The pump has all of the benefits of standard horizontal centrifugal slurry pumps, such as durable wear flow parts, suitable construction for working conditions, good performance for solid handling, and so on. Still, it is also a submersible slurry pump, so it has the benefits of a submersible pump. It might function as a dredge pump with its agitator. The agitator is constructed with a motor and a high chromium impeller cutter. The high chromium agitator impeller allows it to cleave hard rock underwater.
What is a Slurry Agitator Pump?
Slurry pump agitators apply kinetic energy (motion energy) to solids near the pump input, resuspending them into a fluid state that would otherwise have buried and starved the system of liquid. The fine particles are sucked into the submersible slurry pump and discharged through the discharge, providing an accurate and slurry-free intake. Flotation mechanisms and attachments, such as an electric hoist, floating discharge piping, control panels, a traverse winch, and a high-pressured jet ring, are included with slurry agitator pumps.
The slurry agitator pump is divided by product type, design, application, distribution channel, and region. The slurry agitator pump market is divided into centrifugal and positive displacement pumps based on product type. The market is divided into three categories according to design: horizontal, vertical, and submersible.
What is the Role of a Slurry Agitator Pump?
Because water always travels along the path of least resistance, a pump without mechanical agitation will merely pump water, leaving particles to build around the pump intake. Agitator pumps provide kinetic energy (motion energy) to the slurry solids surrounding the pump intake, resuspending them into a fluid condition. These otherwise buried materials are drawn into the pump and pushed through the discharge, keeping the information clear and free of slurry accumulation.
This machine is also used in industrial plants to remove filer media. Emerging slurry agitator pumps with improved, innovative design, technology, and the capacity to perform several duties in mining, industrial, and power plants are predicted to stay appealing to end customers. This has recently increased the global demand for slurry agitator pumps.
Agitators can work with liquid, gaseous, and solid media (granules, powders, etc.).Slurries, suspensions, and very viscous liquids are also acceptable. However, selecting the appropriate agitator type, size, and design for the medium’s unique nature is crucial. Viscosity and susceptibility to shear stress are important factors when choosing an agitator. Agitators come in a variety of shapes and sizes.
Application of Slurry Agitator Pump
Slurry agitator pump applications include power generation, wastewater treatment, mining, mineral processing, coal-fired power plants, construction, oil & gas, iron and steel, pulp & paper, and others. The worldwide slurry agitator pump market is divided into two distribution channels: online and offline. The online channel is divided into e-commerce sites and company websites. Specialty stores, manufacturer outlets, and independent stores comprise the offline channel.
Agitators can perform a variety of tasks in any industrial plant, including:
- To create a consistent consistency, homogenize solutions and suspensions.
- Keeping liquids mixing and minimizing concentration gradients
- Introducing gas into a liquid solution
- Increasing the rate of a chemical reaction within a reactor
- Keeping the temperature of a solution inside a vessel constant
- Increasing heat transmission in a jacket
Features of a Slurry Agitator
Agitators are made up of three essential parts:
The motor powers the agitator component. It generates the necessary torque to induce regulated flow and shear in the fluid. The energy required by an agitator is determined by a variety of factors, including:
- The viscosity, specific gravity, and solid content
- Impeller rotational speed (rpm)
- diameter of the impeller
- The impeller’s power number
- Count of impellers
The shaft connects the torque of the propeller to the impeller. Couplings, end caps, and other devices are used in the shaft assembly. Sealings are also used to prevent material accumulation.
The impeller is the essential element of an agitator because it influences fluid motion, incorporating efficiency and mixing qualities. Its job is to direct energy to the materials being combined. It generates fluid flow and shear patterns as it rotates. This is the order of the actual mixing.
- For industrial, mining, milling, power plants, water treatment, sewage, organic waste, and other applications where slurry solids tend to build.
- Pump higher concentrations and volumes of sediment.
- Long-term wear and abrasion resistance.
- Suitable for use with any of our flotation platforms.
Types of an Agitator
Based on impeller design, the main types of agitators are:
Agitators with Coil Impellers
Spring-loaded coil impellers serve as impeller blades. They generally produce a radial flow pattern. The mechanical stiffness surpasses the resistance provided by the solids at the bottom of a suspension during mixing. These impellers also keep solids from settling at the tank’s bottom.
Agitators with Dispersion Blade Impellers
Dispersion blade impellers are made out of a disc with sharp outer blades or teeth on its corners that shatter down solid and sluggish liquid agglomerations into small particles. In industry, sawtooth design is standard. Because of interaction with the media, the outer blades sharpen with usage. Extreme dispersion and unstable flow are achieved by operating these impellers at high speeds. Hard metals like carbide and stainless steel are commonly used to make dispersion blade impellers. In solid-liquid or liquid-liquid dispersion, dispersion blade impellers are often utilized. They are employed in the dispersal of pigments in a viscous paint composition. They are also used for emulsification and grinding.
Hydrofoil Impellers with Agitators
Two to four narrow tapered and cambered blades make up a hydrofoil impeller. In industry, the three-blade arrangement is the most popular. From the tip to the hub, the blade angle rises. These impellers produce axial flow patterns. Hydrofoil impellers are more efficient than pitched blade impellers because they increase fluid flow while creating a low shear rate and consuming the least. Hydrofoil impellers are more cost-effective when employed in big-diameter tanks than propellers.
In devices for low-viscosity fluid mixing, suspension, and flocculation, they are also beneficial in shear-sensitive environments such as high-biomass slurry.
WIDE-BLADE hydrofoil impellers
When compared to normal hydrofoils, they have a higher solidity ratio. The solidarity ratio is the ratio of the overall blade area to the size of the circle encircling the impeller. Size hydrofoil impellers are ideal for gas-liquid dispersions due to their large contacting size. These impellers demand more power than standard hydrofoil impellers. A pitched blade impeller, on the other hand, requires more energy.
Retreat curve impellers primarily produce radial flow; axial flow is determined by the diameter ratio and the impeller’s height from the tank bottom.
To achieve uniform dispersion, retreat curve impellers are employed in solid-liquid and slurry media. Because the rounded edges reduce turbulence and generate low shear, they are appropriate for shear-sensitive media. These impellers usually run at modest speeds.
Agitators With Screw Impellers
Screw impellers with a spiral flight directly linked to the impeller shaft. They have a high top-to-bottom turnover. They are used to combine viscous and shear-sensitive media.
Anchor agitators have impellers that are shaped like anchors. They usually are U-shaped to follow the curvature of the tank. They produce primarily tangential flow patterns. However, angled blades on horizontal supports can create axial flow.
Anchor agitators are used to combine and transferring heat from excessively viscous liquids. Because their impellers provide a smooth low-shear flow, they are employed to mix shear-sensitive media. Anchor agitators are the most cost-effective laminar flow agitators. They work well in tanks with rounded or conical bottoms. The impeller can be built with a low clearance to the tank wall.
Double Helical Ribbon Agitators
These impellers, the best high Visco high-viscosity low impeller, are also employed in heat transfer applications. The impeller can also be built with a low clearance to the tank wall.
Helical Ribbon Agitators
A helical impeller blade is fixed in the shaft of a helical ribbon agitator by rods. These impellers can provide laminar flow as an alternative to anchor impellers. These agitators create an axial flow pattern. They feature a larger fluid contact area and may mix fluids with higher viscosities.
Paddle agitators have two flat paddle-shaped impeller blades that extend all the way to the tank walls. They are employed when there is no need for substantial axial and radial flow. These impellers are utilized for low crystallization, dissolution, and heat transfer and can produce a laminar low-shear flow. They typically operate at low speeds and create tangential flow patterns. Secondary blades can be added to the paddle blades to improve the mixing of more dense materials.
Propeller agitators primarily generate axial flow. However, tangential flow can also be produced. After the impeller blades pull the fluid, it is transferred and propelled lengthwise. The tilt of the impeller blades determines the fluid deflection. The impeller blades are tapered toward the shaft to reduce centrifugal force while increasing axial flow.
Agitators vs. Mixers
Although “agitators” and “mixers” are sometimes used similarly, they do not strictly signify the same thing. Mixers are pieces of machinery that quickly combine two or more components. When a member enters a mixer, it is frequently “pure” and departs mixed with other features. Agitators, on the other hand, preserve homogeneity and balance in an existing mixture.
Agitators are equipment components that create flow and shear in a fluid or substance, causing the fluid to homogenize. The flow pattern produced by agitator impellers can be used to classify them. There are three types of flow patterns: axial, radial, and tangential.
