Stone Production Line Is Used for Crushing Scrap Iron


In terms of the scrap stone production line, the manufacturing technology is very complex and the production costs are high. However, since the advanced technology, wide processing range and high productivity, the stone production line is relatively ideal equipment for processing the scrap iron and the steel. In addition, the stone production line can select the non-ferrous metals, exclude non-metallic debris and process the high-quality scrap steel with high purity. The environmental pollution is also small in the process of the stone production line, so it is known as the current advanced processing equipment for processing the scrap steel and the iron.
At present, there are already nearly more than 700 scrap steel stone production line running around the world. The broken steel into the furnace proportion rises rapidly. The proportion in some countries has reached more than 45%. The stone production for crushing and screening the scrap iron and steel produced by Henan Hongxing Mining Machinery is suitable for the production of high-quality metal charging used for the electric furnace and the converter steelmaking.
Fist, we can crush the thin and light scrap iron whose thickness is below 6mm into the fragments whose length is not more than 150mm. Then we should remove the non-ferrous metal, alloy metal parts and the non-metallic impurities in the scrap iron and steel. The scrap steel crushing and screening stone production line includes the crusher machine, the hammer clastic machine, rotary screen, tumbling rotary kiln, preloading means and the conveyor system. The working sequence of the stone production line is as the followings. The electromagnetic grab crane is used to send the large thin scrap steel into the charging chute of the crushing machine. In the charging chute, the materials are pre-crushed into the material block whose size is not more than 800mm. The scrap steel is rotated by the rotating crushing machine and they are crushed by the star wheel. Then the materials fall on the plate conveyor evenly along the charging wash tank. The materials are transferred to the crusher. The scrap steel which falls in the classtic machine is crushed by the hammer with high rotating speed. The small pieces of scrap steel after being crushed enter the belt conveyor along the bottom screen bars of the crusher.
In the crushing process, the small impurities and other non-metallic impurities are screened out. The adjustable speed electric drive device is installed in the conveyor to guarantee the normal work of the crusher transmission.
