Scrap Processing : Making Metal Recycling more efficient and profitable
What is scrap processing? – The steps involved in managing and transporting scrap efficiently before actual melting are referred to as Scrap processing. At Advance Hydrau-tech, we have termed scrap processing as Cold Refining.
Thus, Cold Refining means making the scrap purer and more dense using cold processes, i.e., processes that do not involve any heat or fire. Any method of scrap processing will involve mainly 3 steps namely Sorting, Cleaning and Densification which are the major components of any refining process.
1. Sorting: involves segregating different varieties of scrap
2. Then comes Cleaning, which means removing the unwanted or foreign material. For example, removing the rust and dust thereby increasing the purity of the material
3. Finally Densification which means to increase the density of material that will finally go for melting
Following these three steps of Cold Refining will always be less expensive and less capital intensive as compared to doing only hot refining or melting which is being followed in general. Hence, Scrap processing is important because processed scrap can help increase the revenues –
for processor in terms of achieving more weight, lesser storage area, benefits of sorting different types of scrap material, ease of transportation and hence lesser cost and many more.
And, for the end user i.e. the melting units, by way of better yields because of cleaner material, and more production because of less charging and melting time due to denser material. Therefore, scrap processing holds a very important place in the entire scrap based industry.
Therefore, all scrap processing machines should focus on the 3 steps of Cold Refining and can be achieved by one of the following 4 processes – Baling, Shearing, Shredding, and Briquetting
