Equipment for briquetting of moist and wet mixes of various bulk materials.Equipment for briquetting due to the high pressures in the cone compression chamber (about 2000 kg/см.кв.) allow to produce high-quality briquettes from a variety of bulk materials. The principle of action of euipment for briquetting is caused by the very principle of technological process of extrusion.
Extrusion is a multi-faceted physico-chemical process runs under the action of external mechanical force under condition of presence of moisture and high temperature impact. In the presses of the proposed design of the extrusion occurs without an external source of heat. The product is heated up due to the transformation of mechanical energy into heat which is the internal friction and the plastic deformation of the product at the time of compression. The offered equipment ensures the process of obtaining the briquette as without connecting additives, as well as with their using. To get a bricks made of material not having in its composition of natural binders use astringent technological additives.
When using connecting additives, at the time of briquetting, contained in them binders and concentrating on the surface of mechanical particles of the material make their grip and later (after cooling and drying), cause sufficient strength of the briquettes. In case if in the processing re included in the composition of the natural binding materials (brown wax, lignin, coal-tar pitch, etc.) as a result of extrusion go change similar to the first case, ensuring the high strength of the final product, without the use of additional binding additives. Thus, we manage to get without using binders quality briquettes from almost all types of coal, brown coal, peat, wood coal, various technological mineral mixtures, etc.
