MIRL Mill Simulatorany item on the list to start drawing the circuit. There are six unit process that the user can add to their circuit. They are as follows: 1. Feed 2. Ball Mill 3. Semi-Autogenous Mill (SAG Mill) 4. Hydrocyclone 5. Sump Pump 6. Screen Apart from these six unit processes, there are some added features that makes the simulator easy to use. They necessarily do not exist in plants, but help the
Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps

Grinding in Ball Mills: Modeling and Process ControlKeywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc. The applications of ball mills are ubiquitous in
Modelling and Simulation of the Santa Rita Mine Simulation 6 considered the two-stage ball milling concept, including one flotation stage between the two milling stages, as well as one after the second ball milling stage. The strategy here was to reduce Ni mineral overgrinding and therefore the Ni losses in flotation. In other words, the two existing parallel ball mills would be converted to an operation in series. Simulation 6 was based on
Grinding Circuit - an overview | ScienceDirect The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls Rosas et al., 2012). Autogenous grinding or semi-autogenous grinding mills
The circuit is direct with an overflow ball mill, 5.2m of diameter and 7.8m of length, and classification is accomplished by a cluster of 6 cyclones of 500mm diameter. The geological model indicated high ore competency in deep mine levels. The mill was sized to meet this future demand. During the first years the grinding circuit will be operated with a less competent ore.
