1. 1. Overview A hydraulic disperser machines is an industrial mixing device used primarily for the dispersion and homogenization of materials in various industries such as paint, coatings, inks, adhesives, cosmetics, chemicals, and pharmaceuticals. It is engineered to efficiently mix high-viscosity or solid-liquid mixtures by employing high-speed rotational blades and a hydraulic lifting mechanism. 2. Working Principle The hydraulic disperser operates on the principle of mechanical shear force. A dispersing blade, usually a saw-tooth type disc, rotates at high speed, creating a strong vortex within the mixing vessel. This action draws materials from the top of the batch to the blade and then forces them outward and upward, resulting in rapid breakdown of agglomerates and uniform distribution of particles throughout the medium. The hydraulic system is responsible for the vertical movement of the disperser head, allowing for convenient adjustment of the blade position within the mixing vessel. This improves mixing efficiency and allows the machine to handle different batch sizes. Electric Motor Powers the dispersing blade Varies in horsepower (HP) depending on batch size and material viscosity Mixing Vessel or Tank Can be fixed or movable Often jacketed for temperature control (heating/cooling) Control Panel Provides control over speed, height, and safety functions May include digital displays, timers, and programmable settings 3.

A High Speed Disperser (HSD) is an industrial machine commonly used in various industries such as paint, coatings, inks, adhesives, chemicals, and pharmaceuticals for mixing, dispersing, and homogenizing materials. It is especially effective in breaking down particle agglomerates and evenly distributing solids into liquids.

• High-Speed Rotating Shaft: Typically operates at speeds between 1,200 – 3,600 RPM.

• Disc Blade (Cowles Blade): Generates high shear forces that promote particle size reduction.

• Hydraulic or Pneumatic Lifting: To adjust the height of the disperser head for better mixing.

• Variable Speed Control: Optional, for precise process control.

• Capacity Range: From small lab units (1–5 liters) to large production models (1000+ liters).

• Paints and Coatings

• Printing Inks

• Pigments and Dyes

• Cosmetics

• Pharmaceuticals

• Food Processing (e.g., sauces, emulsions)

1. The disperser blade rotates at high speed.

2. It creates a vortex that draws materials from the top to the blade.

3. High shear occurs at the tip of the blade, breaking down particles and mixing them into the base fluid.

4. The result is a uniform dispersion with reduced particle size.

• Fast and efficient mixing and dispersion.

• Improved product quality due to uniform particle size.

• Reduces production time.

• Easy to clean and maintain (especially with stainless steel construction.

•  Paint manufacturing, a High Speed Disperser (HSD) is one of the most critical machines in the premixing and grinding stage. Here's a detailed breakdown of what you need to consider when choosing or designing an HSD specifically for paint production:

•  High Speed Disperser for Paint Manufacturing
• ✅ Main Functions

  • Wetting pigments and fillers in resin/solvent.

  • Breaking agglomerates and reducing particle size.

  • Achieving a uniform, stable dispersion before final letdown.
