Introduction

Refractory products processed by grinding machine can be used in thermal equipment such as coke oven, glass furnace, acidic steel-making furnace, alkaline steel-making furnace, non-ferrous metal smelting furnace and cement kiln, and amorphous refractories such as filler, refractory ramming, refractory castable, refractory plastics, refractory clay, refractory spraying. Feeding, refractory projecting material, refractory coating, light refractory castable and gun mud. High-pressure medium-speed mill can be used for making powder of refractory materials, especially for diatomite brick, vermiculite, rock wool, asbestos, diatomite brick, vermiculite, rock wool, asbestos, etc. The fineness of the finished product can be adjusted freely in the range of 80-425 mesh, and can produce 30-80 mesh coarse powder by adding special equipment.

Refractories are used in various fields of national economy, such as iron and steel, non-ferrous metals, glass, cement, ceramics, petrochemical industry, mechanical science and technology, boiler, light industry, electric power, military industry, etc. They are essential basic materials to ensure the production and operation of the above-mentioned industries and play an irreplaceable role in the development of high-temperature industry. Effect. Since 2001, the refractory industry has maintained a good growth momentum, and has become a major producer and exporter of refractories in the world, driven by the rapid development of high-temperature industries such as steel, non-ferrous, petrochemical and building materials. In 2011, China's refractories accounted for about 65% of the world's total production and sales, ranking first among the world's refractory materials. AZS bricks, corundum bricks, magnesia-chromium bricks, silicon carbide bricks, silicon nitride-bonded silicon carbide bricks, nitrides, silicides, sulfides, borides, carbides and other non-oxide refractories are often used; calcium oxide, chromium oxide, alumina, magnesium oxide, beryllium oxide and other refractories. Often used thermal insulation refractories include diatomite products, asbestos products, insulation panels, etc. Often used amorphous refractories are refractory, ramming, castable, plastics, refractory, gunning material, projectile, paint, lightweight refractory castable, mud and so on.
