Coal briquette binder (also known as coal agglomeration agent, coal bonding agent, coal adhesive, and composite coal bonding agent, etc.) is a binder that consolidates and strengthens powdered fuels like coal dust, facilitating the molding into solid blocks; it ensures the briquettes have specific shapes and properties. It is a powdered or liquid auxiliary material for briquettes that guarantees their quality after shaping. Primarily used in the briquetting process, it plays a supplementary role. The coal briquette binder is a crucial auxiliary material that determines the quality of the briquettes.
The coal molding adhesive is formed through complex chemical reactions involving inorganic substances and various organic chemical raw materials. When mixed with powdered coal, it quickly forms a needle-like and net-like structure, endowing the molded coal (coal balls) with high cold and heat mechanical strength and thermal stability; excellent moisture and water resistance; and high immersion strength. It has a high combustion value when burned in the furnace, resulting in high thermal intensity post-combustion with low breakage rate upon falling, contains no ash, causes no pollution, and is easy to operate.
Application Scope
1. Cold-press molding. Add the powdered coal binder to the well-mixed coal material, then press it 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 solution thoroughly, then form the mixture 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 coal, coal for gasification, and coal briquettes (pellets) for metallurgy. It can process waste materials, coal powder, and other by-products from coal mining and metallurgy industries into briquettes.
