Ciros’s knowledge and know-how inside grinding, flotation, divorce, dewatering and automation we can confidently partner customers inside the supply of individual units of products or turnkey shipping to mining and also industrial mineral crops. In grinding, Ciros has inherited an existing lineage from Morgardshammar, Scanmec and Ciros spanning over 100 years. All these brands have become Ciros Grinding. Ciros’s updated models are developed coming from these years regarding experience -yesterday’s practical experience is used in the present designs to produce the proper product, in the proper quantity. Ciros’s array of grinding mills contains Semi-autogenous (SAG) mills. Autogenous (AG) mills, ball mills, pebble mills and rod mills. All mills can be purchased in various designs and sizes to fulfill customers’ requirements.

Comprehensive studies and materials tests determine optimum work type and size

Knowledge and also technology count, dimensions the mill proper first time

Correct sizing regarding grinding mills needs in-depth knowledge and experience of crushing and beneficiation techniques. Ciros’s metallurgists and also application engineers are usually acknowledged experts inside these fields. Parameters for instance Ball Mill Perform Index (BWI), Rod Mill Perform Index (RWI) and also Crushing Work Index (CWI) are necessary in arriving on the optimum mill design to get a given application. Dimensions distribution in nourish, product and materials behavior may also be important considerations.

The first area of the sizing process requires standard application data. The calculations determine the energy which must be employed at the work to grind the particular ore, at the particular specified feed fee, from one size distribution to a new. Using our blended expertise in mincing and specially produced sizing programs, Ciros will make these calculations and recommend the proper mill type and size to get a given application.

Ore testing to the extra edge

First-hand familiarity with the material being processed is needed for the successful layout and operation regarding any mill. Ciros provides test facilities regarding material mineralogy and also liberation analysis, also complete vitamin processing facilities inside our own R& N center. Where additional data is necessary, we have proven co-operation with reliable test centers around the globe.

Full array of mills

The demands regarding hard rock mining and industrial nutrients operations require numerous grinding mills being available. AG and SAG mills are currently the industry common for primary milling. Ciros provides high aspect or perhaps low aspect AG SAG mills to fulfill any milling need.

Autogenous (AG) and also Semi-autogenous (SAG) Mills are for major grinding of run-of-mine ore or perhaps primary crushed ore. Those two types of primary mills will be the most frequent kinds and Ciros is entirely able to providing the total size and power range around the very greatest.

For main, secondary and tertiary grinding

Ball Mills are generally used for supplementary and tertiary milling. The designs tend to be either overflow or even grate discharge. Ball mills are the most typical secondary mills with regard to preparing the material for that following concentration procedure.

Rod Mills are mainly for that primary grinding associated with crushed ore within the size range as much as —50mm for gentle materials and —20 in order to 30mm for tougher materials, and with regard to preparing feed with regard to secondary ball generators.

Pebble Mills are mostly employed for secondary grinding, in which the contamination of prepared mineral or the actual minimizing of operating costs because of high media as well as liner wear tend to be of high significance, and where the actual ore is effective at forming suitable small stones. The application range is comparable to that of golf ball mills.

Complete options for both moist and dry grinding

In milling, a wet process is most often used, since the majority of the downstream operations — flotation, permanent magnetic separation and leaching — tend to be wet processes. Nevertheless, there are dried out processing applications that dry milling may be the necessary grinding technique. Ciros can supply grinding solutions with regard to both dry as well as wet applications.

Mill designs for each need

Ciros milling mills are size, designed and constructed for rugged responsibility and operation within the harshest of conditions. Different applications demand various mechanical designs and designs. Ciross abilities and expertise include both trunnion-supported generators and shell-supported generators. Either design is complemented by having an optimized drive answer, selected for the particular conditions to end up being encountered.

Mill Bearings

The type associated with support bearing is selected based on the intended responsibility, mill size as well as environmental conditions in the installation site. Ciros offers generators supported on a number of bearing arrangements: diary, spherical roller, hydrodynamic as well as hydrostatic multi-pad kind bearings.
