Ball press machine is a type of machine that is used to press powder materials into balls or briquettes. It is commonly used in industries such as metallurgy, chemical, coal, and refractory materials. The machine works by applying high pressure to the powder material, forcing it through a die and forming it into a ball or briquette shape. The resulting balls or briquettes can be used for various purposes such as fuel, smelting, or chemical reactions.Its working principle can be described as follows：
The raw material is fed into the hopper of the ball press machine.
The screw propeller in the hopper rotates and pushes the raw material forward.
