The pulverized coal conveying pipelines of boilers in thermal power plants are wear-resistant and require leak-proof, anti-corrosion, rain-proof, anti-freeze and other factors to be designed. The main points are anti-wear and anti-corrosion. It has always been a key part of power plant maintenance. The comprehensive performance of the pipeline system, especially the wear resistance, is
I believe that in the alumina ball inquiry process, as shown in the figure above, you have encountered many situations. There are many types of alumina balls. The above refers to the distinction between activated alumina balls and inert alumina balls. The nature of the composition has a great influence on the use of alumina
Alumina ceramic grinding balls are made of high-purity alumina powder rolled by a ball forming machine or isostatically pressed and then sintered at high temperature. The density of 92 alumina balls is about 3.6, the Mohs hardness is 9, and the water absorption is about 0.01. %, the self-wear amount is 0.01. Because of the
Wear-resistant ceramic linings are mainly used in the thermal power industry (falling pipe lining), steel industry (blast furnace hopper, cylinder mixer), cement and building materials industry (raw material clinker chute), smelting industry (hopper), machinery industry ( Hopper), coal industry (transit station chutes), mining industry (transition chute hopper for primary breakage and fine breakage), chemical industry
With the continuous improvement of production capacity and blast furnace clinker ratio, the demand for physical output of sinter is getting higher and higher, and the contradiction between supply and demand of sinter is becoming increasingly prominent, which has become a bottleneck restricting the production and development of many companies. Due to the unreasonable lining
During the production of the blast furnace, iron ore, coke, and flux (limestone) for slag-making are loaded from the top of the blast furnace. The loading trolley plays an important role as the main means of transportation. Since most of the ore and coke loaded in the car have sharp edges The sharp edges and
Wear-resistant ceramic fan impeller refers to the paste AL2O3 ceramic sheet at the outlet of the fan impeller, the connection part of the blade and the rear disc to improve the wear resistance. On the basis of traditional fan manufacturing technology, using the technology of pasting wear-resistant ceramic linings, a surface layer with excellent wear
The medium-speed coal mill refers to a coal mill with a working speed of 50-300r/min. It is a professional equipment for the preparation of blast furnace ironmaking auxiliary materials. The medium-speed coal mill can provide suitable auxiliary material-coal powder for the blast furnace ironmaking system. The medium-speed coal mill is the most important large-scale equipment
1. Activated alumina ceramic balls have a certain adsorption effect and can be used to adsorb some polar substances. Simply put, activated alumina is active and will react with the material. Activated alumina ball has many capillary pores and large surface area, which can be used as adsorbent, desiccant and catalyst. At the same time,
The ceramic wear-resistant composite board adopts an advanced thermal vulcanization process to vulcanize toughened wear-resistant ceramics and rubber together to form a square ceramic rubber composite body, which depends on welding (three-in-one series) or high-strength adhesive bonding ( The two-in-one) method is fixed on the protective surface of the equipment to form a strong and
Alumina lining bricks products have the characteristics of high hardness, high density, low abrasion, good regularity, and corrosion resistance. Alumina bricks are used for wear-resistant linings of ball mills.
