The product particle size of overflow type ball mill is generally less than 0.2mm, which is suitable for fine grinding operations. 3. Efficiency of grinding mill. When choosing the grinding mill, we not only need to consider the price of grinding equipment, but also take the efficiency of grinding equipment into consideration.

Feed Mill Efficiency. roller mills are more energy efficient than hammer mills when grinding friable materials; the advantage for corn is <5% at sizes smaller than 500 microns, becomes 25-30% at 800 microns, and increases to perhaps >80% at a size of 3000 microns (cpm, 1992). the hammer mill (figure 4) remains the industry standard for size ...

The grinding effect is caused by the collision between the steel balls themselves and the collision friction between the steel balls and the material. The specifications, materials and usage of the steel balls will directly affect the work efficiency of the ball mill and even the entire production line of the concentrator, so it is valued by ...

Ideal for grinding finer products, stirred mills are known for their energy efficiency and compact design, reducing floor space requirements. These mills are based on gravity-induced and fluidized technologies, allowing for the optimum equipment solution for all comminution circuits covering secondary, tertiary, fine, ultrafine, regrind, and lime slaking applications.

High classifying efficiency means that those qualified grains can be discharged timely and efficiently,while low classifying efficiency means that most qualified grains are not discharged and sent to the ball mill for re-grinding, which is easy to cause over-grinding and thus affecting the separating effect.

If the temperature in the mill is too high, the ball will stick, which will reduce the grinding efficiency of the mill and affect the output of the mill. At the same time, the thermal expansion of the rolling mill barrel affects the long-term safe operation of the rolling mill.

Ball mill grinding efficiency is influenced by many factors: ore grindability, feed size, grinding product size, ball mill diameter and length, ball mill working speed, liner type, steel ball loading system, grinding concentration, return sand ratio in closed-circuit grinding and feed rate.
