Sand Washing Plants

麦克菠菜网最稳定正规平台_最全菠菜网大全洗砂厂将沙子从其原始状态加工成符合各种规格的菠菜网最稳定正规平台_最全菠菜网大全. The process requirements vary depending on the input and desired output, but plants typically scrub, liberate, deslime, wash, classify, decontaminate and dewater the sand, as well as process the effluent stream that results.

Applications

Sand Washing comes in many forms and covers a range of feed and products produced, including construction aggregates such as concrete, asphalt, mason, mortar, and plaster sands; sports sands such as for golf courses, ball parks, and race courses; industrial sands, such as glass, filter, foundry, and frac; specialty sands and materials such as anti-skid, roofing granules; deligniting/organics removal; and soils washing for environmental projects.

对于有兴趣最大限度地提高产量并根据最终用户的需求和规格生产精确分级菠菜网最稳定正规平台_最全菠菜网大全的客户, it is more likely that a custom sand plant is the correct solution. Whether the sands are natural or manufactured, fine or coarse, well or poorly graded, or required for specialty applications, McLanahan can offer a plant specifically designed to suit your needs.

How Sand Washing Plants Work

洗砂厂涵盖了从原料状态到成品状态的各种过程. These process can include:

  • Feed Preparation -原料饲料在加工前,必须使用以下组合配制 Attrition Cells, Blade Mills, Coarse Material Screw Washers, Log Washers and Rotary Scrubbers. The objective is to bring all materials into suspension, 基本上是分解任何粘土和粘土结合的材料,去除表面的污染.
  • Sizing – Prior to and immediately after the feed preparation step, 原料必须筛选成适合下游工艺和生产菠菜网最稳定正规平台_最全菠菜网大全的馏分. Vibratory Screens are typically used.
  • Pumping – Centrifugal Slurry Pumps 浆料从一个工厂/过程转移到另一个工厂/过程的首选方法是什么. Pumps are also used for effluent disposal. Although there can be resistance to using a pump over a gravity-fed unit, a gravity-fed unit may not be able to capture saleable materials. 这些损失直接浪费掉了,从长远来看,最终会让你花钱.
  • Desliming -如果进料中存在大量的游离超细物料, 通常需要在分类前除去这一有害部分. 高悬浮黏土含量会对分级效率产生不利影响, leading to losses of saleable materials and dirty products. Cyclones 是首选的脱泥设备,因为他们的高剪切和高效分级. 饲料调节池也非常合适,特别是在疏浚应用中发现的高容量的地方. 控制溢流可以降低泵送至下游分级的功率消耗. Occasionally, desliming or simply washing is all that is needed to create the final product by removing the <75µm (<200 mesh) down to a certain level, such as 3-5% passing.
  • Classifying -这是根据大小或比重将颗粒相互分离的过程. In sand washing, this applies to the <4mesh (<5mm) particulates. The procedure may involve making single sharp separations with our Hydrosizer™, or multiple size classifications with our Classifying Tanks. 在哪里生产特种砂,例如用于玻璃、压裂、运动、过滤器、铸造等., a Hydrosizer™ provides the accuracy needed for the splits in product gradation. Cyclones and Separators™ 分类装置是否也在140目(105微米)和更细的尺寸分离范围内工作,通常比使用加氢筛的范围更细.
  • Deligniting/Organics Removal - This process is the classification of materials based on their specific gravity. 在聚合应用中,根据整体工艺设计,可以选择加氢器™或加氢器™ LitesOut™ is used to reject +50 x 4mesh organics of 1.4 – 1.8 SG. 我们使用ASTM C123测试轻质材料,其中使用重液体来定义污染物的比重. 在某些情况下,砂和褐煤之间的比重差是微不足道的, 我们可以在我们的实验室里运行一个测试来评估在加氢筛™中的重介质分离. 应始终理解,最终菠菜网最稳定正规平台_最全菠菜网大全并非无褐煤,但将根据ASTM C123通过.
  • Densifying and Dewatering – Certain types of equipment, like Hydrosizers and Attrition Cells, require a dilute slurry to be concentrated. Cyclones or Separators™ are most commonly used for this purpose. 分离器™特别适合这一任务,能够调节流量密度. In the case of dewatering, Fine Material Screws, Dewatering Screens or Separators™ are the most common devices. The lowest moisture content, by far, is obtained with a Dewatering Screen. With improved safety (less cleanup around the conveyors), 更好的管理(几乎没有从库存中排水)和更及时的供应, 脱水筛已成为最终菠菜网最稳定正规平台_最全菠菜网大全脱水的首选设备.
  • Effluent Treatment – Water is a very valuable commodity, 因此,将水回收电路作为任何许可程序的一部分正在成为一项要求. The device most common for this purpose is a Thickener. In most cases, 85% of the process water can be recovered for reuse. 最具成本效益的储存方法是专用水箱,以减少与池塘相关的渗透和蒸发损失. These tanks also save on the power requirement to pump the water out and back.
  • Waste Solids Management – While Thickeners can recover process water, 底流相对较稀,通常被泵送到遏制池. 完成洗砂过程,使废固料处于可运输和可堆放的状态, Filter Presses are typically employed.
  • Sampling - Every system requires monitoring and sampling to provide the best results. McLanahan can design a sampling system up front to focus on the key areas. The ability to react faster to process changes helps eliminate waste, improve product quality and troubleshoot problems.

基于分类槽的砂厂可以从单一饲料中产生多种菠菜网最稳定正规平台_最全菠菜网大全,并去除黏液和多余的水. Feed material enters the Sand Classifying Tank first, and sand grains settle in sections according to size down the length of the tank. 每个部分底部的阀门将颗粒释放到用于制造初级的几个水槽中的一个, secondary or tertiary product, depending on the application. The discharged products are then dewatered by Dewatering Screens and/or Fine Material Screw Washers. 添加旋风和/或上升水流可用于去除饲料.
