Step #1 Crushing: The feeding size is less than 150 mm. The tungsten rock is crushed by a jaw crusher and cone crusher. A vibrating screen can screen the materials and remove the fine powder. The discharging size is between 35 mm. Step #2 Grinding: As it is easy to form slime, a rod mill is used to grind the ore, avoiding overgrinding.
