Formula to Calculate Bond Price. The formula for bond pricing is basically the calculation of the present value of the probable future cash flows which comprises of the coupon payments and the par value which is the redemption amount on maturity. The rate of interest which is used to discount the future cash flows is known as the yield to maturity (YTM.)
Application of the Bond work index should provide an enhancement of the previous approaches based on rock and explosive properties.The Bond work index was determined by use of the Bond mill for several different minerals and rocks at the sites being blasted and the results were compared with published values.
The second procedure is based on a standard Bond work index test but, rather than running the test to stability, the test is terminated after only three cycles. The grindability (gbp) of the last cycle, in conjunction with the feed and product particle size distributions, is used to calculate the work index according to Equation 2.
