Second-hand drum dryer in the process of operation is very easy to appear high temperature, for the full load of second-hand drum dryer, it will produce a certain amount of heat, so second-hand drum dryer in the daily use of the process needs to regularly apply lubricating oil. Secondly, if the temperature of the equipment is too high, it should immediately suspend the high load of the equipment, and then work after the second hand dryer equipment is completely cooled down, otherwise it will affect the service life of the second hand drum dryer, and the second hand drum dryer also needs to stop for regular maintenance.
The pinion reducer and motor on the drum dryer adjust the bite parameters of the pinion and pinion according to the set big gear to meet the requirements of equipment specifications. Position pinion and reduction motor. Mounting the upper lid provides a good balance to the gear matching edges. The drum dryer is a large long body device, so it should stop installing one or two ways to draw the bottom line accurately to place the horizontal line elevation line and the middle target plate on the base target plate, easy to use.
The whole gypsum drying process can be divided into three pieces. *** is wet gypsum in the drying cylinder internal contact with the thermal flow, the use of thermal flow and wet gypsum between the temperature difference to evaporate the water in the gypsum; There is a copy board arranged on the wall of the drying drum, which can pick up the plaster continuously, not only can move the plaster.
If the raw materials are not allowed to be polluted by the environment and the temperature is high, a new type of gas producer can be used as heat carrier. This product is energy saving, environmental protection and high thermal efficiency. If the local energy conservation and environmental protection requirements are very high, and want to save energy, health gas producer will be a better choice. The gas producer in the energy saving level than the combustion furnace at least 20% energy saving, in the artificial also greatly saves a lot of, usually the gas producer has a work can operate, and do not need to keep adding coal, in addition to the gas producer can stop with the use, up to 10 days do not work, the next can continue to use.
若被处理的固体原材料不怕高温，且非产品，能够 允许在处理过程中稍被环境污染，可选用热风炉或排烟道气做为载热体，则能获得较高的体积蒸发率和热效。比如，针对进口水分含量较高的原材料干燥，选用气体进口温度为300度时，干燥器的体积蒸发率为5kg/M3/h热效为百分之30—50。若气体进口温度为500度，则体积蒸发率为35kg/M3/h;热效为百分之50—70。因此针对处理矿石、砂烁、煤、过磷硫酸钙等原材料的转筒干燥器斗带有直接造成排烟道气的燃烧炉，气燃料能够 选用煤、油、天然气、液化石油气等。
If the solid raw materials to be treated are not afraid of high temperature and are not products, they can be slightly polluted by the environment in the process of treatment. Hot blast stove or exhaust gas can be used as heat carrier, so that higher volume evaporation rate and thermal efficiency can be obtained. For example, for raw materials with high moisture content, when the gas inlet temperature is 300 degrees, the volume evaporation rate of the dryer is 5kg/M3/h and the thermal efficiency is 30-50 percent. If the gas inlet temperature is 500 degrees, the volume evaporation rate is 35kg/M3/h; Thermal efficiency is 50 -- 70 percent. Therefore, for the treatment of raw materials such as ore, sand shuo, coal, calcium perphosphate sulfate and so on, the rotary dryer bucket has a combustion furnace that directly causes flue gas exhaust, and the gas fuel can be coal, oil, natural gas, liquefied petroleum gas, etc.
If the dry objects are not allowed to be polluted by the environment, and not allowed to be diluted by the air, the heat should be transmitted according to the drum wall. At this time, the drum is loaded into the brick room, and the tube is passed out to exhaust the flue gas. The intermediate pipe or tube, casing and other surface heat exchangers can also be installed inside the drum, and the metal wall is used for heat transfer. Heat carriers can be exhaust flue gas, water vapor or electric heating. In the raw materials to be dried, only according to the clean gas, the evaporated water will be taken away.
