CRUSHING PLANT PROCESS OPTIMISATION P Svedensten1 ABSTRACT Design of processes in order to fi nd the most ef fi cient solution to a speci fi c task is a dif fi cult problem. Often the number of solutions are large and the optimal solution is therefore diffi cult to identify. Crushing plant process design is no exception from this statement.

 — Slag Atomising Technology (SAT) Slag Atomising Technology is a process that converts molten slag (1300-1350ºC) into small spherical balls with a diameter range of 0.1 to 4.5mm. The process consists of a high speed air blowing system with catalyst and water exposed to the stream of falling molten slag out of a tundish into the yard.

 — Introduction. China is the world's largest steel producer, with the China Iron and Steel Association estimating that the country's crude steel production in 2022 will be 935 million tonnes [Citation 1].Steel slag mainly refers to the blast furnace slag and converter slag produced in the process of iron making and steel making, and with the …

• Electronic control of crusher discharge opening and feed rate. With adjustment of a crusher's discharge opening, as the production continues through an on-line coarse size analysis of the crushed product (digital image analyses). Dance, A. 2001) • More attention is being paid to the impact on crushing circuit design caused by variations

 — After crushing and iron separation (completed by a dry magnetic separator), the steel slag has a particle size in the 0–5 mm. The alkalinity M of steel slag is 3.29, according to the calculation method proposed by Mason (equation (1)) (Mason, 1994). Cement used in this study was an ordinary Portland cement provided by Huaxin Cement …

2. Crushing. The jaw crusher is used for coarse crushing, and the hammer crusher is used for secondary crushing, so as to reduce the slag particle size step by step and improve the metal separation rate. 3. Magnetic separation. After screening, the metal part of the slag will be transported to the magnetic separation equipment for magnetic ...

This is the water-jet process. Second, in the machine process, the molten slag is rapidly agitated with a controlled amount of water. Steam is entrapped and there is also some formation of gases due to chemical reactions of some slag constituents with water vapor. With both these methods, crushing of the expanded slag is required.
