A mixer is a mechanical device that uses mechanical force and gravity to mix two or more materials evenly. During the mixing process, the contact surface area of the material can also be increased to promote chemical reactions; it can also accelerate physical changes.

Commonly used mixers are divided into four categories: gas and low viscosity liquid mixers, medium and high viscosity liquid and paste mixers, powder and granular solid material mixing machines.

Commonly used mixers are divided into four categories: gas and low viscosity liquid mixers, medium and high viscosity liquid and paste mixing machines, thermoplastic material mixers, powder and granular solid material mixing machines.

The gas and low-viscosity liquid mixer is characterized by a simple structure, no rotating parts, low maintenance and repair, and low energy consumption. This type of mixing machinery is divided into four types: air flow stirring, pipeline mixing, jet mixing and forced circulation mixing.

The mixer parts are mainly made of wear-resistant alloy materials, including high-speed mixing blades, mixing wings, wear-resistant liners, mixing arms, mixing shovel, planetary shovel, mixing coulters, mixing rods, mixing rakes, etc.

The mixing machinery of medium and high viscosity liquids and pastes generally has a strong shearing effect.

Thermoplastic material mixing machines are mainly used for mixing thermoplastic materials (such as rubber and plastics) with additives; powder and granular solid material mixing machines are mostly intermittent operations, and also include machines that have both mixing and grinding functions, such as roller mills.

The moving parts of the mechanical agitator will also produce a shearing effect on the liquid when rotating, and the liquid will also be subjected to shearing when flowing through the wall and various fixed components installed in the container. These shearing actions will cause many Local vortex diffusion.

For liquids with different densities, different compositions, and incompatible with each other, the shearing effect and strong turbulence caused by stirring will shatter the dense liquid into small droplets and evenly disperse them into the main liquid.

Common mixer types:

Common mixers include: coulter mixers, ribbon mixers, gravity-free mixers, V-shaped mixers, double-spiral conical mixers, high and low speed liquid mixers, planetary power mixers, etc.
