Operating Pressures
From full vacuum up to 150psi (10 Bar). Higher pressure units are available on request.
Silverson's new hygienic series of high shear bottom entry mixers are designed to fit into the bottom or side of a mixing vessel. These high shear mixers are typically used in conjunction with a slow speed anchor stirrer or scraper unit for high viscosity products.
The Silverson bottom entry mixer gives high shear homogenisation while the stirrer/scraper distributes the homogenised output uniformly through the vessel. This is ideal for high viscosity cosmetic, pharmaceutical and food products.
Bottom entry mixers can also be used by themselves on low viscosity products and to wet out powders. Silverson bottom entry mixers offer full compliance with GMP and USDA requirements.

Aeration Free Operating Pressures
General duty in-line models are designed for operation on pressures of up to 100 psi (7 bar). Higher pressure units are available on request.
HIGH VISCOSITY IN-LINE MIXER
Silverson’s new UHS-HV Series of In-Line Mixers is designed for processing higher viscosity products. These mixers feature a unique and innovative “pumping rotor” design which allows the mixer to achieve very high flow rates compared with standard In-Line models.
This pumping rate is maintained as viscosity rises, eliminating the need for an additional feed pump. UHS-HV In-Line mixers are hygienic in design, being based on the EHEDG and 3-A tpv Certified UHS range. Submission to the relevant bodies for testing and certification will be the next step in the development of this product line.
Applications
UHS-HV In-Line Mixers are suitable for mixing high viscosity slurries, gels and creams in the food, pharmaceutical, cosmetic and chemical industries.
Performance
UHS-HV In-Line mixers offer a substantially higher flow rate than the standard LS and UHS In-Line models. The flow curve below shows a 450 UHS-HV versus a 450 LS In-Line to illustrate this difference in pumping rate.

DISINTEGRATOR 2500
Silverson's mighty disintegrator 2500 mixing system will disintegrate, solubilise or disperse the largest of solids - up to 1 metre across - in a single operation, and in times you wouldn't believe.
The disintegrator 2500 incorporates a powerful and unique Silverson mixer located in the bottom of a custom-built vessel. The mixer exerts a massive suction downwards from the surface of the liquid, pulling down even the most buoyant of solids, no matter what the size. These solids are literally ripped apart and dispersed throughout the mix, and with the refinement of a Silverson In-line mixer included in the system, are totally solubilised or suspended.
For smaller solids, Silverson offers the duplex disintegrator/dissolver, which was specifically developed for the disintegration and solubilisation of solid rubbers and polymers for the lube oil and adhesive industries.
Capacity
1,000 to 100,000 litres
Components
Silverson disintegrator 2500 systems typically include:
-
Silverson bottom entry disintegrator/dissolver – provides rapid disintegration of solids and wetting of powders and is the prime mover of the fluid in the vessel
-
Silverson in-line high shear mixer – maximises the solution of the fine particles created by the bottom entry unit and allows for instant homogenisation of additive fluids.
-
Special disintegrator 2500 vessel, associated piping, valves, fittings and controls – optimises mixing characteristics to suit application needs.
Typical Applications
-
Rapid solution of rubber and polymer blocks into lubricating oils, solvents and bitumen for the production of VM luboils, adhesives and polymer modified bitumen for road surfacing.
-
Recovery of waste candy.
-
Wet crumbing of waste rubber.
-
Rapid dispersion of large volumes of pow11der or materials which are difficult to wet out and have a tendency to "raft."
-
Dispersion of filter cakes.
