This post was last edited by songyan2310 on 2010-10-10 at 10:43. Some sources state that it is difficult to shape aged lignite without binders; for example, the lignite from Xilin Gol. Does this mean that binders must be used for the lignite from Xilin Gol? Does anyone know where I can find binders for lignite shaping? Those who are working on this project can also send an email to songyan2310@163.com, or get in touch with me via QQ at 1420428232
No one is responding; I’ll reply myself
Generally, the binders used for shaping lignite must be determined through testing. I’ve heard from others that a relatively economical and environmentally friendly binder can be the syrup produced by sugar factories.
Shaping lignite is too difficult; it’s not easy at all
Briquette coal, simply put, is coal in a defined shape; it is a coal product that is produced by further processing raw coal using modern methods, giving it a specific shape as well as certain physical and chemical properties. It is not, as people subjectively assume, simply a form of coal that can be called briquette after undergoing basic processing. In fact, briquettes that meet the standards require raw coal to be crushed first, or coal powder and slime as well as coke powder to be screened; thereafter, additives and binders are added in certain proportions, and after mixing, the mixture is processed using molding machinery to produce honeycomb briquettes, coal balls, and coal bricks. In this process, additives and binders are the key to the technology; it can be said that the entire technological content of briquettes lies in them. An excessive or insufficient amount of these substances will directly affect the combustion value of the briquettes, preventing them from meeting the required standards.
