Sorting-detecting instrument and its detection method belong to metallurgy sintered, pelletizing industry raw material preparation field.
Background technique
In metallurgy sintered, pelletizing field, certain moisture generally is needed during mixing system material, it is necessary viscous to provide
Knot property and adhesive force are used for the formation of material pelletizing.These moisture include the portion of water that mineral aggregate itself contains, and are being mixed
Also the addition that moisture is had in process, mixes various raw materials uniformly, facilitates the balling-up and granulation of material, is conducive to subsequent work
It can more fully be reacted in sequence.Water is too low, and the caking property of raw material reduces, and will affect balling-up and the granulating properties of raw material.But
Raw materials for sintering moisture is excessively high, if concentrate powder is easy agglomerating viscous mine slot, influences the accuracy of ingredient, influences the uniformity of mixture,
Tail cross section of sintering machine, which generates paint face, influences the quality of sintering mineral products, also the energy consumption of agglomerates of sintered pellets technique can be made to mention when water is excessively high
It is high.To reduce energy consumption and making pellet forming process closer to optimum moisture content, the water content detection of raw mineral materials is very necessary.
Traditional sinter mixture detection uses oven drying method, offline inspection, but analysis time is long, can not reflect moisture in real time
The case where, lack the meaning for instructing technique to produce.Existing water content detection mostly uses NEUTRON METHOD, infra-red method or microwave method, these
Although method solves the problems, such as that analysis time long, can reflect current data, but NEUTRON METHOD has ionising radiation, existing in production
Field application is less；When appearance color, chemical component of infra-red method material etc. change, detection data just will appear larger inclined
Difference.For this reason, needing to carry out the calibration of water content detection parameter before use for every kind of material.For what is conveyed on a belt
The uncertain situation of material is difficult to realize the automatic survey water of different material, and needs manually according to the variation of material on belt
Situation adjusts the detection parameters of Moisture Meter, when material kind frequently variation, is then difficult to realize the on-line checking of moisture；Microwave method is not yet
It can accurately detect the moisture content of substance core.
The above method detection device and theoretical scheme are complicated, it is sometimes desirable to which professional just can solve.
