detailed overview and knowledge of the characteristics of a raw
material is of utmost importance, especially when planning the layout of
a crushing plant. In order to minimize all possible risks extensive
trials are necessary to obtain information on the properties of the raw
materials . A clear definition of the required crushing capacities and
the desired product quality can be precisely determined by using the
Bond Index test methods. Using the Bond Index test procedures it is
possible to calculate crushing / abrasion behavior of mineral samples.
This knowledge is essential to define the required ball mill layout and
production capacity.
In order to perform the Bond Index Test successfully it is necessary to use pre-crushed sample material as defined below:
Module Ball Mill
Minerals pre-crushed to < 3.35 mm and sieved
Drillcore pre-crushed to < 3.35 mm and sieved
Half Drillcore pre-crushed to < 3.35 mm and sieved
The Bond Index conforming ball charge consists of:
43 x 1.45” balls
67 x 1.17” balls
10 x 1” balls
71 x 0.75” balls
94 x 0.61” balls
The optimum number of grinding balls is 285. However, the ball diameters
vary due to wear. Therefore, the total ball number should be adjusted
from time to time to ensure a total mass of 20.125 grams.
The grinding jar of the Bond Index Ball Mill measures 12″ x 12″ and has well-rounded corners.
Module Rod Mill
Minerals pre-crushed to < 12.50 mm and sieved
Drillcore pre-crushed to < 12.50 mm and sieved
Half a drillcore pre-crushed to < 12.50 mm and sieved
The Bond Index conforming rod charge consists of:
6 rods of 1.25“ diameter and 21“ length
2 rods of 1.75“ diameter and 21“ length
The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design.
At
least 15 to 20 kg sample material is required to simulate a closed
grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI)
is used for particle size determination in a size range from 25 mm down
to 2.1 mm whereas Ball Mill Work Index (BWI) is used for the range from
2.1 mm down to 100 μm.
Adjustment of grinding parameters:
The
operation display permits convenient selection and storage of
parameters such as rotation counter, rotation speed, grinding time,
start and stop.

Please note:
受樣品材料性質和儀器配置/設定的影響
球和棒磨機主要有相同的概念包括一個12 x12“帶球的罐或12 x24 ”罐和研磨棒。
研磨罐放到一個電機驅動旋轉的支架，有三種擺放方式：:向上加載，水平研磨，向下排出。
進行邦德功指數測試需要用到已知的研磨球或研磨棒，電子控制集成的驅動器配有過載保護和許可和控制不同的速度。
在磨削過程中球/棒運動和研磨罐的速度差產生相互作用和影響的摩擦力,釋放出所需的粉碎能量。這些力量之間的相互作用產生有力的粉碎效果。
根據技術改造和誤差調整
