Circular Swing Screen
-
Low-speed & mild vibration operation, intact materials: Soft swing amplitude fits fragile raw materials such as starch, pills and lithium battery powder, no debris generated during screening for high qualified product rate.
-
Self-cleaning structure to prevent long-term mesh clogging: Rubber bouncing balls equipped under each screen automatically clean mesh holes, realizing stable discharging for continuous production of ultra-fine and slightly sticky powder.
-
Integrated circular structure with superior screening accuracy: Uniform material distribution on circular screen extends screening time, classification accuracy reaches 98%. Multi-layer models can separate multiple particle sizes in one single feeding.
-
Fully closed dustproof design for clean production: Stainless steel complete machine optional with sealed dustproof cylinder to avoid dust overflow, complying with sanitary standards of food and pharmaceutical industries.
1. Product Overview
Circular swing screen is a high-precision screening machine simulating manual shaking. Driven by deceleration eccentric mechanism, the circular screen frame performs compound swing of horizontal rotation and slight vertical motion with gentle vibration. It can be equipped with 1-5 layers of screens, mostly made of 304/316 stainless steel. Featuring high screening precision and low blocking rate, it is specialized in fine classification of ultra-fine powder and fragile materials, widely matched with dust-free production lines of food, pharmacy, lithium battery and fine chemical industry.
2. Detailed Description
The motor transmits power to the eccentric spindle through a reducer, forming a gentle elliptical swing track on the screen surface. Materials spread evenly and stratify slowly on the mesh, fine particles pass through screens and discharge from lower outlets while coarse materials flow out along the screen edge. Built-in bouncing cleaning balls continuously tap the mesh to remove sticky powder, and the soft screening process avoids crushing fragile material particles.
3. Materials
Traditional Chinese medicine powder, flour, starch, sugar powder, essence, pharmaceutical pellets, lithium battery cathode and anode powder, metal micro-powder, resin powder, calcium carbonate, ultra-fine quartz powder, ceramic pigment, fine feed powder and other dry ultra-fine powder & micro granules.
4. Why Choose Us
-
3D circular swing screening, ultra-high precision fine grading: Imitates manual hand-sieving 3D orbital motion, materials spread spirally and layered evenly. Achieves precise grading for 20–400 mesh ultra-fine powder with 90%-99% screening rate, perfectly solving blinding problems of sticky and fine materials.
-
Max circular screening area, doubled high throughput: Full circular screening deck without dead zones, customizable 1-5 layers for 4-7 grade separation. Output is 5-10 times higher than ordinary vibrating screens, ideal for large-batch fine production lines.
-
Low-speed flexible screening, zero material breakage: Eccentric low-speed mechanical drive with mild swing movement avoids high-frequency impact. Fragile grains, pills, crystals and food materials remain intact, greatly reducing waste and improving finished product quality.
-
Totally enclosed dust-free structure, eco-friendly & compliance: Full flanged soft sealing enclosure eliminates powder leakage and dust overflow during operation. Fully compliant with environmental and sanitary standards for food, pharmaceutical and fine chemical clean workshops.
-
Automatic mesh cleaning system, anti-blinding & stable operation: Equipped with bouncing ball and ultrasonic dual cleaning system to keep mesh holes unblocked permanently. Supports 24-hour continuous operation without frequent shutdown cleaning.
-
Low noise & energy consumption, ultra-low maintenance cost: Low-speed transmission reduces component abrasion and noise below 65dB with lower power consumption. Simple daily inspection required, few wearing parts, delivering excellent cost performance for large-scale fine processing lines.
