Colorbiotics GEM Vision Brings Laser Measurement to Aggregate Conveyors

Colorbiotics GEM Vision Brings Laser Measurement to Aggregate Conveyors

Measuring the volume of material travelling along a conveyor belt sounds straightforward until the flow becomes irregular. Mulch, wood chips and aggregates rarely move in uniform quantities, and gaps between loads, changing belt speeds and uneven material profiles can complicate production records. Colorbiotics, a Sika brand, has introduced a laser-based measuring system designed to address these conditions without interrupting processing operations.

Called GEM Vision, the system uses dynamic laser scanning to measure the volume of material passing along a conveyor. Developed for grinders, screening plants and material colouring equipment, it provides continuous production information through a local control panel or remotely on connected devices.

The technology is available as a standalone system for installation on existing equipment or as an option on new Sahara machines from Colorbiotics, bringing automated volumetric monitoring to operations that may otherwise rely on periodic measurements or estimates of material throughput.

Briefing

• Colorbiotics, a Sika brand, has introduced GEM Vision, a laser-based volumetric measurement system for conveyor-fed equipment.
• Dynamic belt scanning is designed to accommodate irregular material profiles, varying conveyor speeds and gaps in material flow.
• Built-in filtering addresses vibration, reflections and other potential sources of measurement interference.
• Production data is available locally and remotely, with batch control supporting inventory records and truck loading.
• GEM Vision can be retrofitted to existing grinders, screeners and colouring systems or supplied on new Colorbiotics Sahara machines.

Measuring Material in Motion

Conveyor belts rarely carry a perfectly uniform stream of material. Wood chips and mulch can arrive in uneven quantities, leaving gaps between successive loads or building up into irregular profiles across the belt. Crushed aggregates present similar challenges, particularly where feed rates fluctuate during screening or processing.

Estimating throughput from a conveyor’s nominal capacity or an assumed material profile may therefore produce figures that differ from the quantities actually handled. GEM Vision addresses this by scanning the material as it travels along the belt, rather than relying on a fixed profile or an assumed rate of flow.

Colorbiotics says the system accommodates variations in belt speed and material shape, with built-in filtering intended to reduce interference from vibration, reflections and other operating conditions that could affect measurement.

Jerry Everett, process technology manager at Colorbiotics, explained the approach: “The GEM Vision offers a higher accuracy level because of the use of a dynamic belt scan,”

Everett, added: “It has built-in filters for vibration, reflection and other contamination that can happen on a conveyor belt system, and it accounts for inconsistent flow when there are gaps across the belt.”

The company has not published a numerical accuracy tolerance, repeatability figure or independent validation results in its announcement. Details of calibration requirements and operating limits are also unavailable, making direct performance comparisons with established conveyor measurement technologies difficult at this stage.

Production Control and Inventory Management

GEM Vision extends beyond displaying the volume of material passing along a conveyor. Production data can be viewed through the equipment’s control panel or accessed remotely on connected devices, allowing a loader operator to monitor material movement without repeatedly returning to the processing machine.

Colorbiotics also identifies automated batch control among the system’s functions, supporting the tracking of material flows, inventory and truck loads. The announcement does not specify how the measurement system interfaces with conveyor drives or other plant controls, although the combination of volume monitoring and batch records could be useful in operations handling multiple products or processing runs.

In a mulch colouring plant, for example, reliable records of the volume passing through the equipment could help operators reconcile production with stock movements and outgoing deliveries. Screening and grinding operations face similar requirements when comparing material processed with quantities dispatched or held in storage.

There is an important distinction between measuring volume and establishing weight. A cubic metre of material does not necessarily represent a consistent mass, particularly when bulk density changes with particle size, compaction or moisture content. GEM Vision is presented as a volumetric system, so applications requiring quantities expressed in tonnes would still need an appropriate density conversion or separate weighing equipment.

That consideration is especially relevant to construction aggregates, where commercial transactions and transport limits frequently depend on weight. Continuous volume measurement can contribute to production records without necessarily replacing weighbridges or belt weighing systems.

Retrofitting Existing Processing Equipment

Colorbiotics is offering GEM Vision as a standalone system that can be incorporated into existing grinders, screeners and colouring equipment, alongside its availability on new Sahara machines.

For operators with established processing lines, retrofitting provides a route to production monitoring without replacing the underlying machinery. Installation requirements will nevertheless depend on the conveyor arrangement, available mounting space and compatibility with existing control systems, none of which has been detailed in the announcement.

The operating environment will also influence how measurement equipment performs over time. Aggregate processing and recycling plants can expose conveyor-mounted instruments to dust, vibration and changing material conditions. Colorbiotics specifically identifies vibration and reflection as sources of interference addressed by its filtering technology, although environmental protection ratings, maintenance requirements and recommended installation conditions have not yet been disclosed.

Applications Across Bulk Material Processing

Headquartered in Ames, Iowa, Colorbiotics supplies colourants, surface materials and processing equipment, including its Sahara range of machinery. The company operates as a Sika brand within Sika USA.

Its established involvement in landscape material colouring provides an immediate application for GEM Vision, where knowing the volume of material passing through a processing line can assist with production records, batching and dispatch.

The same measurement principle could have applications in construction materials processing, recycling and other conveyor-fed bulk handling operations. These environments frequently involve irregular feed rates and materials whose physical characteristics change between production runs, although suitability would need to be established for each application.

The potential range of uses extends beyond Colorbiotics’ existing equipment portfolio, but the practical performance of GEM Vision across different materials and conveyor configurations remains to be demonstrated through published specifications or operating results.

For processing operations already using conveyor-fed equipment, the attraction is straightforward: a continuous record of how much material has passed through the system, available to operators without stopping production. How accurately GEM Vision delivers that information under different operating conditions will determine where the technology finds its strongest applications.
