为什么要回收废金属废料？

The scrap metal wastes recycling is of great significance. It can not only achieve resource reuse, save metal mineral resources, but also avoid environmental pollution. Recycling and reusing metal wastes is a good thing that benefits the country and the people. The commonly used metal resources recycling equipment is the hydraulic metal baler machine.

The brief definition of the waste metal scraps

废金属是指工业和金属加工业中废弃的金属碎片和碎片，以及机械设备更换时产生的金属外壳和碎片。此外，还有从城市垃圾和废车壳等金属材料中回收的金属。

工业金属有两种来源：一是金属矿石。另一个是废金属资源。金属矿石是一种自然资源，废金属是一种可回收的可再生资源。如果工业上多使用废金属，少使用金属矿石，将大大有助于节约金属矿产资源，同时也减少废金属对环境的污染，起到改善环境的作用。

What should we do before baling the metal scraps by metal baler?

废金属是一种重要的资源，各国都有专门的单位对废金属进行回收利用。回收的废金属主要用于精炼，然后转化为再生金属资源。少量废金属可用于生产机械、设备零件和各种工具。

In China, with the implementation of the circular economy strategy, the recycling of scrap metal will also become an important part of industrial development. However, to achieve this, sufficient scrap metal resources are required. So recycling scrap metal is very important. After the scrap metal is recycled, it contains a lot of renewable resources. Therefore, before the general waste metal is packed with a metal baler machine, the waste metal needs to be detected and classified accordingly, so that the waste metal resources can be more effectively recovered.

Current status of scrap metal recycling

近年来，在欧洲各国掀起了废金属资源利用的热潮，并收到了良好的环境、社会和经济效益。目前，世界各国废旧金属资源的实际情况差异很大。例如，美国拥有充足的废金属资源，可以大力发展再生金属加工业。可见，废金属资源也决定了一个国家冶炼行业的整体结构。
