Batch mixers
Silverson offers a complete range of multi-purpose batch mixers. The machines are able to perform the widest variety of applications - mixing, emulsifying, homogenising, disintegrating, dissolving - with an efficiency and flexibility unmatched by other machines. Capacities from 5 to 30,000 litres. The Silverson range of High Shear Batch mixers are of robust and simple construction, which ensures that cleaning and maintenance is kept to an absolute minimum. The range can be divided into two distinct categories ¨C Medium range and Large range models.
Large range ¨C Models 700X to MX
Silverson is the world leader in the specialised design and manufacture of large scale rotor/ stator mixers with a capacity of up to 30,000 litres. Al these machines are individual y built to order and constructed specifical y to suit each customer¡¯s requirements. The large scale mixers possess al the qualities and flexibility of Silverson¡¯s medium range models and include a number of additional and unique features.
Each mixer is designed and built to the highest possible engineering standards. From the special y balanced motors to the fitting of precision ground shafts which are finish turned in-house to ensure critical vibration free running, no aspect of manufacture escapes our rigorous inspection. These machines are designed to be maintained and serviced in-situ wherever possible. Quick release shaft couplings, split two-part downthrust propel er and hard-surfaced sacrificial shaft journal sleeves are just a few of the features designed to keep maintenance and downtime to a minimum. In every case Silverson¡¯s technical staff wil ensure that the customer¡¯s needs are precisely catered for.
Technical specifications
Materials of construction Al wetted parts in 316L stainless steel. Special materials on request. Bush material The bush wil normal y be bronze al oy or reinforced PTFE depending on the application. Motors TEFV (Total y Enclosed Fan Ventilated) and ATEX approved Flameproof motors are available as standard. Inverter rated, stainless steel and other motors are available as optional extras. Mounting Models BX up to GX can be mounted on mobile hydraulic floor stands. Alternatively they can be supplied with either a rectangular or circular flange for mounting on the vessel. Tri-clamp mounting is also available. Larger machines (Model 700X and above) require vessel mounting.
Sealing Al Silverson Batch mixers are designed for operation in open vessels. Single and double mechanical shaft sealing for operation under vacuum and/or positive pressure is available for most machines Cleaning The machines are in most cases self-cleaning, a short run between successive operations in water, detergent or an appropriate solvent being al that is necessary. For more thorough cleaning, dismantling is easy and downtime minimal.

Duplex disintegrator dissolver
The Duplex was specifical y developed for the disintegration and solubilisation of solid rubbers and polymers for the luboil and adhesive industries, but its success has now seen its introduction into al fields of mixing, whether chemical, pharmaceutical or food. The Duplex differs from the standard multipurpose batch mixers in having two workheads facing in opposite directions; the upper head pul s 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. Because of the added movement afforded by the two workheads the Duplex is also ideal for use on high viscosity materials.
Typical applications - Rapid solution of rubbers and polymers into lubricating oils, solvents and bitumen for the production of luboils, adhesives and bituminous compounds - Disintegration and dissolving of solid resin for the production of varnish - Vegetable and meat pur¨¦e/slurries - Recovery of waste confectionery
Specialised mixers
Abramix RBX No immersed bearing With the standard Silverson mixer a highly abrasive product can cause excessive wear on the bush and the shaft. In the Abramix RBX the bush has been completely eliminated by the use of a heavy-duty shaft which is firmly supported by two precision rol er bearings, situated above the level of the product being mixed. Minimum maintenance is a key feature of the design. Dry running Dry running in non-flammable products is possible, al owing mixing to continue uninterrupted while emptying the mixing vessel. Typical applications - Liquid Glazes: Preparation and Redispersion including Incorporation of Pigments, Wetting Agents, Hardeners, etc. - Ceramic slips - Clays and Silicas - Texture Paints - Foundry Compounds
Tubular mixers Silverson tubular mixers are designed for operation in sealed vessels where a product- lubricated mechanical shaft seal is required. Tubular mixers are suitable for operation under atmospheric or positive pressures and are ideal for mixing products where sealant fluids need to be avoided. The mixer shaft is sealed at its lower end by a conventional mechanical shaft seal which is lubricated and cooled by the product being mixed. As with al Silverson rotor/stator mixers, interchangeable stators are available to adapt the machine for varying processes. The tubular design also al ows the machine to fit through relatively smal diameter vessel openings. Each mixer is designed to suit individual process requirements. Typical applications - Active ingredients into inhalants - Injectables - Vaccines
