title Briquetting>Process

The briquetting units shape fine materials into larger forms of varied shapes, sizes and volumes (from a few cc up to 600 cc and more) : these characteristics are defined according to the product end use.

If the cohesive forces (particulate cohesion, valence forces, recrystallization, van Der Waals forces…) between the particles are low, a binder has to be used before agglomeration. The physical properties of the feed material, the end use of the briquettes and the cost of binder addition have to be taken into account before a selection is made. A large variety of (liquid or solid) binders is offered: starch, bentonite, bitumen, lime, cement, water, flour, lignosulphonates, molasses, polymer, resin, sodium silicate, etc…

The briquettes are obtained at a low or high pressure and can undergo mechanical or thermal treatment according to the characteristics of the processed material, the binder used and the desired end product. Considering the large variety of products to be processed and the binders used, the range of mixers designed and proposed by SAHUT-CONREUR is specifically adapted to each type of briquetting:

puce Vertical mixers or pug mills, for instance for briquetting of coal with bitumen.

puce Twin screw mixers, for instance for briquetting of some chemicals with water ; these mixers can be equipped with heating or cooling jacket, as the case may be.

puce Horizontal or ploughshare mixers, for instance for briquetting of some minerals with molasses ; these mixers can also be equipped with heating or cooling jacket, as the case may be.

briquetting process


According to the material, the main stages of the process can be as follows:
puce Product preparation unit (screening-crushing, drying, sieving)
puce Dosing and mixing of product with binder
puce Briquetting unit
puce Post treatment of the briquettes (air or oven drying, curing, polymerization, aging)

briquetting process

The capacity of a briquetting line can range from 50 kg/h to 100 T/h and for products with a temperature range between -40°C and + 1000°C.
