Knowledge of raw materials for high carbon ferrochrome processing
With the continuous development of social economy, the demand for high carbon ferrochrome rises sharply. Generally speaking, the main method of weight separation for production, the use of shaking table and elimination of separation, sometimes gravity concentrate with weak separation or strong magnetic separation and re-separation, further improve the grade of chromium concentrate ore and ferrochrome ratio. In the actual production of high carbon ferrochrome, it is often necessary to choose the appropriate ore species collocation and the proportion of collocation. High - carbon ferrochrome processing and feeding is also one of the problems that need to be understood.
The high carbon chromite ore is broken between the immovable and movable jaw plates. When the eccentric shaft rotates, the movable jaw plate is made to reciprocate back and forth by connecting rod and push-pull to achieve the goal of pressing ore and discharging. Ore thermal protection requires that the size of coke is smaller than that of ore. The roller crusher can be used to crush the raw materials or coke with small size. After the high carbon ferrochrome raw material is broken, then sieving, through weighing batching, sent to the top of the bin, through the material pipe into the furnace or sent to the feeding platform.
The feeding equipment and weighing need to be simple and reliable. At present, there are two feeding methods: One is to use a belt conveyor to reach the material warehouse, and then arrange the material according to the batching ratio in the batching car to unload the top warehouse. Another way of feeding is to send the furnace section to the roof platform along the inclined bridge with the feeding trolley.
