100m Rotary Kiln

The structure of rotary kiln

• Kiln shell, we buy the steel plate from Bao steel, Wugang steel, the first-class steel plant in China to guarantee the quality because the shell shall resist high temperature. We have the automatic cutting machine, rolling machine which can roll 120mm thick, and skilled welders to weld the shell section. Different instruments to inspect the welding of shell.Ultrasonic test and magnetic powder test to check where is the crack and the crack position.
• The supporting unit:the supporting unit can have two,three or four,normally cement plant rotary kiln have three, lime plant have two, nickel ore plant have four or more, it depends on length and other design index of the rotary kiln.
• Tyre, most of our tyre are castings tyre ,we have our own casting company branch, which branch can make castings maximum 190t.we can also do the forging tyre,so if you need the spare parts like tyre,please try to contact with me,we can produce as per your drawings
• Pads. Such pads is to avoid the temperature difference of the tyre inside and outside surface and eliminate the expansion and contraction of the tyre to extend its lifetime.
• Girth gear. We can produce spur gear, helical gear,so if you need the spare parts like girth gear with spur gear,helical gear or bevel gear,please try to contact with me,we can produce as per your drawings
• Spring plate: to connect the girth gear and shell.
• Hyraulic thrust roller: besideds the hydraulic thrust roller,there is also mechanical thrust roller which one does not use much more now. Such unit can push the tyre and supporting roller to be worn on the whole width to extend their lifetime.
• The sealing unit:Kiln inlet and kiln outlet. We have designed from graphite block sealing to fish scales sealing. Fish scales sealing is much more simple and convenient.now most of rotary kiln we adopt fish scales sealing/

• Our company is the biggest manufacture base for the rotary kiln we have manufactured the vertical kiln from 1983, and rotary kiln from 1994,till now we have already manufactured for 26 years.Our chairman Mr Wang Jiaan make a lot of investment on arranging technical team to research, cooperate with the famous research institute and college for many years to improve the technology of our rotary kiln. From the wet process to dry process, from size around 2 meters to 6 meters.from cement plant other industry filed. From two piers to four piers.Now our rotary kiln are the leaders for rotary kiln in cement plant with capacity from 300tpd,700tpd,800tpd,1000tpd,1200tpd,1500tpd,2000tpd,2500tpd,3000tpd,3500tpd,4000tpd,5000tpd, 8000tpd ,lime plant capacity from 300tpd to 1200tpd.300tpd,400tpd,600tpd,800tpd,1000tpd,1200tpd.Nickel ore plant from 50000tons 150000tons.our such rotary kiln with advanced technology and high automation level can increase the running rate 3-5%,production has been raised by 5-10%, and heat consumption has been reduced 15% down. Till now we have sold to more than 200 hundred clients in the domestic clients in such filed and more than 100 hundred clients in foreign countries. we also cooperate European countries for the rotary kiln manufacturing.
