A cement kiln produces no ash The inorganic components from the fuel bond with the inorganic compounds of the clinker or kiln dust Lead barium chromium nickel and other metals become a fixed part of the cement structure As the fuel burns the heat causes the molecules of fuel air and raw materials to break apart
Rotary Kiln 8 diameter X 92 long manufactured in 2013 by Metso complete with gas burner to 80mm BTUs per hour Last used on phosphate rock in research and
Rotary kilns used in the cement industry are much larger in diameter and longer in length than the previously discussed incinerator The manufacture of cement from limestone requires high kiln temperatures 1400°C and long residence times creating an excellent opportunity for hazardous waste
Even a small crack can allow heat to reach the rotary kiln shell It is important to routinely temp gun the exterior of the rotary kiln shell ensuring that the temperature is consistent for
Specification of rotary kiln by various processes It has been developed for use in cement calcining but today rotary kilns are used in a variety of thermal processing applications such as mineral extraction metal smelting and waste incineration The most commonly used field is limestone processing for raw material firing to produce cement
CEMENT ROTARY KILN Questions Answers Question1 What is the maximum continuous shell temperature a kiln stands without permanent damage to the shell Answer1 The maximum recommended kiln shell temperature varies by plant by country and by kiln manufacturer despite the fact that most kiln shells are made of low alloy carbon steel

Cement Rotary Kiln is made of drum support bearing hydraulic thrust device transmission movable kiln head kiln end seal and pulverized coal injection device The kiln body is slightly inclined to the horizontal and is supported by hydraulic thrust roller and roller bearing
The picture photo 1 gives a schematic overvieuw of the system manufactured to treat the waste in a rotating drum we use a counter current rotary kiln There are 2 different types of rotary kiln cocurrent rotary kilns and counter current rotary kilns Read here more about the different types of rotary kiln
Cement rotary kiln as the main equipment of dry cement clinker production line is the most efficient cement calcination equipment In appearance the kiln body is inclined to a certain level The whole kiln body is supported by supporting roller and equipped with thrust roller to prevent it
The rotary kiln consists of a tube made from steel plate and lined with firebrick The tube slopes slightly 1–4° and slowly rotates on its axis at between 30 and 250 revolutions per hour Rawmix is fed in at the upper end and the rotation of the kiln causes it gradually to move downhill to the other end of the kiln
Even a small crack can allow heat to reach the rotary kiln shell It is important to routinely temp gun the exterior of the rotary kiln shell ensuring that the temperature is

The original rotary cement kilns were called wet process kilns In their basic form they were relatively simple compared with modern developments The raw meal was supplied at ambient temperature in the form of a slurry A wet process kiln may be up to 200m long and 6m in diameter
Rotarykiln feed consists invariably of small sized stones generally not exceeding 50 mm Such kilns are ideally constituted for heating fine material eg 6–12 mm diameter since their action causes the fine material to fall rather than slide continually through the flame thus transferring heat by convection to a large exposed surface area
This 11 X 310 FullerFLS Rotary Kiln has already been dismantled and is ready to ship Formerly used for recausticizing lime it has 4 support stations and is equipped with satellite coolers It was new in 1998 and has been used for less than 1 year total To see other kilns go to our
Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed The kiln is set at a slight slope to assist in moving material through the drum
