Many users have been friends for sand dryer sand dryer material clogging problems and a headache caused this problem may be caused by a variety of customers in order to increase the production capacity of sand dryer, often uncontrolled to dryer transport more material, cause the device to severe blockage in the work process, in serious cases can cause paralysis of the entire drying production line; the other cases, it may be due to operational staff do not operate strictly in accordance with operational requirements and cause blockages. Drying equipment specialists following measures will enable the material clogging the sand dryer solve the problem: 1. Set the monitoring machine status can be observed in the location of drying, and then pass the drying process in a timely manner to the control room monitoring machine, so that the operator to grasp the dry state, failure can discover. 2, the use of a composite stream pressure or drying machine and drying machine of this dual function of both the pressure of the airflow dryer and drying machine, when the driving pressure of the pump pressure has not reached the drying with drying air, Stop compressed air to be high-pressure pump is working properly. Similarly, if for some reason the dryer drying occurs when more than often also take this approach to prevent wet material, this method is an additional means of dealing with failure. 3, quick open structure of the dryer using dryer positioning system using the card method, without any tools at the moment can be very convenient assembly and disassembly dryer parts, not only easy to operate, but also save a lot of time to deal with failure . 4, sand dryer filter should select the appropriate filter is to filter impurities in the liquid feed device, select the mesh filter and dryer population Channel and aperture to adapt, often choose mesh diameter filter is dryer into the channel or aperture to 0.2 times. Drying equipment in strict accordance with the instructions to perform the operation, step by step, using the strict implementation of sand dryer equipment in time, it will not be such a problem. Users also can not be so anxious, so drying equipment increased work load, so Houli more serious word, according to chapter operations.
