Admixture, preparation method and device thereof, machine-made sand fair-faced concrete, and preparation method and device of machine-made sand fair-faced concrete
The invention relates to the technical field of building materials, and concretely relates to an admixture, a preparation method and device thereof, a machine-made sand fair-faced concrete, and a preparation method and device of the machine-made sand fair-faced concrete.The screen mesh aperture of a primary screening drawer screen is greater than that of an adaptive drawer screen, so that the primary screening drawer screen can perform primary screening on the machine-made sand; a filter screen driving component drives the primary screening drawer screen and the adaptive drawer screen to do reciprocating horizontal movement, so that machine-made sand located on a screen cloth moves uniformly, and after the machine-made sand is screened, the machine-made sand with the small particle size falls onto the adaptive drawer screen; and a rubbing and grinding component makes reciprocating movement on the adaptive drawer screen, so that the machine-made sand falling onto the matched drawer sieve is subjected to shape edge rubbing and grinding, the machine-made sand with the more appropriate shape is obtained, the machine-made sand with the appropriate particle size and shape is obtained by taking out the matched drawer sieve, and then the preparation effect of the fair-faced concrete is better.
本发明涉及建筑材料技术领域，具体涉及一种外加剂、机制砂清水混凝土及其制备方法和装置，初筛抽屉筛子的筛网孔径大于适配抽屉筛子的筛网孔径，进而初筛抽屉筛子能够对机制砂进行初筛，滤筛驱动构件驱动初筛抽屉筛子和适配抽屉筛子进行往复的水平运动，使得位于筛网上的机制砂进行均匀移动，机制砂被分筛后粒径较小的机制砂掉落到适配抽屉筛子上，搓磨构件通过在适配抽屉筛子上进行往复的运动，从而对掉落到适配抽屉筛子上的机制砂进行外形棱角的搓磨，以获取形状更为合适的机制砂，通过取出适配抽屉筛子，从而获取粒径和形状合适的机制砂，进而使得清水混凝土的制备效果更好。
