Construction Of Turbine Mixer
The construction of a turbine mixer involves intricate engineering to achieve efficient mixing processes across various industries. Typically consisting of a robust frame, a drive system, and mixing elements, such as blades or impellers, turbine mixers are designed to agitate fluids or powders within tanks or vessels. The blades or impellers are strategically positioned to generate turbulence and promote thorough blending or dispersion of materials. Materials used in construction vary based on factors like operational environment and the properties of the substances being mixed, with options including stainless steel for its durability and resistance to corrosion, or specialized alloys for specific applications like high-temperature environments or corrosive chemicals. Precision engineering ensures optimal performance and reliability, with considerations for factors like speed, power consumption, and ease of maintenance. The design may also incorporate features for customization, such as interchangeable blades or adjustable speeds, to accommodate diverse mixing requirements. Through meticulous construction and innovative design, turbine mixers play a crucial role in enhancing efficiency and productivity across a spectrum of industrial processes, from pharmaceuticals to food processing, and chemical manufacturing to wastewater treatment.
The Turbine Mixer was Fabricated at the Mechanical Engineering Workshop of Institute of Management and Technology, Enugu.
The method of the fabrication of the turbine mixer involved a preliminary computation of the dimensions of the standard turbine in relation to the dimension of the reacting vessel in which they will be used in, making out, cutting out to sizes, rolling folding, welding, body – filling, filling, glass – papering and painting. The total surface area is 10741.5CM2
The first step taken in the fabrication of ht said project was the selection of the material suitable for the construction.
The materials used in the construction were locally sourced and were selected to suit the desired purpose. The mild steel was used instead of galvanized steel due to its relative low cost.
The mild steel was located with paint to prevent corrosion attack and deterioration of the work.
The dimensions of the project were as follow 31.0CM. for the height and –21.0cm for the diameter. The volume [capacity] of the cylinder is 10,74 1.5cm3 the average speed of the turbine mixer is 125pm. The turbine mixer is manually operated a design that is meant to save cost.

INTRODUCTION
The multiple of process and mechanical variable makes fluid agitation one of the most complete unit operations. For this reason the systematic studies of underlined me chemise of mixing operation progressed slowly, quantitative design data is spores and almost innumerable agitator configuration have evolved. Though often confused, agitation and mixing are not synonymous. Agitation refers to the induced motion of a material in a specified way, usually in a circulatory pattern inside some sort of container. Mixing is the random distribution into and through one another of two or more initially separate phases. Ex A single homogeneous material such as a thankful of cold water can be agitated, but it cannot be mixed until some other material is added such as powdered soerd.
However, many processing operations depend to their success on the effective agitation and mixing of fluids. To enhance these processing operation, Experimental agitators were developed to serve a wide variety of poetical and fundamental fluid mixing problem.
Experience has revealed that reaction that recurred mixing and agitation most often cannot perform without agitators. That is why the need to discuss agitators, Agitations and mixing can not be over ruled and has to be given to student in the territory institution as project work.
Mixing is been used to perperon on uniform combination of two or more substances. The material fed to a mixer could be gasses, higuidion solids. The product that is from mixer may be homogeneous or heterogeneous substance.
THE OBJECTIVE AND THE SCOPE OF THE PROJECT
Turbine mixer is one of the important equipment found in the chemical industries. It is been applied in variety of operations in the industries and homes such as mixing of solution of liquids, solids and gases.
The main objective of the project is to construct turbine mixer that will be widely versatile in application / operation.

Construction Of Turbine Mixer:
A turbine mixer, also known as a turbine agitator, is a type of industrial mixing equipment used in various processes such as chemical manufacturing, food production, and wastewater treatment. It consists of a rotating turbine or impeller that is submerged in a liquid or slurry to mix, blend, or agitate the contents. Here’s a general outline of how a turbine mixer is constructed:
Impeller or Turbine: The heart of a turbine mixer is the impeller or turbine. This is the rotating component responsible for creating fluid movement within the tank or vessel. Impellers come in various shapes and sizes, each designed for specific mixing purposes. Common types include flat-blade turbines, curved-blade turbines, and high-efficiency impellers.
Drive Mechanism: The impeller is connected to a drive mechanism, which provides the rotational motion. The drive mechanism can be powered by an electric motor, pneumatic system, hydraulic system, or even manual operation, depending on the application.
Shaft: The impeller is mounted on a shaft, which extends from the drive mechanism to the bottom of the tank or vessel. The shaft is typically made of stainless steel or another corrosion-resistant material.
Seals and Bearings: Seals are used to prevent leakage of the liquid or slurry into the drive mechanism. Bearings support the shaft and ensure smooth rotation. Proper seals and bearings are crucial to prevent contamination and ensure long-lasting performance.
Mounting Assembly: A mounting assembly is used to secure the turbine mixer to the top of the tank or vessel. This can include a flange or clamp system, depending on the specific design and installation requirements.
Speed and Control System: To achieve the desired mixing intensity and speed, a control system is often employed. This allows operators to adjust the rotation speed of the impeller to meet the mixing requirements of the process.
Materials of Construction: Turbine mixers are often constructed from materials that are compatible with the chemicals or materials being mixed. Stainless steel is a common choice due to its resistance to corrosion, but other materials like plastic or glass-reinforced materials may be used for specific applications.
Safety Features: Depending on the application, safety features such as overload protection, emergency stop buttons, and guarding may be incorporated to ensure the safe operation of the mixer.
Accessories: Depending on the specific application and industry, additional accessories such as temperature probes, pressure sensors, and sampling ports may be integrated into the mixer system for process monitoring and control.
Installation and Maintenance Considerations: Proper installation and routine maintenance are essential for the longevity and efficient operation of a turbine mixer. This includes regular inspection of seals, bearings, and the impeller, as well as lubrication and alignment checks.
The exact design and construction of a turbine mixer can vary widely depending on the intended application, scale of operation, and industry standards. Manufacturers often provide customization options to meet the specific needs of their customers.
