Process for producing sand for construction through dehydration and desliming
The invention relates to a process for producing sand for construction through dehydration and desliming. The process comprises the following steps of: 1, carrying out equipment type selection, demonstration and comparison; 2, carrying out screen surface material type selection test; 3, carrying out screen seam width test; 4, determining the height of an ore baffle at the ore discharge end of a sieve plate; 5, designing the inclination angle of the screen surface; 6, determining the vibration frequency and amplitude; 7, desliming with a second-section sieve; and 8, separating and recycling undersize mud and water. According to the technical scheme, the sand quality standard in the building industry is met, the tailing resource utilization rate is increased, the stacking amount is reduced, the occupied tailing pond capacity is reduced, overflow water is clarified and recycled and is not discharged, no pollution is generated, and the process has an important effect on the ecological environment.
本发明涉及一种脱水脱泥生产建设用砂工艺，所述工艺包括以下步骤：步骤1、设备选型论证比较；步骤2、筛面材质选型试验；步骤3、筛缝宽度试验；步骤4、筛板排矿端挡矿板高度；步骤5、筛面倾角设计；步骤6、振动频率和振幅；步骤7、第二段筛子脱泥；步骤8、筛下泥水分离循环利用。该技术方案满足建筑行业用砂质量标准，提高了尾矿资源利用率，减少堆存量，降低占用尾矿库库容，溢流水澄清再利用，无外排，不产生污染，对于生态环境具有重要作用。
