The fines are pressed into the briquette shape. On occasion, it is desirable to use a binder in order to achieve various product characteristics. It is also worth noting that when a binder is not used, the machine must work harder, therefore reducing its capacity. Coal is an integral component in providing a growing, global demand for energy ...

Coal briquetting consists in applying pressure to small coal particles with or without the addition of a binder to form compact or agglomerateshaped fuels for domestic or industrial applications. This well tried and established technology was introduced by William Easby who, in 1848, patented a method to convert coal fines into solid lumps [1 ...

As a result, applying very high compressive forces typically causes fine particles to deform and agglomerate into a solid mass rather than being broken into finer particles. This has been the basis of coal briquetting processes for converting coal fines into more easily handled briquettes (Borowski Hycnar, 2013). In briquetting rolls, a pair ...
