Rettar's multi-scanner system precisely measures bulk coal stockpiles in large sheds. Coordinated sensors provide comprehensive mapping for accurate volume estimation. Thermal power plants rely on effective fuel supply and inventory management to maintain stable operations throughout the year. Inside massive coal sheds, stacker-reclaimers continuously build and reshape stockpiles, creating irregular ridges, steep slopes, and uneven surfaces. Variations in humidity, material characteristics, and operating conditions can further complicate stockpile management. The challenge is not simply measuring the distance between a sensor and the coal surface. It is determining how much coal is stored across an extensive area. A single distance sensor captures only a limited perspective, making it difficult to represent an entire stockpile accurately. Rettar's multi-scanner system addresses this limitation through coordinated measurements from multiple positions. Coal Inventory Measurement Challenges in Large Coal Sheds Several practical challenges can undermine coal inventory measurement. * Irregular stockpile geometry. Stacker-reclaimers create…

Traditional silo level measurements are inaccurate due to dust, buildup, and uneven surfaces. 3D mapping accurately measures bulk volume for better inventory. Reliable inventory data is the backbone of efficient feed production. However, traditional level measurements often fail to reveal the actual quantity of material inside a silo. Irregular filling patterns, heavy dust, material buildup, and uneven surfaces distort conventional readings, creating significant blind spots for feed manufacturers handling abrasive bulk materials in enclosed environments. While traditional point-level switches and single-point transmitters indicate general status, they cannot reconstruct the complete material surface. 3D material mapping offers a comprehensive solution, capturing true bulk volume to drive more informed supply chain decisions. The Hidden Challenges Inside Feed Silos Feed silos rarely contain flat material surfaces. Material accumulates unevenly during filling, shifts during discharge, and forms slopes or irregular contours that skew standard measurements. Key operational challenges include: * Heavy dust: Airborne particles interfere…

Rettar's Na22 Density Meter measures abrasive, high-viscosity tungsten slurry in a vertical pipeline without contact: clamp-on mounting, energy spectrum detection, accuracy of ≤ ±1% and an exemption-level source below 1,000 kBq. Reliable slurry density measurement is essential for process monitoring in mining and mineral processing. However, highly abrasive materials, high viscosity, and challenging pipeline configurations can make stable, representative measurements difficult to achieve. In this tungsten ore processing application, the material was fine slime—a high-viscosity slurry containing extremely fine, abrasive particles—flowing vertically downward through a pipeline. These conditions demanded a measurement solution that could address material wear, flow-related uncertainty, and operational safety without disrupting the production process. The Na22 Density Meter combines non-contact clamp-on installation, advanced energy spectrum detection, and an exemption-level gamma radiation source to address these application requirements. High-Viscosity, Abrasive Tungsten Slurry Avoiding Wear and Clogging Tungsten ore fine slime presents significant challenges for conventional wetted sensors.…

Conveyor scales and point sensors create false bulk solids inventory in silos. Rettar's 3D radar maps the full material surface for precise volume. The Inventory Illusion: Why Scale Calculations Leave You Blind Relying purely on conveyor belt scales to track silo stock creates a dangerous tracking illusion. On paper, your numbers balance. In reality, two major issues are constantly throwing off your inventory: * Scale Drift & Belt Tension: Moisture, material buildup on rollers, and mechanical belt stretch create small hourly errors. Over a week, these "tiny" errors snowball into massive accounting variances. * Unseen Surface Topography: Scales can’t see what’s happening inside the silo. Material rarely stacks in a perfect, symmetrical cone. Single-point radar sensors don't help much either—they only measure distance to a single spot on a complex, uneven pile, leaving massive volumetric blind spots. The Bottom Line: When you manage inventory by calculating mass flow instead of measuring the actual physical heap inside, you're managing blindly. Operations are often forced to take massive quarterly write-offs…

Rettar's 80GHz 3D mmWave radar sees through coal dust and steam and measures true volume in silos, sheds and stockyards 24/7, without manual surveys or single-point errors. Real-Time Bulk Inventory Challenges in Heavy Mining & Coal Operations Maintaining accurate bulk material inventory across coal sheds, blending yards, and storage silos is a critical challenge for modern mining operations. Plant managers depend on precise real-time volume and tonnage metrics to control coal blending ratios, optimize plant throughput, and satisfy accounting audit requirements. However, acquiring reliable real-time inventory data in high-dust environments remains difficult: * Manual Surveying Risks: Traditional survey methods using manual laser rangefinders or drones require halting material handling. They put personnel into dangerous, confined high-dust zones and only yield delayed, non-continuous static reports. * Optical & LiDAR Limitations: Optical LiDAR scanners installed overhead frequently fail in mining applications. Suspended coal dust, iron ore fines, and ambient steam quickly coat optical lenses, causing severe measurement drift or total system…
