Mechanical Milling: a Top Down Approach for the Synthesis ...
· In that work we employed a twostep process; 1) ball milling of silicon, and 2) spray pyrolysis of ball milled silicon in hexane at 1000± 1100℃ in an argon atmosphere. Silicon powder ( %, particle size ) was ballmilled in an attritor ballmill at 400 rpm for 30 h in hexane. It was found that slurry of ballmilled silicon in hexane was produced as a result of the milling. This ...Get Price
Explain Construction And Working Of Ball Mill.
· Working of Ball Mill: The drug to be ground is put into the cylinder of the mill and is rotated. The speed of the rotation is very different. At low speed, the mass of balls will slide or roll over each other and only a negligible amount of size reduction will occur. At a high speed, the balls will be thrown out to the walls by centrifugal force and no grinding will occur. But at about 2/3rd ...Get Price
Process engineering with planetary ball mills
Planetary ball mills are well known and used for particle size reduction on laboratory and pilot scales for decades while during the last few years the appliion of planetary ball mills has extended to mechanochemical approaches. Processes inside planetary ball mills are complex and strongly depend on the processed material and synthesis and, thus, the optimum milling conditions have to be ...Get Price

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
