The ARS centrifugal screener is a high-efficiency separation system designed for continuous screening and quality control of dry powder products or bulk materials.
By exploiting centrifugal force, it ensures precise particle separation, high throughput, and dust-free operation, all within a compact, enclosed, and hygienic design.

Designed for easy integration into both new and existing process lines, the ARS centrifugal screener is widely used in the food, chemical, pharmaceutical, and recycling industries, where fine, consistent, and clean screening is required with the highest level of reliability.

Operating Principle

The material to be processed is fed into the screener body via a screw conveyor or dosing system and conveyed into the screening chamber, where a high-speed rotating paddle pushes the product against the inner surface of the cylindrical screen.

The centrifugal force projects the material onto the screening surface:

• fine particles pass through the mesh and are conveyed to the main outlet as acceptable product;
• coarse particles or agglomerates are diverted to a secondary discharge, ensuring precise and continuous separation.

Main Technical Features

• Fully enclosed, dust-tight structure, ideal for processes requiring high hygienic standards.
• Manufactured from high-quality materials (AISI 304, AISI 316 stainless steel or carbon steel), with optional mirror-polished finish for food and pharmaceutical applications.
• Quick disassembly and easy access for cleaning and product changeover, without the need for tools.
• Interchangeable screening meshes, available in various mesh sizes depending on the required particle size.
• Asynchronous motor with direct drive, ensuring stable, quiet operation and low maintenance.
• Customizable configurations for inlet and outlet positions, suitable for continuous or batch processes.
• ATEX versions available for use in potentially explosive atmospheres.

Operational Advantages

• High separation efficiency and consistent particle size distribution.
• Hygienic, enclosed, and dust-free process.
• Low maintenance requirements and reduced energy consumption.
• High production capacity with a compact design.
• Effective protection of downstream process equipment.

Applications

Ideal for safety screening, classification, and refinement of fine or difficult-to-handle products, such as:

• flours, starches, milk powder, sugars;
• chemical powders, fertilizers, pigments, and colorants;
• additives, resins, carbonates, and recycled materials.
