Square Swing Screen
-
Low-speed & low-noise swing, no material damage: Low-speed operation brings slight vibration, no breakage of brittle and fragile materials to guarantee finished product integrity.
-
Excellent mesh cleaning, anti-blocking design: Built-in bouncing cleaning balls continuously clear tiny mesh holes, preventing clogging during long-term screening of starch, resin powder, metal micro-powder and other fine materials.
-
Multi-layer classification with high screening accuracy: Up to 6 layers of screens for simultaneous separation with classification accuracy over 98%, meeting refined sorting requirements of high-end powder.
-
Fully sealed sanitary structure, meeting clean production standards:304/316 stainless steel optional for the whole machine, closed dustproof housing without dust leakage, suitable for dust-free workshops of food and pharmaceutical industries.
1. Product Overview
Square swing screen is a fine screening device simulating manual reciprocating swing. Driven by reduction motor, the screen frame performs compound swing with horizontal and slight vertical movement, operating smoothly without high-frequency impact. It can be equipped with 1–6 layers of screens, mostly made of full stainless steel. It boasts high screen utilization rate and low mesh blocking rate, specially designed for high-precision classification of fine powder and micro-granules, widely used in clean production lines of food, medicine, chemical industry and new energy powder.
2. Detailed Description
The drive system outputs low-speed balanced swing force through eccentric transmission mechanism, forming an elliptical smooth movement track on the screen surface. Materials spread and layer slowly on the screen, fine powder penetrates the mesh while coarse materials move forward to discharge outlets. The gentle screening mode will not damage material particles. Elastic cleaning balls continuously beat the screen to effectively avoid mesh clogging caused by fine sticky powder.
3. Materials
Flour, starch, xylitol, traditional Chinese medicine powder, chemical micro-powder, lithium battery cathode & anode materials, resin powder, metal powder, quartz powder, calcium carbonate, fine feed powder, essence and other dry fine powder & ultra-fine granular materials.
4. Why Choose Us
-
Imitation manual swing screening, ultra-precise fine classification:Eccentric linkage drives low-speed planar swing, materials spread evenly for full stratification; superior accuracy for sticky fine powder, effectively preventing mesh blinding and mixed grades.
-
Large effective screening area, high throughput with compact footprint: Multi-layer stacked square screening deck maximizes usable area, higher output under same floor space than circular vibratory sifters, ideal for continuous mass production lines.
-
Low-amplitude low-speed gentle screening, zero breakage for fragile materials: Gentle low-speed swing without high-frequency impact; intact grains, pellets, pills and resin particles, raise yield and cut material loss.
-
Fully sealed dust-proof design, eco-friendly for clean workshops:Fully enclosed dust cover with soft gaskets eliminates powder leakage, meets environmental standards for food, pharmaceutical and fine chemical clean workshops.
-
Snap-in quick-release screens, all-stainless sanitary & easy washing: Tool-free snap screens for fast replacement, no sanitary dead corners; 304/316SS contact surfaces standard, easy washdown for frequent material formula switching.
-
Low noise & wear, low long-term maintenance cost: Low-speed mechanical drive reduces component abrasion, extended service life for wearing parts; noise ≤68dB, only regular greasing required, cost-effective for large-scale production.
