Electronic ear in SAG mill Automation & Control
Aug 25, 2004· Another strategy to control the mineral feed is to control the electric current or power of the elevator. The current is a meassure of mineral mass milled. If you control the current with the mill feed you'll reach a stability of the mill. The electronic ear is a good measure for alarm but not for control. I hope i can help you David FernandezBall Mill Feed Control Using Electric Ear,Ball Mill Feed Control Using Electric Ear. For example, a hardened P20 or H13 steel mold that is finish-milled using a 6-millimeter ball mill at a feed rate of 6 meters per minute with a 0.1-millimeter pitch distance and then peened for polishing using a 6-millimeter striker at a feed rate of 6 meters per minute and the same 0.1-millimeter pitch distance will produce a perfectly smooth.

Ball Mills an overview ScienceDirect Topics
where d b.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.Ball Mill an overview ScienceDirect Topics,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 particle-size measurement device and size-control cyclones.
