The standard diameter size of the grinding media is 1.0 mm. however, it can be ordered to use 0.3 mm bead size. Since the Getzmann basket mill is attached to a High-Speed Disperser model, those with an adapter allow the user to switch between the basket mill system and a motor shaft for high-shear dispersing easily.
High quality 60mm 80mm 100mm forged grinding steel ball For Ball Mill media from China, China's leading grinding steel balls product, with strict quality control grinding media ball factories, producing high quality grinding media ball products.
Silicon Carbide Balls are very high-cost grinding media that are used for milling same materials (silicon carbide ball to mill silicon carbide materials) to avoid contamination. They are only available in 5mm,10mm, 15mm and 20mm sizes.
The Azzaroni equation indicates that the correct ball size for the 2.93 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 cross-section of the balls charged to the mill.
The grinding media Ball bounces seriously, causing part of the energy loss in the rebound, so the energy of grinding media ball is not more used for crushing, thus affecting the crushing; 2 When the ball and the ball contact with each other, sliding severe, cannot effectively engage in the ball between the mineral particles, so that the ...
Smaller sizes are more appropriate for attritors. For example, 5mm media are used in many attrition mill applications, whereas 10-15 mm may be a good start for a lab ball mill. For small-media mills, media sizes are typically smaller than 2 mm.
