Method for improving adaptability of cement
The invention discloses a method for improving cement adaptability, and relates to the technical field of cement, the method comprises the following steps: 1, modifying the upper part of a smoke chamber at the tail of a cigarette: changing the upper spiral shape of the smoke chamber into a trapezoid, increasing the effective distance from the upper spiral shape to a slope, and changing the material of a castable from an anti-skinning castable into a high-strength wear-resistant castable; secondly, a primary fan of the kiln head is transformed, wherein the power and the rotating speed of a motor are increased, and the outlet pressure of the fan is increased by 5000 pa; thirdly, ventilation transformation of the grate cooler is conducted, specifically, grate gaps of an air inlet device at the fixed end of the grate cooler are adjusted, and the grate gaps are increased to 1.5 mm from original 1 mm; fourthly, a first-stage material scattering plate is transformed, wherein the angle of the first-stage material scattering plate is adjusted to be 18 degrees; according to the invention, through the top modification of the smoke chamber at the tail of the smoke, the modification of the primary fan at the kiln head, the ventilation modification of the grate cooler, the modification of the first-stage material scattering plate, the adjustment of the sulfur-alkali ratio content in the clinker, the optimization modification of the first-stage flap valve and the adjustment of the grain composition of cement, through the technical modification, the method is more suitable for the use state of the desulfurized gypsum, and the quality of the clinker is further improved.
本发明公开了一种改善水泥适应性的方法，涉及水泥技术领域，步骤一、烟尾烟室上玄的改造：将烟室上旋形状改为了梯形，增加上旋到斜坡的有效距离，并将浇注料的材质由抗结皮浇注料改为高强耐磨浇注料；步骤二、窑头一次风机改造：提高电机功率及转速，风机出口压力提高5000pa；步骤三、篦冷机通风改造：将篦冷机固定端的进风装置篦缝进行调整，由原来的1mm增加到1.5mm；步骤四、一级撒料板改造：将一级撒料板角度调整到18°；本发明通过烟尾烟室上玄改造、窑头一次风机改造、篦冷机通风改造、一级撒料板改造、调整熟料中硫碱比含量、一级翻板阀优化改造、调整水泥颗粒级配，通过以上技术改造，更加适应了脱硫石膏的使用状态，进一步提高熟料质量。
