FPM S.A. offers modernization services to mills, aimed at the enhancement of their exploitation parameters and performance. Offered modernization takes account for gathered experience of the users and exploits professional skills of our constructors, as well as conforms to environmental protection requirements.
Enhancement of exploitation parameters
| Modernization objectives | Execution methods | Modernization effects |
| Enhancement of the quality of grinding and dust homogeneity | ● Application of highly efficient static or dynamic classifiers ● Application of new generation nozzle rings | Adaptation of a mill to co-operation with low emission burners |
| Performance improvement | ● Substitution of existing grinding system with the one of smaller number but larger balls ● Application of new generation nozzle rings | Increase of the capacity with no alteration of dimensions of the mill and its collaborating devices. |
| Reduction of time constants | ● Application of automatic angle adjustment system for classifier guides | Quick instantaneous changes of the mill performance by re-positioning of its guides with simultaneous adjustment of feeder capacity if rapid jumps of output power of a block are necessary. |
Enhancement of operational indices
| Modernization objectives | Execution methods | Modernization effects |
| Reduction of power consumption | ● Optimization of rotational speed | Reduction of power consumption for grinding |
| ● Optimization of air flow | Equalizing of air flow along the perimeter, reduction of air flow resistance. |
| Facilitating and reduction of maintenance works | ● Application of special maintenance equipment in order to enable quick and safe repairs | Reduction of maintenance cost |
| Extending the lifetime of grinding components | ● Surfacing of grinding components by welding of abrasion-resisting materials | Extension of the overhaul period |
| Extending the lifetime of guide elements | ● Surfacing of guides and side linings on the active side by welding of abrasion-resisting materials | Extension of the overhaul period |
| Improvement of industrial safety and labour conditions | ● Application of protection against opening of the surplus pour chamber ● Application of automatic disposition or automatic surplus pour back-feeding ● Application of hydraulic-aided pressure adjustment in the system for automatic pressure regulation | Elimination of the risk of dust accumulation in the mill and resulting fire hazard |
| Elimination of the most burdensome service work | ● Application of automatic pressure regulation; ● On-line disposing of pyrite ● Substitution of the existing yoke gasket with non-contact, maintenance-free, air sealing. | Reducing of maintenance and repair operations |
