Rotary Kiln Equipment

      Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to the category of building material equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials. Cement kilns are mainly used for the calcination of cement clinker. There are two types of cement kilns: dry production and wet production. During the operation of the rotary kiln, heating of the roller will occur, and we need to make adjustments in time to prevent malfunctions. Let's take a look at the adjustment methods and issues that need to be paid attention to when the support wheel of the rotary kiln is heated.

     1. Change the gap between the thrust plate and the tiles to friction and heat. At this time, in order to ensure that the center line remains unchanged, the support roller seat can be adjusted first, and then the support roller seat can be adjusted diagonally. It is necessary to adjust multiple support rollers at once. In general, it is impossible to heat all the thrust surfaces of the 12 support rollers, and even less is that the thrust surfaces of the two support rollers in a set of support wheels are hot. Sometimes for a quick adjustment effect, one of the thrust pads in a set of roller seats is heated to make the idler seat move forward (backward), while the other idler seat slightly retracts (enter), but both idler seats move in and out . It is impossible to alleviate the heating problem of the thrust tiles. In order to ensure that the centerline of the rotary kiln does not change, the two inclined roller seats in the roller can be adjusted theoretically.

     2. Control of furnace speed during adjustment: the furnace can be stopped for a short period of time during the adjustment process, but the furnace can also be adjusted during normal operation. At this time, the speed of the rotary kiln should be appropriately reduced, generally around 1r/m. Suitable, especially when the kiln uses an inward jack, the kiln must be rotated slowly or the kiln speed must be controlled at 1 rpm.

     3. Control during the adjustment process: Since the anchor bolts need to be loosened during the adjustment process, the kiln may still be running at this time. Therefore, when the anchor bolts are loose, a jack should be used instead of the load. Always observe the internal condition of the roller seat. At this time, do not drop foreign objects into the roller seat. Before adjustment, check during and after adjustment. Pay attention to the oil spoon when touching the surface of the roller seat with your hands. The impact of sports on the human body.

     4. Control the displacement of the idler seat during the adjustment process: In order to ensure the accuracy in the adjustment process, it is sometimes necessary to remove the axial stop of the idler seat. During the adjustment process, two idlers should be used for each idler seat. Yami, each adjustment is between 0.2-0.35mm.

     5. Observation and monitoring after adjustment: After adjustment, please pay attention to whether the gap between the thrust plate and the tile has changed, and whether the temperature changes of the other rollers in the same gear and the other two gears in the same gear are the same . Abnormal changes, whether the temperature of each tile is reasonably adjusted. Fluctuation monitoring during normal operation: During operation, the bearing of the idler should pay close attention to the changes in the end surface of the idler shaft, the surface of the idler shaft, the oil temperature, and the working pressure. Whether the angle of the hydraulic gear is appropriate and whether the support roller moves normally.
