A comparison of the properties of the oxide formed by the Bartonpot and ball-mill processes is given in Table 1. Economic Considerations The operating cost of a Barton-pot system amounts to 0.5 H per day maintenance. This figure varies with the skill of the operators and the maintenance programme in force. Horsepower per tonne of oxide …
One of the advantages of a rod mill is that it can handle a higher capacity than a ball mill of the same size. Additionally, the grinding medium in a rod mill is more uniform than that in a ball mill, and this can be beneficial for certain materials. Rod mills are also relatively low-maintenance, making them a cost-effective option for many ...
A. The cost of a Wet Ball Mills can vary widely depending on its size, capabilities, and complexity. Most of the price of Wet Ball Mills ranges from US $ 5000 to $ 5000000 per Piece.
