Preparation method for preparing aggregates of different grades by utilizing muck
The invention relates to the technical field of aggregate preparation, and discloses a preparation method for preparing different grades of aggregates from muck, which comprises the following preparation steps: 1) drying and scattering muck and a gelling material, and stirring and mixing to form a mixture; 2) placing the mixture on a rotating disc; the rotating disc obliquely rotates, an exciting agent is sprayed through a spraying structure and mixed with the mixture, and the mixture is extruded by centrifugal force to form a granular semi-finished product; (3) vibrating and screening the granular semi-finished product into various granular aggregates with different grades; (4) solidifying the aggregate; in the preparation step (1), a gelling material comprises Portland cement, calcium oxide solid waste, a gypsum material, a metal tailing material and a metakaolin material; in the preparation step 2), the exciting agent comprises an early strength agent, a water reducing agent, a water glass material and a mud blocking agent; a large amount of waste muck can be effectively consumed, the muck is prepared into unfired ceramic or synthetic sand, and the method has the advantages of energy conservation and emission reduction.
本发明涉及骨料制备的技术领域，公开了利用渣土制备不同等级骨料的制备方法，包括以下制备步骤：1)、将渣土以及胶凝料进行烘干以及打散，进行搅拌混合形成混合料；2)、将混合料置于转动盘；转动盘倾斜转动，通过喷洒结构喷洒激发剂，激发剂与混合料混合，混合料受离心力挤压形成粒状半成品；3)、粒状半成品振动筛分，筛分为多种不同等级的颗粒状的骨料；4)、将骨料进行固化；制备步骤1)中，胶凝料包含有硅酸盐水泥、氧化钙类固废料、石膏料、金属尾矿料以及偏高岭土料；制备步骤2)中，激发剂包含有早强剂、减水剂、水玻璃料以及阻泥剂；可以有效消纳大量的废弃渣土，将渣土制备呈免烧陶瓷或合成砂，具有节能减排的优势。
