      Tumbler Screening Machine From Botek machinery- 3D Elliptical Separator for or Powder or granule. Engineered for delicate powders and granular materials (>100 microns), our 3D elliptical motion separator achieves up to 95%! (MISSING)fficiency with separation precision down to 20 microns. Ideal for demanding applications in pharmaceutical, food processing, chemical, and metal powder industries, this system sets new standards in gentle yet high-capacity screening.
      How Our 3D Motion Technology Works
      Unlike conventional vibratory screens, our proprietary three-dimensional elliptical movement creates a unique tumbling action. Material fed to the center of the top screen distributes evenly across the surface, executing a controlled circular motion. This optimized trajectory allows fine particles to pass through mesh openings efficiently while coarser materials discharge from peripheral outlets. The adjustable RPM and equipment angling maximize material flow control and screening time.

      Advantages

      Extended Mesh Lifetime: Up to 10x longer screen life compared to standard vibratory sieves
      Gentle Product Handling: Significantly reduced particle breakage for fragile materials
      Enhanced Throughput: Up to 6x greater capacity per square meter
      Multi-Stage Grading: Capable of separating materials into up to 6 distinct fractions with 5 screening decks
      Quiet Operation: Noise levels maintained below 75 dB
      Low Maintenance: Quick-release mechanisms and optional ball/ultrasonic cleaning systems minimize downtime.

      Technical Specifications

      Tumbler screening machine FAQS

      A tumbler screening machine, also known as a 3D elliptical separator or gyratory sifter, operates on a unique three-dimensional elliptical motion. Unlike traditional vibrating screens that rely on high-intensity vertical or linear vibrations, it produces a gentle, tumbling, and spreading action. This results in higher efficiency for fine powders, longer screen life, and significantly less product degradation, making it ideal for fragile, sticky, or light materials.

      Our tumbler screeners excel with a wide range of dry, granular, and powder materials. Common applications include:
      Food & Beverage:​ Sugar, flour, starch, cocoa, protein powder, spices.
      Pharmaceuticals:​ Active pharmaceutical ingredients (APIs), granules, coated pellets, herbal powders.
      Chemicals & Plastics:​ Resins, pigments, fertilizers, plastic pellets, powder coatings.
      Metals & Minerals:​ Metal powders (iron, aluminum), silica sand, abrasives, foundry sand.
      Others:​ Recycled materials, battery powders, and other fine chemicals.

      Our standard tumbler screening machines can effectively handle screening down to 37 microns (400 mesh), with specialized configurations capable of reaching 25 microns (500 mesh)​ or finer for certain materials. The achievable precision depends on material characteristics like moisture content, shape, and electrostatic properties. We recommend sending us a sample for a free test analysis.

      One of the key advantages of a tumbler screener is its extended screen life. Due to the gentle, rolling motion—as opposed to aggressive vibration—the screen mesh typically lasts 5 to 10 times longer​ than in conventional vibratory sieves. The screen frames are designed for quick changeover, often featuring a quick-release clamp or a pneumatic lifting system, minimizing downtime for maintenance and mesh replacement.

      Yes. Our machines are well-suited for challenging materials. We offer integrated anti-blinding systems​ as options, such as:
      Ball Tray Systems:​ Where rubber balls bounce against the underside of the screen, providing a mechanical cleaning action.
      Ultrasonic Deblinding Systems:​ A high-frequency vibration is directly applied to the mesh, effectively preventing adhesion and clogging for ultra-fine and sticky powders.

      Please inform us of your material’s characteristics so we can recommend the best configuration.

      We provide both. While we have a range of successful standard models (with diameters from 1000mm to 2600mm), we specialize in engineering custom solutions. We can customize the in-feed/out-feed design, the number of decks, the cleaning system, the base frame, and other features to integrate seamlessly into your existing production line or meet unique process requirements.

      Yes, we strongly encourage it. We offer free material testing services​ at our facility or can arrange a test with a local partner. This allows us to determine the optimal machine size, screen configuration, and settings (speed, angle) to achieve your specific grading goals, ensuring the solution meets your expectations.
