Machine-made sand and preparation method thereof
The invention belongs to the technical field of highway construction or building construction machine-made sand application, and particularly discloses machine-made sand and a preparation method thereof. The machine-made sand is formed by mixing and crushing two or three or four of limestone, tuff, granite and pebbles according to the ratio of 1:(0.5-0.8):(1.2-1.5):(0.5-1) when the four components are adopted. According to the preparation method of the machine-made sand, efficient, safe and environment-friendly production is completed through a primary conveying assembly, a vertical crushing assembly, a screening machine and the like which are used in cooperation. The machine-made sand and the preparation method thereof have the beneficial effects that the design is reasonable, the automation degree of the sand making production process is high, the operation cost is low, the sand making rate is high, energy is saved, the yield is large, pollution is little, maintenance is easy and convenient, and the machine-made sand produced through sand making meets the national building sand standard and is uniform in particle size, good in particle shape, and reasonable in grading, and the prepared machine-made sand mixed mortar meets the standard requirements of on-site use.
本发明属于公路施工或建筑施工机制砂应用技术领域，具体公开了一种机制砂及其制备方法，所述机制砂，由石灰岩、凝灰岩、花岗岩、卵石组份的两种或三种或四种混合破碎组成，其中，采用四种组份时配比为1:0.5‑0.8:1.2‑1.5:0.5‑1，其制备方法，由相配合使用的初级输料组件、立式破碎组件、筛分机等完成高效、安全和环保式的生产。本发明的一种机制砂及其制备方法的有益效果在于：其设计合理，制砂生产过程自动化程度高，运行成本低，制砂率高，节能、产量大、污染少、维修简便，制砂生产出的机制砂符合国家建筑砂标准，粒度均匀、粒形好，级配合理，制备成的机制砂混合砂浆，满足现场使用标准要求。
