AI Technical Summary
Traditional spiral chute has a space efficiency bottleneck. The single-layer planar layout limits the processing capacity of the equipment, resulting in a large footprint and low plant space utilization, which is particularly evident in intensive and large-scale mineral processing plants.
Multiple sets of chute components are used, each set containing multiple staggered spiral grooves. Combined with a uniform hopper, a receiving hopper, and a guide plate, multi-channel mineral beneficiation and screening are achieved. The coaxial staggered threads of the spiral grooves provide more sorting paths in three-dimensional space.
Without increasing the floor space footprint, it significantly improves the sorting efficiency and processing capacity per unit space, increases mineral processing efficiency and volume, and achieves more rational space utilization.
