Abstract:
1. A device for preparing a sample for continuous on-line analysis of finely divided, pulverized material, said device comprising: a sampler for diverting sample material of the finely divided, pulverized material from a material flow; a feeder element for discharging sample material in an essentially even fashion onto a conveyer element forming an essentially even bed of sample material on the conveyor element; the conveyer element for transporting the essentially even bed of sample material from the feeder element to an analyser; an analyser to analyse a surface layer of the bed of sample material; a smoothing element for contacting and smoothing out the surface layer of the essentially even sample material bed so that an essentially even sample material bed with a surface layer that has been smoothed out is transported past the analyzer; a measuring element for measuring the height of the sample material contained in said feeder element; and the partition element and the measuring element being interconnected to allow sample material to be sent to the feeder element if a level of material in the feeder element detected by the measuring element is below a predetermined value; and to further allow the sample material to be diverted back to a material flow if a level of material in the feeder element detected by the measuring element is above a predetermined value.
