The invention discloses an integrated terrazzo preparation process which comprises the following steps: preparing 10-20% of silicate white cement, 50-70% of natural stone gravel, 20-40% of stone powder, 0.5-3% of iron toner and 0.2-1% of rubber powder, adding a water reducing agent, a defoaming agent, an anti-freezing agent, sodium citrate and water, and uniformly stirring and mixing. According to the terrazzo prepared by the preparation method, the amount of voids generated in the forming process is small, the density and the strength are high, the dirt-removing power is improved, and the iron toner, the rubber powder and the anti-freezing agent are introduced, so that the terrazzo is more attractive, good in deformation resistance and relatively good in anti-freezing performance; in the preparation process, optimally-arranged screen cleaning equipment is adopted, small broken stone residues in broken stones are cleaned out after the broken stones of the natural stone are put into the cleaning mechanism, the cleaned broken stones of the natural stone enter the screening mechanism, the natural broken stones meeting the use requirements are discharged and collected, and the natural broken stones are blocked and ripped by a pushing and scraping structure in the screening process; the screening effect is prevented from being affected when the natural broken stones are too many, and the screening efficiency is improved.
本发明公开了一种一体式水磨石制备工艺，包括硅酸盐白水泥10‑20％、天然石材碎石50‑70％、石粉20‑40％、铁系色粉0.5‑3％、胶粉0.2‑1％，并加入减水剂、消泡剂、防冻剂、柠檬酸钠与水一并搅拌混合均匀，本发明通过天然石材碎石和石粉的混合，在成型过程中产生的空隙量少，密度和强度高，提高了去污能力，且引入了铁系色粉、胶粉和防冻剂，使水磨石更具美观性，抗变形能力好，具有较好的抗冻性能；在制备过程中采用了优化设置的清筛设备，在天然石材碎石放入清洗机构内部后清洗出碎石内的小碎石渣，清洗后的天然石材碎石进入筛选机构使符合使用需要的天然碎石排出收集，筛选过程中推刮结构将天然碎石阻挡划开，以避免天然碎石较多时影响筛选效果，提高了筛选效率。
