High Speed High Shear Mixers Bottom Entry Mixers & Disintegrators

The Silverson Principle For over 75 years Silverson has specialised in the manufacture of quality high shear mixers for processing and manufacturing industries worldwide. With customers in over 150 countries, and serving industries as diverse as food, pharmaceuticals, cosmetics, luboils and petrochemicals, Silverson has become the world leader in the field of high shear mixing. Time after time, companies specify Silverson mixers as the “standard” equipment for their manufacturing process. The key to this success is based on the professionalism and commitment Silverson shows to each of its...

Why Silverson? Speed The exceptionally rapid Silverson mixing action substantially reduces process times compared with conventional agitators and mixers and can reduce mixing times by up to 90%. Versatility The advantage of the Silverson approach to mixing is that any one machine can perform the duties that in the past may have required several different pieces of process equipment. This unrivalled versatility allows any machine to perform the widest range of mixing applications: -  Blending - A homogeneous product is rapidly produced when blending liquids of similar or greatly varying...

Bottom Entry Mixers Bottom Entry Mixers Silverson’s hygienic High Shear Bottom Entry mixers are ideal for disintegrating solids and incorporating powders that have a tendency to float on the liquid surface. They can also be 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. As with all Silverson rotor/stator mixers,...

Bottom Entry Mixer Works Stage 1 The high speed rotation of the rotor blades exerts a powerful suction, drawing liquid and solid materials downwards into the centre of the workhead. Centrifugal force then drives the materials towards the periphery of the workhead where they are subjected to intense hydraulic shear in the clearance between the rotor and the stator. The product is forced out through the stator and projected radially at high speed towards the sides of the mixing vessel. Fresh material is simultaneously drawn into the workhead, maintaining the mixing cycle.

Pilot Disintegrator Plant The Silverson Pilot Disintegrator Plant was designed to provide a small scale version of the D2500 Disintegrator/Dissolver for R&D installations, but its versatility has seen it being used as a production unit for batches of around 150 litres in applications as diverse as luboils, chemicals and foods. The unit comprises a vessel mounted Bottom Entry mixer coupled to a High Shear InLine mixer homogeniser, and incorporates a control panel and all associated pipework. During operation, the Bottom Entry mixer initially reduces solids down to granular size. The In-Line...

Disintegrator 2500 The D2500 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.

D2500 Works The D2500 is a self-contained high-powered unit consisting of a specially designed Silverson high shear rotor/stator disintegrating workhead set into a custom-built vessel coupled with a Silverson high shear In-Line mixer. The unit is charged with liquid and started. Large solids are fed into the vessel and drawn down into the workhead which will rapidly shear lumps and slices off the edges and corners. These will be drawn into the interior of the workhead, driven by centrifugal force to the periphery and further sheared by the rotor tips against the edges of the stator as they...

D2500 Advantages -  Size and shape of product is inconsequential. The Disintegrator 2500 can take odd shapes and the largest sized polymer bales commercially produced. -  No need for pre-grinding, slicing or cutting of large solids. All solids are dissolved in one vesse -  Elimination of additional equipment such as grinders or choppers reduces maintenance costs and dust emissions -  Puts products into complete solution or suspension without leaving undesired particles on vessel walls -  Can handle poly-wrapped bales without prior removal of wrapper, eliminating the need for cutting and...
