生活垃圾中往往含有一定的废金属，废金属再生的生产工艺相对简单，流程短，工序少，有害杂质少。如果分类回收搞得好，许多废金属均可直接利用，几乎没有污染，还可节约投资，降低成本，提高经济效益。如我国生产1t再生铝与生产1t原生铝相比，可以节约投资87.5%，降低生产费用40%--58%。因此，生活垃圾中的这些废杂金属应尽可能地从垃圾中分离出来，回收再利用， 更多精彩内容，请关注重庆废铜回收网站：http://www.cqfphsgs.net
Domestic waste often contains a certain amount of scrap metal,scrap metal regeneration of the production process is relatively simple,short process,less work,less harmful impurities.If the classification and recycling well,many scrap metal can be used directly,almost no pollution,but also can save investment,reduce costs,improve economic efficiency.Such as the production of 1t recycled aluminum and the production of 1t compared to the original aluminum,can save investment 87.5%,reduce production costs 40%--58%.As a result,these waste metals in domestic waste should be separated from waste as much as possible,
在城市垃圾、工业废物、废渣和冶炼炉副产品、污泥以及焚烧炉中有回收价值的黑色和有色金属，在大多数情况下，往往呈现成分变化很大的混合物形式。因为黑色金属用磁选法很容易分离，因首先考虑其分选出。黑色金属回收系统通常要用破碎机对金属进行破碎，然后将这种废物分成轻重部分。重的部分在一磁性传送带上进行分离，利用压块机将废物成块，然后再在一磁鼓上将黑色金属与有色金属分开。在工业上，也可在废物产生地点用目视法和磁选法把黑色金属和有色金属分开并装入各自的料斗。这将使用废物具有更大的价值，因为后面的处理重减少了。
In the city garbage,industrial waste,waste and by-products,smelting furnace and incinerator sludge recycling value in ferrous and non-ferrous metals,in most cases,often showing a mixture of form composition changes greatly.Because black metal is easy to separate by magnetic separation,because of the first to consider its separation.The black metal recovery system usually breaks the metal with a crusher,and then divides it into parts.The separation of parts in a magnetic conveyor belt,the press will waste into blocks,and then separated in a drum,black metal and non-ferrous metal.In the industry,it is also possible to separate ferrous and non-ferrous metals into their respective hoppers at the site of waste production by visual and magnetic separation.This will be of greater value for waste disposal,since the subsequent treatment is reduced.
金属分离综合流程，已成功应用于回收金属合金和黄铜、青铜、铜、铅、锌、铁、银、金、锡、碳化、硅和磨料等有用材料的综合处理。
Metal separation process has been successfully applied to the recovery of metal alloy and brass,bronze,copper,lead,zinc,iron,silver,gold,tin,silicon carbide,silicon and abrasive materials such as comprehensive treatment.
在金属回收系统中，废物先进入颚式破碎机的给料端检出，或放入冲击式破碎机。从破碎机出来的物料进入磨碎机粉碎至最终尺寸，并清除其废金属废物。磨碎一般在球磨机中进行。球磨机的产品再通过一台螺旋筛选机过筛分级，螺旋筛选机直接连在球磨机上，与球磨机一起旋转。产品尺寸一般在0.48-0.64cm的范围内。这就是最后的高级金属产品，不再需要进一步处理。然而螺旋筛选机筛出的粗产品如果含有较多杂质，还要在跳汰机上去除杂质，纯净的金属产品通过跳汰机侧面出口排出。由跳汰机端不排除的废物，如果尺寸过大，可以返送至磨碎工段。跳汰燥作是一种湿式分级方法，其目的是回收那些在筛选和分级燥作中没有被回收的细粒产品。
In the metal recovery system,the waste is advanced to the feed end of the jaw crusher,or into the impact crusher.The material from the crusher enters the grinding machine to crush to the final size,and the waste metal waste is removed.Grind generally in ball mill.The product of the ball mill is sieved through a spiral screening machine,the spiral screening machine is directly connected with the ball mill,and is rotated together with the ball mill.Product size is generally in the range of 0.48-0.64cm.This is the end of the advanced metal products,no further processing.However,if the screening of the crude product of the spiral screening machine contains more impurities,it also removes impurities on the jig,and the pure metal products are discharged through the side of the jig.From the end of the jig does not exclude waste,if the size is too large,can be returned to the grinding section.Jigging is a wet classification method,which is aimed at the recovery of fine particles that have not been recovered during screening and grading. 更多精彩内容，请关注重庆废铜回收网站：http://www.cqfphsgs.net
由跳汰机排出的细料用一台或几台摇床进行处理。可回收的金属量通常很小，如果有尺寸较大的颗粒，可用将其送回分级机，在某些情况下可送回原料堆。
The fine material discharged from the jig is handled by one or more tables.The recoverable amount of the metal is usually small,and if there are larger particles,it can be sent back to the classifier and,in some cases,can be returned to the reactor.、
