Working Principle of Tank Mixer

The working principle of a tank mixer involves a systematic approach to effectively blend and homogenize the contents within a storage tank. The core components include a motor-driven mechanism and a mixing element, typically an impeller or agitator, submerged in the tank's liquid content. When operational, the motor supplies power to rotate the impeller or agitator at a predetermined speed. The impeller's design determines the flow pattern it creates within the tank. For instance, axial flow impellers induce a horizontal flow pattern, radial flow impellers create a vertical circulation, and pitched blade turbines provide a more turbulent and omnidirectional mixing action. The rotating impeller generates a series of vortices and currents which force the liquid to move throughout the tank volume. This continuous motion ensures that any settled solids are suspended and mixed evenly into the liquid. In cases where multiple phases are present (e.g., solid particles in a liquid suspension), the mixer helps prevent settling by keeping the mixture homogeneous. In essence, tank mixers work by converting the mechanical energy from the motor into fluid motion, promoting efficient blending and reaction kinetics, and maintaining product consistency over time. Depending on the application, they can be adjusted to achieve gentle mixing or powerful agitation to break down lumps or disperse substances thoroughly. image of tank mixer - SeFluid

Types of Tank Mixer

Tank mixers come in various types to address different mixing requirements across a wide range of industries. Here are some common types:

Propeller Mixers: These use a propeller-style impeller to create a rotational flow pattern, suitable for low to medium viscosity fluids. Propeller mixers can generate either laminar or turbulent flows depending on the pitch and diameter of the blades.
Paddle Mixers: Ideal for viscous products and dry bulk solids, paddle mixers use flat, broad blades to push and fold the materials. They are often used for blending powders, granules, or pastes.
Agitators: Agitators have several types of impellers, including turbine, anchor, helical ribbon, or pitched blade turbine. Turbine agitators generate high shear forces and are used for rapid blending, while anchor agitators create slow-moving, vertical currents ideal for suspending solids in liquids.
Static Mixers: Unlike dynamic mixers, static mixers don't rely on moving parts. Instead, they use a sequence of stationary elements within the tank to split, redirect, and recombine the flow streams for thorough mixing.
Jet Mixers: These mixers utilize high-velocity fluid jets to induce mixing. By injecting pressurized liquid into the tank, they create intense turbulence and promote rapid blending.
Magnetic Stirrers: Mainly used in laboratory settings, these mixers have a magnetic field generated outside the tank that rotates a magnetic stir bar inside, stirring the liquid contents.
Emulsifying Mixers: Specialized mixers designed for emulsions or dispersions feature high-shear mixing heads that can break down droplets or particles to extremely small sizes.

Each type of tank mixer is engineered to optimize specific mixing tasks, taking into account factors such as tank size, fluid properties, desired mixing intensity, and the nature of the process itself.

Fine Impact Mill

Fine impact mill is a type of machines used for superfine powder production. SeFluid has rich experience on producing various type impact mills.

Introduction of Fine Impact Mill

A fine impact mill is a machine designed for reducing particle size by utilizing the impact of high-speed rotating hammers or pins. The mill consists of a grinding chamber, a rotor, and a classifier. The material to be processed enters the grinding chamber and is subjected to the force of impact between the hammers and the particles. As a result, the material is pulverized into fine particles of consistent size and shape. This SeFluid's superfine powder mill series is composed of crushing host, cyclone separator, pulse dust box and centrifugal fan. It is suitable for processing a variety of materials, and the particle size is adjustable without machine stopping. The output particle size is uniform with fineness up to 10-5 um. fine impact mill 2 | SeFluid

Principle of Fine Impact Mill

The working principle of an fine impact mill is based on the collision between the incoming feed material and the rotating impellers or hammers. When it works, the feed material is introduced into the grinding chamber of the impact mill through a feed chute or hopper. As the material enters the grinding chamber, it is struck by the rapidly rotating impellers or hammers. The impact force generated by the impellers or hammers causes the material to break into smaller pieces and particles. The size of the particles produced by the fine impact mill can be controlled by adjusting the speed of the impellers or hammers, the size and shape of the grinding chamber, and the size and shape of the feed material. There is a series of steps that result in the reduction of particle size. Here’s a breakdown of the working principle:

Material Introduction

The material to be processed is introduced into the grinding chamber of the machine. This can be done through a hopper or a feed mechanism, depending on the specific design of the mill.

Impact Zone

Once inside the grinding chamber, the material comes into contact with the high-speed rotating hammers or pins. These hammers or pins are typically attached to a rotating rotor, which generates the necessary impact force.

Impact and Fragmentation

As the rotor spins rapidly, the hammers or pins strike the material with significant force. This impact causes the material to break apart into smaller particles. The energy from the impact is transferred to the particles, leading to fragmentation and pulverization.

Classification

After the initial impact, the resulting particles continue to move within the grinding chamber. In many impact mills, there is a built-in classifier mechanism that separates the finer particles from the larger ones. This classifier may be a static screen or a dynamic air classifier, depending on the mill design.

Fine Particle Collection

The finer particles, which have reached the desired particle size, pass through the classifier and are collected in a separate collection chamber or container. These particles are typically the product of interest and are often used in further processing or packaging.

Oversize Particle Re-circulation

The larger particles that do not pass through the classifier are directed back into the grinding chamber for further impact and size reduction. This re-circulation process continues until the desired particle size distribution is achieved. The specific design and configuration of fine impact mills can vary. Some mills may have multiple stages of impact, where the material undergoes several rounds of impact and classification for further refinement. Additionally, the material being processed can also impact the design of the mill, as different materials may require specific rotor configurations, hammers, or pins to achieve optimal grinding performance.

Advantages of Fine Impact Mill

Fine impact mills have a wide range of applications in various industries, including:

Efficient Grinding
