The grinding media are iron and steel balls for a ball mill with a diameter of 15150 mm carbide balls with a diameter of 820 mm iron or steel cylinders (such as "cylpebs") round steel rods with a diameter of up to 130 mm and a length corresponding to the length of the mill drum and silicon or ore pebbles up to 200 mm in size large pieces
The size of the ball mainly depends on the particle size of the material to be ground and the diameter and speed of the mill can be considered appropriately. Formula (115) is an empirical formula for spherical diameter and feed size. dmax — The maximum diameter of steel ball mm amax — the maximum size of feeding granularity mm.

The relatively large ball sizes employed 3″ 4″ (75 100 mm) contribute a significant impact component to the overall wear. The number of impacts in primary ball mills are far more frequent but have less magnitude than those experienced in SAG mills.
With this in mind it is interesting to make a qualitative comparison of the ball size distributions which should be generated by 76 mm pearlitic carbon steel balls versus 76 mm martensitic alloy steel balls in the m mills. The 76 mm pearlitic carbon steel balls used have a relatively flat hardness gradient from surface to center.
During the runningin process the amount of steel balls is added for the first time which accounts for 80 of the maximum ball load of the ball mill. Steel ball sizes are Φ120㎜ Φ100㎜ Φ80㎜ Φ60㎜ Φ40㎜. For example the 100150 tons ball mill has a maximum ball loading capacity of tons. For the first time 30 40 of

The Azzaroni equation indicates that the correct ball size for the m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the crosssection of the balls charged to the mill.
Ball End Mills. 3 704 products. Ball end mills have a rounded nose and create a roundbottomed groove in milling tasks. Also known as ballnose end mills they are rotated against a workpiece to make roundbottomed slots and pockets or mill complex shapes without sharp corners.

Following this rule of thumb the number of grinding balls for each ball size and jar volume is indicated in the table below. To pulverize for example 200 ml of a sample consisting of 7 mm particles a 500 ml jar and grinding balls sized at least 20 mm or larger are recommended. According to the table 25 grinding balls are required.
