The three stage mixer/homogenisers manufactured by Advanced Engineering (Middleton) Ltd are high performance machines designed to provide the finer emulsions, dispersions and creams required for many processing applications (Plate 1).

These are in-line processors, designed for higher volume applications, and claiming many advantages over conventional immersion mixers for batch work. The need for mixing vessels is said to be eliminated, saving considerable space and the units are both easy to clean and maintain. They are precision engineered and designed to provide long trouble-free operation.

They can be used for single pass or recirculatory processing for a diverse range of functions including aerating, decomposing, dissolving, emulsifying, extracting, homogenising, mixing, precipitating, shredding, suspending etc. They are suited to a wide range of applications from aerosols to ceramics, dyes to lacquers. Even highly viscous media can be accommodated by utilising a supplementary feed pump.

The key to performance is said to be the interchangeable precision rotor/stator cutters in the dispersion head. Four options are available to provide coarse, medium, fine and superfine finishes. The processing medium passes through three sets of fast rotating cutter blades and the exceptionally high tip speeds achieved provide a powerful and highly efficient multi-shear action to cover the most demanding applications. Special purpose cutter heads can also be manufactured where required for difficult or specialised media.

Three stage mixers can be supplied for either direct or gearbox drive. Motors from 5.5 to 30hp can be fitted, giving typical maximum throughput volumes of 2,500 to 20,000 litres/hr. All contact parts are in 316 stainless steel and flameproofed designs can be supplied for operation in Zone I areas, gas groups I 1a and I 1b. Special purpose machines and a number of design options can also be supplied.
