该中心传动浓缩机采用絮凝技术，矿浆直接输入到浓缩机的压缩区 域，在池内形成滤床层，从底部输入的矿浆中未絮凝的细小颗粒， 被水流冲上去经过滤床层时，与该层的颗粒相撞，由于絮凝剂的作 用，与其他颗粒结合在一起下沉，从而增加了底层浆液浓度，而上 层溢流水浓度下降，由于采用了絮凝剂，颗粒易形成凝聚团，沉降 速度大幅度加快，单位面积处理能力明显提高，是传统浓缩机的 4~8倍。 

The center drive thickener adopts flocculation technology. The pulp is directly input into the compression area of the thickener to form a filter bed in the pool. When the unflocculated fine particles in the pulp input from the bottom are washed up by the water and pass through the filter bed, they collide with the particles of this layer. The concentration of overflow water on the upper layer decreases, due to the use of flocculants, particles are easy to form agglomeration, the settlement rate is greatly accelerated, and the unit area processing capacity is significantly improved, which is 4 to 8 times that of the traditional thickener.

The collector cover is small and convenient for the operator to pass on the bridge.

布料装置：Fabric device: 

布料装置与旋转转笼设计为单独结构。矿浆经中心给料管（液面下给料）直接进入布料 桶，固体颗粒物在流体势能的作用下，沿布料桶向下运动，不同的粒度有不同的下降速 度，较大的颗粒因体积较大在重力的作用下，运动速度快， 所以先到达浓缩池底部，中等粒度随之下降到达底部；细小颗粒向浓缩池周边飘移并逐渐沉降。工作时对清水层不产 生干扰，对压缩层不产生冲击。 中心深层入料（液面下给料），矿浆进入稳流桶后，矿浆的流速大大降低，从而实现了平 流沉降，降低了固相颗粒的动能。并且，耙架为连杆式结构，它有效的减少对固体颗粒沉 降的干扰，较一般浓缩机处理能力可提高 30～50%。

The distribution device and the rotary cage are designed as separate structures. The slurry enters the distribution tank directly through the central feed pipe (feed under the liquid level). Solid particles move down the distribution tank under the action of fluid potential energy, and different particle sizes have different descending velocity. The larger particles move faster under the action of gravity due to their larger size, so they first reach the bottom of the concentration tank, and the medium particle size then drops to the bottom. Fine particles drift to the perimeter of the concentration tank and gradually settle. There is no interference to the clean water layer and no impact to the compressed layer. After the slurry enters the steady flow bucket, the flow velocity of the slurry is greatly reduced, thus realizing the flat flow settlement and reducing the kinetic energy of the solid particles. Moreover, the harrow frame is a connecting rod structure, which effectively reduces the interference to solid particle settling, and the processing capacity can be increased by 30 ~ 50% compared with the general thickener.
