脱水屏幕
脱水屏幕 can be used to dewater -4 mesh (5 mm) particles of s和, 煤炭, 铁矿石, 盐, 等., 以及有限的效率精细上浆, 洗涤和漂洗, 脱泥和有机物筛选.
应用程序
脱水屏幕 have a wide variety of applications, 包括脱水, 脱泥, degritting, 冲洗, 擦洗, 上浆和洗涤. They are designed to produce a consistent drip-free product 和 h和le materials such as s和, 砾石, 碎料, 压裂砂, 工业金沙, 矿物砂, 坚硬的岩石, 贵金属矿石, 煤炭, 铁矿石, 盐和其他颗粒状物质.
Surface moisture as low as 7% has been achieved 用菠菜网最稳定正规平台_最全菠菜网大全脱水筛; however, 最终湿度取决于表面面积, 表面形态, 接触角. 更好的材料, 例如在物料100%通过100目(150微米)的细粒回收系统中处理的那些, 会脱水到无滴水的稠度吗, 它传递和堆叠, but may have a surface moisture content of more than 20%.
脱水筛是如何工作的
使物料有效脱水, 浆料被送入陡床, 脱水筛进料端筛面向下倾斜，实现快速排水. 当物质在稍微向上倾斜的表面上积聚时，山谷中开始形成一池水. 反向旋转振动马达(或最大脱水筛上的机械激振器)产生与筛面成一定角度的直线运动，使固体以5g的速度向上和向前加速. 这, 随着一个慷慨的笔画长度, moves water through the countless openings between the particles to promote droplet formation.
The abrupt reversal of motion detaches water from the material, 水滴通过屏幕介质. The solids are conveyed up the screen by this linear motion. 屏幕的上坡, 还有一个排水堰, 形成一个作为过滤介质的深床, allowing retention of material much finer than the screen openings. A thick bed of material promotes fine retention while allowing the water to migrate through.
哪里需要更清洁的材料, cross dams 和 spray bars can be included to assist with the washing process, 解放通过媒体传播的罚款. Using a dilute feed 和 additional spray water, these screens can effect some limited sizing. 脱水筛可用于有限效率细尺寸在10目或以上(2毫米)，以创建不同的菠菜网最稳定正规平台_最全菠菜网大全, for stone 洗涤和漂洗 <2” (-50 mm) aggregates prior to loadout, 脱泥, 用于垃圾/有机物脱水/筛选.
为什么使用菠菜网最稳定正规平台_最全菠菜网大全脱水筛
菠菜网最稳定正规平台_最全菠菜网大全脱水筛是 基于原始Velco脱水筛 它是在1970年代中期为矿物加工厂使用而开发的，现在是颗粒物料的主要脱水装置. 菠菜网最稳定正规平台_最全菠菜网大全使用横梁结构增强了这种设计，使机器更坚固，更容易维护. 菠菜网最稳定正规平台_最全菠菜网大全脱水筛是 designed for minimal maintenance. The bolt-together design allows for component replacement without cutting or welding. They require little operator training when installed 和 produce minimal noise.
这是对原始设计的又一改进, 菠菜网最稳定正规平台_最全菠菜网大全 engineered its screen media for heavy-duty applications. 这 media features longitudinal stringers for full-length support. 紧公差, 全长聚氨酯-聚氨酯接合几乎消除了工艺材料在筛管截面界面的进入, 防止在使用针套和多点支撑介质时出现麻烦的磨损点.
菠菜网最稳定正规平台_最全菠菜网大全率先使用纵向分隔器，允许多达三种菠菜网最稳定正规平台_最全菠菜网大全在一个屏幕上脱水. 许多应用程序的特点是双流进程, 但麦克菠菜网最稳定正规平台_最全菠菜网大全脱水筛允许一个细流和两个粗流保持分离或混合，以创造特殊菠菜网最稳定正规平台_最全菠菜网大全.
与典型的人相比 细料螺旋垫圈, the final product will generally be at least 10% drier with a 菠菜网最稳定正规平台_最全菠菜网大全 脱水筛. Because of the wide range of equipment within 菠菜网最稳定正规平台_最全菠菜网大全, the 脱水筛 can be combined to complement other process equipment, 如螺旋垫圈, 水力旋流器 和 分隔符™. 某些类型的洗涤过程(如.g. 双重洗涤)可以受益于螺旋洗衣机作为主要洗涤设备，辅以脱水筛为干燥菠菜网最稳定正规平台_最全菠菜网大全.

关于脱水屏风的FAQs
向专家请教一些应用程序经历了一个 含水率低至7% 用菠菜网最稳定正规平台_最全菠菜网大全脱水筛, but final moisture content is dependent on both surface moisture 和 inherent moisture. 当按重量报告水分时(kg水/kg纸浆), the specific gravity of the solids also plays a factor, with higher specific gravity materials showing lower moisture contents. If you remove all the water from the gaps between the particles, 唯一剩下的水是作为薄膜吸附在外表面或作为材料本身固有的水分(一些褐煤可以含有高达20%的固有水分)。. 因此, the finer the materials being h和led 和 the more irregular the surface, 水分含量越高. 某些材料也更疏水或亲水，这也影响残留水. 同样重要的是要了解脱水筛的作用对于在物料床底形成液滴至关重要. 这 combination of amplitude 和 frequency was studied by the University of Karlsruhe, 谁提出了这一行动的建议.
In the early days of 脱水屏幕, urethane pin 和 sleeve design media was common. 从那时起, 平行发展发生了, rated capacities increased (doubling in some cases) 和 more robust media designs came about. 今天, pin 和 sleeve style designs are perfectly adequate 和 appropriate for sizing screen applications; however, with the heavy loads 和 aggressive action on 脱水屏幕, few media manufacturers can match the mechanical integrity required for the application. 菠菜网最稳定正规平台_最全菠菜网大全花了很长时间研究和设计，以满足需求，结果是一个纵向轨道式系统，在介质和stringers之间采用聚氨酯对聚氨酯连接——这种类型的界面不会失败. 脱水筛中介质的更换频率是这样的，没有制造商或代表会损失很多下游收入, but the end user always benefits from a better system.
在设计脱水筛的支撑结构时，需要考虑几个因素, 包括部队, 固有频率和多单元装置. 菠菜网最稳定正规平台_最全菠菜网大全 can provide design criteria 和 assistance; call our offices for support or contact us now. 作为快速指南, 脱水筛不应低估其以900转/分和10毫米振幅的质量动摇结构的能力. Multiple 脱水筛 installations can be a challenge with harmonics; occasionally a beat will be experienced. In some cases, vibration transference through the ground can be experienced in other structures. 良好的设计实践包括在支撑点和坚实的基础下直接放置柱子以提供质量. 在动作方向(与筛管纵向)上，与其他部件保持3英寸(75毫米)的间隙，这样当振动电机或激振器在关闭过程中失相时，不会产生冲击. 电缆应始终从上方直接支撑/悬挂在接线盒上，不得悬挂在振动部件上. 菠菜网最稳定正规平台_最全菠菜网大全的脱水筛电机配有密封的接线盒，带有长电缆连接到电路中.
菠菜网最稳定正规平台_最全菠菜网大全’s personnel pioneered the use of deck-dividers to allow two or even three products to be dewatered at one time. 一边生产优质菠菜网最稳定正规平台_最全菠菜网大全，另一边生产粗劣菠菜网最稳定正规平台_最全菠菜网大全，并配有混合设备，这是麦克菠菜网最稳定正规平台_最全菠菜网大全标准菠菜网最稳定正规平台_最全菠菜网大全的一部分. Process engineers will assist with the application to ensure all factors are considered. 大量的不平衡负载(一个或多个菠菜网最稳定正规平台_最全菠菜网大全长时间不喂料)会降低设备的使用寿命.
The smallest aperture on a 脱水筛 is typically 50 mesh (0.3毫米)，因此您将期望在屏幕的下流中看到一些该尺寸的碎片和更细的碎片. Not all of that fraction will pass through due to the very nature of caking style screens; fines are captured in the bed formed on top of the media. The usable fraction that does pass through the screen can be h和led in several ways. The easiest is to recycle back to the device feeding the screen. In cases of greater flows, a dedicated scavenger circuit could be used.
