High speed disperser: Know the kind that is right for you

lab high speed disperser

Variable speed is available in terms of the disperser you are selecting. They come in single, two, and variable speeds of the mixing shafts. A few of the high speed disperser is generally fixed in terms of operations with the help of the blade in the only original position of mounting while a few are directly mounted on top of the tank. The blade is also lowered or even raised by several feet for better control over the vortex without having to exit the tank when it comes to the other kind dispersers that are tank-mounted.

Selecting the right size of the disperser

Horsepower is generally considered as the size of the disperser here. There is disperser out there that are quite large dimensionally but uses small amounts of horsepower relatively, and these are the general exceptions that are mentioned here.

The load that is anticipated for the blade will be creating at a proper speed along with the resistance in terms of the horsepower of the disperser here that is related to the blade here. The function of the rheology for the high speed dispersion mixer, along with the density and viscosity, is the resistance here. However, there is a significant rise in the horsepower disproportionately as the diameter of the blade increases.

With variable aspects here, the needs for horsepower are quite interrelated. In terms of the performance of the high speed disperser, there are exterior variations that are recommended in terms of the parameters for operating.

Selecting the right side of the tank

They are a bit taller than the width here, which is quite ideal for many of the dispersers out there. To prevent the solids from being accumulated in the corner edges being associated with the bottoms that are flat is helped through the bowl-shaped bottom. The integral part of the aspects out there has to be considered listed further here when it comes to the tank geometry at an optimum level.

Selecting the right size of the blade

Based on the characteristics of the flow with the product, here is the required degree of the dispersion, which determines the size of the blade for the high speed disperser. The diameter of the blade is greater when the product is thicker in comparison to the diameter of the tank. The diameter of the blade is smaller when the product is thinner compared to the diameter of the tank. Tank ratio is generally this comparison factor.

When do you need to replace the blade?

To reach out to the maximum point of the dispersion point should be ranging for about half an hour after the latter ingredients are added here once the formula for the batch has been processed for optimization. For getting the standard of the optimized dispersion, the blade starts to shear off when a greater amount of batch times are required here. Once you notice the blade tips are worn out of their original height, they should be replaced immediately.

Kind of blade required by your disperser

A myriad range of sizes and styles are in which the blades for the disperser are available. Open saw tooth and ring-type are the categories generally made. When they are used under the right operating conditions, both categories work really well.

Due to its lowered cost, general utility, and ease of cleaning, it is behind the popularity of these open saw tooth blades. A massive range of tooth designs is where it is available. The blade's pumping ability increases with the increase in the size of the teeth along with the rise of aggressiveness in its shape. The shear, therefore, decreases as the pumping or the turbulent flow increases. Compared to the lower shear paddle blade, the higher pump saw blades mainly generate significant shear of the high speed dispersion mixer. When you are determining what should be achieved of the end product, this is an aspect of vital consideration.

Factors that are affecting the performance of a disperser

The vital part of reaching out to the dispersion at an optimum level is the formulation for a disperser.

The changes to the basic recipe are not being accepted in terms of optimizing a formula that at times needs to do more with the way the ingredients are added to the high speed disperser. Greater addition of the total powders into the liquid car is accepted over various instances with observation done in careful nature for each initial formula which is prudent in terms of making sure the powders are not floating at the top of the batch for greater than a few seconds. It might be resulting in an incomplete, unstable dispersion with the addition of dry powders quite rapidly that can easily choke off the blade.

When the pattern of flow is in a manner of the shape of a doughnut, and the tips of the blades are traveling at around 4000 feet each minute in a viscosity that is of a medium nature is when dispersers work in a better way.  The speeds for the higher tip might be acceptable at the viscosities that are lower for getting the same rate of force along with the stress, while the speed of the lower tip might be accepted at the higher viscosities. The shear is considered as a function here for the tip of the blade and its speed along with the rheology of the product, in other words.

Operating disperser for optimum performances

The following are the criteria’s that are required for the optimum performances:

· Commence with a cleaner tank

· Right tank ratio to the blade

· Right kind of formulation

· Well-suited blade in the right condition

· The greatest level of tip speed for the blade in an appropriate level

· Right geometry of the tank

· Right horsepower

· The proper way to add the raw materials

· Right kind of rheology

Safety procedures to follow and why

The operational instructions and the safety measures supplied by the manufacturers should be read in the right manner. You can call up the manufacturers and also request them for additional copies if, by chance, they are not available on call.

One has to be quite certain for all the operators as they should be trained in a proper way in terms of the use along with drilled over the potential hazards that are involved with the dispersers here.

The disperser that is being manufactured by the suppliers like Franli is quite fast and powerful in nature. You can easily get hold of the efficient one and get your job done in the best way ever!
