The Working Principle of Rotary Dryer and Kiln
Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is used in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcimine. Rotary kiln is used for calcimine of high aluminum vandal ochre in refractory material industry; for calcimine of calotte and aluminum hydroxide in aluminum manufacturer; for claiming of chrome sand ore and chrome powder ore in chemical plant.
Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.
The rotary kiln in the application area, the numbers to be most cement industry. The whole process of cement produce summarized as "two ground a burn," with "a burning," is made by grinding good raw material, in the high temperature of kiln under the action of the process of burning become clinker. The equipment is also widely used in metallurgical, chemical, building, refractory material, environmental protection, and other industries.
The rotary kiln under high temperature overloaded alternating slow operation, and its annex equipment maintenance and thermal rail system related to the level of control of the rotary kiln working safety and efficiency. Therefore, rotary kiln cement produces the host, commonly known as the cement factory "heart"
Rotary kiln cement industry forged in the main equipment burn the cement clinker. The stand or fall of sealing device directly affects the thermal rail system and run the rotary kiln capital. Strengthen rotary kiln daily maintenance data analysis of the pack; be helpful for equipment management work.
Multi-use machine and flexible application — It has unique feeding and crushing structure and many kinds of shapes of crushing cavity, which can very conveniently realize conversion between "Using stone to hit stone" and "Using stone to hit iron block", thereby solving the difficulty of multi-use machine. If application of VSI crusher is to be changed, it

    The theoretical heat (the standard enthalpy) of reaction required to make high-calcium lime is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient. The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heat-up and cool-down cycles of the batch kilns. The first were simple shaft kilns, similar in construction to blast furnaces. These are counter-current shaft kilns. Modern variants include regenerative and annular kilns. Output is usually in the range 100-500 tons per day.…

    Mobile Rotary Kiln allows the soil at rig sites, fuel dumps, gas/service stations and numerous other potentially contaminated areas to be cleaned up more economically and efficiently. The Mobile Rotary Kiln is a self-contained trailer mounted unit that can be delivered to the contaminated site and operated until the clean up is complete. It can be moved site to site with minimal set up time. The kiln operates through a maximum temperature of +2,520°F (1700° C) and can process 10 to 15 tons of contaminated soil per hour. In addition, the Mobile Rotating Kiln can produce cement clinker and various densities of expanded clay. The manufacturer claims that the unique ability of the kiln to produce such valuable byproducts could play a very important role in third world countries by allowing them to become more self sufficient and eventually produce export products.…

    Rotary drum dryer is the device that is used to heat and dry the materials. Rotary drying machine is generally applicable to granular materials and it can be also used for the drying of some part of sticky pasty materials or the materials with high water content. The dry moist materials are transmitted by belt conveyor or bucket elevator to the hopper and then getting into the feed end trough feed pipe.1.The dryer is a tilt rotary cylinder which the materials are added from the high end of the cylinder; during the continuous rotary motion of the sand dryer, the materials are in progressive movement from the high-end to low-end, so sand dryer is a transportation equipment.2.Dryer is also a combustion equiment. The pulverized coal powder is sprayed into the sand dryer by the sand drying blower head. The combustion heat is transferred to the material in the three basic ways of radiation, convection and conduction. As fuel combustion equipment, sand dryer has a broader space and thermal field, can provide sufficient air, install excellent combustion apparatus to ensure full combustion of fuel and provide the necessary heat for clinker calcination.3.Dryer has the heat exchange function. Sand dryer has a relatively uniform temperature Session which can meet the requirements of exchanging heat during each stage of the cement clinker formation , in particular Alite mineral generated requirements.4.Drying machine has a function of chemical reactions. In the formation process, the clinker has a series of physical, chemical reaction. Sand dryer can meet the heat, temperature requirements of different minerals in phases, but also meet their time requirements, with all of those features, it is the ideal chemical reaction device.The feeding pipe slope should be greater than the natural inclination of the material, so that the material can smoothly get into the dryer. The dryer cylinder is a horizontal line slightly inclined rotating cylinder. Material is added from the upper…

    Rotary kiln outside decomposition technique is the dry hollow kiln, made Bohr kiln, suspension preheater technology developed on the basis of a relatively advanced core technology. The original rotary kiln outside decomposition kiln for straight cylinder, this kind of kiln makes preheater heat exchange and decomposition furnace precalcining efficiency low, resulting in kiln system low yield. But after years of production practice has proved efficient kiln outside decomposition rotary kiln high production efficiency, low energy consumption, stable operation. support rollers, bearings, tires and support rollers are used to ring to support the weight of the rotary kiln used. Tire ring is set in the kiln shell, between it and the kiln shell is not fixed, rotary kiln shell and tire ring plus a piece of iron between the separated ring and the tire to retain a certain gap between the kiln shell, not too much not too small. If the gap is too small, the expansion of the rotary kiln shell limited by the tire ring, brick kiln easy to destroy. If the gap is too large, the kiln shell and the relative movement between the tire ring, friction is more interest, but also make an elliptical deformation of the rotary kiln shell is more serious.…
