Product Overview
The Ruidi Vibratory Sieve is a compact three-dimensional rotary vibrating screen, specially designed for laboratory testing, sample screening and small-batch industrial production. This mini sieve machine adopts classic 3D vibration principle, which can efficiently screen, grade, remove impurities and filter dry powder, fine granules and low-viscosity liquid materials.
With a compact body and lightweight design, it occupies minimal workshop space and can be moved freely. The whole machine features fully sealed structure to prevent dust leakage and material splashing. It is widely applicable to food, pharmaceutical, chemical, rubber, cosmetic and new material industries, becoming the cost-effective screening solution for small factories, R&D laboratories and pilot production lines.
Core Matching: Suitable for raw materials with particle size below 10mm, supporting mesh range from 2 mesh to 400 mesh to meet high-precision fine screening demands.
Core Advantages
✅ Compact & Space-Saving Design
Mini overall structure, small footprint and light weight. No special foundation required. It can be placed on any flat ground and moved easily, perfect for narrow workshops and laboratory environments[7].
✅ 3D Rotary Vibration & Anti-Clogging Performance
Equipped with a high-stability vibration motor to generate uniform three-dimensional circulating vibration. The unique motion track effectively avoids mesh blockage caused by fine powder and sticky materials, keeping stable screening efficiency for long-time operation[7].
✅ Full Dust-Proof & Sealed Structure
Integrated fully enclosed cover prevents dust flying and liquid splashing during operation. It avoids raw material waste and creates a clean, safe working environment, complying with basic industrial hygiene standards[6].
✅ High Screening Precision & Wide Adaptability
Supports 2–400 mesh multi-level screening, applicable to particles, powder and liquid materials within 10mm. Screening accuracy reaches over 95% for impurity removal and material classification[11].
✅ Easy Operation & Low Maintenance
Plug-and-play design, simple operation without professional training. The screen mesh can be replaced in 3–5 minutes without tools. Low noise and low power consumption, supporting 24-hour continuous production.
✅ Durable Material & Multiple Optional Screens
Material contact parts adopt high-quality anti-corrosion material. Standard equipped with stainless steel woven mesh and nylon mesh, optional PU screen for sticky and wet materials. Wear-resistant structure extends service life[3].
✅ Flexible Customization Available
Support customized screen layers, working voltage, body color and discharge direction to adapt to different regional power standards and production requirements worldwide.
Working Principle
The ruidi vibratory sieve uses a vertical vibration motor as the vibration source. The eccentric hammers installed on the top and bottom of the motor convert the rotating motion into horizontal, vertical and inclined three-dimensional movement. The vibration is transmitted to the screen surface, so materials move along a circular trajectory on the sieve. By adjusting the angle of eccentric hammers, users can change the material movement track to achieve ideal screening and grading effects.
