Thickeners
Thickeners — or Clarifiers, 根据应用-可用于立即回收可重复使用的工艺水, as well as extract fines and other materials. Thickeners are used by mineral and aggregate producers, 以及废水管理等行业的环境承包商, to separate solids from liquid in a slurry.

${ card.header }根据生产商的需求和行业，增稠剂的好处可能因用户而异.
For instance, 增稠剂可用于水供应短缺或非常昂贵的地方, providing immediately reusable process water back to the plant. 它们还可用于减小沉降池或尾矿储存设施的规模. When combined with other downstream processing equipment, such as a Filter Press, Thickeners can potentially eliminate settling ponds altogether. 在一些工业中，它们被用作澄清剂，从工艺水中去除矿物质和细粒.
Why McLanahan Thickeners
With McLanahan Thickeners, 生产商可以回收高达90%的水进行再利用，以创造更可持续的运营. They are ideal for sites where water is scarce or expensive. 麦克菠菜网最稳定正规平台_最全菠菜网大全增稠剂还减少了报告浪费的材料数量. 这使得生产商可以减少其沉淀池或尾矿储存设施的规模, which can be expensive and dangerous to maintain, 引起许可问题，并可能覆盖可开采储量.
大多数麦克菠菜网最稳定正规平台_最全菠菜网大全增稠机(但不是全部)采用低轮廓耙设计与或不脱水桩, 耙驱动由液压动力组或直接耦合机电齿轮箱提供动力. 基于计算流体动力学(CFD)建模的现代馈井设计确保了絮凝剂的最小使用. Optional sensors for monitoring bed level, 下流密度和溢流浊度确保最佳运行.
Types of Thickeners
McLanahan offers a range of thickener types, including High-Rate, Ultra Rakeless, High-Density and Paste, that are tailored to an individual application. 它们可以作为独立的解决方案或与其他设备结合使用.
High-Density Thickeners
高密度增稠剂排出的底流泥浆屈服应力在50- 100pa之间., which can be pumped with a centrifugal slurry pump. 它们通常的特点是具有较高的侧壁以提供增强的压缩效果, 更陡的底板坡度有助于将固体移至卸料区，低轮廓耙结构与尖桩相结合，加强床层脱水. High-Density Thickeners are available with on-ground, flat-bottom tanks or elevated tanks, 哪一种能缩短抽气管线，降低抽气要求.
High-Rate Thickeners
高速率增稠剂用于骨料和采矿业, as well as environmental contractors, to recover approximately 85% of water for reuse. 这种高水平的水回收使水消耗保持在可持续的水平, 以及大幅减少泥浆体积报告到废物池. 他们使用最少量的絮凝剂来快速沉淀悬浮在泥浆中的颗粒, making High-Rate Thickeners environmentally friendly. High-Rate Thickeners can be supplied with flat-bottom, on-ground tanks or elevated tanks, 哪种泵的吸油管线较短，可以降低堵塞的风险.
Paste & Ultra Rakeless Thickeners
膏体增稠剂仅靠重力就能达到最高的固体浓度, 最大水回收率高达90%，排出的泥浆屈服应力大于150pa. Because of high percentage of solids in the mud, 生产商可以大大减少其沉淀池或尾矿储存设施的规模. 膏体增稠机的特点是具有高侧壁和陡峭的底板斜坡，以帮助泥浆的压缩效果. 耙桩系统由坚固的驱动器驱动，有助于在泥床上形成脱水通道, allowing further compaction of the mud. The Ultra Rakeless Thickeners (ULT) is similar, 但特点是更深的泥床和更陡峭的地面斜坡，以帮助压缩泥浆，而不使用耙子.
Frequently Asked Questions About Thickeners
Ask An Expert要确定应用程序的正确增稠剂，请执行以下操作 laboratory tests should be undertaken:
- Feed characterization
- Settling flux to establish the optimum solids for maximum rate
- 在最佳固体条件下进行静态圆柱体试验，以确定自由沉降率
- Dynamic cylinder testing to confirm an acceptable flux rate
- Extended deep tube testing to determine mud residence times
- Yield stress (rheology) curve to confirm required rake torque
- Indicative flocculant and/or coagulant dose
Subsequent to laboratory testing, a pilot plant test can be used to demonstrate viability at a larger scale; however, McLanahan可以在实验室测试工作的基础上提供过程保证.
提升装置是与驱动头相连的机械附件，可将增稠机的整个耙机构从泥床中抬起. While not always necessary, 耙式举升通常用于提供一些防止增稠器陷入泥潭的保险. 进料或絮凝条件是否改变，过程控制工具是否不足或无效, 一旦测量到预设的驱动扭矩，耙升就会被编程激活. 假定驱动扭矩由于泥浆厚度的增加而增加. By lifting the rake mechanism out the thick mud, 作业者可以争取一些时间，在前倾驱动失速之前处理条件的变化. Watch How A Thickener Works to see how the rake lifts when torque conditions are high.
在浓密机中，给料井的作用是在合适的剪切条件下混合浆料和絮凝剂，以促进最快的自由沉降. 它的目的是将水平进料动量转化为温和的垂直运动. 实现适当的速度和剪切条件对于最小化聚合物消耗至关重要. 进料井可以自动或强制稀释浆液进料，以获得测试程序中确定的最佳固体水平. Watch How A Thickener Works 观察进料井如何混合和分配浆料颗粒.
Thickener costs vary due to the wide range of duties and styles. Please consult your local McLanahan representative to identify the most cost-effective option for your application.
