Metal shavings: save resources with briquetting systems
Briquetting presses lay the foundation for the recycling of metal chips in the metallurgical cycle. In the spirit of a closed recycling strategy.
Recycling of metal waste is becoming more and more important. Resources are finite, and since prices, especially for metals, are highly volatile, countermeasures are important. This can be achieved using high quality briquetting presses from Ruf. Because it lays the foundation for the best recycling of metal chips in the metallurgical cycle, in line with a closed-loop recycling strategy. When metal fabricators remove their products from milling machines, lathes, grinders or saws, there is often very little material left of the original semi-finished product. The rest lies like chips in prefabricated containers. They are often covered with cutting fluid and have a residual moisture content of up to 15%, and in some cases even more. This needs to be changed. On the one hand, these are the requirements of the law. which prohibit the transportation of wet, untreated wood chips. On the other hand, recycling in this form at an attractive price is hardly possible.
But even dry shavings are poorly suited for remelting. Due to their low weight, they float in the weld pool, which leads to high combustion losses. A less robust approach that can be easily optimized. The key to this is to collect the chips by type as much as possible and then briquet them. Efficient briquetting presses from Ruf Maschinenbau GmbH & Co. are suitable for this. kg.
Chip moisture below 2%
With these systems, the moisture content of metal chips can be reduced to less than 2%, depending on the material. On the other hand, they always provide a high density of the briquette, close to the solid material. In numbers: in continuous operation, Ruf presses reach values of up to 6.9 kg/l for cast iron or up to 2.5 kg/l for aluminium. Briquetting systems operate at specific pressures up to 4000 kg/cm² for cast iron and 1700 or 3000 kg/cm² for aluminium, and reach capacities from 30 to 3000 kg/h.
And another important advantage that arises for manufacturing companies when using presses: in particular, large chips take up a lot of space and often have to be removed. This makes logistics difficult and expensive, and valuable space and storage and transportation costs are wasted. Due to the drastic volume reduction during briquetting, a lot of space is achieved. This is an advantage both for the internal logistics of forklifts and for the external one, when the briquettes are transported by trucks for processing. Financial costs and energy consumption are reduced equally - in the spirit of resource-saving and sustainable management.
