A cone crusher is generally used as a secondary crusher in a crushing circuit.
The slag mainly consists of calcium, iron, silicon, magnesium and a small amount of aluminum, manganese, phosphorus and other oxides. In some areas, the slag also contains little titanium and vanadium because of the ore containing those ingredients. Slags are greatly different due to the various components in steel-making furnace, steel furnace steel smelting and each different stage of the smelting process. The application of the crusher has brought new hope to the slag processing.
The approach to dealing with the slag uses the slag and the primary slag as raw materials. The processing technology includes cold abandoned method; hot pour method, splashing cold plate method, water quenching method. Generally, it uses a closed loop production process which is respectively composed by the process of crushing and screening, vacuum ball milling, classification and wind dry magnetic separation to receive four high-quality and high value-added products, which namely means that the steel scrap with a iron content greater than 90 % of high-quality can be used for high-grade iron powder iron that can be used as a cement and concrete admixture of high activity for high-grade steel slag powder and the road surface of asphalt concrete surface layer of steel slag aggregate. After the entire production process completed, it can achieve zero emissions slag with no pollution.

Both processes of crushing and grinding are suitable for the mineral particle size of more than 5cm, which is before ore dressing process flow. And crushing process mainly handles large pieces of ore. Grinding treatment is especially for smaller mineral particles. Because mineral particles in the ball mill was broken at random, the broken probability is very low, studies have shown that the broken probability is less than 10% in the ball mill.
Roads and railways built can’t be separated from the sand and gravel aggregate, the demand for sand and gravel production line has increased. Sand and gravel production line is generally composed by the feeder,and centrally electric control devices. The process is reasonable and gathering feeding, crushing, screening, conveying as a whole. After processed, the finished product quality can be up to GB14685-2001 standard, which is qualified for the express way, rail, water, concrete mixing plant industries aggregate.
