Three differences between Disperser and Grinder

Dispersers and Grinders are commonly used industrial equipment for different processes and application fields. They have some differences in working principle, operation mode and application scenarios, as follows:

How it works:

Disperser: Disperser disperses and mixes materials through high-speed rotating cutting, shearing and impact forces. It uses a high-speed rotating dispersion disc or disperser to disperse granular or solid materials into a liquid medium through shear and liquid friction.

Grinding machine: The grinding machine finely grinds and grinds materials through the friction and collision of abrasive particles in the grinding medium. It uses the relative motion between the abrasive and the grinding medium to achieve crushing, refining and mixing.

Operation method:

Disperser: The disperser usually adopts rotary operation, and the disperser or disperser is driven by a motor to rotate at high speed to disperse the material into the liquid medium. The operator needs to control and adjust the speed, time and process parameters of the disperser.

Grinder: The Grinder usually uses reciprocating operation to grind and mix through the relative movement between the grinding disc or grinding ball and the material. The operator needs to control the running time of the Grinder, the amount of medium added and the choice of grinding medium.

Application scenario:

Disperser: Disperser is mainly used for particle dispersion, suspension preparation, colloid grinding and mixing. Common application fields include coatings, inks, cosmetics, food and medicine industries.

Grinders: Grinders are mainly used for fine grinding, grinding and mixing of materials. Common application fields include pigments, coatings, inks, ceramics, electronic materials and chemical industries.

In general, dispersers are mainly used to disperse granular or solid materials into liquid media to achieve suspension, homogenization and mixing, while Grinders are mainly used to finely grind, grind and mix materials to achieve the required particle size and quality requirements. They are different in working principles and application scenarios, so in specific processes, appropriate equipment needs to be selected according to needs.
