller 703 to cooperate with the adjacent first crushing roller 602 to crush the material entering the second crushing chamber again. Finally, the crushed material falls from the second crushing chamber onto the two fourth crushing rollers 704, and is finely crushed by the two fourth crushing rollers 704 to obtain material of the required particle size.
[0045] It should be noted that: Figure 4 The orientation of the crushing knives installed on each crushing roller is only for illustration and cannot represent the orientation of the crushing knives in the actual object.
[0046] Working principle of the utility model: after the materials in the molybdenum oxide production process are crushed by using the multi-roller crusher for molybdenum oxide production, the materials to be crushed are placed from the feed port 3 under the guide plate 8 to guide the materials to both sides, and enter the corresponding first crushing chamber respectively. After being crushed into appropriate particles by the first crushing roller 602 and the second crushing roller 702, they fall into the second crushing chamber, and are further crushed by the third crushing roller 703 and the first crushing roller 602. Finally, the materials after the two crushings are crushed again by the two fourth crushing rollers 704, so that the materials to be crushed can be graded and crushed, avoiding the accumulation of materials on the top of the machine room 1, so that the materials can be continuously fed and the ejection of materials can be avoided, thereby improving the crushing efficiency of the materials and improving the safety of the surrounding personnel.
[0047] The utility model classifies and crushes the materials to be crushed in the production process of molybdenum oxide, thereby preventing the crushed materials from being continuously accumulated at the bottom of the crusher, thereby facilitating continuous feeding and improving the crushing efficiency of the materials. At the same time, it also prevents the crushed particles from being squeezed multiple times and rebounding, resulting in them popping out of the machine chamber 1 and causing harm to surrounding staff, thereby improving the safety of surrounding staff at work.
[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
