Ball mill grinding of phosphate rock to prepare the phosphate rock for use in the . The practice of using acidic process water for make-up water for wet grinding. Chat. The effect of grinding on the acidulation of phosphate rock.
A Bond ball mill work index is then performed on the mill product for the design of SAG-ball mill circuits. This is important because it was found that there was a 1–1.5 kWh/t higher ball mill work index if the –3.35 mm ball mill test feed size is obtained by SAG mill grinding compared with crushing.
First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) 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 Hp-hr/t) from an empirical formula.

Mixer Mill MM 500 control. The MM 500 control is a high energy laboratory ball mill that can be used for dry, wet and cryogenic grinding with a frequency of up to 30 Hz. It is the first mixer mill in the market that allows to monitor and control the temperature of a grinding process. The temperature area covers a range from – 100 to 100 °C.
The Ballbar test will measure any deviation the machine makes from a perfect circle, recording data as the two axes work together. Errors such as backlash, level/squareness, servo mismatch, reversal spikes, vibration, stick slip and other problems can be determined. Users can be useful in determining what feedrate delivers the best accuracy by ...
Bond Ball Mill Work muenchen-fit.de. Bond Ball Mill Work. the bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the bond work index.The test is a 'locked-cycle' test where ground product is removed from test cycles and replaced by fresh feed.
Ball Mills use grinding media in spherical or cylindrical shapes in rotating containers to grind a wide range of material types to very fine sizes. Jars and grinding media are available in a wide variety of material types to optimize performance characteristics for long-term wear-resistance, low contamination levels, or economical operation.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
