Coal briquette binder (also known as coal binder, briquette adhesive, composite binder, etc.) is a binder that consolidates and strengthens powdered fuels like coal dust, facilitating molding into solid blocks; a powder or liquid auxiliary material for briquettes that ensures specific shape and performance after molding; primarily used in briquetting processes as an auxiliary. Coal briquette binder is a crucial auxiliary material determining the quality of coal briquettes.

Type coal binder is formed through complex chemical reactions involving inorganic substances and various organic chemical raw materials. When mixed with powdered coal, it rapidly forms a needle-like and mesh structure, thereby granting the molded coal (coal briquettes) high cold and hot mechanical strength and thermal stability; excellent moisture and water resistance, as well as immersion strength; high combustion value when placed in the furnace, with high thermal intensity post-combustion, low breakage rate upon falling, free of ash, non-polluting, and easy to operate.

Application Scope

1. Cold-pressed molding. The powdered coal binder is mixed thoroughly with the coal material, then pressed into shape on a briquette molding machine; the molding process is carried out at room temperature without the need for heating.

2. Pellet Formation: Mix the powdered coal with binder liquid thoroughly and evenly, then shape it into pellets using a disc pelletizer or a drum pelletizer.

Application Fields

Coal briquette composite binder is widely used in industries such as chemicals, fertilizers, glass, building materials, metallurgy, coal gas, and civil industries for producing civil or industrial fuel briquettes, coal gasification briquettes, and metallurgical briquettes (pellets). It can process waste materials, coal powder, and other by-products from coal mines and metallurgical industries into briquettes.
