As the name implies, crushing is the process of reducing large materials into smaller pieces. In mining and construction industries, crushing is an essential step that ensures the extraction and processing of valuable minerals and materials. Primary and secondary crushing are the two most common types of crushing operations.

This section looks at methods to get very large rocks crushed and ground until it is as fine as powder. The first concept that needs to come across here is that minerals are inside rocks and by crushing rocks, the minerals are exposed at the surface of the rock fragment. Only then can chemicals be used to extract the mineral.

Based on the JK Drop Weight test and principle of selective crushing, a multicomponent complex ore with its component minerals, i.e., pyrrhotite, sphalerite, and quartz, was used to explore the impact crushing characteristics and relationship between the complex ore and its component minerals. Results show that the order of impact …

Introduction. The high energy consumption of crushing is one of the main motivations to study the comminution of minerals. Tromans [1] listed several examples of energy consumption per country, showing that the energy spent in comminution constituted 1–16.7% of the total energy consumed by the industry.

Crushing and grinding is the most costly step in mineral processing because the power needed to liberate the minerals is very high. In this sense, grinding is commonly said to be the key to good mineral treatment and the major consumer of energy, accounting for up to 50% of a concentrator's energy consumption ( Table 6.3 ).

Changing the crushing circuit. Originally, the crushing circuit consisted of 20 roller crushers (14 in.×24 in.) arranged in five parallel crushing and grinding subsections. Each section had a separate fresh feed silo as seen in Fig. 2. The fresh feed was mixed with the crusher discharge and transported to a silo feeding 20 Locker Rotex screens.
