بررسی اجمالی محصول
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.
اصل کار
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".
در جهت طولی ، حرکت دیفرانسیل سطح بستر ، در ابتدا با سرعت آهسته و به تدریج تسریع می شود ، تا حداکثر سرعت هنگام عقب نشینی ناگهانی ، سرعت به تدریج در طی فرآیند عقب نشینی کاهش می یابد ، و سپس روند فوق را تکرار می کند ، نه تنها باعث ترویج طبقه بندی شده لایه سنگ معدن می شود ، بلکه ذرات سنگ معدن سنگین را حرکت می دهند که در امتداد سرعت حرکت به جلو حرکت می کنند و در طول طول عمر با سرعت بزرگتر حرکت می کنند. جایی که ذرات سنگ معدن به ترکیبی از سرعت طولی و سرعت عرضی بستگی دارد. مواد معدنی سنگین دارای سرعت عرضی کوچکتر و سرعت طولی بزرگتر هستند و مواد معدنی سبک دارای سرعت عرضی بزرگتر و سرعت طولی کوچکتر هستند.
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.
مواد معدنی سبک در لایه فوقانی شیار ابتدا از بین می روند و به سمت دکوراسیون در امتداد جهت افقی سطح بستر منتقل می شوند و مواد معدنی سنگین از انتهای کنسانتره تخلیه می شوند. بنابراین ، مواد معدنی موجود در کل سطح بستر ، توزیع فن را با توجه به گرانش متفاوت و اندازه ذرات مختلف نشان می دهد ، تا انواع مختلفی از محصولات را بدست آورند.
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.
