Background Art

Refractory materials refer to materials that have strong fire resistance and do not soften under high temperature conditions. Due to their unique functionality, refractory materials are currently widely used in various fields such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, etc. They are indispensable basic materials in the above-mentioned fields and play an irreplaceable and important role. Currently, refractory materials require the use of grinding devices for grinding processing during the production process.

According to the search, it was found that a Chinese patent with patent number CN217392521U discloses a grinding device for refractory materials, including a supporting foot, a grinding box is fixedly connected to the top of the supporting foot, a feed port is fixedly connected to the middle of the top of the grinding box, a working chamber is opened in the grinding box, and a feeding mechanism and a grinding mechanism are arranged in the working chamber. When grinding work is required, the raw material is put into the grinding box through the feeding port, and the first motor is turned on at this time. When the first motor is working, the feeding plate is driven to rotate, and the raw material is separated and discharged when the feeding plate rotates. When the raw material falls on the first grinding roller, the second motor is turned on at this time.
