vibratory screening for lab

Addressing Critical Laboratory Screening Bottlenecks

In laboratory settings for mining, chemical, and pharmaceutical development, inefficient particle separation creates significant operational and financial impacts. Industry data indicates that laboratories performing vibratory screening for lab analysis lose an average of 15-20 hours per month to manual sieving, sample cross-contamination cleanup, and equipment recalibration. This directly delays quality control results, process development timelines, and final product release.

Are your R&D and QC processes constrained by these common challenges?

• Inconsistent Results: Manual sieve shaking and low-grade equipment produce variable data, compromising the reliability of your scale-up models.
• Sample Contamination: Difficult-to-clean screens and open-frame designs risk material carryover between batches, invalidating entire test sequences.
• Operator Fatigue & Time Loss: Repetitive manual screening tasks occupy highly skilled technicians, diverting them from higher-value analytical work.
• Excessive Noise & Dust: Standard industrial screens are often unsuitable for controlled lab environments, creating safety and housekeeping issues.
• Data Gaps: Lack of repeatable process parameters makes it difficult to correlate lab-scale findings with full-scale production performance.

Product Overview: Lab-Precision Vibratory Screening System

The Lab-Precision Vibratory Screening System is engineered specifically for high-accuracy particle separation in research, development, and quality control laboratories. This system delivers the repeatability required for dependable data generation.

The operational workflow is streamlined for efficiency:

1. Sample Loading: The operator places a prepared sample into the top of the sealed screening assembly.
2. Parameter Setting: Key variables—screening duration, amplitude, and frequency—are input via the digital control panel for consistent, repeatable operations.
3. Automated Separation: The system executes the cycle, utilizing controlled vibratory motion to stratify and separate particles through the selected screen stack.
4. Disassembly & Analysis: The quick-release clamp mechanism allows for fast disassembly. Each fraction is collected for weighing and analysis with minimal loss.
5. Cleaning: The easily removable screen frames facilitate rapid cleaning to prevent cross-contamination.

Application Scope: Ideal for particle size distribution (PSD) analysis, quality assurance of incoming raw materials, and process optimization studies in mineral processing, pharmaceuticals, ceramics, and chemical industries.

Limitations: This system is designed for dry or minimally moist materials in a laboratory environment. It is not intended for abrasive-slurry applications or continuous 24/7 production-scale duty.

Application Scenarios

Mineral Processing R&D Lab | Challenge: A mineral processing lab needed reliable PSD data to optimize their flotation circuit but faced high variability (+/-10%) from manual sieve analysis across different technicians. This unreliable data led to poor predictive models for full-scale plant performance. Solution: Implementation of a standardized vibratory screening for lab protocol using the Lab-Precision system with stored digital parameters. Results: Achieved a repeatability variance of less than +/-2%. This high-fidelity data improved their flotation recovery prediction model accuracy by over X%, leading to more confident plant-scale adjustments.
