CALCULATING PLANT PRODUCTION
Once you have properly calibrated your plant, production will be maximized. Not much else can be done to
improve the hourly output. For planning and estimation purposes, the remaining six steps of the production
determination procedure must be accomplished to get an idea of what the production will be. This information is
essential for your responsibilities as planner and manager.
JAW CRUSHER PRODUCTION RATE
The jaw crusher capacity depends upon the size of the jaw crusher, the type of rock being processed, and the

setting at 2 1/4 inches. Table 5 can be used to determine the capacity of the jaw crusher.
TABLE 5. JAW CRUSHER CAPACITY (tons per hour)
Table 5 relates the unadjusted jaw crusher capacity in tons per hour to the crusher size and the jaw (or product)
setting. Since there is no 2 1/4 inch reference in the table, interpolate the capacity as follows:
