I'll also share the best mining route, allowing you to farm ores in a way that can allow you to level up mining efficiently and also give you a way to obtain a large number of resources to sell or use when leveling up other skills.
ادامه مطلبA 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 or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

ادامه مطلبCrushers, grinding mills and pulverizers are types of grinding equipment used to transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. Grinding equipment can be classified into to two basic types, crushers and grinders.
ادامه مطلبBall mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.
ادامه مطلبI heard mining makes later more money than farming so grinding for it wont be stupid even if the profit difference is 1.2m it should be worth it For skill treas watch some yt vids they will help u better than the forum could
ادامه مطلبIn a narrow sense "grinding" is used (also referred to as friction grinding in mining). "Grinding" refers to pulverization in the area of finer particle size (crushing of fine particles) and may be distinguished from crushing. Besides these, "milling", etc. are also used. Thinky Corporation uses "pulverization".
ادامه مطلبThese differences in the grinding process also change the properties of grinding products, which in turn can affect the efficiency of downstream separation processes such as froth flotation.
