Bitcoin Mining Difficulty What is it And How Does it

Before we even begin to understand what bitcoin mining difficulty means, we need to know how mining works. We have covered this topic in detail before, so we will just give you a little overview before getting into the different nuances of difficulty. Following that, we will look at how mining difficulty is calculated and how it changes to suit the network’s needs.

Usually the charge volume of SAG mills occupy between 30-40% of its internal volume at which the grinding rate is maximized. When the charge volume is more, then the throughput suffers. The fill level is monitored by mill weight measurement as most modem mills are invariably mounted on load-cells.

How Temperature Affect Grinding Efficiency

The effects of temperature on autogenous grinding can be immediately divided into rheological effects and mechanical effects. The rheological effects are a result of the substantial increase in the viscosity of water as the freezing point is approached. The change in apparent slurry viscosity which results from changing temperature is shown in Figure 1. As can be seen, the effect at high

How to Calculate Grinding Mill Operating Efficiency

In grinding, operating Efficiency compares the operating work index of a comminution machine to the Bond work index from bench scale crushing and grindability tests or/and pilot plant tests. Economic Efficiency is comparing the income from production to the planned income from production. Energy as consumed in comminution machines and the required energy as determined, from bench scale
