Description

A grinding process and equipment for ceramic raw materials

technical field

The invention relates to a grinding process and equipment for ceramic raw materials.

Background technique

The invention relates to the field of ceramic raw material grinding technology and equipment, and proposes a new grinding technology using two grinding equipment. Grinding of ceramic raw materials is the process of processing coarse ceramic blocks into powdered finished raw materials in grinding equipment. Grinding equipment refers to a roller mill that uses rollers and grinding discs to crush materials. The process is as follows: Coarse particles first enter the coarse grinding roller mill with two larger diameter rollers to be ground, and the working surface of the rollers and the grinding disc is made of wear-resistant steel surfacing layer, which can withstand greater impact and impact It is beneficial to the crushing of bulk materials.

After sieving and removing iron, the worn iron and other impurities are removed, and the fine particle raw materials are sent to a fine grinding roller mill with three rollers with a smaller diameter for grinding and grinding. The rollers and grinding discs of the mill are lined with industrial ceramic blocks, which are more wear-resistant than the metal surfacing layer and prolong the service life. After the industrial ceramic blocks are worn, no iron will enter the ceramic raw materials, which avoids damage to the final ceramic product. The problem of adverse effects on quality, at the same time, compared with the current process of using 1 grinding equipment, 2 sets of grinding equipment have improved the grinding efficiency and the output per unit time.

In the existing grinding process, if one set of grinding equipment is used and industrial ceramic blocks are used as the working surface of the roller and the grinding disc, the industrial ceramic block is not easy to install due to the large diameter of the roller, and the tangential force is large. To withstand large impact and impact force, the brittleness and low toughness of ceramic materials make it easy to crack and damage, and lose the ability to work.
