SCHLIENGEN – Baffle plates for continuous measurement of bulk flow rates are used in many plants, where solids are handled in the processes. That mechanical technique offers a lot of advantages compared to partial weighing of bulk solids because no more material has to be taken out of the process.
Nevertheless, baffle plates entail some disadvantages, especially during the installation. Those disadvantages are eliminated with the MaxxFlow HTC as a system for the solid flow metering.
In principle, MaxxFlow HTC can be used in all areas, where large volumes of bulk material have to be measured after mechanical conveyor organs, such as spiral conveyors, rotary conveyors or similar mechanical discharge organs. An upper limit for the throughput does not exist. Any material volume can be measured – regardless of hourly performance amounts of 50, 180, 290 t/h or more.
The previous disadvantages like installation height or necessary modification measures for mechanical methods like baffle plates or measurement chutes are not relevant anymore. The installation height of the sensor element amounts only 300 mm and the installation position is completely arbitrary. That is why retrofitting in existing systems is easy.
The MaxxFlow HTC system is consequently the optimized measurement technology compared to the traditional baffle plate or other mechanical techniques for measurement in great mass flows (> 20 t/h).
Even the material, whether raw mix, cement, plaster, salt, gravel, doesn’t matter for the measurement, because it is equally independent of the flow rate as well as of the flow pattern of the conveyed material in the line.
Among other places, the MaxxFlow HTC is used in several cement plants in which the measurement of the cement volume is used as a reference input variable for the iron (II) sulphate addition. In additional applications, also in the cement area, the raw mix volume is recorded. This makes it possible to ensure the required mix ratios and thus provide an output of constant quality.
