Mill Speed Control Using Programmable Logic Controllers

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 ...

the control loop will attempt to add water to Cyclone 1 sump to achieve a particle size of 15%+ 300 µm. If the hardness of the ore increases, the particle size in the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio, and hence

to mill operating conditions. The sensor output was envisioned to eventually form part of the mill control philosophy. Samples were taken of the mill feed and discharge streams at the different operating conditions and analysed for grind as well as PGM and Cr 2 O 3 content. The majority of the PGM's in the UG2 ore are in the silicates and ...

Modelling and Control of Ball Mill Grinding

Modelling and Control of Ball Mill Grinding. Dynamic experiments were performed in a continuous open-circuit 40×40 cm ball mill using a pseudo-random binary sequence of the feed rate and measuring the variations of the discharge particle-size distribution. The impulse response is calculated by a cross- correlation technique.

Grinding Mill Control - Grinding & Classification Circuits ...

The Control philosophy controlled to a mill load set-point by automatically adjusting the ore feed rate, and the acoustic control controlled the mill speed. This is all a commissioning exercise and one of the things we wanted to do was - incorporate an additional loop whereby mill speed is automatically adjusted to control mill weight/load.

Grinding Circuit Control Strategy - 911 Metallurgist

The ball mill load control system: The main control scheme is the ball mill load controller. Any additional capacity of the ball mill depending on the grind settings is sensed by the ball mill load controller and the feed rate is increased (if desired to bring the ball mill its capacity). It was implemented as a cascade controller to set the ...
