Description

Technical Field

[0001] The invention relates to the technical field of ore crushing, in particular to a multi-stage continuous ore crusher. Background Art

[0002] Ore is usually composed of a variety of minerals. Crushing can separate useful minerals from gangue minerals as much as possible, providing a good material basis for subsequent mineral processing operations (such as flotation, gravity separation, magnetic separation, etc.). It improves the recovery rate and concentrate grade of mineral processing, and the volume of the crushed ore is reduced, which is convenient for transportation and storage.

[0003] There are many different types of ore crushers on the market, the most common of which is the hammer crusher. The motor drives the rotor to rotate at high speed, and the material is impacted, sheared and torn by the high-speed rotating hammer head, causing the material to be crushed. However, when the hammer crusher only uses one crushing chamber for crushing, the crushing effect is not ideal, so additional crushing chambers are added to crush the ore continuously for multiple times.

[0004] Multi-stage crushers can crush ore more thoroughly, but the ore is crushed by crushing rollers in multiple crushing bins. The hammer head is fixedly installed on the outer surface of the crushing roller. The force of the impact is determined by the rotation speed driven by the motor. If you want to crush it more thoroughly, you need a more powerful motor, which is not energy-saving and increases the cost of the motor and wastes resources. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example

[0035] See also Figure 1-Figure 7 As shown, the purpose of this embodiment is to provide a multi-stage continuous ore crusher, including a crusher shell 1, a base 2 is installed at the bottom of the crusher shell 1, a driving motor 21 and a driving motor 22 are arranged on the top of the base 2, a crushing bin 11 and a crushing bin 12 are arranged inside the crushing shell 1, a crushing roller 3 is rotatably installed inside the crushing bin 11, a crushing rod 31 is fixedly installed on the outer surface of the crushing roller 3, and a plurality of crushing blocks 32 are fixedly installed on the outer surface of the crushing rod 31, the crushing rod 31 is used to crush the ore, and the crushing blocks 32 can increase the contact points with the outer surface of the ore.

[0036] By energizing the driving motor 1 21 and the driving motor 2 22, the crushing rollers 1 3 and 2 4 in the crushing bin 1 1 and the crushing bin 2 12 are driven to rotate respectively, so that the ore can be crushed in multiple stages. The crushing rod 1 31 installed on the outer surface of the crushing roller 2 4 can rotate together with the crushing roller 3 to crush the ore. The outer surface of the head of the crushing rod 1 31 is provided with a plurality of protruding crushing blocks 32, which can increase the impact points of the crushing rod 1 31 on the ore, so as to improve the ore crushing efficiency. The two motors drive the two crushing bins to work respectively, so as to improve the ore crushing effect.

[0037] A feed port 13 and a discharge port 14 are respectively provided at the top and bottom of the crusher housing 1. An automatic closing component 5 is provided inside the feed port 13. The automatic closing component 5 can be closed after the ore enters the crusher housing 1 to avoid splashing of the crushed ore.

[0038] When the crusher is crushing, the crushed ore will have debris splashing, causing damage to the workers. The automatic closing component 5 can automatically close the feed port 13 after the ore is put into the crusher to avoid the ore splashing.

[0039] First of all, considering the problem that when the ore is crushed, there will still be blocky ore inside after it is crushed by the crushing roller, Figure 2-Figure 5 , the internal structure of the crushing bin 12 is disclosed, the crushing bin 12 is rotatably installed with a crushing roller 4, the outer surface of the crushing roller 4 is sleeved with a rolling disc 41, and a plurality of rolling discs 41 are arranged on the outer surface of the crushing roller 4, and the plurality of rolling discs 41 can crush and crush the ore, and a crushing rod 42 fixedly installed on the outer surface of the crushing roller 4 is arranged in the middle of the plurality of rolling discs 41, and a rotating block 43 is rotatably installed on the side wall of the crushing rod 42, and the crushing roller 4 drives the rotating block 43 on the crushing rod 42 to rotate, so that the rotating block 43 hits and crushes the ore into small particles;

[0040] The inner walls of the crushing bin 1 1 and the crushing bin 2 12 are fixedly mounted with crushing plates 6 , which cooperate with the rolling disc 41 to crush the ore.

[0041] The crushing bin 12 can further crush the small pieces of ore that fall after being crushed by the crushing bin 11. The driving motor 22 drives the crushing roller 4 to rotate. The crushing roller 4 drives the crushing rod 42 and the rotating block 43 installed on the outer surface to rotate, so as to hit and crush the fallen ore, and make the ore after hitting splash onto the inner wall of the crushing bin 12. The ore is further crushed and crushed by the crushing plate 41, and the ore is crushed more thoroughly. The crushing rod 42 drives the rotating block 43 to further rotate, which can greatly increase the impact force of the rotating block 43 on the ore, and the impact force is greater, which greatly reduces the situation where block ore is mixed in the ore after crushing. There is no need to crush the crushed ore again, which improves the crushing effect and is more energy-saving and efficient.

[0042] It should be noted that the crushing plate 6 installed on the inner wall of crushing bin 11 and crushing bin 2 12 can cooperate with crushing roller 1 3 and crushing roller for crushing, and the crushing plate 41 can cooperate with the crushing plate 6 to crush the ore between the crushing plate 6 and the crushing plate 41, and the crushing plate 6 can also increase the crushing effect and protect the inner wall of the crusher.

[0043] Secondly, considering how the drive motor is connected to the pulverizer to make the pulverizer work, show Figure 1 and Figure 2 The driving motor 1 21 and the driving motor 2 22 are respectively arranged on both sides of the pulverizer shell 1, one side of the crushing roller 3 penetrates the pulverizer shell 1 and is connected to the driving motor 1 21 through a crawler belt, and one side of the crushing roller 2 4 penetrates the pulverizer shell 1 and is connected to the driving motor 2 22 through a crawler belt. The driving motor 1 21 and the driving motor 2 22 are used to drive the crushing roller 1 3 and the crushing roller 2 4 to rotate.

[0044] The crushing bin 11 is arranged below the feed port 13 to crush the large pieces of ore falling from the feed port 13. The crushing bin 2 12 is arranged below the crushing bin 11 to further crush the small pieces of ore crushed by the crushing bin 11. The discharge port 14 is arranged below the crushing bin 12 to discharge the crushed ore. The top of the base 2 is provided with a leakage port 7, which is arranged below the discharge port 14 to collect and process the crushed ore in cooperation with the discharge port 14.

[0045] By installing and placing the driving motor 1 21 and the driving motor 2 22 on both sides of the crusher shell 1 on the top of the base 2, the driving motor 1 21 can be connected to the crushing roller 1 3 through the track from the front, and the driving motor 2 22 can be connected to the crushing roller 2 4 through the universal track from the back, so that the crushing roller 1 3 and the crushing roller 2 4 can rotate more smoothly. The ore fed from the feed port 13 enters the interior of the crushing bin 1 1 for crushing, and then enters the interior of the crushing bin 2 12 for further crushing. The crushed ore is discharged and collected by the discharge port 14 at the bottom of the crushing bin 2 12 and the leakage port 7 on the base 2.

[0046] Finally, considering how the automatic closing assembly 5 closes the feed opening 13, Figure 6 , the specific structure of the automatic closing component 5 is disclosed, the automatic closing component 5 includes an arc groove 501 opened on the inner wall of the feed port 13, there are two arc grooves 501, the two arc grooves 501 are respectively opened on both sides of the inner wall of the feed port 13, a sliding block 502 is slidably installed inside the arc groove 501, a reset spring 503 is installed at the bottom of the sliding block 502, the bottom of the reset spring 503 is installed at the bottom of the inner wall of the arc groove 501, a closing plate 504 is fixedly installed on the outer wall of the sliding block 502, the closing plate 504 is set in the middle of the two arc grooves 501, and can be automatically reset and closed after opening and closing by the sliding block 502 and the reset spring 503.

[0047] Two closing plates 504 are provided, and the two closing plates 504 are symmetrically distributed inside the feed port 13. The middle of the two closing plates 504 can be opened downward to put the ore in.

[0048] By opening two arc grooves 501 on both sides of the inner wall of the feed port 13, the reset spring 503 and the sliding block 502 can be installed inside the arc groove 501, so that the reset spring 503 can reset the sliding block 502 sliding downward, and a closing plate 504 is fixedly installed between the two sliding blocks 502, and two closing plates 504 are symmetrically distributed. After the ore is put into the feed port 13, the two closing plates 504 are pressed downward to open and close. After the ore falls into the crushing bin 11, the closing plate 504 is reset by the reset spring 503, and the feed port 13 is closed again, so as to achieve the effect of automatically closing the feed port 13 and avoiding the splashing of debris from the crushed ore.

[0049] In summary, the working principle of this solution is as follows:

[0050] When the ore is crushed, the driving motor 1 21 and the driving motor 2 22 are started to drive the crushing roller 1 3 and the crushing roller 2 4 to rotate, and the ore is put into the crusher housing 1 from the feed port 13, so that the ore enters the crushing bin 11, and the crushing rod 31 on the outer surface of the crushing roller 3 rotates to crush the ore. The crushing block 32 installed at the head end of the crushing rod 31 can increase the collision point with the ore, which has a better crushing effect on the ore. The ore after preliminary crushing enters the crushing bin 12 and rotates at high speed. The movable crushing rod 42 and the rotating block 43 can beat the incoming ore into granular blocks, and beat the ore between the crushing plate 6 and the rolling plate 41 on the inner wall of the crushing bin 12, and the rolling plate 41 will crush the ore into powder particles again, so as to achieve the effect of hitting, rolling and crushing the ore, making the ore crushing more thorough. The crushing rod 42 drives the rotating block 43 to rotate further, which can greatly increase the impact force of the rotating block 43 on the ore, the impact force is greater, the energy consumption of the motor is saved, and the crushing effect is better;

[0051] When the ore is put into the crusher housing 1, after the ore is put into the feed port 13, the two closing plates 504 are squeezed downward to open and close, and the ore falls into the crushing bin 11. The closing plate 504 is reset by the reset spring 503, and the feed port 13 is closed again, so as to achieve the effect of automatically closing the feed port 13 and avoiding the splashing of the crushed ore debris.
