EXPANDING THE MAX. The BUBLON-Technology. The innovation in the expansion of fine-grained industrial minerals.

THE PROBLEM There is an increasing demand for high-quality mineral insulants and light-weight fillers. In conventional plants, perlite granules are expanded in an uncontrolled manner through abrupt heating which creates cracks and makes them burst. The lower quality of these granules is of limited use for the construction and insulants industries. THE SOLUTION The innovative BUBLON-Technology allows, for the first time, a controlled expansion of industrial minerals based on an entirely natural and nearly inexhaustible raw material. The light-weight granules are characterized by a glazed and closed...

THE BUBLON LIGHT-WEIGHT FILLER. UNIQUELY VERSATILE. © shutterstock.com / Subbotina Anna The BUBLON-Technology can expand light-weight granules with different grain sizes which have a wide range of applications, such as in the construction industry, in fire protection, cryogenics, in the shipbuilding and automotive industries as well as in the aviation and plastic industries. With so many possible uses, there is almost no limit to this light-weight granulate.

MODULAR DESIGN. THE BUBLON-TECHNOLOGY. The starting point in the BUBLON-Technology is the raw sand silo. This is where the mechanically processed (crushed and screened) raw material is stored. The material is then fed through the down-stream rotary feeder. The elevator feeds the fluidised bed dryer. The fluid bed is operated in a closed cycle and is fuelled either electrically or with natural gas. After the thermal preparation, the raw sand is moved from the fluid bed into a container from where the raw sand is continuously conveyed further into the electrically heated expansion furnace. The...

THE SOLUTION. THE CONTROLLED EXPANSION. With the innovative BUBLON-Technology, the temperature in the expansion furnace can be individually adjusted in different zones. The expansion furnace is heated electrically only in vertically arranged heating zones and modules, allowing a very finely adjustable temperature control. The expansion rate of the final light-weight material can be optimized through the number of modules used and optional air-stream sorting. This controlled expansion ensures light-weight materials with excellent product properties such as the glazed and closed surface. The expansion...

The volumetric mass of the expanded perlite in its normal and ground-up state is compared using a helium pycnometer. The resulting quotient is a measure for the glazed and closed surface.

FOR THE HIGHEST DEMANDS OF THE CONSTRUCTION INDUSTRY. Symbolic image With BUBLON-Technology, fine-grained industrial minerals are expanded to high-quality light-weight fillers with a glazed and closed surface. Thanks to the glazed and closed surface and the resulting low dust generation and low water absorption these granules are ideally suited for the production of light plasters, insulating boards and acoustic panels as well as complex designs for exterior insulation and finishing systems. The light-weight fillers are diffusion-open, pollutant-free, resistant against vermin infestation and...

BE SAFE. IDEAL PROPERTIES FOR FIRE PROTECTION. An important advantage of the light-weight granules expanded with BUBLON-Technology is their excellent fire protection properties. Because they are incombustible, they meet the requirements of the highest fire-resistance rating and can be used in the production of fire doors, decorative fire protection, chimney bricks and coating stucco. Test sample fire protection slabs and oven details.

Much more than a corporate slogan: „Expanding the Max“ not only means the expansion of industrial minerals to produce light-weight granules but also • maximum know-how and maximum expertise for our customers • maximum added value and sustainability through development of industrial solutions • and last but not least maximum success for our customers. Bublon GmbH is an independent subsidiary of world market leader Binder+Co and handles the global commercialization of the BUBLON-Technology, which was first presented to a wide expert public in the autumn of 2011. The core process, which is the controlled...
