Product Overview
Ruidi linear vibrating screen adopts two counter-rotating synchronous vibration motors as the excitation source, generating continuous linear throwing motion to push materials forward evenly on the screen surface. It realizes automatic grading, impurity removal and dewatering of granular & powdery materials in one continuous operation.
Compared with circular vibrating screens, our linear model performs better for wet, sticky, high-yield bulk materials, featuring large processing capacity, high screening efficiency up to 96%, low noise and easy maintenance. We support fully customized dimensions, layers, outlet directions and materials (carbon steel / food-grade 304 stainless steel) to match different industrial working conditions.


Core Advantages
✅ Large-Capacity Continuous Processing Equipped with twin synchronized vibratory drives and an elongated screening surface, this unit delivers steady material conveyance without pile-ups. Its robust hourly throughput enables seamless inline connection with crushing, pelleting and packaging gear to realize fully automated round-the-clock sorting workflows.
✅ One-Pass Multi-Grade Fractionation Configurable with 1 to 5 screening tiers fitted with dedicated discharge spouts, the unit sorts materials into distinct particle fractions in a single pass. It eliminates the need for multiple standalone sieving machines, cutting workshop footprint and extra equipment investment.
✅ Enclosed Dust-Free Working Structure A fully covered housing paired with flexible sealed joints eliminates airborne powder spillage during operation. It curbs raw material waste while complying with emission regulations for food, chemical and rubber processing facilities.
✅ Reinforced Frame for Nonstop Heavy-Duty Runs The screen box adopts integrally welded thick steel sheets to resist structural distortion under heavy feed loads. High-resilience rubber vibration dampers suppress operating noise and vibration, supporting uninterrupted 24-hour industrial production.
✅ Tool-Free Rapid Screen Swap Mechanism Quick-release side clamps enable effortless screen dismounting without specialized tools. A single operator can complete mesh replacement within 5–10 minutes, drastically minimizing production halt time and labor expenditure.
✅ Targeted Body Material Customization Standard painted carbon steel suits universal screening scenarios; SUS304 or SUS316 contact surfaces are optional for food batches, rubber powders and corrosive chemical feeds, featuring anti-adhesion properties and effortless sanitation. We also tailor overall dimensions to match your plant layout constraints.
✅ All-Round Customizable Configurations Adjustable frame length, mesh aperture, discharge elevation, deck inclination, explosion-proof vibrators and feed hoppers are offered to accommodate unique material traits and on-site installation conditions.
✅ Cross-Industry Versatile Applicability It fits the grading demands of diverse raw materials, including rubber crumbs, carbon black, quartz sand, ores, cereals, plastic pellets, animal feed and construction powders, serving as a universal sorting solution for various production pipelines.
Working Principle
Two symmetric horizontal vibration motors act as vibration source. The rotation of eccentric blocks generates directional linear excitation force to drive the whole screen body for reciprocating linear motion. Materials evenly fall onto screen deck from feeding inlet and slide forward smoothly under linear vibration. Fine particles smaller than mesh aperture pass through screen and discharge from lower outlets; oversized coarse material moves to end outlet. Multi-layer mesh realizes multi-size separation in one cycle. Adjust eccentric block angle to control material conveying speed for dry, wet, light or heavy materials.

FAQ
Q1 What is the difference between linear vibrating screen and rotary vibrating screen?
A: Linear vibrating screen adopts dual-motor straight-line motion, supports large throughput, suitable for coarse particles, wet materials and mass continuous production. Rotary vibrating screen is circular motion, small output, mainly for ultra-fine powder high-precision screening with low hourly capacity.
Q2 Can this machine handle sticky wet materials without mesh blocking?
A: Yes. We can install bouncing cleaning balls inside the screen frame, or equip wear-resistant PU screen panels to effectively prevent mesh clogging. We will adjust vibration amplitude and screen angle according to your material moisture and viscosity.
Q3 Do you support food-grade stainless steel version?
A: Definitely. Full SUS304 linear screen with mirror polished screen box, no dead corners, meets food and pharmaceutical hygiene standards, can provide FDA related material test reports upon request.
Q4 What documents can you provide for customs clearance?
A: We can offer commercial invoice, packing list, bill of lading, CE certificate, ISO9001 certificate, machine dimension drawing, English operation manual, material test report.
