Crushing Circuit"E" covers the fundamental factors of a good crushing plant if floor space and expense are not critical. Crushing Plant Design and Layout Considerations SUMMARY
Compressive crushing is applied in crushing plants used in mineral, mining, and aggregate in-dustry for fragmentation of rock materials. From a global perspective, the total volume of crushed rock is massive and corresponds to several billion tons. All societies have to fulfil a daily need of rock material products and its derivatives such as metals and minerals. …
for these products, pulverized mineral processing plants have production rates that are less than 5% of the production capacities of conventional crushed stone plants. Two alternative processing systems for pulverized minerals are summarized in Figure 11-19.2-2. In dry processing systems, the mineral aggregate material from conventional crushing
