Some essential facts to uncover for high speed disperser


Horsepower is the term that is generally thought of in terms of the size of a disperser. However, there are dispersers out there that are quite large but uses quite lowered amounts of horsepower in them, and as a rule, these are the exceptions that are included here in terms of the high speed disperser.

The diameter of the blade and the load that is anticipated for the blade will be creating at a given speed, as well as the resistance in terms of the horsepower of the disperser here. The functional rheology of the dispersion along with the density as well as the viscosity here is considered as the resistance. The horsepower here disproportionately increases with the increase in the diameter of the blade there. The pumping will be greater considerably so that it would be lending itself in terms of working in a much larger tank and producing a greater amount of finished product in a similar period of time with the help of the blade of the high speed dispersion mixer.

There would be compromises in terms of the performance, including the bad particle separations, the extended dispersion times, along the decrease of the quality of the end product are the various recommended outside the parameters of operations.

Selecting the right size of the tank

Instead of being wider, the best tank for several of the dispersers here are a bit taller. The solids do not accumulate in the sharp edges that are associated with the flat side bottoms, which are generally dished or bowl-shaped here. There is also the ease of discharging along with cleaning in terms of flushing the bottom side of the valves that are welded onto the center of the high speed disperser. The important part of the several aspects that are required to be considered here is enlisted further onto the paper in terms of the optimum geometry of the tank here.

Selecting the right size of the blade

The size of the blade is dependent on the flow of characteristics of the products along with the desired degree of the high speed dispersion mixer. The diameter of the blade is greater compared to the thickness of the product in comparison to the diameter of the tank here. This is generally noted to be the tank ratio.

When do you replace the blade?

After the end ingredients have been thoroughly added to the high speed disperser, the process has been optimized in terms of the typical time that is needed in terms of reaching out to the maximum level of dispersion. In a few of the cases, things can get detrimental due to the higher batch temperatures that are generated by the higher shear disperser blades with the longer times that usually result in better dispersion methods here. To reach out to the dispersion standards here, the blade starts to disintegrate with a greater amount of batch timings that would be required here. Once the tips of the blades are worn to half their original height, the type of sawtooth blades needs to get replaced effectively.

Kind of blade that would work the best

In a varied range of styles and sizes, the high shear disperser blades are available greatly, and they are generally categorized into two groups significantly. One is the ring type, while the other is the open saw type. When these are used under the right conditions of operations is when they work great.

The highly popular ones are the ones with the lowered costs, ease of cleaning, along with general utility here in terms of the open saw tooth blades. There is always a massive range of designs for the tooth here. The teeth, however, become a lot more aggressive in their shape with the pumping ability of the blade that increases significantly. There is also a distinctive shear compared to lowered shear paddle for the blade agitator with a higher rate of pumping. It is the vital aspect of consideration in terms of determining what exactly needs to be achieved here as the end result.

Factors affecting the performance of disperser

The vital part of reaching out to the optimum level of dispersion is through the formulation.

You can have a lot more to do with the way the ingredients are added with the basic changes to the recipe that might not be acceptable here in terms of optimizing a formula. The rapid additions of the complete amount of powders into the liquid vehicle is surely acceptable here through the careful observation of every initial formula that is prudent for making sure that the powders are not staying afloat to the top of the batch for a massive period of time.

The high speed disperser here performs it best when there is a pattern in the flow of the shape of a doughnut with the tips of the blade traveling at a greater speed in minimum levels of viscosity. At the higher levels of viscosities here, the speed of the lower tips is quite acceptable, and this is the same in terms of the same rate of shear and the stress associated. The function here is mainly the shear in terms of the speed of the blade tip with the product rheologies.

The safety measures should be followed at all times

The instructions here are supplied by the manufacturers as you need to read them thoroughly. You can also call up the manufacturers in terms of requesting the copies.

Every operator here is trained in a proper way in terms of using the high speed disperser with the potential dangers involved with the same.

You should check out the relative safety features in terms of operating the machine and having them in a functioning way. The features here are included in terms of hoisting the mounted units by raising the lower blade, and they are not limited to the switches for lifting in terms of preventing the machine from operating with the shaft or the blade that can be reached well by the operator.

There are suppliers and manufacturers out there who are now manufacturing the high speed dispersers, among which Franli is the best company to go ahead with.
