Formula sand production process

The invention discloses a formula sand production process. The device comprises a plurality of sand bins for storing sand particles with different sizes, wherein a metering scale and a microcomputer metering system are arranged below each sand bin. The sand grains with different specifications and models are respectively and independently stored, and the proportions of particles with different sizes in the sand grains are accurately determined through the metering scale and the microcomputer metering system; therefore, the accurate control of the grain composition of the artificial sand is realized, the quality of the prepared finished sand is improved, the use requirements of different occasions can be met by blending the sand grains with different proportions, the adaptability of the finished sand is improved, and the quality is stable, the fineness and the modulus are accurate. 本发明公开了一种配方砂生产工艺，包括存放砂粒大小不同的若干砂仓，在每个所述砂仓下方安装有计量秤以及微机计量系统；将不同规格型号的砂粒分别单独存放，并通过计量秤以及微机计量系统来精确砂粒中不同大小颗粒的比例，进而实现了人工砂颗粒级配的精确控制，提高了制成的成品砂
