We can design and make 2.5m*50m to 6m*95m rotary kiln for cement/lime production. Cement Rotary Kiln / Rotary Kilns / Rotary Kiln

Rotary kiln is refered to rotate calcination kiln, belongs to construction material equipment. Rotary kiln can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials. 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 calcination, which is used for calcining of high aluminum vandal ochre in refractory material industry; for calcining of calotte and aluminum hydroxide in aluminum manufacturer; for calcining of chrome sand ore and chrome powder ore in chemical plant. Lime kiln are used for calcine dolomite and active lime which is used in steel plant and ferroalloy factory.

Grate type cooling machine is a sudden cold type cooler, its principle is: with blower, will lay the ChuiLengFeng in grate board into layer of clinker to sudden cold, make °C plunged by 1,200 clinker temperature of 100 °C below, the cooling of the large exhaust except for secondary air kiln.

Cement in our country is full-fledged development, cement equipment after the development direction of how to judge? Cement as now the most important materials of construction of its investment prospects are bright, the market demand is huge. As people life quality increasingly improved and all of their quality of life of the demand is higher and higher, buildings as the main place of production and life of people.

Cement kiln maintenance mainly include playing kiln skin, demolition brick, masonry and cleaning. In order to try and shorten the stop time, it is to be in commonly kiln kiln, 10-12 hours after cooling make skin and dismantle brick kiln stove temperature, then will be at 90oC above, thus playing kiln skin and dismantle tiles are in high temperature and high dust environment.  In order to enter the smaller spake, and do not want to of kiln hoods conduct additional transformation, asked to play the width and height of the brick machine is small, the weight should be light. At the same time of hydraulic hammer impact power wants big, with quick finish the homework, but also to play moving kiln head castable.  Demolition brick kiln skin can be quickly dozen contrangle dismantle brick, but cannot damage cylinder. And this requires hydraulic hammer impact energy and frequency kiln adjustable steplessly. The machine must be considered in the design of high temperature and high dust circumstances and reliable operation, low failure rate, using low cost. Therefore, the international common practice is no longer the diesel engine driven engineering machinery used in rotary kiln leather down within dozen brick. 1.1 Cylinder by welding sliping structure  Welding sliping structure can improve the cylinder force situation, reducing mill canister weighed, facilitating tube system build, manufacturing quality easy control as well as reducing equipment manufacturing cycle etc, and will become the large tube mill barrel structure development direction, and comprehensively will replace hollow shaft and casting roller ring structure form.  Adopt sliping supporting mill barrel can greatly reduce get machine supporting center distance, make mill barrel bending moment, obviously decreased compared YuZhongKong shaft structure, the maximum stress the same circumstances, mill barrel plate thickness can reduce ~ 10%. Add sliping part of the weight of ease, canister weighed significantly reduced. While reducing the equipment configuration dimensions. Connect sliping adopts thick plates welded together, make the mill barrel manufacturing difficulty reduced. Thick plate quality can be controlled by NDT, welding quality of sliping through has rich manufacturing experience of technicians and factory complete welding process is effectively controlled and guarantee.  1.2 Flat structure base  Sliding shoe bearings adopts the originality of one-piece plate structure base. Make sliding shoe bearings with installation is simple, convenient maintenance, sliding shoe covers sealing effect of simple structure, good advantages .  1.3 Composite wear-resisting steel lining  Enter, discharging device, return feeder and drying storehouse adopts has good abrasion resistance of composite wear-resistant steel lining, enormously increased its for material wear washouts, service life than ordinary steel up 10 times above.  1.4 The overhanging the cantilevered drying storehouse  Using the overhanging the cantilevered drying storehouse, thinning the drying storehouse cylinder thickness, improving grinding storehouse cylinder of stress condition, thus enhancing the safety factor of grinding machine, reduced the mill weight.  1.5 High-pressure thin oil  Sliding shoe bearings lubrication adopts a high-pressure dilute oil, both simplified site equipment layout, convenient operation and control and also reduces the equipment manufacturing cost .
