silicone rubber. Mixing of tough masses such as rubber require special equipment such as kneaders. These mixers need to be robust in construction and consume high power.

It consists of a horizontal cylindrical container with multiple plough shaped shovels mounted on the main shaft. With 30% 70 % filling of the container, the size, number and positioning, geometric shape and peripheral speed of the mixing elements are co-ordinated in such a way that they produce a whirling, three-dimensional product movement. The resultant turbulence in the mix, whereby the entire product is constantly involved in the mixing process, prevents the formation of dead-spots or low-movement zones in the mixing container and ensures fast and homogenous mixing. The mixing elements are specially designed to lift the material from the inside wall of the container without squashing the particles against the wall. In addition, separately driven high-speed choppers can be installed to disperse agglomerations and control granulation during the mixing process in co-ordination with the mixing elements.

Chopper Action (Optional)

Single or multiple choppers are located in the lower part of the mixing container in such a way that the chopper assembly is inserted into the wall of the container at points in between the flights of two adjacent mixing shovels. The shovels operate beneath the rotating choppers. Together with the mixing shovels, the high-speed choppers remove lumps in the raw material, chop pasty additives and prevent formation of agglomerates on liquid addition. The choppers can be switched on and off, independent of the main drive shaft. Thus, the influence of the chopper action on the product mix can be controlled.

Unique is happy to announce the successful development of the new design ofDouble Planetary Mixeralong withHydraulic Discharge System for high viscosity materials.

TheDouble Planetary Mixeris capable of mixing non flowing materials up to several million centipoises with the simple push button operation. The mixed material from the Double Planetary Mixer (with change can design) can be transferred along the container to the discharge system for fast discharge. The hydraulic system can discharge large batch sizes in minutes into containers, post processing equipment, thereby eliminating the otherwise wasted time requirement for scraping heavy or sticky materials from the mixing container. The container can then be cleaned and made ready for the next batch mixing. Multiple cans can be provided to improve productivity and for faster turnaround with different types of process materials.

The Double Planetary Mixer along with discharge system can be used for adhesive, sealants, pharmaceuticals, dental compounds, cosmetics, plastics and many other high viscosity materials.

Industrial applications involve mixing of solids to solids (free flowing solids and pasty materials), solids to liquids, solids to gas (reactions), liquids to liquids, and liquids to gas. Fluid mixing is generally associated with liquid liquid mixing and liquid-gas mixing. Though mixing of solids to some extent resembles the mixing of low-viscosity liquids, Fluid mixing depends on the creation of flow currents, which transport unmixed material to the mixing zone adjacent to the impeller. In heavy pastes or masses of particulate solids there are no such currents are possible and mixing is accomplished by other means, Power required for mixing of dry solids and viscous pastes is higher than that consumed in blending of liquids.

Media : Solid Powders, Dough, Viscous Pastes

Mode of Operation : Batch Mixing

Design and Operation

Mixing Vessel - The double planetary mixer consists of a vertical cylindrical vessel (referred to as the bowl) within which two mixing blades (referred to as beaters) rotate. The double planetary mixer belongs to the family of change can mixers. In change can mixers; there is a provision to remove the mixing bowl from the mixer assembly either by lowering the bowl from the mixer operating position, or by lifting the mixer drive system. The lifting and lowering is through hydraulic operation. A cylindrical cover is provided between the planetary head and the mixer bowl. Charging nozzles, liquid spray pipes, vacuum connections may be provided on the charging cover.

Mixing Blades - The beaters rotate on their own axes, and at the same time they orbit the mixing vessel around the axis of the bowl. The clearance between the external periphery of the beaters and the internal walls of the bowl is generally in the range of 2 – 3 mm.

Mixer Drive System – The double planetary mixer is powered by a drive system comprising of a motor and gearbox that drive the planetary head assembly of the mixer. The planetary head assembly consists of a gear train that causes the planetary motion of the beaters.

Mixer Seals – The mixer shaft is provided with a sealing arrangement in the area where it exits the planetary head. The mixer seals in a double planetary mixer do not come in contact with the process material.

Material Charging and Discharging – Material is loaded in the bowl directly, or may be charged through nozzles provided on the top cover. Discharge of material is generally through manual scooping of material from the top of the bowl. 

Heat Transfer – Double planetary mixers are commonly provided with jackets for circulation of heating or cooling media.
