In recent years, the increasing application of refractory and the better fire resistance have boosted the development of iron and steel development, cement enterprise, highway, construction. The most important reason for the rise of refractory is the technological reform.
From the production technique of refractory, there are sintering process, melting processes and molten injection method. The sintering process is part of the raw pre-firing the clinker, split (required mill or Raymond mill processing) and screening, and then bound to the ratio of assimilation with the raw material, molding, and drying machine. The casting method is the raw material lead powder after mixing the ingredients and dehydration equipment, fine grinding processes, direct casting, cooling and crystallization, annealing become products; financial injection method is to melt the ingredients in the low-temperature melting, low pressure air or too dry hot steam injection, and so into the fiber or the preparation of hollow spheres, respectively.
No matter what kind of production process, which has a Raymond mill (Raymond mill), figure, after Raymond machine's processing of small particle size, a minimum of 0.010 mm particle size, which fully meet the refractory needs of the processing of raw materials, so that the particles fully condensing grab and insulation line increased, the quality of finished products made from lighter, superior fire resistance and insulation properties.
