在蒸压灰砂砖生产中,双轴搅拌机是不可缺少的一种设备。双轴搅拌机轴上的搅刀叶片在搅拌混合料时,不但受到径向摩擦阻力,而且还要受到轴向摩擦阻力,使叶片磨损加剧,成为极易磨损的零件。经常更换搅刀叶片不但费时费工,而且要消耗大量的钢材和影响设备运转率,从而增加生产成本。我省部分蒸压灰砂砖厂用自贡市硬质合 In the production of autoclaved sand-lime bricks, the biaxial mixer is an indispensable device. The blade of the mixing blade on the shaft of the twin-shaft agitator is not only subjected to radial frictional resistance but also subjected to axial frictional resistance when stirring the mixture, which makes the blade wear more severe and becomes an extremely wearable part. Frequent replacement of mixing blades not only takes time and labor, but also consumes a large amount of steel and affects the equipment operation rate, thereby increasing production costs. Some of the autoclaved lime sand brick factories in our province have been used in Zigong City
