(1957) and Hukki (1962, 1975) that Kicks's is the most applicable for crushing, Bond's for ball mill grinding and von Rittinger's for fine grinding is generally accepted. Of these theories, that of von Rittinger has a theoretical basis founded on the new particle surface area gen
Determination of the nip zone angle in highpressure grinding rolls 249 four pistons, and through decreasing the volume of the space between the rolls as the feed material is dragged deeper into the crushing zone. The maximum pressure is expected to occur in the area, where the volume decreases are minimal. In order to find
Answer: Tables 939 FC A bond will mature in 20 years and has a maturity value of 1,000. It has an eight percent coupon interest rate and pays interest annually at year's end. Currently it is selling for 1,150. Determine its yield to maturity. Answer: FC % A bond will mature in 20 years and has a maturity value of 1,000.

The test results confirmed the beneficial effect of circulating load, and also that the throughput benefits of higher circulating load are limited due to classification efficiency. The effect of classification efficiency and circulating load was also investigated by Morrell (2008) who used Bond ball mill tests as the base line (Bond, 1962).

IE2 On 1 January 20X1 an entity issues a 10year bond with a par value of CU150,0001 and an annual fixed coupon rate of 8 per cent, which is consistent with market rates for bonds with similar characteristics. IE3 The entity uses LIBOR as its observable (benchmark) interest rate. At the date of inception of the bond, LIBOR is 5 per cent.

Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be 'set' in that it is no longer fluid, but it may ...
