The production process of chromite flour
1. Raw material preparation
washing raw material of chromite sand
2. Drying and screening
After washing, the raw materials need to be dried ， after Drying ，then screening
3. Magnetic separation
removing iron and silicon. The chromium content after magnetic separation should reach more than 46%, and the silicon content should be less than 1%.
4. Packaging
25kgs pvc bag+1ton big bag
5. Agglomeration treatment
In order to improve the performance of chrome ore powder, it is usually necessary to agglomerate it. This can be achieved through the cold pressing pelletizing process, that is, the chrome ore powder is mixed with a binder and sent to a mixer. After mixing, it is transported to a pelletizing machine for pelletizing, and the chrome ore powder balls are obtained after drying.
6. Use of binders
During the agglomeration process, the use of specific binders can improve the strength and stability of the pellets. For example, the binder formula of a chrome ore powder ball includes silane-modified polyimide/bentonite composite material, silane-modified epoxy resin and other ingredients.
