The grinding surface will also increase. All these will increase grinding efficiency. 4. Based on main mill structure and parameters, strengthen some critical components (such as foundation, central axis rack, relieving tool, star rack, gearbox, etc), reinforce cement foundation, improve stability of damping device, blower box, shell.
The larger feeding particle size is, the greater the work done by the ball mill on the ore, which impacts the grinding efficiency. To reach the eligible grinding fineness, the workload must increase. The energy consumption is also increasing. If the feeding particle size reduces, the crushing product particle size is small.
Control Feed Size. The particle size of the material entering the ball mill is controlled between 25-15 mm (the diameter of the ball mill is different for different feed sizes). Excessive rules will cause the ball mill to have too much fine material during the grinding process and cannot achieve the friction between the material and the material.
Table 3 is a summary of the preliminary tests (in duplicate) using various proportions of balls and pebbles. The on-line torque measurement was used for early measurement of the power drawn by the mill, so that the grinding time could be calculated, to maintain the same amount of energy for all tests (i.e. assuming a constant grinding efficiency).
Optimize the grinding process according to the ore properties of the original ore, such as pre-throwing, pre-concentration, stage grinding, and pre-classification, which can reduce the amount of grinding, recover useful minerals in time, and improve the grinding efficiency of the ball mill.
Ten Ways to Improve the Grinding Efficiency of Your Ball Mill There are a lot of problems that most mineral processing plant will meet when operating the ball mill, such as low grinding efficiency, low processing capacity, high energy consumption, unstable …
Ten Ways to Improve the Grinding Efficiency of Your Ball Mill. Add some chemical reagent to change the grinding effect and promote the grinding efficiency during the grinding stage; Ⅱ.Change the grindability of the raw ore, such as heating the minerals, change the mechanical properties of the ore, reduce the hardness of the ore.

Cement mill - Wikipedia. Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.
