CGS型细砂回收装置 Fine sand recovery unit

一、工作原理
I. Working Principle

1、结构：由电机、碴浆泵、泥砂分离器、ZKR直线振动筛、清洗槽、返料箱等到组成。

1. Structure: this unit is composed of motor, slag and slurry pump, silt separator, ZKR rectilinear vibration sieve, wash tank and return box etc.

2、工作过程：泵将砂水混合物输送至泥砂分离器，离心分级浓缩的细砂经沉砂嘴提供给振动筛，经振动筛脱水后，细砂与水有效分离，少量细砂、泥等经返料箱再回到清洗槽，清洗槽液面过高时，经出料口排出。直线振动筛回收物料重量浓度为70%—85%。调节细度模数可通过改变泵转速、改变砂浆浓度、调节溢流水量、更换出砂嘴来实现。从而完成清洗、脱水和分级三种功能。

2. Working process: the pump transmits the sand-water mixture to silt separator; the enriched fine sand through centrifugal classification is conveyed to vibration sieve via desilting mouth; the fine sand and water is effectively separated after dehydration by vibration sieve; a small amount of fine sand and silt returns to wash tank via return tank. When the level inside wash tank is too high, the liquid will be discharged from discharge port. . The material recovery weight concentration of rectilinear vibration sieve is 70%-85%.. The fineness modulus can be adjusted by changing pump speed, sand pulp concentration, adjusting overflow water and replacing sand output port so as to perform the washing, dehydration and grading functions.

二、特点及优势
II. Features and Advantages

1、传统人工砂湿法工工艺中，人工砂的洗泥、脱水采用螺旋洗砂机，人工砂中细砂的流失几乎不能控制。采用该细砂回收系统，可以有效降低细砂的流失量，使其控制在5-10%之内。很好地解决了人工骨料加工系统中出现的成品砂细度模数偏高、石粉含量偏低的难题。

1. The silt washing and dehydration for manufactured sand is made using spiral sand washer in traditional wet technology; hence, the loss of fine sand from manufactured sand is hardly controllable. . This fine sand recovery system can effectively reduce the loss rate of fine sand and keep this rate at 5-10%.. This provides a perfect solution for the excessively high modulus of finished fine sand fineness and excessively low rock powder content that occurs in artificial aggregate processing system.

2、振动筛采用聚氨酯筛网，聚氨酯筛网较其它类型筛网寿命更长，且不易堵孔。

2. The vibration sieve is made of polyurethane screen mesh which has a longer service life than other types of screen meshes and a lower hole-blocking possibility.

3、泥砂分离采用聚胺脂整体浇铸成形，提高了整个装置的使用寿命，可顺利完成料浆浓缩、液体澄清等工作。

3. The silt separator is made of polyurethane through integral casting. In this way, the service life of the complete unit is improved and the pulp concentration and liquid clarification etc. can be done without interruption.

4、****可回收排放总量中85%-90%的细颗粒物料具有其他设备无可比拟的技术和经济优势。

4. The fine-particle material accounts for 85%-90% of the maximum discharge quantity that can be recovered. This presents unexampled technical and economic advantages.

5、细粒得到充分回收，减少了沉淀池的工作量，降低了沉淀池的清理成本。

5. Fine particles are thoroughly recovered to reduce the work load of settling tank and thus to reduce the clean-up costs thereof.

6、减少了细料自然堆放时间，可直接转运，供应市场。

6. Reduce the natural piling duration of fine materials since they can be transported directly to supply the market.

7、可根据用户的不同要求，设计相应的解决方案。

7. The solutions can be designed according to various requirements of customers.
