Air Cone Separators
The Air Cone Separator from JOEST reliably separates light fine material from heavy coarse material – even in complex material mixtures. It is based on a proven cross-flow separation method with an additional counter-flow separation zone for targeted post-separation of the light fraction.
The system is highly versatile and can be used, for example, for alternative fuels, plastic granules, wood pellets, or recycling materials such as shredded used tires. Depending on the requirements, JOEST offers various designs – for particularly dust-intensive processes, high volume flows, or poorly free-flowing materials.
Thanks to its compact design, high throughput capacity, and precise separation accuracy – even with fibrous or flat materials – the Air Cone Separator is a cost-effective solution for numerous industrial applications.
Function
The incoming product mixture is evenly distributed across the entire separation cross-section of the separator using a specially developed distribution system. In the separation zone, a multi-stage cross-flow and counter-flow process reliably separates the light product from the heavy product. While the heavy material passes through the upward air stream and is discharged at the base of the separator, the light material is carried upwards with the air and conveyed via a pipe to a separator unit.
The separator is designed so that the two material flows – rising light product and falling heavy product – do not interfere with each other. This ensures efficient separation, even with high material density. The required process air is generated by a radial fan.
Technical Features:
- Multi-stage separation with up to five separation zones for high separation efficiency
- Even product distribution through a well-designed feeding and distribution system
- Access flaps for easy cleaning and maintenance
- Viewing windows for visual process monitoring
Product Details
Several model series are available that can be precisely tailored to the specific application:

Fields of Application
Whether for tire recycling, dedusting, standard or recirculating air applications – our Air Cone Separators are ideal for separating light and heavy components in dry, free-flowing material mixtures – especially where mechanical screening reaches its limits due to material behavior. The Air Cone Separator proves particularly effective with inhomogeneous, fibrous, or flat particles – offering precise, energy-efficient, and virtually maintenance-free operation.
Shredder light fractions, alternative fuels, household waste mixtures
Rubber-textile mixtures, granulate fractions
Plastic flakes, films, density mixtures
RDF, SRF, wood fibers, contaminant mixtures
Equipment Options
For optimal adaptation to product, process, and environment, the Air Cone Separator offers a wide range of equipment options – modular, efficient, and individually configurable.
Adjustable separation zones and airflow control
Separation behavior and efficiency can be precisely tuned to the material flow via adjustable air volumes and separation zones.
Available with or without counter-flow separation
For particularly precise separation, a counter-flow zone can be integrated – ideal for post-separation of fine light particles from the main stream.
Flexible housing sizes for any throughput range
Various design sizes are available depending on material flow and plant size – ideal for small lines or high-volume recycling processes.
Energy-efficient recirculating air solution available
The recirculating air version saves energy by returning process air – ideal for continuous operation with low air consumption.
Combinable with cyclone separators or filters
For targeted dedusting or return air treatment, external filter or cyclone systems can be connected – modularly integrable.
Customizable discharges and outlet solutions
Light and heavy material discharges can be configured to suit the process – combinable with flaps, chutes, or conveying equipment.
Sound insulation or fully enclosed design
For noise-sensitive environments, the separator is available with sound-insulated housing or in a fully enclosed version.
Frequency converter for airflow control
The separation airflow can be precisely adjusted via frequency-controlled fans to match changing product characteristics.
Stainless steel or ATEX-compliant versions available
For sensitive or potentially explosive areas, versions in stainless steel or with certified ATEX components are available.
Compatible with JOEST dosing and conveying systems
The Conical Separator can be seamlessly integrated into complete systems – e.g. with dosing units, screens, or magnetic separation systems.
Advantages
The Air Cone Separator impresses with precise air classification, energy-efficient operation, and low-maintenance technology. Thanks to its modular design and individually adjustable separation zones, the system can be precisely adapted to different products and process conditions – ensuring consistently high separation accuracy in a compact footprint.
Precise separation by density and particle characteristics
The system reliably separates light and heavy material – even fine, fibrous, or flat particles with different aerodynamic properties.
Energy-efficient thanks to optional recirculating air system
The recirculating air solution significantly reduces the need for fresh air – ideal for continuous processes with low energy consumption and high cost-effectiveness.
Clog-free operation even with contaminants
Thanks to the purely air-based separation principle without mechanical parts in the separation zone, operation remains stable even with critical materials.
High separation efficiency through counter-flow separation
An additional separation zone can be optionally integrated to reliably remove remaining light material from the material flow.
Compact design with high performance
The vertical setup allows for space-saving integration into existing systems – with low maintenance requirements and high machine availability.
Flexible adjustment of separation parameters
Air volume, flow direction, and geometry can be precisely adjusted – ensuring consistent results even with changing materials.
Various configurations for every application
From standard units to dedusting versions and special designs for tire recycling or large volume flows – all from a single source.
Robust, low-maintenance, and durable design
The design operates without moving parts in the separation zone – minimizing wear, maintenance effort, and unplanned downtime.
