巖金礦制沙選金、選沙方案分析

最近很多客戶在詢問巖金礦如何做到制沙、采金兼收，因為巖金礦選金本身就需要做到破碎完成后才能分離出金，巖金礦制沙也需要破碎后才可以完成制沙；在破碎完成后，如何兼收同時得到含金精礦又得到干凈的沙子用于建筑行業呢？本問就以下制沙選金、制沙兩個方案進行討論。

設備簡介

本套選金設備為固定式滾筒篩+離心機組合式破碎選金設備，處理量為每小時30-60噸，是我公司根據用戶需求獨立研發制作而成。本套設備運行穩定、故障率低，是當今主流的選金設備，深受國內外用戶的歡迎，其優勢如下：

1、滾筒篩供水系統采用中央供水+兩側供水，中央供水系統負責沖洗滾筒篩內物料，兩側供水系統負責沖洗外部細篩網，防止堵料。

2、本套設備技術成熟，故障率低，保養、維護簡單方便。

3、采用一臺1200#臥式全自動連續排礦離心機，PLC電腦全自動控制無需地面硬化與尋找水平，處理量大，操作簡單方便。

4、采用2臺振動溜槽進行收尾，防止收金草板結、處理量大。

Brief Introduction

This set of gold machine including reamers trommel screen,centrifuge and crushing gold equipment, the capacity of 30-60 t/h, which is our company according to user’s requirements design&manufactured. This set of equipment with easy operation, low failure rate, is the favourite in the market.The advantage as belows:

1.Central water supply system of Reamers&Trommel Screen Separator is on central and trommel’s both sides.The central is used for material washing, both sides is responsible for washing the mesh to prevent clogging.

2.As the technology is mature, machine with lower failure rate, simple operation and convenient maintenance

3.1200# horizontal automatic discharge with no break centrifuge, PLC control without need of seeking balance on ground, simple and convenient operation

4.The 2sets gold shaking sluice with high capacity can prevent the gold grass to be hardening

流程概述

原料通過工程機械送入進料斗，然后通過振動給料機均勻進入一臺鄂式破碎機內進行破碎，破碎后的物料通過一臺上料輸送機進入多鉸刀鉸洗筒內進行鉸泥沖洗，然后進入滾筒篩內進行篩選分級為大于4MM物料與小于4MM物料兩種規格。小于4MM的物料通過滑槽及管道進入盛料箱中；大于4MM的物料進入兩臺巖金礦專用制沙機內進行破碎制沙后進入盛料箱內。

盛料箱內的物料通過沙泵打入離心機內部進行精選，精料通過精料管道排出；廢料排入兩臺振動溜槽進行收尾后，廢料排入廢料池中。

Technological Process

The raw material getting into the hopper by excavator or other, then through the shaking feeder getting into jaw-type crusher to be crushed,the mixture through conveyor into reamers and trommel screen gold separating machine to be separated into 2 sizes,≧4mm≤4mm.The samll size≤4mm getting into mineral box though mineral separating device;the big size≧4mm getting into Sandmaking machine specialized for rockmine to be crushed then into mineral box.

Mineral in mineral box then getting into 100#centrifuge by sand pump to be separating,concentrate get from concentrate discharging port,scrap material into 2sets of gold shaking sluice for further separation,finally the scrap into waste pool.

案例二：

巖金礦制沙設備

流程概述

原料通過工程機械送入進料斗中，由振動給料機均勻送入一臺粗鄂式破碎機內進行破碎，破碎出的粗料由輸送機送入一臺反擊式制沙機進行破碎制沙，然后由輸送機送入滾筒篩內進行篩選分級為：5mm以下細料與大于5mm粗料兩種規格；

大于5mm的粗料由輸送機再次送入另一臺反擊式制沙機內進行破碎，然后通過回傳輸送機送入滾筒篩內繼續進行篩分，這一過程往復循環；

小于5mm的細料排入兩臺輪式洗沙機內進行清洗，清洗后的細沙通過一臺脫水篩進行脫水，最后由成品料輸送機輸送至成品料區域。

Technical process

The Raw material get into feed hopper then send by shaking feed into the jaw crusher to be crushed,the crushed material get into impact sand making machine I to make sand,then transport into trommel screen to be classified into 2size,≤5mm，≥5mm,

The one in size≥5mm will be transported by conveyor into another impact sand making machine to be crushed then get into trommel screen to be classified,

The one≤5mm will be send to bucket sand washing machine machine then into the dewater screen to get rid of water,then finally clean sand get and transported to destination area.
