Riffle Splitters are the most common sample divider, with an efficient design that directs materials through an array of chutes. Fractions are discharged into separate collection containers. spinning rifflers, or rotary sample dividers, are the method of choice for precision representative sampling of the highest order.
Sample Double Roll Crushers and MiniSizers are simply smallerscale versions of the Double Roll Crusher and Direct Drive Crusher (DDC) product groups for which McLanahan has become well known. These machines retain the key features and benefits of the larger machine designs but are packaged into compact, costeffective solutions specifically tailored to reliably and efficiently handle lower ...
Isokinetic sampling is widely used in dust and particle measurements in power plants, furnaces, kilns, and scrubbers. Ambient air pollution measurements also make use of this method. Other applications in coalfired power plants include sampling of pulverized coal and sampling steam to check the purity before in enters the turbine.
The coal flow, moisture variations and other conditions that can have an effect . on the coal stream or coal characteristics must be reviewed. The number of seams, coal types or blends to be used in the test must be established, and the widest range of ash and sulphur values must be selected. The mechanical sampling system should be inspected
perpendicular to the coal flow. It cuts a swath through the coal and throws a sample into a chute. The. coal sample is taken via the chute to the analysis equipment. The high inertia scoop must be accelerated. to full speed within 90 degrees rotation to insure it will have enough power to cut through the coal as it. travels along the conveyor belt.
Automatic Sampling Automate the collection of samples that represent the process stream accurately and efficiently using controllers. From industrial, food grade, hygienic to 3A standards, our automatic samplers remove human bias to collect representative samples for liquid, slurry, powder or solid sampling applications.
