In the fields of mineral processing, metallurgical processing, and non-metallic mineral purification, high-weir single-screw and double-screw classifiers serve as core equipment for material particle size classification. Based on the same gravity sedimentation principle, the two types of equipment feature distinct application orientations due to structural differences, accurately meeting the production needs of different scales.
The high-weir single-screw classifier has a simplified structure, driven by a single screw shaft. It boasts a compact size, small footprint, simple operation and maintenance procedures, and low failure rate. Its core advantages lie in cost-effectiveness and flexibility. It is suitable for small and medium-sized production lines, and can form a closed-circuit circulation system with ball mills to complete basic processes such as ore sand classification and ore washing & desliming. It delivers high cost performance in production scenarios with limited budgets and compact spaces.
The high-weir double-screw classifier adopts a parallel and reverse operation design with dual screw shafts. It has a larger effective sedimentation area of the tank body, and its material processing efficiency can reach 1.5 to 2 times that of single-screw equipment of the same specification. The synergistic effect of the dual screws ensures more uniform pulp mixing and higher classification accuracy, which can reduce the entrainment of coarse and fine particles. This equipment is more suitable for large-scale concentrators and high-capacity classification scenarios, which can reduce the load of subsequent equipment and improve the overall production stability.
From cost-controllable small and medium-sized operations to efficient and precise large-scale production, high-weir single-screw and double-screw classifiers have become reliable choices for the material classification process in various industries with their practical performance advantages.
