WhatsApp: +86 18203695377The first fillingin calculation follows these steps: The sand return ratio of the classifier is measured, and the new feed ore and the sand return are screened out to calculate the particle size composition of the whole feed ore of the ball mill. From the grain size composition of the total ore, the grain size that does not need to be ground ...
WhatsApp: +86 18203695377Mechanical milling is a promising route for production of submicron and nano sized silicon powders, but it is challenging to predict and control the product properties. In this study a metallurgical grade silicon quality was milled in a planetary ball mill and the properties of the powder were investigated as a function of grinding time, grinding bead size (20 mm, 2 mm, mm) and rotational ...

WhatsApp: +86 18203695377Each grinding balls are round balls with precise dimensions. The sizes of Fote grinding steel balls can be designed according to customer requirements. Generally, the ball diameter is between 20mm and 125mm. You can also design 10mm, 11mm or other diameters of steel balls. Small steel balls: 40mm or 60mm.
WhatsApp: +86 18203695377The method of ball distribution for a ball mill can be summarized as follows: 1. Take all the ore samples from a ball mill (usually take new ore and returned sand samples, then match the samples in proportion) for sieving analysis. Divide them into several particle sizes, such as 1812, 1210, 108, 86, etc. Then weigh each particle size, and ...
WhatsApp: +86 18203695377A ball mill with fewer than 35 percent balls can effectively allow the steel ball to fall freely and create a more significant impact force. There are several types of steel balls for ball mills, and their diameters are usually about 20mm * 120mm, while the diameter of the steel balls for super large ball mills can be 130mm * 150mm.

WhatsApp: +86 18203695377Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
