In order to make the large and medium-sized ferroalloy reduction electric furnace run better, it is required that the burden should have proper fragmentation and ensure good air permeability. At present, the supply of high-quality lumpy burdens which can be directly used in the furnace is becoming increasingly tight. In order to adapt to this situation, some manufacturers adopt various lumping technologies and use fine ore and concentrate to obtain better smelting indexes. Among them, high-pressure briquette machine pelletizing technology has become a new development direction of ferroalloy pelletizing technology in recent years because of its simple process, fuel-saving, applicability to fine ore, and a wide variety.

The quality of the briquetting machine determines the ball rate and strength of the briquettes pressed out by the machine, which is the focus of the vast number of users. There are three standards to judge the overall performance of the briquette machine, which are: briquetting pressure, briquette strength, and briquette hardness.

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.
