Ferroalloy briquette is made of metal slag or powder, which is a by-product of ferroalloy production. Briquette products have different names according to their chemical elements. For example, silicon briquette (requiring Si content), high carbon silicon alloy briquette, silicon carbide briquette, ferrosilicon briquette, etc. According to their chemical element content is different, its grade is different. For example, 50/10 high carbon silicon briquette (Si≥50% C≥10%) and so on.
According to the requirements of the customer's content index, the required raw materials are manually matched, the large-scale preparation after the test is qualified, and then the automatic feeding machine ingredients, through the conveyor belt to the automatic ball press equipment production line in accordance with the granularity processing and production requirements of the customer, after the automatic dryer (or after drying) molding, and then the package waiting for sale.
