speed, mill speed control. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back. Therefore, this application conceived a PID controller for control the mill speed, using Programmable Logic Controllers. Key-Words: - ball mill, critical speed, operating speed, speed control ...
This system allows plant personnel to control the vacuum required for effective stacker cyclone operations by means of an adjustable control valve. This system allows effective stacker cyclone operation as air enters the VABA piping, and is then passed through a swing check valve allowing air to enter the system.

The control system of claim 1, with said ball mill grinding circuit being operative in a reversed arrangement such that the new ore material passes to said production cyclone before passing to the ball mill grinding device and said actual load material solids flow is the underflow from said production cyclone.
The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed ...
mill achieved with MillStar’s Segregated Ore Feed Controller combined with the Power Optimiser: • The standard deviation of the mill feed control is greatly reduced. • The cyclone feed is more stable, allowing for consistent size separation and feed to downstream processes. Due to the tighter control the feed setpoint can now be set closer
The traditional instrumentation in each ball mill/hydrocyclone cluster system is installed on the common system components. Typically these measurements include hydrocyclone feed flow, feed density, manifold pressure, sump level, etc. Determining the exact source of the oversize can be a complicated and time consuming process for a busy

The ball mill has higher circulation load, it generates only 30 -35% of actual fines you require to be called as product. If your product size needed is 100% passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. The rest is oversize which has to be ground again.
