Abstract

The invention discloses a grinding roller and a grinding disc tile. The grinding roller and the grinding disc tile comprise basal bodies and multiple ceramic rods, wherein the ceramic rods are casted in the basal bodies along the abrasive surfaces of the grinding roller and the grinding disc tile. The grinding roller and the grinding disc tile provided by the invention guarantee that the working layers of the grinding roller and the grinding disc tile have higher hardness, the adhesive wear and the cutting abrasion are reduced on one hand when the wearable ceramic rods are casted in the basal bodies, and the grinding roller and the grinding disc tile are guaranteed to have good tenacity on the other hand to resist exotical impact. The grinding roller and the grinding disc tile provided by the invention adopt routine antifriction material to support and protect a ceramic material, the super stiff and wearable ceramic material is utilized to grind the processed mineral, and the advantage composite matching of the material is realized.

Description

technical field [0001] The invention relates to milling equipment in thermal power plants, cement, metallurgy and other industries, in particular to grinding rollers and grinding tiles. Background technique [0002] As the key components of vertical mills (or medium-speed mills), grinding rollers and disc tiles are usually used in the milling and processing of mineral raw materials in industries such as electric power, metallurgy, building materials, chemicals, and mining. Due to the direct application of force on the mineral raw materials, the wear is severe and the replacement is frequent, so the cumulative service life is an important indicator for evaluating the quality of the grinding roller and the grinding disc tile. [0003] At present, there are mainly two ways to improve its cumulative service life, that is, to use harder and wear-resistant materials, or to form a harder and wear-resistant structure on the surface of the product by spraying, cladding, surfacing or ...
