Embodiment 1
[0030] A method for real-time circulating iron removal and grinding of steel slag, comprising the following steps:
[0031] (1) Feeding and iron removal: After the steel tailing slag particles with a maximum particle size of about 100mm are transported to the raw material warehouse by the unloading truck, they are sent to the receiving bin by the loader, and a suspension broadband iron remover is used on the conveyor belt to carry out a process. Removal of iron, after removal of large metallic iron (iron-rich product ①), the primary product of steel slag is obtained;
[0032] (2) Coarse crushing and iron removal: Use a vibrating screen to screen the steel slag primary product described in step (1), and screen out the first steel slag powder with a particle size of 0-18mm and the first coarse steel slag powder with a particle size ≥ 18mm. Granular steel slag, so that the screened first steel slag powder enters the subsequent fine crushing system; the second coarse steel slag is...
Embodiment 2
[0037] A method for real-time circulating iron removal and grinding of steel slag, comprising the following steps:
[0038] (1) Feeding and iron removal: After the steel tailing slag particles with a maximum particle size of about 100mm are transported to the raw material warehouse by the unloading truck, they are sent to the receiving bin by the loader, and a suspension broadband iron remover is used on the conveyor belt to carry out a process. Removal of iron, after removal of large metallic iron (iron-rich product ①), the primary product of steel slag is obtained;
[0039] (2) Coarse crushing and iron removal: use a vibrating screen to screen the primary steel slag product described in step (1), and screen out the first steel slag powder with a particle size of 0-20mm and the first coarse steel slag powder with a particle size ≥ 20mm. Granular steel slag, so that the screened first steel slag powder enters the subsequent fine crushing system; the second coarse steel slag is...
Embodiment 3
[0044] A method for real-time circulating iron removal and grinding of steel slag, comprising the following steps:
[0045] (1) Feeding and iron removal: After the steel tailing slag particles with a maximum particle size of about 100mm are transported to the raw material warehouse by the unloading truck, they are sent to the receiving bin by the loader, and a suspension broadband iron remover is used on the conveyor belt to carry out a process. Removal of iron, after removal of large metallic iron (iron-rich product ①), the primary product of steel slag is obtained;
[0046] (2) Coarse crushing and iron removal: use a vibrating screen to screen the primary steel slag product described in step (1), and screen out the first steel slag powder with a particle size of 0-20mm and the first coarse steel slag powder with a particle size ≥ 20mm. Granular steel slag, so that the screened first steel slag powder enters the subsequent fine crushing system; the second coarse steel slag is...
