Silverson - Top Feed High Sheer Mixer

• Homogenising emulsions and suspensions in the pharmaceutical and cosmetic industries.
• Dispersing powders into liquids for food and beverage production, such as sauces and dairy products.
• Blending ingredients in chemical processing for paints, coatings, and adhesives.
• Creating fine dispersions in the production of lubricants and other specialty chemicals.

Typical capacity

For this class of equipment, capacities commonly range from laboratory scale (litres) up to several thousand litres for production units.

Power supply

Units typically require a 3-phase electrical supply, commonly 400V, 50Hz in the UK, with motor power varying significantly based on capacity and application.

Shear mechanism

Silverson high shear mixers utilise a precision-engineered rotor/stator workhead to achieve intense mixing action.

Construction materials

Process contact parts are typically manufactured from 316L stainless steel, suitable for hygienic and corrosive applications.

Mounting

Top-feed units are designed to be mounted directly over the processing vessel, often with a lifting mechanism for easy access and cleaning.

Motor type

Commonly fitted with TEFC (Totally Enclosed Fan Cooled) motors, often IP55 rated, with options for ATEX compliance in hazardous areas.

• What is a 'top feed' high shear mixer?

  A top feed mixer is designed to be mounted above the processing vessel, with the mixing head submerged into the product from the top. This configuration is common for batch processing.

• What is the primary benefit of a high shear mixer?

• Can this mixer handle viscous products?

• Is this unit suitable for continuous operation?

• What maintenance is typically required for a high shear mixer?

Lab mixers and stirrers hold strong reputations for reliability and durability. Buyers typically prioritise motor condition, speed range suitability, and vessel compatibility when purchasing used units. The equipment category is valued for consistent performance across research and production settings. Key strengths include robust construction, straightforward maintenance, and long operational lifespans. Corrosion resistance of wetted parts merits careful inspection. These devices remain dependable workhorses in pharmaceutical, biotech, and laboratory environments, offering solid value when sourced from reputable sellers with clear service histories.
