limestone pellet rotary kiln

ROTARY LIME KILNMAINTENANCE Precipitated calcium carbonate, commonly calledlime sludgeor lime mud, is produced when sulphate green liquor is causticized with lime. For many years thislime sludgewas considered a waste product and was dumped into rivers or waste ponds, or used for fill around the plants.

Arotary kilnis a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced usingrotary kilnsinclude: CementLimeRefractories Metakaolin Titanium dioxide Alumina Vermiculite Iron orepelletsThe rollers must support thekiln…

We work with cement and activatedlimestoneproducers, agricultural feed and rendering manufacturers, the print and toner industry, activated carbon producers, waste incineration plants, biomass and woodpelletproducers, gold mines, and anyone else who uses arotary kiln, calciner, cooler, or dryer as part of their production process.

Therotary kilnprovides constant mixing of thepellets, bringing all thepelletsto the same temperature. In a straight grate, thepelletsat the top of thebedare “over cooked” and those at the bottom are “under cooked”. Higher quality means fewer fines, better reducibility and less variation in compression strength.

Rotary kilnThe final induration of thepelletis accomplished in arotary kiln, wherein the principal heat transfer mechanism is radiation from the system's main burner. The process system is designed so that material transfer from the grate to thekilnoccurs when the material on the grate is sufficiently preheated to have the requisite indurate strength for subsequent processing in therotary kiln.

Thelimestone pelletizingprocess adds moisture to thepellets, making drying a necessary step before storing or bagging the product.Rotary dryersare a common drying choice due to their efficiency and ability to handle a high amount of volume and variability in feedstock.

Rotary kilnswork by processing material in arotating drumat high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. Thekilnis set at a slight slope to assist in moving material through the drum.

Pelletized limestone, often referred to aspelletized lime, is created whenlimestone rockis crushed into a powder and then granulated. Thepowdered limeis ground to a very fine consistency, allowing the product to dissolve quickly and start working fast.

The reason for the slow desulphurizing reaction of self-fluxingpelletsin thekilnis assumed to be the absorption of SO2 by freelime. In actual operations it was confirmed that the effect of indurated temperature onpelletquality is very large, as indicated by this test. Experimental use of self-fluxingpelletsin blast furnace burdens

The rotary dryer reduces the moisture content of the granules to a predetermined level, leaving them in their final form. A cooler may follow the rotary dryer if necessary. Rotary dryers utilize direct contact with a heated air in combination with a tumbling and cascading action to efficiently dry limestone pellets.
