Silverson Disintegrator / Dissolvers for Polymers and Lube Oils

Silverson Machines are renowned for their Disintegrator 2500, specified by many of the world’s major oil companies. As a world leader in the design and manufacture of this type of high shear mixing equipment, you can trust Silverson to find a solution to your mixing needs.

The Disintegrator 2500 mixing system will disintegrate, solubilise or disperse the largest of solids - up to 1 metre across - in a single operation, often reducing processing times from days to hours.

The D2500 incorporates a powerful and unique Silverson mixer located in the bottom of a custom-built vessel. 

Here's how it works: The unit is charged with liquid and started. 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, into the workhead. The materials are literally ripped apart as the workhead will rapidly shear lumps and slices off the edges and corners before being dispersed throughout the mix.

Rapid fragmentation of the large solids continues until all the particles are small enough to be drawn into the workhead for further disintegration. Materials are discharged horizontally from the workhead and forced up the vessel’s walls, drawn into the vortex and repeatedly through the workhead, progressively reducing the solids until they are down to granular size.

At this stage, the self-pumping Silverson In-Line mixer is started. The product is drawn from the bottom of the vessel, processed through the In-Line mixer’s high shear rotor/stator workhead for refinement and passed back into the top of the vessel, ensuring complete solution or suspension.

The use of the D2500 comes with many advantages:

• The disintegrator can handle all types of polymer, including hard solids, cold-flow materials and compressed powder or granule bales. 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 vessel
• 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 excess waste

For smaller scale and in-tank operations, similar results can be achieved with the Silverson Duplex. The Duplex was specifically developed for the disintegration and solubilisation of solid rubbers and polymers for the luboil and adhesive industries.

The Duplex differs from the standard multipurpose batch mixers in having two workheads facing in opposite directions; the upper head pulls materials down from the surface of the mix, while the lower head draws material up from the base of the vessel.

The combined use of two workheads makes the Duplex ideal for applications where light or buoyant material (powders, rubbers and polymers, etc.) needs to be drawn down from the surface of a mix and rapidly dispersed.
