    2021-6-8 · Open-pit mining depends mainly on the size of the mine and the volume of the loading shovel typically 500 to 1300 mm. When mining underground it depends mainly on the size of the mine and the mining method generally 300 600 mm. The size of the broken final product varies depending on the purpose of the crush.
