TECHNICAL FIELD

[0001] The utility model relates to the technical field of waste metal recycling, in particular to a waste metal classification device after fine crushing. BACKGROUND

[0002] Fine crushing and classification of waste metals are of great significance in the field of resource recycling, which can effectively reduce the exploitation of primary mineral resources, reduce environmental pollution, and achieve the goal of circular economy. Fine crushing is to crush the recycled metal materials such as waste household appliances, automobile parts, and electric wires and cables through a crusher and other equipment, so as to separate large pieces of metal into smaller particles for subsequent sorting and purification. In this process, not only the environmental burden caused by waste metal landfill or incineration is reduced, but also high-quality recycled materials can be provided for industrial production through secondary processing, promoting sustainable development.

[0003] In the fine crushing and classification of waste metals, due to the variety of waste metals, density, shape, and magnetism, the existing waste metal processing device cannot achieve efficient and rapid classification of these metals. Traditional devices usually rely on single magnetic separation or vibration screening method, which is difficult to effectively separate non-magnetic metals (such as aluminum and copper) and metal materials with small density difference. In addition, the uniform material mechanism is not uniform in processing, which leads to uneven material accumulation or spacing, further affecting the classification accuracy. SUMMARY

[0011] Based on the above technical features, the vibration material separation mechanism classifies the non-magnetic metal particles of different particle sizes through the sieve plate in the vibration box, and the material is uniformly distributed on the sieve plate and separated through the sieve holes by the action of the vibration motor. Different particle sizes of metal particles are respectively guided out of the sieve plate, the vibration box and the two material separation grooves in the vibration process according to the weight, so that metal particles of different particle sizes and weights can be accurately classified and collected, efficient and stable automatic separation is realized, and the separation quality and efficiency of the whole device are improved.
