High-speed Disperser

High-Speed Disperser

1. Product Overview

1.1 General Description

The high-speed disperser is key equipment for dispersing, mixing, dissolving and milling liquid materials in the coatings, inks and chemical industries. Its high-speed saw-tooth dispersing disc applies intense shear and centrifugal force, rapidly dispersing agglomerated powder particles into the liquid phase, while the air entrained into the material provides an additional stirring and mixing effect. With disc tip speeds of up to 20-25m/s, it delivers strong shear and high dispersion efficiency. Modern high-speed dispersers feature hydraulic lifting, variable-frequency speed control and explosion-proof design for convenient, safe operation. They are widely used in the coatings, inks, pigments, adhesives, food and pharmaceutical industries.

2. Working Principle

2.1 High-Speed Disperser Process Flow

Complete process flow: charging → low-speed pre-mixing → medium-speed wetting and dispersion → high-shear dispersion → fineness check → adjustment → discharge. As the disc rotates at high speed, the saw teeth on its rim accelerate and fling the material outward, generating intense shear, while axial circulation above and below the disc continuously passes the material through the high-shear zone. Under shear and impact, powder particles are wetted, deagglomerated and dispersed into the liquid phase. The shape and number of the saw teeth (typically 4-8) affect dispersion performance. The lifting system allows the disc depth to be adjusted during operation, starting low and rising gradually.
