Calculation of energy required for grinding in a ball mill Int J Miner Process 25 4146 The Bond work index Wi as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product
•To grind the given limestone material to a smaller size using a ball mill and to obtain the size distribution of the initial and the final mixture by sieving •To estimate the energy required for the grinding operation •To analyze the results using the available theories
First a Jar Mill grindability test requires a 5 lb 2 kg sample and produces a direct measured specific energy net Hphrt to grind from the design feed size to the required product size The second test a Bond Work Index determination results in a specific energy value net Hphrt from an empirical formula
mill is the energy consumption The power supplied to the mill is used primarily to lift the load medium and charge Additional power is required to keep the mill rotating 813 Power drawn by ball semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure 83 Ad this can be used to establish the essential features
Ball mills work well on hard brittle materials They are not as suitable for grinding elastic ductile or fibrous materials or for fine grinding in general Ball mills can blend and grind at the same time yielding a fine intimate mixture Conventional ball mills are usually limited to
Calculation of energy required for grinding in a ball mill Int J Miner Process 25 4146 The Bond work index Wi as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product
The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input The innovative design of both the mills and the grinding jars allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming effects These ball mills are also suitable for mechano chemistry
between the ballmill power draw values determined from the Denver slide rule and those calculated from the proposed model zFrom the distribution of the points around the line of comparison the good agreement of the results received is obvious 0 200 400 600 Ball mill power draw predicted from the Denver slide rule kW 0 200 400 600
Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content
to predict the specific energy consumption required by the ore fed to these circuits The vertical mill demonstrated the same ability to achieve the product specifications of the ball mills while proved to be able to reduce the medium specific energy consumption in about 40
