What is Paddle Mixer?

The paddle mixer is a commonly used mixing equipment used to uniformly mix different materials. It consists of one or more paddles fixed on a rotating shaft. When the mixer is started, the paddle rotates in the container and pushes the materials in different directions to achieve mixing of the materials. Paddle mixers are suitable for mixing solid, powder and granular materials.

Paddle mixers play an important role in many fields, such as the mixing of pigments, dyes and additives in the chemical industry, the mixing of pharmaceutical powders and excipients in the pharmaceutical industry, the mixing of powders and granules in the food industry, etc. It can improve production efficiency, ensure product quality, and meet the needs of different industries for mixed materials.

Common Types and Applications

Straight blade

The straight blade is the most common type of blade. It usually consists of several straight blades and is installed on the shaft of the mixer. The straight blade can provide high mixing intensity and shearing force, and is suitable for materials that require strong mixing effect.

Inclined paddle

The paddle of the inclined paddle is installed on the shaft at an oblique angle, which can generate strong eddy current and shearing force, and is suitable for materials that require strong shearing and mixing effects.

Curved Blade

A curved blade has a curved blade, usually with a larger area and smaller angle. The curved blade can provide a larger mixing area and lower mixing shear force, and is suitable for materials that require a gentle mixing effect.

Propeller blades

The propeller blades are in a spiral shape and can generate strong eddy currents and shearing forces. They are suitable for materials that require strong shearing and stirring effects.

Special blades

According to different mixing requirements, some special-shaped blades, such as scraper blades, anchor blades, etc., can also be designed and manufactured to meet the mixing requirements of specific materials.

How does a paddle mixer work?

The paddle mixer mixes the materials through the rotation of the paddles. When working, the material is put into the mixing chamber, and then the motor is started to drive the paddle to rotate. The rotation of the paddle generates powerful stirring and shearing forces, causing the materials to be continuously cut, folded and mixed. At the same time, the rotation of the blades will also cause convection and turbulence effects, promoting uniform mixing of materials. During the mixing process, the paddle speed and mixing time can be adjusted as needed to achieve the desired mixing effect. Finally, the mixed materials can be taken out from the discharge port. The working principle of the paddle mixer is simple and effective, and it is suitable for material mixing needs in various fields.

Paddle mixer composition and structure

The paddle mixer consists of a mixing chamber, paddles, motor, support structure and control system. The mixing chamber is a space that accommodates the mixing of materials. The paddles are rotated by a motor, the support structure is used to support the equipment, and the control system is used to control the mixing process. These components work together to achieve uniform mixing of materials.

Mixing chamber: The mixing chamber is the space where materials are mixed. It is usually a cylindrical or elliptical cylindrical container with an inlet and outlet.

Paddle: The paddle is the core component of the paddle mixer. They are located in the mixing chamber and rotated by a motor. Blades can come in different shapes and numbers, with flat blades and curved blades being common.

Motor: The motor provides power to drive the rotation of the blades. An electric motor is usually used to drive the paddle mixer, and the power and speed of the motor can be selected according to the mixing needs.

Support structure: The support structure is used to support the mixing chamber and paddles to ensure the stability and safety of the equipment.

Control system: The control system is used to control parameters such as start and stop, speed, and running time of the paddle mixer to achieve precise control of the mixing process.

Benefits of paddle mixer

Uniform mixing

Through the rotation of the paddle, the materials are ensured to be evenly mixed to avoid unevenness.

Efficiency

Mix materials quickly, improve production efficiency, and shorten production cycle.

Wide applicability

It is suitable for mixing granular or powdery materials and can meet the needs of food, chemical, pharmaceutical and other industries.

Easy operation

It is easy to operate, easy to control and adjust the mixing process, and reduces the difficulty of operation.

Saving energy

Optimizing design saves energy consumption, reduces production costs, and improves economic benefits.

Easy maintenance

The equipment has a simple structure and is easy to clean and maintain, extending the service life of the equipment and reducing maintenance costs.

What is the difference between single-shaft blades and twin-shaft blades?

Single-shaft blades and double-shaft blades are two common structural forms in paddle mixers:

Single-shaft blade: A single-shaft blade mixer has only one main shaft, with paddles installed on the main shaft, and the paddles rotate around the main shaft for mixing.

Dual-shaft blades: Dual-shaft blade mixers have two shafts, each with paddles installed on them. The paddles rotate around their respective axes to improve the mixing effect and speed.

Compared with the single-shaft blade mixer, the twin-shaft blade mixer has a more uniform mixing effect and a faster mixing speed. It is suitable for occasions that require higher mixing effects.

Model selection

Paddle mixers are a commonly used mixing equipment that come in a variety of design and configuration options. Here are some common design elements:

Material selection: The materials of the paddle mixer can be carbon steel, manganese steel, 304 stainless steel, 316L stainless steel, 321 stainless steel, etc. According to needs, the parts in contact with the raw materials and the parts not in contact with the raw materials can be made of a combination of different materials. The surface treatment of stainless steel includes sandblasting, brushing, polishing and mirror polishing, etc., which can be used in different parts of the paddle mixer.

Drive unit: The drive device, power and speed vary according to the raw materials, starting method and processing technology. Dual-axis drive devices require synchronization capabilities, and the four different drive combinations launched by Shengli Company can meet different requirements, including two synchronous gearboxes, dual output gearboxes, dual synchronous planetary gearboxes, and combinations of reducers and chains. Among them, the SK series double synchronous gearbox is the best configuration for the double-shaft paddle mixer.

Stirring device: According to the nature of the raw materials, the paddles can be adjusted and designed accordingly. For example, wear plates, Teflon plates, or serrated paddles can be added. The twin-shaft paddle mixer can also add high-speed breaking rods inside the container to scatter the flowing material.

Discharging device: The standard discharging device of the double-shaft paddle mixer is a double pneumatic flat flap valve. When the valve is closed, the flat flap fits perfectly with the mixing barrel to avoid mixing dead zones, thus improving the mixing effect.
