TECHNICAL FIELD
[0001] The present application relates to the technical field of mining equipment, in particular to a mine ore crushing device and an ore crushing process thereof. BACKGROUND
[0002] In the field of mining and mineral processing, an ore crushing device is an indispensable key equipment. Its main function is to crush large block of mined raw ore, so that its particle size is reduced to meet the requirements of subsequent beneficiation, smelting or as a building aggregate process.
[0003] However, the existing mine ore crushing device has many shortcomings in the long-term use process. Because the crushing operation condition is poor, the core components such as the crushing roller have a fast wear rate, and frequent maintenance or replacement is required. The traditional crushing device often lacks careful consideration in structural design, and the disassembly process of its internal components is usually very tedious and complex, which not only requires various special tools, but also often requires a large amount of manpower and time, resulting in a long equipment downtime period, which seriously affects the continuity and economic benefits of the entire production line.
[0004] In addition, the crushed material usually needs to be immediately screened to separate products of different particle sizes. In the prior art, the crushing and screening functions are often completed by two independent devices, which not only increases the land area occupied by the equipment and the investment cost, but also makes the material transfer process complex and increases the energy consumption. Even some devices integrate the screening function, but the vibration mechanism often has problems such as unstable operation, low screening efficiency and excessive noise due to unreasonable design.
[0005] More seriously, a large amount of dust is inevitably generated during the crushing process of the ore under the impact and extrusion. These dusts dispersed in the operation site not only cause serious pollution to the surrounding environment, but also pose a great threat to the health of the front-line operators, and are prone to cause occupational diseases. The current market has many crushing devices that have not yet solved this problem, often lacking integrated and efficient dust removal systems, resulting in a poor on-site environment, which is difficult to meet the increasingly strict environmental protection and occupational health and safety standards.

Each of the multiple connecting rods (26) is fixedly connected to a plate (27) on its upper part, and each of the multiple plates (27) is slidably connected inside the mounting block (20).
7. The ore crushing device and ore crushing process for mining as described in claim 4, characterized in that, Limiting rods (37) are fixedly connected to both sides of the inside of the screening box (28). The two connecting blocks (36) are slidably connected to the outside of the two limiting rods (37). Buffer springs (38) are sleeved on the outside of the two limiting rods (37). One end of the two buffer springs (38) is fixedly connected to the inside of the screening box (28), and the other end of the two buffer springs (38) is fixedly connected to the right side of the two connecting blocks (36).
8. The ore crushing device and ore crushing process for mining as described in claim 2, characterized in that, Both sides of the bottom of the horizontal plate (34) are fixedly connected to sliders (35), and both sliders (35) are slidably connected inside the screening box (28).
9. A mining ore crushing device and its ore crushing process according to claim 5, characterized in that, Compression springs (25) are fitted on both sides of the two guide rods (22). One end of each compression spring (25) is fixedly connected to the inside of the fixing box (21), and the other end of each compression spring (25) is fixedly connected to the side of each guide block (23) that is far away from each other.
10. A mining ore crushing process, comprising a mining ore crushing device according to any one of claims 1-9, characterized in that, Includes the following steps: S1. First, when it is necessary to repair or replace the crushing roller (19), the protective box (2) needs to be removed. The operator holds the handles (24) on both sides and moves them to both sides, so that the guide block (23) slides along the guide rod (22). At the same time, the connecting rod (26) drives the insert plate (27) to slide out from the mounting block (20), releasing the fixing of the mounting block (20), thereby removing the entire protective box (2). After the protective box (2) is removed, the maintenance personnel turn the handle (16) so that the screw (17) rotates inside the mounting cover (13), thereby driving the clamping part (18) to move, releasing the clamping fixing of the crushing roller (19). Then, pull out the locking pin (15) that passes through the limit plate (14) and the crushing roller (19), and the two crushing rollers (19) can be easily removed from the mounting cover (13). S2. Next, after the ore is crushed, the crushed stone will fall into the screen frame (39) inside the screening box (28). Start the motor (30). The output end of the motor (30) drives the circular plate (31) and the movable plate (32) to rotate. Since one end of the movable support rod (33) is slidably connected in the movable plate (32), the rotational motion of the motor (30) is converted into the reciprocating linear motion of the movable support rod (33). The other end of the movable support rod (33) drives the horizontal plate (34) to reciprocate. The two connecting blocks (36) and the screen frame (39) at the bottom also reciprocate at high frequency. Under the continuous high-frequency shaking of the screen frame (39), the crushed stone particles smaller than the screen mesh size will pass through the screen and fall to the bottom of the screening box (28) and be discharged, while the larger stones will remain on the screen. S3. Finally, start the fan (40). The input end of the fan (40) is connected to the left side of the collection box (41). By running, it generates negative pressure in the entire dust collection system, forming a strong suction force. This suction force is transmitted to the fixed pipe (44) at the other end through the conveying hose (43) connected to the rear of the collection box (41). Multiple suction pipes (45) are connected to the fixed pipe (44). They suck the dust and air generated during the crushing process into the pipeline system. The airflow containing dust passes through the suction pipe (45), the fixed pipe (44) and the conveying hose (43) and is finally transported to the inside of the collection box (41). The dust accumulates in the collection box (41) for easy subsequent centralized cleaning.
