The invention relates to the technical field of artificial sand, especially to a preparation method of natural efficient artificial sand for precoated sand. The preparation method comprises the following steps that 0.8-3 parts of quartzite is uniformly fed into a jaw crusher by a vibrating feeder for crushing; coarsely crushed ore particles are conveyed to a cone crusher by a belt conveyor for intermediate crushing; after intermediate crushing, the ore particles are sent into a 8-to-40-mesh sieve for screening; the ore particles meeting requirements are fed into a sand making machine for finecrushing and shaping; the ore particles with proper particle size are conveyed to a sand washer for cleaning and impurity removal treatment; the quartz having undergone cleaning and impurity removal are added into a stirring device, 0.4-3 parts of a modifier is added, and stirring is conducted for 10-20 minutes; and a uniformly mixed material obtained in the above step is feed into a drying device, the temperature in the drying device is adjusted to 90-120 DEG C, drying is carried out for 40-80 minutes, and after drying by the drying device, cooling is conducted to obtain the granular artificial sand.
本发明涉及人工砂技术领域，尤其涉及一种用于覆膜砂上的天然高效人工合成砂制备方法，将0.8‑3份石英岩由振动给料机均匀的送入颚式破碎机进行粉碎，粗碎后的矿石颗粒由皮带输送机送圆锥破碎机进行中碎，中碎后送入8‑40目筛中进行筛分，将满足要求的矿石颗粒送制砂机进行细碎和整形，粒度大小合适被送洗砂机进行清洗除杂处理，将清洗除杂处理后的石英送入搅拌装置，并加入0.4‑3份改性剂，搅拌10‑20分钟，将S2中混匀的物料投入烘干装置内，烘干装置内的温度调节至90‑120℃，烘干时间为40‑80分钟，烘干装置烘干后，经冷却后即得到颗粒人工砂。
