AI Technical Summary
Existing bauxite gradient composite material lamination sintering equipment suffers from low feeding efficiency and micropore defects caused by material agglomeration, making it difficult for existing equipment to achieve efficient layering and uniform densification.
The design combines a vibration separation zone and a flat conveyor belt within the hopper. The vibration separation zone enables automatic stratification of materials, and the cam drives the vibration separation zone to perform stratification. Combined with the vertical micro-vibration and synchronous rotation of the flat conveyor belt, agglomerates are eliminated, achieving automatic feeding of a three-stage gradation structure. Multi-stage sintering is then carried out through a variable-temperature tunnel kiln.
This technology enables efficient and automated layered feeding of bauxite gradient composite materials, eliminating micropore defects, improving green density and feeding efficiency, and ensuring uniform densification and interfacial bonding during the sintering process.
