Lub rooj kub shaker ua haujlwm li cas?
Lub rooj kub shaker (tseem hu ua lub ntiajteb txawj nqus co lub rooj) yog ib qho tseem ceeb ntawm lub ntiajteb txawj nqus sib cais cov cuab yeej siv dav hauv cov txiaj ntsig kub. Nws txoj haujlwm ua haujlwm yog nyob ntawm qhovKev sib xyaw ua ke ntawm lub ntiajteb txawj nqus, inertial quab yuam los ntawm lub rooj vibration, thiab dej ntws shear quab yuamcais cov khoom kub los ntawm gangue raws li qhov sib txawv ntawm lub cev (qhov ntom, qhov loj me, cov duab). Hauv qab no yog cov ncauj lus kom ntxaws txog nws txoj haujlwm ua haujlwm, cov khoom siv, thiab cov txheej txheem sib cais:
2. Cov ntsiab cai ua haujlwm tseem ceeb
Cov txheej txheem sib cais yog tsav los ntawm peb lub zog sib koom ua ke, uas ua txawv ntawm kub thiab gangue hais:
(1) Force Analysis ntawm Particle
Lub ntiajteb txawj nqus (G): Pulls hais downwards, nrog siab dua -density kub (density: 19.3 g/cm³) muaj zog gravitational ntau dua li qis-density gangue (xws li, quartz: 2.65 g/cm³).
Vibrational Inertial quab yuam (Fv): Tsim los ntawm lub rooj sib txuas ntawm kev co (forward stroke: muaj zog thawb; rov qab stroke: tsis muaj zog rub), propels hais raws li lub rooj ntev.
Dej Flow Shear Force (Fw): Nyias dej zaj duab xis (ntws tus nqi: 0.5-2 L / min ib cm ntawm lub rooj dav) ntawm lub lawj exerts lateral shear force, ntxuav lub sib zog hais sideways.
(2) Separation Mechanism: "Layer + Transport"
Stratification los ntawm ntom: Thaum cov pulp yog pub rau ntawm lub rooj inclined, hnyav dua cov khoom kub tog rau hauv qab ntawm cov yeeb yaj kiab dej (hu rau lub rooj lawj) vim muaj zog lub ntiajteb txawj nqus, thaum sib dua gangue ntab rau hauv cov dej sab saud. Lub grooved lawj txhim kho stratification los ntawm kev ntxiab cov khoom hnyav hauv cov grooves.
Differential thauj los ntawm kev vibration & dej ntws:
Longitudinal Transport (Kub): Lub rooj rau pem hauv ntej kev co (muaj zog quab yuam) thawb cov khoom kub (hauv qab) raws lub lawj ntev mus rauconcentrate chute(ze ntawm lub rooj hauv qab kawg). Kev vibration rov qab (tsis muaj zog) muaj kev cuam tshuam me ntsis rau cov khoom hnyav.
Lateral Thauj (Gangue): Cov khoom sib dua gangue (floating nyob rau hauv cov yeeb yaj kiab dej) raug ntxuav sab nraud los ntawm cov dej ntws mus rautailings chute(ntawm lub rooj sab siab).
Middlings: Cov khoom uas muaj qhov nruab nrab ntom ntom (piv txwv li, sib xyaw kub-gangue) raug thauj mus rau qhov nruab nrab chute, uas tuaj yeem rov ua dua kom rov zoo dua.
(3) Kev hloov kho tseem ceeb rau kev ua kom zoo
Vibration zaus / Amplitude: Ntau zaus (800–1200 strokes/min) suits zoo kub (0.074–0.3mm); qis zaus (400-600 strokes / min) rau coarse kub (0.3-2mm).
Rooj Inclination: Nce sab qaij txhim khu cov dej ntws (kev tshem tawm gangue zoo dua); kho pem hauv ntej-rov qab qaij tswj qhov ceev ntawm kev thauj kub.
Dej Flow Rate: Cov dej ntau dhau ntxuav cov kub zoo; tsawg dhau tsis tshem tawm gangue.
Feed Rate/Concentration: Stable feed (1–5 t/h ib lub rooj) thiab pulp concentration (25–30%) xyuas kom meej stratification uniform.
3. Cov ntawv thov zoo sib xws rau cov lus kub Shaker
Kub Ore Beneficiation: Qhov zoo tshaj plaws rau kev rov qab dawb kub (kub haiv neeg) los ntawm placer kub (alluvial kub) los yog crushed hard pob zeb kub ore (tom qab sib tsoo rau 0.074–2mm).
Gravity Concentration Stage: Feem ntau siv tom qab jigs lossis spirals los txhim kho kev mloog zoo (qib kub tuaj yeem nce los ntawm 5-10 g / t mus rau 50-100 g / t) los yog ua ib qho scavenger kom rov qab zoo kub poob hauv tailings.
High-Purity Gold Production: tuaj yeem siv rau hauv ntau- theem sib cais (roughing → tu → scavenging) kom ua tiav cov nyiaj rov qab kub ntawm 90-95% dawb kub.
