You can often save money by selecting the maximum allowable aggregate size. Using larger coarse aggregate typically lowers the cost of a concrete mix by reducing cement requirements, the most costly ingredient. Less cement (within reasonable limits for durability) will mean less water if the water-cement (w/c) ratio is kept constant.

Usually, the initial comparison which is made between a 7 Ft. crusher and a 10 Ft. crusher is that of price versus capacity. Theoretically, the capacity of a 10 Ft. crusher is 2¼ times that of a 7 Ft. while the selling price is approximately 3 times that of the 7 Ft. On that basis alone, it would appear that the 10 Ft. could not be justified.
