Shape analysis of particles with HAVER Computerized Particle Anaysis Technology

HAVER & BOECKER is internationally know as manufacturer of systems, machines and sieve media for generations. This experience and a wide know-how of our engineering specialists provided the ideal conditions for development of a new technology in the early 90s: the Computerized Particle Analysis for particle size and particle shape analysis of dry and non-agglomerating bulk material with the dynamic image analysis.

Today HAVER CPA systems for Dynamic Image Analysis (DIA) provide shape analyses with standardised units and customised inline and online solutions with dynamic image analysis for the largest abstract measuring range from 10 micron up to 400 mm. All particles of a sample which lie within the measuring range are analysed and counted in real time due to the approved line scan camera.

HAVER Computerized Particle Analysis Technology for shape analysis

The HAVER CPA measuring process for Dynamic Image Analysis (DIA) is used for the shape analysis of grain of dry and non-agglomerating particles of bulk materials. When fitted with the appropriate HAVER peripherals, this process of shape analysis using the dynamic image analysis can be used as a laboratory, technical centre or online version in different fields: gravel, sand, coke, coal, plastic granules, wood chippings, chemical and pharmaceutical products, fertilizers, foodstuffs and many more.

All HAVER CPA (Computerized Particle Analysis) systems use the dynamic image analysis for digital image processing for the shape analysis of particles. A sample of the material is transported on a feeder to the measurement channel to achieve an optimal metering. A high-resolution digital line scan camera scans the particles in free-falling bulk materials against the background of an LED lighting array. The scanned lines are combined by the CPA to form an endless data record and the shadow projections of the particles are evaluated in real time. The vertically unlimited images of the line scan camera enable such a REAL TIME measurement of the shape analysis and thus the use of all CPA units as particle counting devices.

The line scan camera provides further advantages for the shape analysis: double detection due to individual images overlapping is ruled out, as are partial range detection and mis-measurement of truncated particles.

Furthermore the shape analysis allows the application with conveyors. So the HAVER CPA CONVEYOR systems provide highly precise measurements of e.g. longish materials and best reproducibilities also with small sample quanities.
