All three theories can be applied for a certain range of particle size: Kick's Law for coarse size particles (for crushing), Bond's Law for medium size particles, and …

given as Equation 1, and is often referred to as "Bond's equation" or "Bond's law." E=10×Wi(1 √P80 − 1 √F80) ( 1 ) Where: 1. E is the specific energy consumption in kWh/t 2. Wi is the work index (see discussion below for the units of this quantity) 3. P80 is the 80% passing size of the product of the comminution process in µm 4.

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock ( geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear …

The general form of Bond's 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; …

The Bond work index (Bond, 1960) is based on Bond's law, which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of …

The Bond work index ( Bond, 1960) is based on Bond's law, which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of Rittinger's law. Accordingly, the energy consumed in reducing the particle size from x F to x p (both measured as 80% undersize) is given by.

funnel-shaped casing, open at the top, the crushing head is mounted on a heavy shaft in the form of a truncated cone, gyrates inside a casing. The upper end of the shaft is held in a flexible bearing and the lower end of the shaft is driven by an eccentric so as to trace a circle. The crushing action takes place around the whole of the cone.

It is not possible to estimate accurately the power requirement of crushing and grinding equipments achieve the size reduction of a given material. Thus, for the same a number of empirical laws have been put fonvard, such as Rittinger's law, Kick's law and Bond's law. • 2.3.1 Rittingers Law Mathematically, the law can be written as where

Bond's law | Article about Bond's law by The Free Dictionary. Bond's law. [ ′bänz ′lȯ] (mechanical engineering) A statement that relates the work required for the crushing of solid materials (for example, rocks and ore) to the product size and surface area and the lengths of cracks formed. Also known as Bond's third theory.

AS a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing plant.

Equation (11.2) is a statement of Kick's Law. It implies that the specific energy required to crush a material, for example from 10cm down to 5cm, is the same as the energy required to crush the same material from 5mm to 2.5 mm. Rittinger, on the other hand, assumed that the energy required for size reduction is directly

Hence W = constant x P. That is to say, the work done, in crushing a given weight of ore from any one stage to the next, would, from this reasoning, be proportional to the number of particles at the first of these two stages. If this were actually the case, the law deduced would give, with the finer sizes, extremely large work values, even ...
