The desliming cone, also known as a slime separation cone, operates on the principle of gravity sedimentation. Its main body features an inverted conical structure and consists of a central feed well, an overflow launder, and an underflow discharge orifice.
After the slurry is fed tangentially, coarse particles settle to the cone bottom and are discharged, while fine particles are separated via the overflow. The classification precision can reach below 75μm. Being entirely gravity-driven (power-free), this equipment combines desliming, thickening, and ore storage functions. It is highly economical and efficient, making it widely used in the pretreatment of minerals such as quartz sand.
This equipment is widely used in the preliminary stages of mineral processing. It is ideal for removing clay impurities from non-metallic minerals such as quartz sand and phosphate rock. Additionally, it can be used to thicken the slurry before grinding, while simultaneously regulating the pulp density and feed rate. This ensures the stable operation of downstream flotation and gravity separation equipment, effectively improving overall separation efficiency and reducing production energy consumption.
