WELCOME TO JIANGSU PENGFEI GROUP CO.,LTD
Hydraulic Φ3 12.5m ISO Pengfei Rotary Kiln System
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.
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.
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.
