  • Morrell Method for Determining Comminution Circuit Specific Energy and Assessing Energy Utilization Efficiency of Existing Circuits

    This guideline condenses the works of the Morrell method for predicting the specific energy consumption of conventional crushing, High Pressure Grinding Rolls (HGPRs) and tumbling mill equipment and applies them to assessing operating comminution circuit performance. Such circuits include combinations of any of the following equipment: Autogenous Grinding (AG) and Semi-Autogenous Grinding (SAG) mills, ball mills, rod mills, crushers, and HPGRs. The guideline reviews the data required for the analysis, including hardness characterization data generated from the SMC Test® and Bond Ball Mill Test Work Index, presents the Morrell equations and their applications, and provides a worked example. Although the Morrell method can be used in comminution circuit design in greenfield projects, this document provides guidelines to use the method to assess the energy utilization efficiency of existing circuits.

  • Methods to Survey and Sample Grinding Circuits for Determining Energy Efficiency

    This guideline covers surveying and sampling Autogenous Grinding (AG), Semi-Autogenous Grinding (SAG), rod, and ball mill circuits within the normal range of application. The intended application of this analysis is to treat a complete grinding circuit as a singular process block, irrespective of the number of grinding stages or internal classification steps. This approach allows a quick, relatively low-cost assessment of overall grinding circuit efficiency and can identify if more detailed analysis or circuit optimization work is required. Following circuit changes, the same methods can be used to compare the impact on circuit efficiency of varying operating conditions. This approach removes the need to survey internal circuit streams and mass balance around classification stages, greatly reducing labour requirements, survey turnaround time, and costs associated with sampling, sample analysis, and circuit modelling. While the intent of this guideline is not to define a full grinding circuit survey procedure, the techniques described observe industry best practice and can provide a firm starting point to analyze mineral comminution circuits at any required level of detail.

  • Mobile Equipment Open Data Consensus Guideline

    This guideline aims to create a common industry vision for the seamless access and use of mobile equipment data across the mine cycle. It identifies onboard datasets that should be openly available to equipment owners in a real-time, read-only format. It also identifies an initial list of the open data elements for onboard mobile mining equipment. With ongoing advances in mining technology (e.g. growing numbers of autonomous vehicles and greater connectivity and integration), large volumes of data related to the real-time and historical performance of mobile assets. To extract maximum value from these data, however, field operators need to be able to access them. At the same time, OEMs’ intellectual property rights must also be protected. This common vision, therefore, is needed before any industry-wide technical equipment connectivity standards can emerge.

  • Determining the Bond Efficiency of Industrial Grinding Circuits

    This guideline is for measuring comminution efficiency in global mine operations using the Bond method and comprehensive Bond Work Index. This method allows personnel to quantify and compare relative energy efficiencies and offers a mode of benchmarking to observe energy consumption. It is an essential tool for managing the important business (cost) of grinding.  The guideline first presents the method for Bond Efficiency determination, which applies to most brittle materials in their naturally occurring (unscalped) size distributions being treated in size reduction circuits down to an 80% passing size of the circuit product (P80) of approximately 70 µm. It then outlines the equipment and procedures for rod mill, ball mill, and impact crushing bond work index testing.
