Composite dry sand and preparation process thereof
The invention discloses composite dry sand and a preparation process thereof, relates to the technical field of composite dry sand, and aims to solve the problems that the ratio of raw material components for preparing the composite dry sand is relatively fixed, the performance advantages of the composite dry sand are difficult to play when the composite dry sand is used in different environments, and the use effect of the composite dry sand is reduced. And the prepared large-particle composite dry sand can also reduce the use effect of the composite dry sand. The method comprises the following steps: step 1, preparing 60-80% by mass of stone chips, 10% by mass of silt, 5-20% by mass of machine-made sand and 5-10% by mass of gobi sand; 2, stone chips, silt, machine-made sand and gobi sand are added into a preparation device together; step 3, evaporating and removing moisture of the material at high temperature; 4, a second motor is started to drive a crushing roller to rotate, and the rotating crushing roller is used for crushing the materials; 5, screening the crushed composite dry sand by using a screen with the fineness modulus of 3; and 6, a fifth motor is started to drive the first conveying belt to move.
本发明公开了一种复合干砂及其制备工艺，涉及复合干砂技术领域，为解决复合干砂的制备原料组分比相对固定，在不同环境下使用复合干砂，复合干砂的性能优势难以发挥出来，使得复合干砂的使用效果下降，而制备出来大颗粒的复合干砂同样会降低复合干砂的使用效果的问题。步骤1：准备质量百分比为60～80％的石屑、10％的泥沙、5～20％的机制砂和5～10％的戈壁砂；步骤2：将石屑、泥沙、机制砂和戈壁砂一同添加到制备装置中；步骤3：利用高温将物料的水分蒸发去除；步骤4：开启第二电机带动碎料辊旋转，利用旋转的碎料辊将物料碾碎；步骤5：使用细度模数为3的筛网对碾碎的复合干砂进行筛选；步骤6：开启第五电机带动第一输料带运动。
