  • Alsto Bond Index Ball Mill – Mineral Stats

    Safety is a prime consideration for all Alsto equipment and the Bond Index Ball Mill is supplied equipped with acoustic enclosure. The ball mill is designed to accept a ball charge in accordance with F. C Bond’s standard. This ball charge consists of 286 balls as follows 44 x 35mm balls 67 x 30mm balls 10 x 25.4mm balls, 71 x 19.05mm balls and.The characterized PA flow is then construed as the feeder speed demand. The ball and tube mill control system, on the other hand, uses feeder speed control for maintaining mill level control only and so the fuel flow control is achieved through control of the feeder wise PA flow to mill itself.

  • Design Of Control System For The Ball Mill

    Principle of Operation. The Level and Density Transmitter (FLD) has been specifically designed for extremely difficult Level applications in the Mining Process area like the Outfeed Sump of a Ball Mill, where there could be difficulties in installing standard level transmitters because of a limitation of space, or a very difficult environmental problem.As the key equipment in coal fired power plants, the optimal control problem of ball mill is an important factor affecting the efficient operation of the mill.

  • A Fuzzy Control Method For Ball Mill System Aased On Fill

    The control loop will attempt to add water to Cyclone 1 sump to achieve a particle size of 15 + 300 m. 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.Larger ball and SAG mills, with higher installed power ratings relative to the mill diameter, offer higher efficiency and throughput, round the clock reliability and the opportunity to mine in remote areas. This makes low ore grades economical to grind. ABB has delivered some of the world's largest GMDs • 22 MW GMD for 28’ ball mill.
