Ore dryer is widely used in industries such as construction material, metallurgy, mining, chemical industry, cement, etc. It is used to drying material such as the ore, acetylene sludge, limestone, clay, etc. Ore dryer owns the advantages of reasonable design, excellent manufacturing, stable performance, advanced technology, high output, low energy consumption, high degree of automation, etc. It makes important contributions to the mining resource develop and construction. For the sake of ourselves and efficient work, when using the ore dryer, we must take the right way and do not operate it based on our experience blindly. So what is the operating process of ore dryer? Today let us learn about operating process of the ore dryer together.
1. Empty machine commissioning: the installed ore dryer should operate without load for no less than four hours. Abnormal situations on the commissioning should be solved in time.
2. Test run with load: after the empty commissioning, fasten all the connecting screw again, then check and complement the lubricating oil. Take the test run after commissioning is normal.
3. Preheating: ignite the hot air furnace to preheat the dryer machine, meanwhile, start the dryer machine. To avoid the barrel bending, heating the dryer machine when it is not rotating is not allowed.
4. Feeding: according the preheating condition, add the wet materials into the barrel of the dryer machine gradually. Based on the moisture content of discharged material, increase the feeding amount gradually. The preheating of ore dryer needs a process. The hot air furnace needs a preheating process as well and do not burn in big fire to avoid local overheat and uneven thermal expansion damage.
5. Drying: the combustion value of the fuel, the heat preservation quality in every part, the moisture content of the wet materials, the uniformity coefficient of the feeding amount affect the quality of the dried product and the fuel consumption. Therefore, making every part get the best status is an sufficient way to improve the economic profit.
6. Shutdown: when stopping the device, we should stop the hot air furnace firstly, then stop the drying barrel after cooling the temperature close to the outside world. Do not stop the device when it is in high temperature status to avoid the barrel of the ore dryer from bending.
