[0002] Refractory is a material that is resistant to heat, pressure or chemical attack and can maintain its strength and shape at high temperatures. Refractory is an inorganic non-metallic material with a porous and heterogeneous structure. They are usually composed of oxides of the following materials: silicon, aluminum, magnesium, calcium and zirconium.

[0003] A powder grinding machine generally uses a single rotating roller or a double rotating roller to extrude and grind the material into powder, and then collects the ground powder for screening. The existing powder grinding machine has a relatively simple structure. After the material to be processed is broken into pieces, it passes through the screen and enters the grinding and powdering process. Due to insufficient breaking, the volume of the material is uneven, which causes the material to get stuck in the grinding position and cause blockage, thereby affecting the powdering efficiency. For this reason, we propose a powder grinding machine for refractory material production. Utility Model Content
