lite - out™平底分类器

平底分类器 are part of the family of hindered settling classification equipment that includes 菠菜网最稳定正规平台_最全菠菜网大全 Hydrosizers™. These units use a dense fluidized bed of near-size sand to float off lightweight materials while allowing heavier fractions to pass through the bed.

平底分类器 are primarily used by aggregate producers in the production of construction sands but can also be used in specialty sands production, 当有机物存在时，包括玻璃砂和压裂砂. This technology is also utilized in soils washing for contaminated sites. 通常，多氯联苯等污染物集中在有机物中. The Lites-Out™ is excellent for this application where the organics are separated from the sand for disposal and the sand can be reused.

life - out™平底分类器是如何工作的

在典型的lite - out™系统中，平底分类器由一个 水力旋流器 提供有控制的、密集的和脱泥的饲料. 浆液通过中央进料井进入装置顶部, while water is injected via a plenum chamber through specialized nozzles to create an upward rising current. 这就建立了一个悬浮或摇摇欲坠的固体区域. The solids in suspension are of a size fraction at the point of separation (better described as the cut point), 悬空的:悬空时既不粗也不细的. Fine/light particulates don’t penetrate this dense fluidized bed and are carried up by the rising water current over the weir as overflow at the top of the unit. 较粗/较重的颗粒能够穿透摇摇欲坠的岩层, 由重力, pass through the water injection zone to be collected and discharged through an underflow valve.

The 菠菜网最稳定正规平台_最全菠菜网大全 Lites-Out™ maintains separation automatically through a simple PID control loop. Operators can set the water injection rate and the desired operating density. 这个单位需要最少的监督, as the Lites-Out™ control monitors the classification environment and opens/closes the dart valves at the bottom of the separation chamber. 该装置自动补偿进给量的变化, 唯一能动的是下流阀.

A manual globe valve and a flow meter is supplied with every unit so teeter water can be adjusted easily. 额外费用, the teeter water volume can also be automatically set and maintained using a separate PID loop control utilizing an air-operated control valve.

Where the Lites-Out™ units are being used for organics removal such as in soils washing or lignite removal, the overflow will contain larger organics with the finer sand (equivalent weight particulates); in this case, an interstage screen is used to separate the larger organics from the finer sands.

通常, 建筑集料, the screen throughs will be recombined with the coarse Underflow and fed to either 螺丝、水力旋流器和/或 脱水屏幕 生产可堆叠的菠菜网最稳定正规平台_最全菠菜网大全. 螺丝 and 水力旋流器s assist in further removal of the finest lightweight materials.

有机物或用工厂的废水处理, collected for use for site restoration or sent to high temperature destruction in the case of contaminated soils projects.
