1. Blockage of cyclone separators, chamber outlets, conveying lines and similar equipment. There are two main reasons for clogging: mechanical problems and humidity. Mechanical issues, whether bridging or reducing flow, are easier to deal with than moisture. Use an air hammer, bridge crusher, or a mechanical device that increases the size of the outlet to deal with these problems.
2. For processes with a dryer outlet temperature of 160°-180°F, the dew point can be in the range of 120°-130°F. If the vessel is at 80°F, there is enough temperature difference to cause heat loss and condensation, causing product to plug or bridge. These problems are usually eliminated if the vessel is insulated and jacketed or heated.
3. Poor heat dissipation of the condenser. This problem is similar to high ambient temperature. Often, the fan is broken or the condenser has accumulated too much dust. just deal with it. Water-cooled models usually do not have this problem.
