Selection of Batch and Continuous Mixers

As mentioned earlier, it is best practice to sample a mixer at the discharge location. A number of online samplers are available in the market whole stream samplers, cross-cut samplers, and split-stream samplers. The following factors must be considered for selection of an appropriate sampling device  

Flowability of the material (cohesive versus free-flowing). The sample must be capable of flowing into the sampler. 

Maximum particle size. The sampler must be sufficiently large to accommodate the maximum particle size. 

Friability of the material. The sample must not be crushed in the sampler. 

Size of sample desired. The sample size should match its intended use.
