细沙回收及整套设备主要由电机、渣浆泵、旋流器ZKR脱水筛、清洗槽、返料箱等组成。
细沙回收及泵将沙水混合物保送至旋流器，离心分级浓缩的细沙经沉沙嘴提供应振动筛，经振动筛脱水后，细沙与水有效别离，少量细沙等经返料箱再回到清洗槽，清洗槽液面过高，经出料口排出。直线振动筛回收物料重量浓度为70%-85%。调理细度模数可经过改动泵转速、改动沙浆尝试、调理溢流水量、改换出沙嘴来完成。
经济效益剖析：
假设沙石厂消费产量为90?/h,水泵出量80?/h洗沙机排出的废水中细沙量约为3%左右（2.5?/h），经细沙回收安装处置后，由细沙回收机安装排放的废水中细粉含量不到1%，细沙回收率达60%（2.5?/h*60%=1.5?/h）消费线每天按工作12小时计算：1.5?/h*12=18?/天，一年工作320天计算；18?/天*320天=5760?/年，废品沙按55元/?计算：5760?*55元/?=32万元，如沙石厂消费量，设备大则效益会更高，同时细沙得到充沛回收，减少了沉淀池的工作量，大大降低了沉淀池的清算本钱。
The fine sand recovery and the whole set of equipment are mainly composed of motor, slurry pump, zkr dewatering screen of hydrocyclone, cleaning tank, return tank, etc.
The fine sand recovery and pump will deliver the sand water mixture to the hydrocyclone. The fine sand concentrated by centrifugal classification is provided with a vibrating screen through the sand settling nozzle. After dehydration by the vibrating screen, the fine sand and water are separated effectively. A small amount of fine sand is returned to the cleaning tank through the return tank, and the liquid level of the cleaning tank is too high, and then discharged through the discharge port. The weight concentration of recovered materials is 70% - 85%. The fineness modulus can be adjusted by changing the pump speed, changing the sand slurry, adjusting the overflow water volume and changing out the nozzle.
Analysis of economic benefits:
Assuming that the consumption output of sandstone factory is 90? / h, The output of the water pump is 80? / h, and the fine sand in the waste water discharged by the sand washing machine is about 3% (2.5? / h). After the fine sand recovery and installation, the fine powder content in the waste water discharged by the fine sand recovery machine installation is less than 1%, and the fine sand recovery rate is 60% (2.5? / h * 60% = 1.5? / h). The consumption line is calculated by 12 hours of work every day: 1.5? / h * 12 = 18? / day, 320 days a year; 18? / day * 320 days = 5760? / year, waste sand According to the calculation of 55 yuan /?: 5760? * 55 yuan /? = 320000 yuan. If the consumption of sand factory is large, the benefit will be higher. At the same time, the fine sand will be fully recovered, the workload of sedimentation tank will be reduced, and the clearing cost of sedimentation tank will be greatly reduced.
