Lime rotary kiln is the main equipment of lime production line.It is widely used for many industries like metallurgy, chemical industry, building refractory materials, environmental protection, etc.Great wall lime rotary kiln has many advatages: High Automation Level, Waste Heat be Reused Effectively, Low Energy Consumption and so on.
Rotary kiln is a cylindrical object with a certain slope, the slope is 3 ~ 3.5%, with the aid of the rotation of the kiln to promote the material in the rotary kiln (rotary kiln) stirring, the materials are mixed with each other, contact with reaction. Main reducer. Main motor Number of support
High-torque industrial gear unit solution for use in rotary kilns The heated material in a rotary kiln is mixed by rotation. To create this movement, a single girth gear pinion drive is used, which is located in the cooler part of the kiln. The gear wheel is connected
During normal operation the power is transmitted by the main drive motor to the open gear device through the main reducer to drive the iron ore rotary kiln. The material is calcined from the end of the kiln (the high end of the cylinder) into the kiln.
Parts of Rotary Kiln A rotary kiln mainly consists of a shell, main gear, gear cover, drive, support roller, hydraulic thrust, kiln head sealing device and kiln tail sealing device. Kiln Shell The bottom of the kiln shell is evenly distributed with several floating base plates for convenient installation and replacement.
The main defect of intermittent rotary kiln: 1, kiln flue gas escaping, took a lot of heat, thus making the kiln thermal efficiency decreases, less than about half kiln or a tunnel kiln; reduce labor intensity and improve productivity. Post navigation
Nov 26, 2019· Rotary kiln drive device can be divided into mechanical drive and hydraulic drive. Normally, rotary kiln adopts a mechanical drive. Mechanical drive needs a reduction box with big drive ratio to transmit high-speed rotating of the main motor to small gear, then makes it matches the big gear in the shell to rotate the whole rotary kiln.
