Sampling unit, including sampling, etc., in charge of coal samples taken; in Line sample preparation unit includes feeder, crusher, riffle, coal receivers, abandoned like flowback equipment, some online sample preparation unit further includes a separator, Mixer, screening equipment and balers, will be responsible for preparing coal samples taken; controls the operating unit is responsible for coordinating the various components of the sampling machine, complete mining Sampling and sample preparation capabilities. Figure 1 is a phase of the online sample preparation sampler structure diagram, Figure 2 is a two-stage structural diagram of the online sample preparation sampler, in line with this Standard sampler other structures may also be used. 3.2 sampler type Sampler sampler coal flow into mobile and stationary coal sampler. Mobile coal flow down stream sampling includes sampling and sampling across the belt , Static coal samplers use more of a mechanical screw sampler. A typical example of the sampler shown in Appendix A, in line with the requirements of this Other types of samplers can also be used. 3.3 riffle type Riffle riffle stream comprising drop across the belt and riffle. A typical example riffle in Appendix B, in line with the requirements of this other
