Rettar has introduced the 3DPro2300 radar scanner for bulk solids inventory management in high-dust silos. The ATEX/IECEx certified system uses 80GHz FMCW radar to provide real-time 3D surface mapping. The Inventory Blind Spot: Why Mass Extrapolation & Single-Point Leveling Fail For decades, mine operators and bulk material handling facilities have relied on mass extrapolation via belt scales or single-point level measurement to estimate inventory. However, calculating theoretical weight or measuring a single vertical distance does not constitute true inventory management. Bulk solids behave unpredictably. Heavy dust generated during crushing, loading, and feeding operations, coupled with variable moisture and material discharge dynamics, frequently complicates the environment inside silos, making it difficult to calculate the volume of materials accurately. When management relies on legacy measurement paradigms, they operate with a critical operational blind spot: * Mass Extrapolation (Belt Scales): Relies on input/output throughput formulas. Cumulative measurement errors compound rapidly over time and fail to account for material compaction or structural hang-ups,…

WtE plants manage diverse bulk materials. Radar scanners, level sensors, and point switches optimize inventory in pits, hoppers, and silos. Waste-to-energy (WtE) plants handle a variety of materials, including incoming waste, combustion residues, flue gas treatment reagents, and leachate. These materials can create different measurement challenges, such as dust, fog, high humidity, material buildup, corrosion, and irregular material surfaces. For this reason, WtE plants often require different monitoring technologies for different process areas. 3D radar scanning, radar level measurement, laser scanning, and point-level switches can be selected according to the material, operating conditions, and monitoring requirements. Monitoring Challenges Across Waste-to-Energy Plants Waste Storage Pits Waste storage pits contain mixed and irregular materials that are constantly changing. Moisture, fog, dust, and odors can also make visual inspection difficult. A 3DPro2300 Radar Scanner can scan the material surface and generate a three-dimensional model, providing information about material height, surface distribution,…

Summer heat makes bulk solids cling to silo walls and distorts inventory figures. Rettar measures the surface without contact using the 80 GHz 3DPro2300 radar scanner, 16,200 points per sweep, ATEX and IECEx certified. Rising seasonal temperatures introduce serious operational challenges across bulk material handling facilities. In agricultural grain silos and industrial coal storage, intense ambient heat combined with fine airborne dust elevates thermal buildup and static explosion risks. Passing strict summer safety audits requires accurate, continuous monitoring without exposing operators to hazardous conditions. Implementing an 80GHz 3DPro2300 Radar Scanner for coal silos and grain processing provides a 3D surface mapping solution that eliminates static risks while ensuring precise bulk inventory tracking. Unseen Hazards Under Extreme Summer Heat Hot summer days change how bulk materials behave inside storage silos. Direct sun bakes steel silo roofs, trapping heat and moisture inside closed spaces. In these conditions, dry grain, starch, and coal dust stick to smooth silo walls. This material clinging forms hidden bridges, holes, and thick crusts that nobody can see from the outside.…

Coal inventory in silos or sheds is challenging due to dust and humidity. 3D laser scanners suit sheds with moderate dust for detailed mapping. 80GHz radar is best for enclosed silos with extreme dust/steam for deep penetration. Keeping track of bulk coal inventory is a persistent operational challenge. In large storage sheds and tall silos, heavy airborne dust, humid vapor, and shifting material piles make accurate volume estimation exceptionally difficult. Measuring these stockpiles precisely is essential to maintain steady boiler feed rates in power plants while protecting silos from structural damage caused by asymmetrical loading. Both 3D laser scanners and millimeter-wave 3D radars offer automated, non-contact volumetric tracking—each excelling in specific plant environments. Key Takeaways: * 3D Laser Scanning: Best for indoor coal sheds and semi-enclosed domes with light-to-moderate dust where high-density spatial resolution and detailed surface mapping are needed. * 80GHz Millimeter-Wave Radar: Ideal for enclosed coal silos with extreme dust, high humidity, and heavy steam due to its superior signal penetration. * Operational Impact: Both technologies eliminate high-risk manual climbing,…

Digital upgrading across heavy industrial sectors highlights a growing necessity for precise inventory tracking, safety monitoring, and automated management. Large storage sheds and raw coal silos require safer and more efficient monitoring solutions. Heavy coal dust clouds, wide temperature variations, and strict explosion-proof requirements frequently challenge field sensors. In these environments, highly irregular material surfaces make precise inventory control extremely difficult to maintain through basic measurement methods. To address these complex physical formations, field-proven radar technology offers an integrated sensing network to transform bulk inventory control from rough approximations into real-time, visual data. Inside massive bulk storage yards, material handling presents a distinct set of operational challenges: Critical Challenges in Inventory Management * Dense Airborne Dust: High dust concentration and wide temperature fluctuations often disrupt optical or acoustic measurement tracking. * Irregular Material Profiles: Different coal types create complex pile formations with unpredictable peaks,…

The Rettar 3DPro2300 Easy Radar Scanner provides automated, non-contact 3D volumetric scanning for bulk materials in silos, overcoming traditional inventory challenges like safety risks and inaccurate measurements, and boosting data transparency. Grain and feed facilities need reliable storage management to protect inventory and running efficiency. Traditional silos face measurement errors, safety risks from manual checks, and slow data flow. Modern grain operators turn to a Smart Manufacturing Solution to upgrade standard inventory checks. The deployment of the Rettar 3DPro2300 Easy Radar Scanner in multi-silo storage facilities provides clear 3D inventory scanning across corn, wheat, and soybean stocks, helping plant managers oversee bulk stock and ensure grain safety. Pitfalls in Grain Storage Silos Modern grain facilities handle large volumes of corn, wheat, and soybean meal daily. Frequent loading creates high airborne dust and irregular surface profiles inside enclosed bins. Basic types of sensors measure only one point on the grain surface, leaving huge blind spots. Manual inventory checks make workers into dangerous high-altitude spaces with hazardous dust. Traditional estimation methods result in inaccurate…
