Wear of vibration ball mill in wet grinding at constant temperature

Optimisation and analysis of bead milling process for preparation of highly viscous, binder-free dispersions of carbon black pigment

“…The other component of cost is associated to the wear and tear on the milling equipment. The wear of the conventional ceramic or metallic grinding media needs to be considered as this can lead to contamination of the dispersion (12)(13)(14)(15). The optimum milling process parameters, i.e., the milling time and the milling speed, to prepare pigment dispersion depends on a number of factors including the pigment hardness, the pigment aggregate size, the solubility of pigment in the dispersion medium, the effectiveness of the dispersant(s) and the design of the milling equipment (16)(17)(18)(19).…”

Effects of Operational Conditions on Fine Grindability and Wear of Grinding Beads in Limestone Bead Milling

“…The particles produced by grinding are mainly contaminated by wear of the grinding media and it is well known that this phenomenon is unavoidable for milling operation with grinding media in the micron or submicron region [9][10][11]. It is likely that such contamination might be also occur in the limestone bead milling of this study in the same way as when using traditional media mills such as tumbling or vibration mills [10,11]. The relations between the loss in mass of the grinding beads Mb and mass of product particles below 1 μ m W 1 for bead diameters 0.3 -0.8 mm are shown in Figure 9.…”

“…The bead mill was developed for fi ne or ultra-fi ne grinding in the submicron or nanometer region, where other conventional stirred media mills exhibit low grinding effi ciency [5][6][7][8]. While the grinding operation is accompanied by the wear of the grinding media [9][10][11], there are few examples of studies at bead mills operating at sub-millimeter grinding media size [12]. Our main research objective is to quantify the eff ect of the operating conditions of the bead mill [13][14][15][16][17][18][19][20] on the production of fi ne particles and the bead wear during the milling from the viewpoint of practicality.…”

Crack Initiation Mechanism on the Glass Beads Used as Grinding Media in an Agitation Bead Mill

“…Studies on the ball wear with tumbling ball mills have been carried out for many years (Suzuki, 1964(Suzuki, ,1971; Austin and Klimpel, 1985; Vermeulen, 1986; Concha, 1986,1987;Howat and Vermeulen, 1988). Wear of beads was studied with vibration ball mills with beads smaller than 3 mm and under high-energy input (Rose and Jimbo, 1963;Jimbo, 1964; Nishitake and Matsuda, 1967; Suzuki et al, 1989; Yokoyama et al, 1992). Similar study with regard to a centrifugal ball mill was also carried out (Yamauchi and Nishiyama, 1964).…”
