Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of alloy production devices, in particular to a crushing device for smelting large-particle alloys. BACKGROUND

[0002] In the metallurgical industry, the demand for large-particle alloys is increasing, especially in high-tech fields such as aerospace, automobile manufacturing, and electronic equipment. Large-particle alloys have excellent physical and chemical properties, but during the smelting process, how to effectively crush raw materials to achieve the appropriate particle size and uniformity becomes an important factor restricting the production efficiency and quality of alloys. Compared with traditional crushers, multi-tooth roller crushers have higher crushing efficiency. Their unique working principle and tooth shape design can more effectively crush materials to the desired particle size.

[0003] However, the existing multi-tooth roller crusher directly contacts the high-speed rotating tooth roller with the large-particle material during feeding, causing the particles to scatter everywhere. Not only can this pose a safety threat to the operator, especially without wearing appropriate protective equipment, but it can also easily cause accidental injuries such as eye injuries and skin scratches. Moreover, the direct contact between the high-speed rotating tooth roller and the material can cause additional wear on the surface of the tooth roller, accelerating equipment wear, increasing maintenance costs, and increasing replacement frequency. Although existing technologies have taken some preventive and improvement measures, such as installing protective covers or partitions, the added protective devices increase the difficulty of feeding. Therefore, it is necessary to provide a crushing device that meets the conditions for sealed feeding while maintaining normal feeding speed. SUMMARY
