Mixer material machine

The color mixer is a machine that uses mechanical force and gravity to evenly mix two or more materials. Color mixing machines are widely used in various industries and daily life.



The color mixer can mix a variety of materials into a uniform mixture, such as cement, sand, crushed stone and water into wet concrete; It can also increase the contact surface area of materials to promote chemical reaction; It can also accelerate physical changes, such as adding solvent to granular solute, and accelerating dissolution and mixing through the action of mixing machinery.



Commonly used color mixers are divided into four categories: gas and low-viscosity liquid mixers, medium-high viscosity liquid and paste mixing machines, thermoplastic material mixers, and powder and granular solid material mixing machines. The gas and low viscosity liquid color mixing machine is characterized by simple structure, no rotating parts, small maintenance and low energy consumption. This type of mixing machinery is divided into four types: air flow mixing, pipe mixing, jet mixing and forced circulation mixing.



The color mixing machine of medium and high viscosity liquid and paste generally has strong shearing effect; Thermoplastic material mixer is mainly used for mixing thermoplastic materials (such as rubber and plastic) with additives; The mixing machines for powdery and granular solid materials are mostly intermittently operated, and also include machines with mixing and grinding functions, such as wheel rolling machines. During mixing, all materials involved in mixing shall be evenly distributed. The degree of mixing can be divided into three states: ideal mixing, random mixing and complete non-mixing. The mixing degree of various materials in the mixing machine depends on the proportion, physical state and characteristics of the materials to be mixed, as well as the type of mixing machine used and the duration of mixing operation.



The mixing of liquid mainly depends on the mechanical stirrer, air flow and the jet of the liquid to be mixed, so that the materials to be mixed are stirred to achieve uniform mixing. Stirring causes part of the liquid to flow, and the flowing liquid pushes the liquid around it, resulting in the formation of a circulating liquid flow in the solvent. The resulting diffusion between liquids is called the main body convection diffusion. When the liquid flow velocity caused by agitation is very high, there will be shear action at the interface between the high-speed liquid flow and the surrounding low-speed liquid flow, thus generating a large number of local vortices. These vortices spread rapidly around and bring more liquid into the vortex. The turbulent convection diffusion formed in a small range is called eddy diffusion.



The mixing mechanism of a small amount of insoluble powdery solid and liquid is different from the density component, and the mixing mechanism of immiscible liquid is the same, but stirring cannot change the particle size of powdery solid. If the settling velocity of solid particles cannot be less than the flow velocity of liquid before mixing, no matter what mixing method is used, it will not form a uniform suspension.



The mixing of different pastes is mainly to divide the materials to be mixed repeatedly and make them subject to the strong shearing effect caused by the actions of pressing, rolling, squeezing, etc., and then merge and knead repeatedly to reach the required mixing degree. This kind of mixing is difficult to achieve ideal mixing and can only achieve random mixing. The powdery solid is mixed with a small amount of liquid to form a paste, and its mixing mechanism is the same as that of paste material.
