Falling Stream Samplers are a general product category that covers a wide range of sampler designs. The key characteristic all these designs have in common is that sample material is collected from a main process flow that is either in a free-falling condition or traveling through some trajectory, 如在输送带的卸料处.

Falling Stream Samplers tend to be simpler in design and function, and usually offer highly reliable operation with relatively low maintenance requirements. This style of sampling is well suited to high flow rate applications where minimal downtime is a requirement, 比如装载系统.
使用落流采样器确实有一些限制. This type of sampler requires some amount of vertical clearance for installation (this height varies by machine type and application), 而且它们有时更具侵入性，安装起来也更昂贵. 落流采样器有许多应用. 菠菜网最稳定正规平台_最全菠菜网大全有一系列的菠菜网最稳定正规平台_最全菠菜网大全, as well as the ability to develop custom designed Falling Stream Samplers, 以满足您的具体需求.
落流采样器有各种各样的形状, 大小, 和配置, 但不管这台机器是什么, the basic function of this type of machine is essentially the same. 样品切割器停在移动物料流的一侧. 当要收集样本增量时, the cutter drive assembly (which varies by machine type) will move the cutter through the material flow at a constant speed, 收集样本增量.
对于分流型切割器(i.e. sample material is directed from the material flow to another area), the sample increment is directed into a sample discharge area of the sampler where it is either collected for offline use or passed into the next piece of equipment installed in the sampling system. 一旦刀具清除了物料流, the sampler drive stops the cutter on the opposite side of the material flow. The next increment is collected by moving the cutter back in the direction of the first parked position.
如果所讨论的取样器有一个底卸式刀具, the sample cutter will pass through the moving material flow at a constant speed, 在里面收集材料. 一旦刀具到达物料流的另一边, the cutter will open to release this material back into the main flow. 然后刀具将通过物料流返回, 收集样本增量, and stop back in its original parked position and empty the sample increment into a discharge chute. Material is then collected for offline use or directed to the next machine in the sampling system. It is also important to note that some bottom dump samplers may have a sample discharge point on both sides of the material flow. In this case, the operation would be as described with the diverter type cutter.
Falling Stream Sampler drive units vary by machine type but are usually one of three types of drives. 这些是齿轮减速器驱动的齿条和齿轮, 齿轮减速器驱动链条和链轮, 液压缸.
Regardless of cutter or drive type, the basic, simple operation and reliability remains the same.
菠菜网最稳定正规平台_最全菠菜网大全 offers many types of falling stream sampling equipment to cover the wide range of possible applications involving this style of machine. Some common types of Falling Stream Samplers for both dry materials and slurry applications are baffle plate type (in either vertical or tangential entry configurations), overhead carriage (with multiple cutter options like bottom dump and reverse spoon), 旅行料斗, Vezin，双维津，圆弧和其他，不太常见的类型. Falling Stream Samplers can easily be incorporated into new projects. 另外, 菠菜网最稳定正规平台_最全菠菜网大全提供的所有落流采样器都可以, 而且必须经常如此, 设计用于集成到现有操作中.
The basic design and simple back-and-forth mode of operation characteristic of Falling Stream Samplers limits the number of mechanical components. Limited components and simple operation allows for long service life and minimal maintenance. Maintenance that is eventually required is facilitated by appropriately sized and located access and inspection doors, 容易更换常见磨损物品(刀具唇), 滚轮轴承), and sealed-for-life bearings that eliminate the need for regularly accessing components.
不管你的申请要求是什么, 落流采样器是否适合您的应用, 麦克菠菜网最稳定正规平台_最全菠菜网大全有一个样品提供满足您的需求.
水平车厢底卸取样器 are one type of 落流采样系统. They feature a horizontal carriage arrangement in which the cutter is oriented to the side of the drive. The cutter moves with the drive from one end of the machine to the other through a falling stream of material, collecting a sample as it does so and depositing it via the bottom of the cutter.
Falling Stream Samplers can be widely applied throughout many industries, 包括煤, 可口可乐, 碎矿, 集中, 钾肥, 沙子, 石头, 砾石, 盐, 铝土矿, 木屑颗粒等.
