The new Rockster wind sifter RVB1700 in use by a customer in Portugal.

The Austrian company Rockster Recycler GmbH has developed an wind sifter retrofit kit for its mobile crushers. With relatively little effort, the final products to be produced can be significantly increased in value. The partially unavoidable contaminations in the crushed material are simply blown away, according to the manufacturer.

The wind sifter RVB1700 separates non-mineral components, like paper, wood or foils, from the crushed material. This results in a cleaner and higher quality final product. It is therefore possible for Rockster customers to work more environmentally friendly and more economically.

Non-Mineral Substances Are Separated From Mineral Substances

The centerpiece of the RVB1700 is a variably adjustable blower, which is connected by flexible hoses to the air nozzle. This air nozzle is adjustable in inclination. Through the narrow slot of the air nozzle, the air emerges and blows diagonally from below through the crushed material, so that the unwanted lightweight materials (e.g., polystyrene, textiles, gypsum, foils, wood, etc.) get removed.

The Rockster RVB1700 wind sifter is hydraulically operated and can be completely integrated into each Rockster crushing plant.

The “wind sifter package” is offered as an option by Rockster for new machines. For existing plants Rockster Recycler offers a retrofit kit. This can be installed by the Rockster service team at the headquarters in Ennsdorf or on site at the customer. If the customer has the technical installation options in-house, this retrofit package also can be mounted in-house.
