Description

Technical Field

[0001] The utility model relates to the technical field of ore crushing, in particular to a multi-stage ore crushing device. Background Technique

[0002] Ore materials are essential materials in the construction field. With the development of science and technology, the requirements for stone materials are getting higher and higher. Most of these stone materials need to be crushed before use, and at this time, a crushing device is required. The Chinese crushing and grinding equipment industry has fully developed into a highly competitive industry.

[0003] In the mineral processing and metal extraction industries, ore crushing is an important pretreatment step. By crushing large pieces of ore into smaller particles, the efficiency of the subsequent ore dressing process can be improved, and valuable components in the ore that are difficult to extract can be released. However, traditional single-stage crushers often cannot meet the requirements of modern industrial production for high efficiency, energy conservation, and environmental protection. Therefore, multi-stage crushing devices have emerged.

[0004] Chinese Patent (authorization announcement number: CN 211099494 U, authorization announcement date: July 28, 2020) proposed a multi-stage ore crushing device for mine development. Through the coordinated use of a first motor, a first pulley, a second pulley, a first belt, a rotating shaft, a first crushing gear, a driving wheel, a first crushing box, a stirring shaft, a second motor, a second crushing gear, a second crushing box, a second belt, and a driven wheel, it solves the problem that when the existing crushing device is in use, since most of them are single-axis movements to crush the ore, the crushing effect is poor, and secondary crushing is often required, improving the practicability of the device and the working efficiency of the user, and facilitating the use of the user.

[0005] When the above device performs multi-stage crushing on ore, due to the lack of a filtering component in ore crushing, some large particles of ore that are not completely crushed directly discharge from the discharge port, reducing the crushing effect and practicability of the device. To improve the crushing effect and practicability of the multi-stage ore crushing device, we propose a multi-stage ore crushing device. Content of the Utility Model
