Calculate Ball Mill Grinding Capacity

The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent.

Optimization of mill performance by using

dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate. A variation in total ball angle can be detected and linked to grinding efficiency and charge expansion. This could help the operator to make the right decision and keep the mill running in such a way as to be close to the optimum pulp

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

What is the mining reward equation? - Monero Stack Exchange

For mining profit, the simplest would be the following: Daily mining estimate = ( (your hashrate) * (current block reward) * 720 ) / (network hashrate) Note that you can't use Bitcoin hashrate for this, as it is a different alghorithm (CryptoNight). For example, a RX 470 will yield about 600H/s for Monero.
