The briquette machine is a machine that presses powdery substances after stirring. In the process of pressing, it not only depends on the ball press itself but also needs an additive with strong viscosity and not easy to break, that is, a binder.

When the pulverized coal of the metal oxide briquette machine is pressed, it is confronted by the internal friction of the coal particles, which hinders the movement and approach of the coal particles.
