Get QuoteBall Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications.
Get QuoteThis project is to design and fabricate the mini ball mill that can grind the solid state of various type of materials into nano-powder. The cylindrical jar is used as a mill that would rotate the material that about to be ground, a motor is used to power the system so that the jar can rotate in high speed and using the regulator controls the speed of the rotation of the jar.
Get QuoteVibratory and planetary ball-mills (widely used as high energy mills) available commercially are generally not designed for the specific task of synthesizing nanophase materials in large quantities.In the present work, we present the criteria adopted in the design of a high energy, high capacity mill and comparative results obtained for the mechanosynthesis of iron carbides.

Get QuoteThe grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the specific impact energy of the balls calculated from Discrete Element Method simulation. This relationship was successfully used for the scale-up of a rocking ball mill, and the optimum design and operating conditions for the rocking ball mill could be estimated by the specific impact energy
Get Quote08-02-2017· The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed
Get Quote01-01-2016· Thus, the medium could be steel or cast iron balls when the mill is designated as a ball mill, or it could be steel rods where the mill is known as a rod mill. When no grinding medium is charged it is known as an autogenous mill. In this chapter, we initially discuss the design and operation of tubular mills followed by ball mills.
Get QuoteThe vertical ball mill is used for the processing of high-viscous pre-mixed pastes, like chocolate, compound, crèmes, nut- and seed-paste. The continuous design vertical ball mill can be used in a 1 3 stage refining system, with 1 3 ball mills in a sequential row after the pre-mixer.
Get Quote10-08-2020· Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.
