Vibrating Viscometer For Raw Slurry Used in Wet-Process Cement Plants

1. If the viscosity of raw materials such as limestone and clay in the original slurry is abnormal, it will cause stratification and precipitation of the original slurry, resulting in uneven chemical composition of the raw materials entering the kiln, resulting in substandard clinker strength and inconsistent quality.

2. The original slurry needs to be continuously transported to the kiln through pipelines. Too high a viscosity will lead to poor fluidity, increase the load on the delivery pump, and even block the pipeline and wear the pump impeller. Low viscosity will cause slurry precipitation, affect the transportation stability, and increase equipment maintenance costs.

3. The energy consumption of wet cement calcination accounts for a high proportion of the production cost. If the viscosity of the original slurry is too high, it will be difficult for water to evaporate, which will cause the kiln temperature to fluctuate, which will not only reduce the output, but also significantly increase the consumption of coal and other fuels. Stable viscosity can ensure stable working conditions of the preheater and kiln, achieving energy saving and consumption reduction.

4. Manual sampling tests have hysteresis and cannot reflect changes in viscosity of the original pulp in real time, which can easily lead to untimely process adjustments.

The working conditions of cement slurry include solid particles, low to medium viscosity, continuous transportation, large dust, and strong vibration.

Compared with other types of viscometers, rotational viscometers have movable parts that are easily stuck and worn by particles, leading to measurement failure; capillary viscometers are prone to clogging and cannot be adapted to continuous online monitoring. The online vibration viscometer does not have any movable parts, so the probe rod is not easy to hang materials and is not easy to cause blockage.

The online vibration viscometer can be installed directly on the pipeline or tank to achieve 24-hour continuous measurement and real-time data output, making up for the shortcomings of manual sampling lag. This is also the core reason why customers abandon laboratory sampling methods and choose online equipment.

The wet cement plant has a lot of on-site dust, strong equipment vibration, and there is a certain risk of flammable gases. The online vibration viscometer has excellent anti-vibration and anti-dust capabilities. It can be customized with an explosion-proof structure and can operate stably for a long time in harsh environments without frequent maintenance.

Compared with other types of online viscometer, it has low maintenance cost, long service life and higher cost performance.
