Barmac Crusher Efficiency. However, the product size distribution contains a high proportion of fines. It is argued that the production of these fines accounts for the high energy consumption, and Bond's method is modified to account for this, by considering the crusher to be, effectively, a number of smaller crushers in parallel, each having a different reduction ratio.

Olives are crushed with stones and pressing machines are used for oil extraction in the traditional method. Otherwise, a hammer crusher and a centrifuge system are used in modern olive trituration processes. The semi-traditional system is based on a combination of traditional and modern methods and machines.
Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, the global annual …
