螺旋钻取样系统

螺旋钻取样系统是如何工作的

An auger is a vertically oriented section of spiral flighting that rotates within a section of pipe. The bottom end of the flighting projects out of the tube slightly and has a wear-resistant cutting head that loosens material to be sampled and directs it up into the bottom of the auger tube. Sample material then travels up the auger tube until it reaches the top. 如果要收集完整的螺旋钻增量, the material is diverted from the top of the auger tube into a sample collection hopper, 哪个安装在螺旋钻的侧面. 如果螺杆增量是分开的, the material passes from the top of the auger tube and through a fixed splitter, where the reject portion falls back into the material being sampled. 保存部分收集在螺旋钻样品漏斗中.

Once an auger increment is collected in the auger sample hopper, 螺旋钻被移动到样品接收漏斗上. This receiving hopper is either the point at which final sample collection occurs or it acts as the entry point to any subsequent sample processing equipment incorporated into the system. The orientation of the remaining portion of the system varies by application but generally will include secondary (and possibly tertiary) sampling and rejects handling. Sample crushing is also sometimes included depending on the application.

经常处理的散装物料包括煤, 可口可乐, 粉碎矿石, 金属和非金属精矿, 盐, 钾肥, 木屑颗粒及其他干散物料.

In an ideal situation, bulk materials are mechanically sampled from a moving material flow. Examples of ideal sampling locations include on a moving belt conveyor, 在垂直滑道中自由落体, or as material is discharged from a conveyor at a transfer point. In actuality, however, this is not always possible and other means of sample collection must be used. The most common example of this situation is where material to be sampled is confined in some type of container for transportation purposes.

散装物料经常用卡车运输, 铁路, 或者其他容器, and often there is no other option for sampling other than to collect samples from the transport container, 特别是在发货和收货情况下. These are the types of applications to which auger sampling systems are well suited.

菠菜网最稳定正规平台_最全菠菜网大全 offers a wide range of Auger 抽样 options from basic, manually operated primary auger sampler station to more fully automated multi-stage systems. The key components that distinguish these types of systems from other sampling systems are the auger itself and the device used to maneuver the auger. 菠菜网最稳定正规平台_最全菠菜网大全提供三种标准尺寸的螺旋钻, 12” (305mm), 20 " (510mm)及24 " (610mm), 所有这些都满足了大多数常见应用程序的需求. 螺旋钻可以保留完整的螺旋钻增量, 但它们也可与整体样品分离器. These sample splitters can reduce the total amount of material collected by the auger by predefined ratios, 通常是6:1或4:1, 但实际比例可以根据应用定制. 螺旋钻机动选项包括基本的垂直螺旋钻运动, 手动控制液压起重机, 部分运动螺旋龙门架, 和全运动螺旋龙门架. Augers and auger sampling systems can also be designed as permanent stationary  systems or semi-portable units that can be partially disassembled and relocated.

Once primary sample increments are collected by the primary auger sampler, processing those increments is the same as any number of other multi-stage sampling systems for which 菠菜网最稳定正规平台_最全菠菜网大全 has become well-known. What makes auger systems unique is that they are nearly always customized in some way to meet a client’s application requirements. Tailoring sampling solutions and customizing system layouts and equipment to meet a client’s specific needs is an area in which 菠菜网最稳定正规平台_最全菠菜网大全 excels.
