Calculating crushing constant using bonds law bond work index formula-equationee this useful summary table of bond work index by mineralsor any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the work index always means the equivalent amount of energy to reduce one ton of bond s law for crushing mills -.24th Apr, 2020. Mithun Nath. Vesuvius. Hi Tomaso Veneroso, Not sure other than Rittinger’s law for determining the crushing and grinding efficiency. Energy consumed is proportional to the new.
Bond S Law For Crushing Mills aquacristalfr. bond 3fs law for crushing mills Relationships between comminution J energy and product ball rod mills and has become likely a standard The general form of Bonds equation is as follows 6 where W is the work input (kWh t) Wi is the work index (kWh t) which expresses the resistance of the material to crushing and grinding and F80 and P80.Bond’s Law • The 80 passing size of the product may be calculated from the following Bond equation in. = 𝑶33 0.04 + 0.40 In which the characteristics of the material are taken into consideration by the work index factor Wi and O33, the open side setting of the crusher at the bottom of the crushing.
Chapter 3 - Particle Technology (Size Reduction) Kick’s law the work required for crushing a given mass of material is constant for the same reduction ratio, 3.2.2 Bond crushing law and work index.1. Rittinger’s Law n = 2 . K r is Rittinger’s Constant . 2. Kick’s Law n = 1 . K k is Kick’s Constant . 3. Bond Crushing Law n = 1.5 . W i is Work index in KWh ton and D in mm . Example 4 Calculate the Power required to crush 50 ton h of coke given the following data W i = 115.13 KWh ton Feed particle diameter = 50 mm Product.
Dec 17, 2015 Slide 1 CRUSHING LAWS Slide 2 Content Crushing laws Rittinger law Kicks law Bonds law Slide 3 Introduction In the materials processing industry, size reduction or comminution is usually carried out in order to Increase the surface area because, in most reactions involving solid particles, the rate of reactions is directly proportional to the area of contact with a second phase.6) Bond crushing law a. Calls for relatively less energy for the smaller product particles, than does the Rittinger law. b. is less realistic in estimating the power requirements of c. states that the work required to form particle of any size from very large feed is proportional to the square root of the volume to surface ratio of the product. d.
An impact pendulum that follows strictly Bond's standard for crushability measurement [1, 5] has been used (Figure 1), which allows calculating the crushing, or impact, work index.Mar 11, 2016 Rittinger’s theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter or, as I have fully expressed it “The work done in crushing is proportional to the surface exposed by the operation or, better expressed for this purpose, the work done on a given mass of rock is proportional to the reciprocal of the.

The power required is 89.5 kW.
Calculating crushing constant using bond s law. B ond f c crushing and grinding calculations. The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example the finer the grind size desired the higher is the kWh t required to grind to that size.Base on Bond’s Crushing Law, the power required to crush a certain material will change by ___ if the diameter of the product is made smaller by 50 a. 50 c. 41 b. 25 d. 75 . 39. In crushing a certain ore, the feed is such that 80 is less than 50.8 mm in size and the product size is such that 80 is less than 6.35 mm.
