Selection of high carbon chromite ore
With the continuous development of social economy, the demand of high carbon ferrochrome increases sharply. Generally speaking, the main use of gravity separation method for production, the use of shaking table and elimination of separation, sometimes gravity concentrate with weak separation or strong magnetic separation re-separation, further improve the grade of chromic ore and ferrochrome ratio. In the actual production of high carbon ferrochrome, it is often necessary to choose the appropriate mineral collocation and collocation ratio. And high carbon ferrochrome processing feeding is one of the problems that need to be understood.
High carbon ferrochrome ore is broken between the movable jaw plate and the movable jaw plate. When the eccentric shaft rotates, the movable jaw plate is moved back and forth through the connecting rod and push-pull to achieve the purpose of pressing ore and discharging ore. Mineral thermal protection requires coke particle size is smaller than ore. For smelting requirements of small granularity of raw materials or coke can be broken by the roller crusher. After crushing, high-carbon ferrochrome raw materials are screened, weighed and batched, sent to the top silo of the furnace, and then added to the furnace through the feed pipe or sent to the feeding platform.
Feeding equipment and weighing need to be simple and reliable, the current feeding methods have the following two: one is to use the belt conveyor to material to the silo, and then according to the ratio of the material in the batching car will be matched with the unloading furnace top silo. The other feeding method is to send the furnace to the top platform along the inclined bridge by the feeding trolley.
