Size Frequency Distribution machine (VSFD)
The Vision Size Frequency Distribution machine (VSFD) is specifically designed to determine accurate weights and shapes of individual diamonds on-line as they are recovered. This unique feature allows precise auditing and accounting of the recovery process in real time, enabling the metallurgist to analyse, optimise and control the process in ways not possible before. Designed to process at a rate fast enough to keep up with the automated single particle sorters, a continuous stream of data is produced as diamonds are recovered.
The process is hands-off, making it possible to automatically package the goods immediately after analysis without any manual intervention or security risk.
Features and Specifications:
- Throughput: 10 - 20 pps for 1mm particles, depending on feedablility
- Output information per diamond: Weight, volume, sieve size and calliper size
- Output information for batch of diamond: Number of diamonds per sieve class, diamond weight per sieve class, total number of particles and total weight of batch
- Individual Calliper Accuracy: 2% RMS
- Individual Volume Accuracy: 6% RMS
- Distribution Repeatability: At least as repeatable as sieving
