Hydraulic classifier is a kind of granularity classifier. It has the advantages of high efficiency, low energy consumption and no noise. It is the equipment system in the field of mineral classification.
The basic structure of the hydraulic classifier is round, and the main body is composed of the upper cylinder and the lower cone. Fluidized bed and rising water technology are used to complete the high efficiency classification in the middle of the coarse-grained classification chamber and the circular fine-grained classification chamber around it. The pulp is supplied vertically from the middle of the coarse-grained classification chamber to the distribution plate at the bottom of the coarse-grained classification chamber through a special pipeline. Upwelling water enters the coarse-grained classification chamber through a circular gap between the distribution plate and the wall of the coarse-grained classification chamber, and forms turbulent zone at the lower part of the coarse-grained classification chamber to achieve coarse-grained classification. Coarse-grained minerals settle in accordance with technological requirements and enter the coarse-grained discharge outlet located at the middle of the bottom of the coarse-grained classification chamber through the circular gap mentioned above. Fine minerals enter the annular classification chamber by overflow.
Fine and ultrafine minerals are classified by fluidized bed technology in the fine classification chamber. Rising water is evenly divided at the bottom of the whole fine-grained classification chamber through a special screen installed at the bottom of the fine-grained classification chamber, which ensures the formation of a uniform and stable laminar fluidized bed to achieve accurate classification. Ultrafine minerals enter the annular overflow trough surrounding the fine-grained classification chamber side by side. Fine minerals settle at the bottom of the fine classification chamber and are discharged through a valve with annular distribution along the screen surface.
The opening, closing and discharging speed of all discharging valves in two classifying chambers of coarse and fine particles are controlled and adjusted by on-line measurement of pulp density. The particle size of coarse-grained, fine-grained and ultra-fine-grained products (i.e. sand settling in coarse-grained classifying chamber, sand settling in fine-grained classifying chamber and final overflow product of equipment) can be adjusted by changing the height of fluidized bed and the amount of rising water when the field fluid load is known. In addition, the concentration and flow distribution of the products can be adjusted within a certain range according to the process requirements.
According to the parameters of feed size, mineral specific gravity and pulp concentration, different and adjustable rising water volume is adopted, and the bottom sieve surface of fine-grained classification chamber with different structure is selected to adjust the pressure difference between the upper and lower sieve surface, so as to ensure the uniform fluidization and accurate classification of mineral particles.
