Abstract: An improved U-Net based convolutional neural network (CNN) is proposed in this paper for online size monitoring of iron ore pellets. The proposed CNN model is a lightweight version of U-Net. In the proposed model each convolution block of the encoder subnet consists of a concatenated $1times 1$ and $3times 3$ filter kernel, a …

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.

For each sieve-size frame, the pellets were spread across the sieve mesh with a hand brush, and the frame was shaken to resolve individual pellets that stuck in the sieve mesh. The sample of baked iron ore pellets was sieved into six sieve-size gradings. Sieve-size frames of 6.3, 9, 10, 11.2, 12.5 and 14 mm were used.
