Floating roller grinding mill is designed for ior performance in grinding process. It use 40 to 50 % less power than ball mill for grinding dolomite, calcite, clinker & granulated blast furnace slag. For grinding of fly ash floating roller grinding mill use 50-60% less power than ball mill. It have shown 8 to 10% less power consumption than vertical roller mill.
Floating roller grinding mill is effective on large range of feed material size (15mm to 42 microns).
Space saving is very special feature of floating roller grinding mill. It needs less area and less civil structure than other grinding systems like ball mill, and roller press.
Application
Floating roller grinding mill is suitable for grinding lime stone, clinker, dolomite, calcite, granulated blast furnace slag, fly ash and various other building materials for its large range of feed material size (15mm to 42 microns ).
Features and Benefits
- Floating roller grinding mill have flexibility to do changes in grinding elements to suit the feed material characteristics and specifications. Configuration of floating roller grinding mill can be modified to match the variation in feed material.
- Grinding elements needs no reversal or material build up to achieve optimum performance.
- Grinding elements are made of hard material (60 hrc) to have longer life in turn reliable performance of machine.
- Replacement of rollers and grinding rings is done in 48 working hrs and machine is ready for non-stop run of minimum 180days.
Fly ash floating roller grinding mill process
Floating roller grinding mill provide effective pressure and more active contact areas for grinding process which result in reduced wear on grinding surfaces. Grinding elements give more life and do not require re-grading, change or material rebuilding in roller liner and table liner. Big metallic chunks coming out of the roller & table liner is avoided. Wear rate on grinding elements (roller & ring) is lower.
Floating roller grinding mill performs well in stand-alone mode and also in conjunction with ball mill, roller press & pre-grinder. It will enhance production and productivity of existing grinding systems at minimum cost.
Cost of new grinding projects can be reduced substantially by use of floating roller grinding mill.
Floating roller grinding mill gives ior performance for grinding fly-ash and granulated blast furnace slag for its special design features.
Floating roller grinding mill maintenance
- Floating roller grinding mill have well designed components to provide trouble free operation and minimum attention while operation.
- Floating roller grinding mill is having evenly distributed load in machine to reduce vibration in operation and load variation on drive and machine components.
- Floating roller grinding mill needs least maintenance while in operation and minimum time for all planned maintenance jobs.
- There is key-less fitting in grinding mechanism to reduce dismantling and assembly time. Complete replacement of grinding elements is done in 48 working hrs.
- Bearings are fitted with withdrawal sleeve and adapter sleeve to facilitate maintenance activities in floating roller grinding mill.
- Centralized lubrication systems are incorporated to optimize machinery lubrication.
- Floating roller grinding mill do not need in-situ material build up on grinding elements, grinding media regarding, reversal of liners and correction in liner position. Machine is available for non-stop operation of 180 days after maintenance work.
- Bearings in floating roller grinding mill are designed for 50000 working hours.
