Additional technical support is provided by regional Grinding mill Centers, each staffed with experienced personnel who carry out project management, design, manufacturing, procurement, delivery, erection, and commissioning for the full Liming mill range. These centers are located in Iran,Russia,Kazakstan,Spain,Panama.
The process of selecting a grinding mill is not entirely straightforward. Using our combined expertise in grinding mill and specially developed sizing programs, Liming can offer relevant calculations and recommed the correct mill type and size for a given application.
To obtain valid results, the grinding mill characteristics of the ore must be well understood, and parameters such as the Ball Milling Work Index (BWI), Rod Milling Work Index (RWI), Crushing Work Index (CWI), feed top size/distribution, and the desired product size distribution must be known.
The first part of this process involves standard application equations. These calculations determine the power which must be applied at the mill drive to grind the ore — at the specified feed rate — from one size distribution to another. We can then help you to select a mill that develops the required power.
Liming’s engineers use sophisticated application software to perform these complex calculations. The application parameters can be further verified with pilot scale grinding tests on prepared ore samples. These tests offer the greatest possible assurance that the grinding circuit selected will perform as predicted.
Services and product support
To ensure quality product service and support, Liming has a worldwide sales and service network.
Liming’s specialists make certain that the mill is properly erected, verify that bolted joints are torqued to specified levels, align mill bearings and drive equipment, calibrate instrumentation, and verify proper performance of the lubrication equipment and other auxiliaries. They also will commission the mill and verify process performance.
After commissioning, your local Liming office provides:
ongoing product support with promptly delivered high-quality replacement parts
complete process evaluations and performance diagnostics
maintenance inspections
liner wear measurements and profile development
alignment checks
gear reversals
other mechanical services including complete mill reconditioning.
