Descripción general del producto
The beneficiation process of the shaker is carried out on the inclined bed surface with repeated strips. The ore particles are sent from the feed trough at the corner of the bed surface, and the transverse washing water is supplied to the feed trough. Under the action of gravity, the transverse water impulse, the inertia and friction caused by the reciprocating asymmetric movement of the bed surface, the ore particles are stratified according to specific gravity and particle size. The longitudinal motion along the bed surface and the transverse motion along the inclined bed surface are made. Therefore, the ore particles with different specific gravity and particle size gradually fan down in their respective direction of movement, respectively from different areas of theconcentrate end and tailings side, and finally are divided into concentrate, ore and tailings.The outstanding advantage of 6-S shaker is that the separation accuracy is high, and the final concentrate, middle ore and waste tailings can be obtained after a single separation, and multiple products can be obtained at the same time. The concentration ratio of concentrate is high, the sorting efficiency is high, the care is easy, and the stroke is easy to adjust.
El principio de trabajo
Shaker sorting is realized under the joint action of bed shaking and transverse water flow. Bed bed strips are longitudinal and the direction of water flow is close to vertical. When water flow crosses each bed strip laterally, eddy currents are formed in the groove. The combined action of eddy currents and bed shaking can loosen the mineral sand layer and stratify it according to density. The upper light ore particles are subject to the greater impulse of the water flow, while the lower heavy ore particles are subject to the lesser impulse, so the transverse movement speed of the light ore particles on the bed is greater than that of the heavy ore particles on the bed. This process is called "de lamination".
En la dirección longitudinal, el movimiento diferencial de la superficie del lecho, al principio a una velocidad lenta y se acelera gradualmente, a la velocidad máxima cuando la retirada repentina, la velocidad disminuye gradualmente durante el proceso de retirada, y luego hacia adelante, repita el proceso anterior, no solo promueve la estratificación de la capa de mineral, sino que también se avanzan en las partículas más pequeñas a la longitud más pequeña. Donde van las partículas de mineral depende de la combinación de velocidad longitudinal y velocidad transversal. Los minerales pesados tienen una velocidad transversal más pequeña y una velocidad longitudinal más grande, y los minerales ligeros tienen una velocidad transversal mayor y una velocidad longitudinal más pequeña.
Applying the parallelogram rule to synthesize the longitudinal velocity and transverse velocity, it can be seen that the combined velocity of heavy minerals is inclined to the concentrate end of the shaker, light minerals are inclined to the tailings side of the shaker, and medium density particles are located between the two. This process is called "transport banding".Since the height of the bed is gradually reduced along the longitudinal direction of the self-driving end, the stratified ore particle groups in the groove are continuously stripped off during the movement to the concentrate end.
Los minerales ligeros en la capa superior del surco se despojan primero y se mueven hacia el lado de los relaves a lo largo de la dirección horizontal de la superficie del lecho, y los minerales pesados se descargan del extremo concentrado. Por lo tanto, los minerales en toda la superficie del lecho muestran una distribución del ventilador de acuerdo con una gravedad diferente y un tamaño de partícula diferente, para obtener una variedad de productos.
The concentrate strip is washed by transverse water flow in the smooth area of the bed surface (no bed strip area), so that a few gangue particles mixed in it are washed out, and the grade of the concentrate is further improved.
