The kiln is usually turned by means of a single girth gear surrounding a cooler part of the kiln tube, but sometimes it is rotated by driven rollers. The gear is connected through a gear train to avariable-speed electric motor. This must have high starting torque in order to start the kiln with a large eccentric load. A 6 x 60 m kiln requires around 800 kW to turn at 3 rpm. The speed of material flow through the kiln is proportional to rotation speed, and so a variable speed drive is needed in order to control this. When driving through rollers, hydraulic drives may be used. These have the advantage of developing extremely high torque. In many processes, it is dangerous to allow a hot kiln to stand still if the drive power fails. Temperature differences between the top and bottom of the kiln may cause the kiln to warp, and refractory is damaged. It is therefore normal to provide an auxiliary drive for use during power cuts. This may be a small electric motor with an independent power supply, or a diesel engine. This turns the kiln very slowly, but enough to prevent damage.The rotary kiln ...
... tyre works under great force and high temperature . Therefore, the machine has serious requirement on oil . Now , we choose synthetic lubricating oil as the carrier of HF-high temperature tyre lubricant , this kind of oil is lower than 100℃, its viscosity is above 100 centistoke , and flash point is higher than 320℃. At the same time , we choose composite high-temperature lubricate grease with dropping points more than 300℃. Actually , the choices of Rotary kiln Tyre"s maintenance work should based on practical situation , different types of rotary kiln equipment have different choices on lubricant , their maintenance also have different advantages and disadvantages . The above are only several methods , if you want more detailed information , please contact with our Website service , We wholeheartedly at your service.Henan Hongxing Mining Machinery Co., Ltd is a joint-stock mining machinery manufacturing enterprise integrated in scientific research, production and marketing of rotating drying kiln, cylinder rotary kiln and other commonly used mining equipment, welcome to visit and cooperate with us.
