Equipment For Agitation What is agitation? Agitation is a process of mechanical forcing a fluid to flow in a specific pattern inside a vessel. The agitation and mixing process is a vital part of many processing industries to a great extent and it is done with specific agitation equipment. Agitators are most efficient for mixing liquids with liquids and liquids with gases, although it is quite efficient for many other mixing processes also.
Viscosity â€“ Main Factor When Choosing An Agitator When choosing an agitator for specific applications, the viscosity of fluids may be the most important factor. To choose the right one, you may want to consider an agitator with high viscosity and reduced discharge of volatile organic products. But you need to know that the viscosity directly impacts the flow and the operation of the agitator, so a limitation must be set.
Other Important Factors Flow - The mixing processes demand of the agitators to secure a constant flow of material through the mixing vessel. A constant flow helps the agitators to get a complete batch turnover and increase the level of homogeneity. Also, it helps in preventing excessive heat by the high-shear agitators. So, a small improvement in the flow can be important, as it may open a possibility for greater shear, which can result in shorten efficiency of the agitators. Shear - The shear of agitators is another important factor that needs to be considered before making a purchase. Many mixing operations today follow the rule of thumb: apply as much shear as possible. When a great circulation in the vessel and a fast cycle are stimulated, you can increase the per-batch production.
Types Of Agitators The agitation process dissolves solids from liquids, blends two miscible liquids and distributes various gases in liquids in form of bubbles. Although all agitators have a same working principle, today there is a wide choice of agitators for sale. Go on through this presentation and find out the three most common types of agitators for sale.
Three-Blade Impeller Agitator The three-blade impeller agitator is one of the most common agitators and is usually utilized in driving boats. Its impeller (shown on the picture below) is mounted on the side or fixed on the side of an open vessel.
This type of agitator (show on the picture above) is capable of operating at exceptionally high speeds and reach to 1800 revolutions per minute. So, the three-blade impeller agitator is ideal for low-viscosity liquids.
Paddle Agitator The paddle agitator is also a common agitator, especially for low-speed applications that do not require more than 200 revolutions per minute. Usually, the paddle agitators include two and four-bladed flat paddles. The paddle agitators have a great radial flow, but they are lacking of vertical and axial flow, which means that they are not very efficient in suspending solids as liquids.
So, it is evident that the paddle agitators are most efficient for viscous liquids. Processing paints, cosmetics and starch pastes are some of the most common applications of the paddle agitators. There are many agitators for sale online and if you are looking for one, visit www.machines4u.com.au and check its comprehensive range of agitators.
Turbine Agitator A turbine agitator is a unique combination of multi-bladed paddle agitators and shorted blades, efficient for a variety of applications that demand high speeds. In fact, it is extremely efficient for mixing liquids of any viscosity at high speeds.
Usually with 4 to 6 blades, the turbine agitators provide a great radial flow and are good gas dispersers. A turbine agitator with 4 blades is most efficient for suspending loads, while a three-blade impeller agitator has a greater pitch angle and allows more fluid motion and mixing power.
