The P 80 of a ball mill work index test can be estimated if the P 100 is know based on this equation: Estimate grams per revolution when only P100 is known. NI43-101 reports often provide P 100 and the work …
Two are Polysius installations from Line 1, each with a capacity of 62t/hr. With Line 2 came cement mill 3, which has a capacity of 70t/hr. It is from IHI. Since we had high demand, in 2006 L&T India installed cement mill 4, which has a capacity of 150t/hr. At the moment we actually run some of the mills slightly above their rated capacities.
The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. Determining the Bond work index value is quite complicated, timeconsuming and requires trained operating personnel and …

The test determines the Bond Impact Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size.P80 = 25400 x …
Experiments were carried out in a closed wet-grinding circuit as shown in Fig. 3, using the 44-cm diameter Tower mill KM-5, charged with steel balls of 20-mm diameter weighing in a total of 350 kg.This mill was filled with 64 kg of limestone ore sizing −5+0 mm, and the rotation of the screw was settled at 85 rpm.
