Briquetting compresses dust or shavings – e.g. wood, plastics,
metals, paper – into round or square briquettes. Making briquettes
can considerably reduce the volume of the materials. This enables
better handling for storage and transportation, as well as
preventing a dust explosion risk. The material properties of the
briquettes that are produced are similar to those of the solid raw
material. This is why they are usually burned as an energy source or
recycled into new materials.
The hydraulic briquetting presses that are used in the briquetting
process apply considerable force to compress the material into
compact briquettes.
The material is fed in via a hopper that also functions as a
reservoir. Then it is supplied into the actual press cylinder via an
agitator, screw conveyors and pre-compressors. The cylinder volume
is filled and the material is compressed to produce briquettes of a
certain length. |
