Rotary Vibrating Screen
-
3D Rotary Vibration, High Screening Accuracy: Materials spread evenly without accumulation, realizing high separation purity of fine powder and micro particles with low screen blinding rate, and the grading accuracy exceeds 98%.
-
Fully Stainless Steel & Dust-tight Design: The whole machine is made of 304/316 stainless steel with sealed cylinder to avoid dust overflow, meeting sanitary and environmental standards for food and pharmaceutical industries.
-
Vertical Compact Body, Small Floor Space: Light and compact vertical structure can be directly connected with silos, mixers and packaging machines, greatly improving plant space utilization.
-
Quick Buckle Structure, Time-saving Mesh Replacement: Tool-free quick disassembly design allows mesh replacement within minutes. Residue cleaning is simple to lower daily maintenance cost.
1. Product Overview
Rotary vibrating sieve is a small high-precision 3D screening machine equipped with YZO series vertical vibrating motor as vibration source. The screen box generates three-dimensional rotary vibration including vertical, horizontal and front-back movement. The fully stainless steel sealed structure with multi-layer design can separate multiple particle sizes in one single feeding. It is widely used for fine grading and impurity removal of powder and fine particles, suitable for clean production lines of food, pharmaceutical, chemical and lithium battery industries.
2. Detailed Description
Eccentric weights are installed on upper and lower ends of the bottom YZO vertical vibrating motor. The running motor produces 3D composite excitation force to drive the screen frame for rotary oscillation. Raw materials fall onto the screen surface from the top inlet and stratify quickly under 3D vibration. Fine materials pass through mesh and discharge downward, while coarse impurities flow out from side outlets of the screen frame. Multi-layer screens are optional to realize multi-stage separation, and screening specifications can be adjusted by replacing meshes with different apertures.
3. Materials
Flour, starch, edible sugar powder, pharmaceutical powder, calcium carbonate, quartz powder, lithium battery cathode and anode powder, plastic pellets, resin powder, coating, feed pellets and various fine chemical powders.
4. Why Choose Us
-
3D rotary vibration motion, high precision grading & impurity removal: Vertical vibration motor generates compound vertical, radial and tangential motion; materials spiral upward for full dispersion and screening, achieving fine separation up to 600 mesh with sharp cut points for powder and granular materials.
-
Multi-layer options & compact frame, multi-size separation in one unit: 1 to 5 screen decks available to separate 2~6 particle sizes in a single machine; vertical compact footprint eliminates the need for multiple units in series, ideal for plant retrofits and concentrated process layout.
-
Fully enclosed sealed structure, dust-proof & spill-proof for clean production: Sealed cylinder construction eliminates dust escape and material leakage; 304/316 stainless steel wetted parts optional for food, pharmaceutical and chemical use, meeting emission and GMP sanitation standards.
-
Proven anti-blinding cleaning systems, sustained continuous operation:Available cleaning kits (bouncing balls, ultrasonic, brushes) break up static agglomeration and mesh clogging to maintain throughput, cutting downtime for high-viscosity and agglomeration-prone powders.
-
Flexible mounting & adjustable discharge direction:Isolation springs reduce transmitted vibration for floor or frame mounting; discharge outlets rotate 360° to connect silos, conveyors and packaging machines seamlessly into automated lines.
-
Easy maintenance & low power draw, controllable total operating cost: Integrated vertical motor eliminates complex transmission parts with few wearing parts; adjustable excitation force via eccentric blocks matches working conditions, low power consumption and ≤75dB noise deliver strong economic performance for large-scale deployment.
