2025 Best 10 Circular Stacker Factory in the world

Nov 12, 2025

Introduction to Circular Stacker

A circular stacker is a crucial piece of equipment in bulk material handling systems, commonly used in industries such as mining, power generation, cement production, and port logistics. It is designed to stack bulk materials, such as coal, ore, and grains, in a circular pattern. The circular stacker typically consists of a central column, a boom conveyor, a slewing mechanism, and a luffing mechanism. It can rotate around the central column and adjust the height and angle of the boom conveyor to stack materials evenly and efficiently. The use of circular stackers can improve the storage capacity of bulk materials, reduce the labor intensity of material handling, and improve the overall efficiency of the production process.
