  • Calculate Top Ball Size of Grinding Media Equation & Method

    Although it was developed nearly 50 years ago, Bond‘s method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction factors based on mill dimensions and feed characteristics, and the application of the results to designing grinding circuits.

    where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill. The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill size and type can be selected.

  • Mine-to-mill optimisation: effect of feed size on mill

    Modifying blasting practices to achieve a more suitable mill feed size which varies according to the crushing/grinding circuit can achieve up to a 30% increase in throughput. Following an initial benchmarking of an operation’s practices, SRK can advise on how value-added blasting will deliver improvements in both mill capacity and

  • Pelletizing Wikipedia

    The pelletizing of stock feed is done with the pellet mill machinery, which is done in a feed mill. Preparation of raw ingredients. Feed ingredients are normally first hammered to reduce the particle size of the ingredients. Ingredients are then batched, and then combined and mixed thoroughly by a feed mixer. Once the feed has been prepared to

  • IsaMill Wikipedia

    Fine particles are not as susceptible to the centrifugal forces and stay closer to the center of the mill, where they are discharged through the displacement body at a rate equal to the mill’s feed rate. The design of the IsaMill results in a sharp product size distribution, meaning that the IsaMill can operate in open circuit (i.e. without

    The purpose of the cyclones in the circuit is to size the mill discharge slurry. Two product streams are generated by the cyclones; • A fine ‘overflow’ stream which reports to the leach/adsorption tanks. • A coarse ‘underflow’ stream that is recirculated to the mills for further grinding. The most important aspect of cyclone operation is that the particles in the overflow stream
