Pangkalahatang -ideya ng produkto
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.
Ang prinsipyo ng pagtatrabaho
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".
Sa paayon na direksyon, ang pagkakaiba -iba ng paggalaw ng ibabaw ng kama, sa una sa isang mabagal na bilis at unti -unting mapabilis, sa maximum na bilis kapag ang biglaang pag -urong, ang bilis ay unti -unting bumababa sa panahon ng proseso ng pag -urong, at pagkatapos ay pasulong, ulitin ang proseso sa itaas, hindi lamang isusulong ang maluwag na stratification ng layer ng ore, ngunit din gawin ang mabibigat na mga partikulo ng ore na sumulong sa kahabaan ng paayon sa isang mas malaking bilis, sa gayon ang ilaw o mga particle particle ay sumulong sa isang mas maliit na bilis. Kung saan ang mga partikulo ng mineral ay nakasalalay sa kumbinasyon ng paayon na bilis at transverse na tulin. Ang mga mabibigat na mineral ay may mas maliit na transverse velocity at mas malaking paayon na tulin, at ang mga light mineral ay may mas malaking transverse velocity at mas maliit na paayon na tulin.
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.
Ang mga light mineral sa itaas na layer ng uka ay unang hinubad at inilipat sa gilid ng tailings kasama ang pahalang na direksyon ng ibabaw ng kama, at ang mabibigat na mineral ay pinalabas mula sa pagtatapos ng concentrate. Samakatuwid, ang mga mineral sa buong ibabaw ng kama ay nagpapakita ng pamamahagi ng tagahanga ayon sa iba't ibang gravity at iba't ibang laki ng butil, upang makakuha ng iba't ibang mga produkto.
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.
