the processes of crushing, grinding, milling, micronising, etc. Changing .. The resulting equations are due to: Rittinger, Bond and Kick, . crushing law equations.
methods: 1. Compression or crushing – disintegation by two rigid forces . Empirical Equations to estimate energy : Bond (1952) . Bond's law : Intermediate.
The minimum energy required for crushing is the energy required for creating fresh surface. . Note that the definition of particle size in Bonds law is different: 80.
Many of them do not take care of mechanical losses in the crusher, they only consider the . Bond, so we are having three laws of comminution and we call it Kicks law, ... So when we deal with very large size of feed we can write the equation.
mental data well, and therefore a modified Bond equation was developed. . is applicable for crushing, Rittinger's equation may be used for finer grinding, and . Law can be reasonably applied to the range in which ball/rod mills operate in.
Sep 4, 2016 . Three laws of comminution or size reduction such as Kick's law, Rittinger's law and Bond's law are defined and its objectives in industrial . Finally differential equation is described which gives expressions of all three laws. . Lesson 10 Crushing and Grinding: Technical Level Intermediate - Duration: 37:09.
There is an equation for size reduction. . You can calculate power required by the bonds law of crushing. For more about the bonds law, see the link below.
Oct 25, 2016 . However,equations Rittinger's law and Bond's law were developed from . ROLLER MILL Roller mills are similar to roller crushers, but they.
fc is called the crushing strength of the material which , on integration gives: = Kick's Law(1) . mass) is proportional to 1/L, equation (2) postulates that the . smaller particles, than that predicted by Kick's Law. . Assume Bond's equation.
Fred Chester Bond (June 10, 1899 – January 23, 1977) was an American mining engineer. . called the 'Bond Work Index', which relates power consumption in crushing and grinding to the . This term and the terminology of "laws of comminution", as in "Rittinger's law", "Kick's law", and "Bond's law", are sometimes used.
crusher were compared with those of the Bond crushing energies (estimated from the Bond . Each calculation step includes the solution of equations of motion to a particle, using a force-displacement law for each contact1. The rock is.
2) the efficiency decreases from crushing to grinding steadily; the upper . case of general equation (1) derived by Walker,. Lewis. McAdams" and . Rittinger's theory E = C ( 1 /x2 —1 /x1 ). Kick's law. E. — / n (x2 / x1 ) . . . Bond. E — 2 C (1/NT2.
Comminution laws estimate energy Esigma for crushing / grinding by following formulas: Bond law: Esigma = Wb * 10 * (1/SQR(L2)-1/SQR(L1)), kWh/t;; Rittinger.
units such as crushers and grinding mills, is ore's work index. The work . grindability, and is used in Bond formula to calculate the required energy. Bond has.
The calculated power is a key aspect in the design of disc crusher machines. . It is also important to mention the theory called Bond Law, which states that the . describing a process of disintegration is "The Population Balance Equation",.
It starts with Bond's Work Index equation: w1 . For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the.
May 1, 2018 . pressure and displacement based on the law of motion of material is examined. Energy . such as Bond's model and Rittinger's model [2,3]. .. Finally, the crushing pressure can be obtained by Equations (2), (8) and (9).
useful "laws" are available, but a` single generally acceptable ... For coarse crushing Kick's law has been favored: . Equation, -1 for kick's, and -3/2 for Bond's.
reduction is given by Bond's law as follows (in kWh/short-ton) [29, 30]:. W = 10Wi . For jaw crusher application, the specific energy term in equation (3) can be.
