Capacity of crushing system Plant Type When taking 20 mm - 0 When taking 40 mm - 0 １． １００ – １２０t/h １５０t/h ２． １５０ – １８０t/h ２００t/h ３． ２００ – ２５０t/h ３００t/h Both 5 – 2.5 mm and 2.5 mm – 0 are relatively prone to be excess. In general, about 20% of these fines are sold in one way or another, but the remainder are disposed of as unmarketable surplus most of the time. Therefore, the excess of fines generation (of 5 mm – 0 products) can be illustrated below in existing plants of the various sizes. Plant Type Generation of 5 mm - 0 Amount of surplus generated １． ５０ – ４０t/h About ４０t/h ２． ７５ – ６５t/h About ６０t/h ３． １１０ – ８０t/h About １００t/h The capacity of a BM7 sand-making system is determined by the generation of 5 mm - 0 products by the existing system.
