Concrete mixer can be a variety of materials to fit into a uniform mixture, such as cement, sand and gravel mixed with water into concrete wet material, etc.;Also can increase the material contact surface area to promote chemical reaction;Can also accelerate the physical changes, such as granular solute solvent, added by the effect of mixer can accelerate sugar.

Commonly used cement mixer is divided into gas and low viscosity liquid mixing machine, high viscosity fluid and paste mixer, thermoplastic material mixing machine, powder and granular solid material mixer four categories.

1. The gas and the characteristics of low viscosity liquid mixing machine is simple in structure, and has no moving parts, less maintenance, low energy consumption.This type of mixer is divided into air stirring, pipe, jet mixing and forced circulation mix, etc.

2. Medium and high viscosity fluid and paste mixing machine, planetary mixer, dual planetary mixer, planetary mixer, double planetary double power mixing machine, multi-function mixer, this kind of mixer in general has strong shearing action;

3. The thermoplastic material mixer (kneading machine) is mainly used for thermoplastic materials (such as rubber and plastic) mixed with additives.Typical equipment: kneading machine, ordinary kneading machine, vacuum kneading machine, high temperature kneading machine, screw extrusion type kneading machine, silicone rubber kneading machine.
