Background

What production loses when material quality is seen too late

Sample-based control and visual assessment give a delayed picture. Production continues to operate in a non-optimal mode while the actual flow quality has already changed.

Delayed control

The crushing mode decision is made after the material flow has already changed.

Result: equipment works blindly.

Oversize and foreign objects

Large pieces and foreign objects increase the risk of blockage, damage and unplanned stops.

Result: crusher downtime risk increases.

Resource overconsumption

Excessive crushing increases energy consumption, liner wear and productivity losses.

Result: higher cost for the same volume.

No evidence base

Without an archive of frames and events, it is difficult to identify causes of deviations by shifts, batches and modes.

Result: decisions are made by feel.

Before: after-the-fact control

  • A laboratory sample shows a single point, not the flow dynamics.
  • The operator evaluates the particle-size composition visually and does not see the trend.
  • Oversize and deviations are detected too late.
  • Reports are collected manually, and deviation causes are lost.

After: managed process

  • Material quality is visible in the moment — between samples and shifts.
  • The system shows shares of fine, medium and coarse fractions, trends and anomalies.
  • The operator receives an event before a deviation becomes an accident or defect.
  • The measurement, event and frame archive forms an evidence base.
Solution

Continuous material control in the flow

Algorithms continuously analyze video frames and perform granulometric composition analysis, calculate fraction distribution, detect oversize and foreign objects, determine material volume per unit of time and record flow dynamics.

Results go to the operator and technologist interface, are stored in the archive, used in reports and sent to enterprise systems — SCADA, MES, ERP, BI or other systems via API and industrial protocols.

Output Fraction distribution, D10 / D50 / D90, Dmax, oversize, foreign objects, volume and trends.
For whom operator, technologist, area manager, quality service, industrial automation and production management.

Capabilities

Indicators understandable to managers and technologists

Continuous real-time analysis: from checking material presence and camera status to fraction analysis, oversize detection and control signals.

Granulometric composition

Share of fine, medium and coarse fractions in the flow.

  • distribution by classes and fractions
  • average size and Dmax
  • control signals to equipment

Equipment risks

Events that can lead to an accident, blockage or stop.

  • oversize and dangerous pieces
  • foreign objects
  • deviations from thresholds

Flow state

Factors that affect process stability and measurement quality.

  • material presence
  • volume and load
  • frame quality and optics contamination
Interface and reports

Dashboards, charts, events and confirmation frames

The operator sees alarms and the current picture, the technologist sees distributions and trends, and management sees KPIs by shifts, lines and objects.

Technical implementation

Ready industrial solution with equipment, interface and integration

The solution includes not only algorithms, but also an industrial control point: camera, protective housing, lighting, optics cleaning, computing contour and integration into enterprise systems.

The device includes a machine vision camera with a lens and automatic focus adjustment module, an industrial computing unit, power and temperature control modules, a protective enclosure, and an air-blow and automatic optics cleaning unit. The system is designed for dust, vibration, complex lighting and local data processing requirements. Focus, zoom, exposure and working area can be configured remotely without opening the protective enclosure.

Accuracy and acceptance

Accuracy is confirmed on your material

The system is compared with the customer's reference method: sieve analysis, laboratory data, manual annotation or an approved acceptance program. Final indicators are recorded in the test protocol.

Accuracy depends on material, lighting, layer height, camera angle, reference sample quality and operating conditions.

95%+ target accuracy for determining granulometric distribution under normal equipment operating conditions
from 0.1 mm measurable fraction range is configured for the material, optics, lighting and requirements of the specific control point

Determining rock sizes in conveyor flow

Computer vision algorithms were developed to detect rocks on the belt, track objects in the video stream and build a size distribution.

The system is intended to automate granulometric composition assessment and support mill control based on data from a camera above the conveyor.

Ore particle-size control system

A software and hardware complex was developed for real-time analysis of ore granulometric composition.

The system determines fraction distribution, detects oversize and foreign objects, sends measurement results to industrial control systems and generates control signals to change the crusher discharge gap via Modbus.

Result: operational control of crushed ore size and automatic maintenance of the target size class.
KNAUF • porization • foam generation

Material structure control and comparison with reference

A system was developed for operational analysis of gypsum mass porization and comparison of a sample with a reference image from a camera or microscope.

An additional foam-generation control scenario was developed: evaluating foam characteristics and sending an operator signal when deviations occur.

Result: software solution to reduce the human factor in assessing material structure and quality.
