Double Spiral Ore Washer – High Efficiency Mineral Washing Equipment
It is a high-efficiency mineral washing and classifying equipment for coarse and medium grains based on gravity sedimentation and hydraulic classification.
With double spiral symmetric layout, it can complete desliming, classification, washing and dehydration in one operation.
Suitable for large-scale operations, especially for refractory ores with high mud content, and widely used in mining, metallurgy and other industries.
The double spiral ore washer is a high-efficiency medium and large-sized coarse and medium-grain mineral washing and classifying equipment based on the principles of gravity sedimentation and hydraulic classification. It adopts a core design of double spiral symmetric layout + high weir type trough. Through the synchronous reverse rotation of two spiral blades, it drives the materials to fully tumble and scrub, and completes multiple operations of desliming, classification, washing and dehydration synchronously. It is divided into four specifications: industrial small, industrial medium, industrial large and mobile. The equipment has the advantages of firm structure, high efficiency of double shaft synchronization, wear resistance and energy saving, intelligent control, strong adaptability, accurate classification, safety and environmental protection. Different from the single spiral ore washer, it has higher processing efficiency and more uniform scrubbing, focusing on medium and large-scale operations. It can process a variety of coarse and medium-grain muddy ores, especially suitable for refractory ores with high mud content. It is easy to operate and low in maintenance cost. It can not only complete the ore washing and classification operation independently, but also form a complete mineral processing production line with crushing, grinding and sorting equipment. It is widely used in mining, metallurgy, building materials, environmental protection and other industries. It is an efficient preferred equipment for washing and classifying medium and large-sized coarse and medium-grain minerals, which can effectively improve the efficiency of subsequent operations and the grade of finished products, reduce resource waste and lower the comprehensive operation cost.
