Briquetting and recycling of scrap ferrous metals

The realities of today are such that the ecological purity of our environment requires constant attention and timely intervention so as not to harm it. One of the important activities that contribute to the preservation, conservation of natural resources, is the heavy machinery removal, of which a variety of products have been manufactured. That is why almost every city has enterprises, companies and organizations that specialize in receiving and processing scrap metal.

But not many of them can boast of equipment that allows taking scrap metal for its further processing, preparation for shipment to the metallurgical plant.

But for years, our citizen

s can accumulate unsorted scrap metal in the garage, cottage, basement, even on the balcony. We are talking about old bicycles, sleds, baby carriages, tin cans, jerrycans, refrigerators, car body parts and many other things that are eventually just thrown away. It is not uncommon when an audit of a garage or a country barn allows you to collect more than a hundred kilograms of scrap metal, for which you can get quite acceptable money.

The need for briquetting

All non-grade scrap metal is thin-walled, often highly corroded products, as well as waste metal (shavings, scraps of metal, etc.), which thus occupy a fairly large amount of space. If it is not compressed into a compact and fairly massive briquette, then:

It will take a lot of space to store at the scrap yard.
Transporting it would not be economically feasible. Practice shows that a truck or rail car will be filled to no more than 25-30% of their normal carrying capacity.
When it is delivered to the blast furnace for remelting, much of it will simply burn up from the high temperature.
To avoid this and to supply steel mills with high quality raw material for remelting, the following types of light scrap processing are currently used:

Shredding – considered to be the most modern technology for converting unsorted scrap into oversized, ready-to-feed raw material into the steelmaking plant.
Briquetting – used to press the chips into compact and massive briquettes, which are valued by steelmakers because of their high density.
Batching – using a special press to form bulky lightweight metal products (car bodies, washing machine and refrigerator casings, metal containers, nets, stroller and bicycle frames, tin cans, etc.) into equally sized briquettes. Such bagged scrap is convenient both for storage and transportation.
