Sizing is also a very important part of ferro silicon manufacturing process. Standard lumps are easy to use as deoxidizing agent for steel factory. It’s crashed and then selected to 10-50mm, 50-100mm. Grains are easy to be used as ferrosilicon inoculant. Gain size usually are 1-3mm, 3-8mm, etc. Ferrosilicon powder can be used as flotation agent for various kinds of minerals. And atomized fesi powder are used as electrowelding materials. After those method, the ferro silicon manufacturing process will be complete and ready to be packed and delivered to users.
