Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to building materials equipment category. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials. Cement kilns are mainly used for calcination of cement clinker, divided into two categories: dry production cement kilns and wet production cement kilns.
Rotational speeds range between and cm/s, depending on the kiln periphery. High L/D ratios and slower rotational speeds are used for wastes requiring longer residence times. The kilns range from 2 to 5 meters in diameter and 8 to 40 meters in length.
FLs ROTAX2#174; and 3base kilns deliver the best in rotary kiln designs. With the ideal temperature profile and material retention time, these rotary kilns play a key role in ensuring optimal quality clinker. Their maximum operating reliability and minimum operating costs help our customers stay competitive as well.

3base kilns. The 3base kiln is a highquality, traditional rotary kiln system. It is characterised by a higher length to diameter ratio compared to the ROTAX2 kiln. It has a balanced design that ensures optimal combination of stiffness and flexibility to minimise kiln crank and misalignment. The ROTAX2 kiln uses tangential sus
Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over 1400#176;C, while the gas temperatures reach 1900#176;C.
The rotary kiln systems of the cement industry destroy these trace components virtually completely. [citation needed] Polycyclic aromatic hydrocarbons (P) Ps (according to EPA 610) in the exhaust gas of rotary kilns usually appear at a distribution dominated by naphthalene, which accounts for a share of more than 90% by mass. The rotary kiln systems of the cement industry destroy virtually completely
Abstract. The rotary cement kiln forms a major part of any cement works. The kiln is a large cylindrical structure where the raw materials are brought together and heated to
Cement rotary kilns are used for calcining cement clinker in the cement plant, which can be divided into dry cement kiln and wet cement kiln. Metallurgical and chemical rotary kilns are mainly applied in the metallurgical industry. As for the lime rotary kiln, it is the main equipment for calcining active lime and light burned dolomite used in
Our cement plant for sale is a new type of dry process cement clinker production plant. The rotary kiln has been used as rotary kiln, whose end is fitted with fivestage cyclone preheater and decomposition furnace.
Rotary kiln or furnace Gordon ( Rotary kiln ) devices that include tubes of iron or steel inside with refractory materials and refractory such as cement or brick insulated and slowly revolves around the horizon and the gentle slope period They do. Lime and dolomite rotary kilns are the most widely used rotary kilns after cement kilns.
Characteristics of Refractory Materials for Hazardous Waste Incineration Rotary Kiln. The main chemical components of refractory bricks used in general hazardous waste incineration rotary kilns include high alumina bricks, magnesia bricks, magnesia alumina bricks, and silica content of AlO in high alumina bricks is relatively high, generally around 70%.
Manufacturing The Cement Kiln. Wet process kilns 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.

Characteristics of rotary kiln: The kiln body is made of highquality killed carbon steel or alloy steel plate and welded; The supporting type and rollers is of ZG35CrMo and 42CrMo steel; The sliding bearing is of nonscraping liner one with large clearance; The driving device adopts hardtoothed reducer, flexible sheet coupling, driven by DC motor;
Cement rotary kiln is the most advanced rotary kiln on the market. After years of technical innovation and practical application, the selection of refractory used in rotary kilns has also accumulated rich experience. More refractory products for the rotary kiln refractory lining, such as spinel refractory, dolomite refractory.
Kilns to produce cement are almost equally old. Now cement kilns can be divided mainly into 2 types: vertical shaft kiln and rotary kiln. The vertical kiln is the older type and its origin dates back to the 5th century AC. Rotary kilns were first used in 1880.
a rotating cylinder lined with firebrick through which the rawmixpasses in counterflow to the combustion gases. the importance of turning over the rawmix in its passage through the kiln, as distinct from the situation in static kilns. the use of a mixture of air and powdered coal to provide heat.
Cement kilns are thermal equipment used to produce cement clinker. Generally, there are two types of vertical kilns and rotary kilns. The characteristics of the vertical kiln are simple equipment, low investment, and high thermal efficiency, but the quality of the calcined clinker is not stable enough, and the production capacity is small. It is generally used in small cement plants.
The characteristics of new type dry process rotary kiln and the basis for selecting refractory bricks (1) Higher kiln temperature and its impact. Dryprocess cement rotary kilns use highefficiency coolers with a heat... (2) Faster kiln speed and its impact. The rotating speed of the traditional
Cement rotary kilns are used for calcining cement clinker in the cement plant, which can be divided into dry cement kiln and wet cement kiln. Metallurgical and chemical rotary kilns are mainly applied in the metallurgical industry.
