1. Overview and Core Positioning​

Yunxi Shaking Table, commonly known as "Yunxi Lab Shaker" or "Yunxi Mineral Processing Shaker" in the Chinese market, is a series of professional vibration-based equipment developed for domestic scientific research and industrial needs. Designed with a focus on precision, durability, and adaptability to local application scenarios, it mainly covers two core categories: laboratory-oriented small-scale shakers and mineral-processing medium-sized shakers.​

Unlike generic international brands, Yunxi Shaking Table emphasizes cost-effectiveness and customization—for example, optimizing parameters for Chinese mineral characteristics (e.g., fine-grained gold ore, tungsten ore) and matching the common container specifications in domestic labs (e.g., 500mL standard flasks, 24-well plates). This localization advantage makes it widely used in universities, research institutes, and small-to-medium mining enterprises across China.​

2. Laboratory-Grade Yunxi Shaking Table (Yunxi Lab Shaker)​

The laboratory-focused Yunxi Shaking Table is primarily categorized as orbital incubator shakers and reciprocating mixing shakers, tailored for life sciences, chemistry, and environmental testing. It stands out for its balance of precision and user-friendliness, meeting the daily needs of most domestic labs.​

2.1 Key Technical Characteristics​

Motion Modes: Dominated by orbital motion (most common) and reciprocating motion, with optional rocking motion for gentle mixing tasks. The orbital amplitude is adjustable between 1–50mm (typical options: 10mm, 20mm, 30mm), while the reciprocating stroke ranges from 10–30mm—suitable for both cell culture and solvent extraction.​

Precision Control:​

Speed range: 50–500rpm, with an accuracy of ±1rpm (supported by brushless DC motors, ensuring low noise <55dB during operation).​

Temperature control: For incubator models (Yunxi-Y series), the range is 5°C above ambient to 60°C, with a temperature uniformity of ±0.5°C (equipped with PTC heating elements and forced convection fans, avoiding local overheating).​

Timer & Alarm: Programmable timer (1min–999h) with auto-shutdown; built-in over-temperature (≥65°C) and overload alarms (exceeding rated load by 20%) for safety.​

Sample Compatibility: The stainless steel tabletop (304 grade, corrosion-resistant) supports loads of 2–15kg, with universal clamps for fixing containers like flasks (50mL–2L), microplates (96-well/384-well), and test tubes. Some models (Yunxi-M series) offer detachable racks for multi-sample simultaneous processing.​

2.2 Typical Laboratory Applications​

Life Sciences: Used for microbial cultivation (e.g., E. coli, yeast) in liquid media—150rpm orbital motion and 37°C temperature maintain oxygen-rich conditions, boosting cell density by 20–30% compared to static culture. It also supports fungal growth (e.g., Penicillium) with optional humidity control (40–90% RH) in high-end models.​

Chemical Experiments: Ideal for solvent extraction (e.g., extracting berberine from Coptis chinensis with ethanol) using 80–120rpm reciprocating motion, shortening extraction time by 30% vs. manual shaking. It also aids in enzyme kinetics tests (e.g., amylase activity measurement) by ensuring uniform mixing of enzyme-substrate solutions.​

Environmental Testing: Mixes water/soil samples with reagents (e.g., heavy metal detection reagents) for rapid analysis—common in environmental monitoring stations for testing lead, cadmium, and other contaminants in groundwater.​

2.3 Localization Advantages​

Cost-Effectiveness: Priced 20–30% lower than imported brands (e.g., Thermo, Eppendorf) with similar performance, reducing the budget burden for small labs.​

After-Sales Service: Domestic warehouses provide quick access to spare parts (e.g., motors, heating elements), with on-site maintenance response within 48 hours in major cities—solving the long wait time issue of imported equipment.​

3. Mineral-Processing Yunxi Shaking Table (Yunxi Gravity Separation Shaker)​

The mineral-processing variant of Yunxi Shaking Table is a gravity separation device optimized for Chinese mineral resources, especially fine-grained non-ferrous metals and precious metals. It is widely used in small-scale mines (daily processing capacity: 5–50 tons) and mineral processing workshops.​

3.1 Structural and Technical Features​

Tabletop Design: Rectangular tabletop (common sizes: 1.2m×0.6m, 1.5m×0.7m) made of wear-resistant rubber or fiberglass (thickness: 5–8mm), with diamond-shaped or linear grooves to guide mineral flow. The incline angle is adjustable (3°–8°) via a manual crank, adapting to different ore densities.​

Transmission System: Driven by an eccentric shaft (eccentricity: 10–20mm) and a 1.5–3kW motor, the table reciprocates at 180–300 times per minute. The vibration amplitude is steplessly adjustable, allowing precise control of mineral migration speed.​

Auxiliary Systems: Equipped with a uniform feed device (to avoid uneven ore slurry distribution) and a multi-point water spray system (water pressure: 0.1–0.3MPa)—the spray nozzles are adjustable to control water flow, ensuring effective separation of light gangue and heavy minerals.​

3.2 Application Scenarios in Mineral Processing​

Precious Metal Separation: Efficiently recovers fine-grained gold (0.074–0.5mm) from placer gold or vein gold ore. In small gold mines in Yunnan and Guizhou, Yunxi Shaking Tables achieve a gold recovery rate of 85–92%, with a concentrate grade improved by 5–10 times.​

Rare Metal Processing: Separates tungsten, tin, and molybdenum minerals from gangue. For example, in southern Jiangxi’s tungsten mines, it processes tungsten ore slurry (after crushing and grinding) to produce tungsten concentrate with a grade of over 65%.​

Non-Metal Purification: Used for purifying graphite, barite, and fluorite—removing quartz and feldspar impurities by density difference, increasing the product’s industrial value.​

3.3 Operational Advantages​

Easy Operation: The control panel uses Chinese labels (with clear icons), making it easy for miners with limited technical background to master. The incline and vibration parameters can be adjusted without stopping the machine.​

Energy Efficiency: The motor power is 20% lower than traditional shaking tables, reducing daily electricity consumption by 3–5 kWh for a 10-ton/day processing line—suitable for mines in remote areas with limited power supply.​
