Westeria windsifters are robust, powerful and elaborately designed.

The patented Westeria windsifter technology boasts a powerful process for separating light and heavy material.

Materials are separated in the windsifter using a process made up of three basic components - the acceleration belt, the air nozzle and the windsifter separation drum.

The windsifter achieves good sifting through the even, single-layer distribution of the input material, which is homogenously spread out across the entire width of the windsifter belt and passed to the feed belt.

The material in the windsifter is accelerated here to a suitable speed and transported to the discharge edge. The material falling from above meets an upward flow generated by an adjustable air nozzle attached below the feed belt in the windsifter.

The air stream meets the upper area of the rotation drum in the windsifter and is fed via this into the expansion chamber with the laminar flow.

The material in the windsifter meets the air stream and is separated into light and heavy material.

The light materials are transported via an air stream at higher speed into the expansion chamber where the air speed is radically reduced so that the light materials end up in a container or on a discharge belt. The heavy materials fall downward before the rotation drum in the windsifter into a container or onto a discharge belt.

The volume of air introduced in the expansion chamber is extracted again in the upper area of the windsifter and either suctioned back in by the blower or fed into a filtering system, depending on the individual case. Westeria has designed a special windsifter with which the input material can be precisely sorted into three groups with a high degree of separation efficiency in order to obtain high-quality recycling materials. .

Functional principle: Westeria windsifters

Benefits of the Westeria windsifter

• Westeria windsifters are based on tried-and-tested technology with over 300 assembled units
• Throughput of up to 250 t/h or 200 m³/h depending on the material
• Westeria windsifters have a working width from 800 to 2000 mm
• Patented Westeria windsifter solution
• Continuous enhancement of the windsifter through trials, flow simulations and customer feedback
• Highly efficient thanks to optimised flow design
• Individual adjustment
• 3 different demonstration models for customer presentations
• Test system for the trial sifting of material supplied by customers
• Westeria windsifters separate excellently thanks to the high degree of separation efficiency
• Compact design, little space needed, especially suited for retrofitting
• Adapted peripheral equipment
• Can be used in the air circulation process, therefore very little exhaust air
• Semi-portable, wheel-portable, caterpillar-portable, stationary
• Windsifters can be set precisely for any material by adjusting the feed speed, air speed, angle of the air nozzle and the position of the feed belt
• High level of safety for shredders, the windsifter more reliably separates even critical impurities (iron and non-iron materials) and avoids high costs for spare parts for shredders and granulators, long downtimes following shredder and granulator damage are avoided
• Optional automated adjustment for quick adaptation to different materials
• Triple sifter: degree of separation efficiency between average and light groups can be precisely set for very clean heavy and light groups
• Safety level before shredders

Range of applications for the windsifter

• Windsifters can be used for construction rubble

Construction rubble systems

• Stationary and mobile windsifters
• Sorting into heavy and light groups
• Many years of experience
• Robust design
• Long service life
• Customised complete systems

We have many years of experience as a professional manufacturer of windsifters for processing construction rubble. In the construction rubble sorting segment in particular, robust systems with a long service life and high throughput are in demand.

Our engineers also design complete systems from hopper systems to conveyors and mobile or stationary windsifters with the associated peripheral equipment.

Westeria offers you practical machines and systems that reliably separate the fed material into intended groups. Of course, our trained staff is still available after assembly and commissioning for any questions you may have. .
