Description

Technical Field

[0001] The utility model relates to the technical field of ore crushing, and more specifically, the utility model relates to an ore crushing device. Background Art

[0002] Ore crushing is an important process in mineral processing. The purpose is to crush the ore into appropriate particle sizes for subsequent ore dressing, smelting or other uses. Ore crushing devices are the main equipment for realizing ore crushing, and their types and structures are diverse. Common ones include jaw crushers, cone crushers, impact crushers, roll crushers, etc.

[0003] Existing ore crushing devices usually use the extrusion, shear or impact force between two relatively moving crushing parts of the crusher to crush the ore. Although this method can achieve a certain crushing effect, there are also some problems and deficiencies. For example, the crushing efficiency and quality are not high because the gap between the crushing parts of the crusher is fixed and cannot be adjusted according to different ore properties and requirements, resulting in uneven particle sizes of the crushed ore, not meeting the requirements, or incomplete crushing, requiring multiple crushings, increasing the crushing time and cost. The crushing process is unstable and unreliable. The crushing parts of the crusher are prone to jamming or blocking, resulting in the interruption or stop of the crushing process, requiring manual intervention or cleaning, reducing the crushing efficiency and safety.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model crushes ores through a crushing cylinder, a rear crushing roller, cutting edges, a front crushing roller, a rotating motor one and a rotating motor two, and utilizes the dual effects of centrifugal force and roller pressure to crush ores, improving the crushing efficiency and quality. When the ores rotate at a high speed in the crushing cylinder, they are not only affected by the centrifugal force, causing the ores to be strongly impacted and rubbed against the inner wall surface of the crushing cylinder cavity, resulting in the crushing of the ores, but also affected by the roller pressure. When the ores pass through the gap between the front crushing roller and the rear crushing roller, they are squeezed and ground by the cutting edges, leading to further crushing of the ores. In this way, all-round crushing of the ores is achieved, making the particle size of the crushed ores more uniform and more in line with requirements. Moreover, since the rotation of the crushing cylinder is realized through the rotating motor one and the transmission belt, the rotation speed and power of the rotating motor one can be adjusted according to different ore properties and requirements to achieve the best crushing effect and energy consumption. At the same time, the rotation of the crushing cylinder can also prevent the front crushing roller and the rear crushing roller from getting stuck, ensuring the smoothness and continuity of the crushing process, thereby reducing the downtime and failures during the crushing process and improving the reliability and safety of crushing.

[0014] 2. The utility model can adjust the gap between the front crushing roller and the rear crushing roller through an adjusting motor, a lead screw, a sliding block, a vertical plate, a placement frame, a slider one, a slider two, a slideway one and a slideway two, increasing the flexibility and adaptability of crushing. Because the gap between the front crushing roller and the rear crushing roller can be adjusted by the adjusting motor, the adjusting motor is a motor that can control the rotation speed and direction. Its function is to drive the lead screw to rotate, thereby adjusting the position of the sliding block on the lead screw, and then driving the vertical plate to move back and forth in the chute, ultimately changing the relative positions of the front crushing roller and the rear crushing roller with the crushing cylinder, so as to adjust the gap between the front crushing roller and the rear crushing roller to adapt to different ore properties and requirements and improve the crushing effect and quality. During the process of the adjusting motor adjusting the gap, the slider one and the slider two will also slide in the inner cavities of the slideway one and the slideway two, thus realizing the dynamic adjustment of the gap between the front crushing roller and the rear crushing roller, adapting to ores of different sizes and hardnesses, and increasing the applicable range and flexibility of the equipment.
