Greaves VHSD10 High Speed disperser

• Dispersing powders into liquids to create homogeneous suspensions in paint, ink, and coating production.
• Mixing and dissolving ingredients for pharmaceutical and cosmetic creams, lotions, and gels.
• Emulsifying food products such as sauces, dressings, and dairy alternatives.
• Breaking down agglomerates and achieving fine dispersions in chemical processing.

Typical capacity

High-speed dispersers of this class are commonly used with batch volumes ranging from 200 to 1,000 litres, often directly into tote bins or process vessels.

Power supply

Units like the Greaves VHSD10 typically require a 3-phase industrial power supply, commonly 400V, 50Hz in the UK, with motor ratings for this type of equipment often between 5.5 kW and 18.5 kW.

Speed range

High shear dispersers are characterised by variable speed capabilities, typically offering a range from approximately 200 rpm for gentle mixing up to 1,500-3,000 rpm for high shear applications.

Construction material

For hygiene and corrosion resistance, units in this category are typically constructed from stainless steel, with contact parts often in 304 or 316 grade stainless steel.

Lift mechanism

Electro-hydraulic lift mechanisms are standard for this type of disperser, allowing for precise positioning of the impeller within various vessel sizes and easy cleaning.

Control features

Common control features include variable speed adjustment, timer functions, and emergency stop, often with integrated motor protection.

• What is the primary function of a high-speed disperser?

  A high-speed disperser is designed to rapidly incorporate powders into liquids, break down agglomerates, and create fine, homogeneous dispersions or suspensions through high shear forces generated by a rotating impeller.

• Can this equipment handle viscous materials?

• What maintenance is typically required for a unit like this?

• Is this suitable for ATEX environments?

• What type of impeller does a high-speed disperser typically use?

Homogenizers are regarded as reliable workhorses in food processing operations. Buyers typically value units with consistent output and straightforward maintenance requirements. When purchasing used equipment, inspectors should assess pump condition, seal integrity, and whether service records are available. Industry users commonly appreciate homogenizers for their durability and ability to handle demanding production schedules. Key considerations include verifying pressure ratings match production needs and confirming spare parts availability for the specific model.
