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 batch normalization layer, and a …
Shipping by sea currently accounts for more than 80% of global trade volume, with iron ore accounting for the largest solid bulk turnover per year, totaling 1.4 billion metric tons by sea in 2016, mainly from Australia (57%) and Brazil (26%) to China (71%) [1].Brazil is the second largest iron ore exporter and has approximately 7.2% of the world's iron reserves, equivalent to …
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.
