Une goulotte en spirale est le meilleur \u00e9quipement de concentration, particuli\u00e8rement pour la concentration de minerai sableux en bord de mer et de rivi\u00e8re. Elle est fabriqu\u00e9e en fibre de verre rev\u00eatue de polyur\u00e9thane r\u00e9sistant \u00e0 l'usure et d'un recouvrement en corindon. <\/p>\n\n\n\n

Ses avantages sont la l\u00e9g\u00e8ret\u00e9, l'\u00e9tanch\u00e9it\u00e9, la r\u00e9sistance \u00e0 la rouille, \u00e0 la corrosion et l'absence de bruit, convenant parfaitement \u00e0 diff\u00e9rentes tailles et grades de particules d'alimentation. Cette machine de s\u00e9paration est un s\u00e9parateur gravim\u00e9trique \u00e0 spirale. <\/p>\n\n\n\n

La pulpe produit une force centrifuge inertielle lors du mouvement rotatif, et avec l'aide de la gravit\u00e9 simultan\u00e9ment, cela favorise la zonation des min\u00e9raux l\u00e9gers et lourds dans la goulotte en spirale, et leur \u00e9vacuation continue respective.<\/p>\n\n\n\n

Caract\u00e9ristiques de la goulotte en spirale<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

1. Structure raisonnable et faible encombrement.<\/p>\n\n\n\n

2. R\u00e9cup\u00e9ration \u00e9lev\u00e9e, haute efficacit\u00e9 et s\u00e9paration pr\u00e9cise.<\/p>\n\n\n\n

3. Aucune alimentation en \u00e9nergie requise.<\/p>\n\n\n\n

4. L\u00e9ger, anti-corrosion, r\u00e9sistant \u00e0 la rouille et \u00e0 l'usure.<\/p>\n\n\n\n

5. Installation simple et besoins de maintenance minimaux.<\/p>\n\n\n\n

6. Co\u00fbt d'exploitation faible et longue dur\u00e9e de vie.<\/p>\n\n\n\n

7. Fonctionnement fiable n\u00e9cessitant une attention minimale de l'op\u00e9rateur.<\/p>\n\n\n\n

8. Forte adaptabilit\u00e9 aux fluctuations du d\u00e9bit d'alimentation, de la densit\u00e9, de la taille et du grade.<\/p>\n\n\n\n

9. La surface du corindon cr\u00e9e une forte friction ; l'effet de concentration surpasse celui d'une surface en plastique.<\/p>\n\n\n

Principe de fonctionnement de la goulotte en spirale<\/h2>\n\n\n\n

\u00c9levez la goulotte en spirale et fixez-la en position appropri\u00e9e, la pompe \u00e0 sable transporte le minerai vers l'orifice d'alimentation, en ajoutant de l'eau pour ajuster la concentration de la pulpe. La pulpe tourbillonne naturellement de haut en bas et g\u00e9n\u00e8re une force centrifuge inertielle dans la vitesse d'\u00e9coulement inclin\u00e9 rotatif. Le minerai est s\u00e9par\u00e9 du sable par la gravit\u00e9 et la force centrifuge du tourbillon, selon la diff\u00e9rence de densit\u00e9 sp\u00e9cifique, de granulom\u00e9trie et de forme du minerai. Le concentr\u00e9 s'\u00e9coule dans la tr\u00e9mie \u00e0 concentr\u00e9 et est \u00e9vacu\u00e9 par la canalisation. Les r\u00e9sidus (sables st\u00e9riles) s'\u00e9coulent dans la tr\u00e9mie \u00e0 st\u00e9riles et sont achemin\u00e9s vers le bassin \u00e0 sable par la canalisation, puis \u00e9vacu\u00e9s par la pompe \u00e0 sable pour compl\u00e9ter l'ensemble du processus de valorisation.<\/p>\n\n\n
