Stainless Steel Rotary Screener

Stainless Steel Rotary Screener is a cylindrical grading equipment constructed from stainless steel materials, designed for particle sizing, scalping, and solid-liquid separation of solid powders. The entire machine utilizes SUS304 or SUS316L stainless steel to resist material corrosion, with polished surfaces to prevent material stagnation. Its screening mesh ranges from 2 mesh to 500 mesh (aperture sizes from 9.5 mm to 0.028 mm), which can be configured according to the particle fineness requirements of different industries. In terms of capacity, based on the machine diameter (ranging from 400 mm to 1500 mm) and the flowability variations of the materials, the hourly processing capability per unit spans from 100 kg to 5 tons.

How does a rotary screen work?

The equipment utilizes a vertical vibration motor as its power source. Eccentric hammer weights are mounted on both the upper and lower ends of the motor shaft. When the motor rotates, these two weights convert the rotary motion into horizontal, vertical, and inclined three-dimensional movements. This three-dimensional motion is then transmitted to the stainless steel screen surface secured on the spring structure. Material enters from the top center inlet and exhibits a spiral movement path that spreads from the center outward across the mesh surface. Fine particles smaller than the mesh aperture pass through the mesh into the lower layer and discharge from the bottom outlet, while oversized particles or agglomerated impurities remain on the screen surface, moving along the path to the edge outlet, completing continuous grading and discharge.

What are the benefits of Stainless Steel Rotary Screener?

Utilizing the Stainless Steel Rotary Screener addresses impurity residue issues in production lines. Its enclosed stainless steel structure minimizes dust emission within workshops, maintaining a clean production environment. Components are secured with quick-release clamps, allowing operators to complete screen replacement or internal cleaning within 5 minutes without complex tools, reducing labor intensity during material changeovers. Meanwhile, bouncing balls are configured inside the mesh frame, which jump up and down to strike the screen surface during operation, breaking the adhesion between powders and reducing blinding caused by static electricity or moisture absorption, thereby maintaining discharge speed during continuous operation.

Note: Some buyers confuse this circular vibrating separator with an industrial rotary drum screen. Drum screens rely on cylinder rotation for coarse screening of large particles like gravel or wastewater, while this Stainless Steel Rotary Screener utilizes vibration principles for precise grading of fine powders within 500 mesh. If you require large-scale industrial drum screens, please contact our engineers for customization.

Stainless Steel Rotary Screener FAQ

Q1: How do I determine whether my material requires SUS304 or SUS316L material?

Answer: This depends on the chemical properties of the material. For non-corrosive general foods (such as wheat flour and coffee bean powder), SUS304 material meets daily hardness and wear requirements. If the material contains high concentrations of free acids, chloride ions, or belongs to corrosive chemicals, SUS316L stainless steel with added molybdenum is necessary to retard the intergranular corrosion rate of the equipment.

Q2: What is the purchase price for a single unit of this equipment?

Answer: This machine does not have a fixed selling price. Its ex-factory price is influenced by a combination of technical factors: including the customized screen diameter, the number of screen layers (ranging from 1 to 5 layers), whether an upgrade to an ultrasonic anti-blinding configuration is needed, and whether a specific brand of explosion-proof motor is designated. Variations exist in material consumption and processing man-hours under different configurations, and specific quotes must be calculated based on engineering drawing requirements.

Q3: How should blinding issues be resolved when screening high-viscosity powders?

Answer: For fine powders with static electricity or high moisture absorption, standard bouncing ball cleaning methods may fail to dislodge the material. In this situation, an ultrasonic cleaning device can be installed on the mesh frame, converting 220V 50Hz electrical energy into 33KHz high-frequency electrical energy. This generates micro-amplitudes on the screen surface via a transducer, breaking up agglomerated powders and resolving mesh blinding issues.

Stainless Steel Rotary Screener Packaging and Shipping

With its corrosion-resistant stainless steel structure and three-dimensional vibration path, the Stainless Steel Rotary Screener serves as equipment for industrial fine powder grading. Through customized combinations of materials, layers, and cleaning devices, this equipment integrates into various powder processing production lines. When choosing equipment, buyers should define the particle size distribution, chemical acidity or alkalinity, and actual hourly capacity required, enabling technical personnel to design corresponding mechanical structural schemes and obtain screening solutions that match long-term production balance.
