Briquetting of metal waste

Moisture content of the material

Usually the material contains emulsions or oils, their presence is not an obstacle to briquetting. The briquetting process itself displaces a significant part of the liquids and therefore there is no need to remove the liquids in any way beforehand. In terms of residual moisture, briquetting is the most successful.

All displaced emulsions or oils can be reused.


Material size

Briquetting presses are designed to process waste with a normal size of up to 15 mm in one direction. If the material is loose, there is no need for crushing or a more complex hopper mechanism.

If the material is longer (up to approx. 30 cm) it is necessary that the briquetting press includes a hopper that can dispense the material.

In the case of material that forms compact clumps, it is necessary to crush the material. The crusher can also be implemented in the hopper of the press.


Crushing of the material

The size of the input material is decisive for the quality of the briquette and the performance of the press. Depending on the type of material, the presence of chunks, the minimum hopper size required and the required performance and the requirement for automation of the operation, we are able to supply the most suitable type of crusher from different manufacturers. We carry out free crushing tests for certain types of waste.


Mechanical contamination of the material

This means, for example, the presence of ferromagnetic particles in aluminium chips or the presence of lumps.

Depending on the characteristics of the material, we will find a solution for sorting these impurities.


Wear of pressing tools

Wear depends on the type of material and alloy, its hardness and the mechanical properties of the chips themselves. A briquetting press can process anything from abrasive sludge to stainless steel to soft metals such as aluminium. Tool life ranges from hundreds of hours (sludge) to thousands of hours.


Briquetting for better transport and landfill

Briquetting significantly reduces the volume of material, thus reducing handling, transport and logistics requirements in general. By turning loose chips into solid material (briquettes), the cleanliness of the working environment is increased.


Use of briquettes

Metal briquettes are usually easier to melt. The chips float on the surface and burn easily due to their huge surface area. Briquettes made of chips sink more easily and have less metal burnouts. In addition, they are free of oils and emulsions that can be reused in production and are undesirable in smelting.
