The bridge-type multi-bucket excavator is an aging equipment that must be equipped for the production of high-grade bricks such as sintered blocks, and an aging and reclaiming equipment with high requirements for raw material aging. It can fully realize layered fabrics and vertical cutting of materials in cross-section, ensuring the best aging effect of raw materials, the best particle gradation, the best raw material mixing and homogenization, and the best raw material humidity homogenization, thereby greatly improving the quality of sintered finished products. It is the most advanced and popular aging method in the world today.

The technical R & D personnel of Zibo Jieda Machinery Co., Ltd. went to Europe to study, introduce and digest foreign technologies, and realize a state-of-the-art raw material aging equipment for localized R & D and production. In 2014, it obtained the "Utility Model Patent Certificate" issued by the State Intellectual Property Administration (patent number: ZL201320658505.8). Its main feature is that a fixed frame body and an excavator boom are fixed and installed above the aging warehouse. The excavator boom and the lower part are inclined downward, and the excavator boom is driven by a walking drive device to reciprocate horizontally along the upper top surface of the fixed frame body. Moving, the lower part of the fixed frame body is provided with an output belt conveyor for material outward conveying. The bridge-type multi-bucket excavator changes the installation position of the excavator equipment, makes full use of the effective space of the aging warehouse, effectively reduces the floor area of the equipment in the aging warehouse, reduces the civil construction cost, and simplifies the equipment structure and operation steps, while reducing noise and air pollution.
