Common faults and solutions for small spray dryers.

The common fault fault of small spray dryer is one: the main tower inner wall adheres to the cause and solution of wet powder: (1) the material feed speed is too fast, the amount is too large, so that can not be completely dry, the solution is to slow down the speed and quantity of feeding, the feed pump for appropriate adjustment.
(2) did not operate in accordance with the requirements of the instructions, the main tower is not heated, the solution is to increase the dryer import and export temperature.
Fault II: There are a large number of impurity causes and solutions in the product: (1) spray dryer material contains impurities, not filtered out when filtering, small spray dryer solution is to check the air filter, filter according to the situation to replace.
(2) the purity of the material fluid is not high, the solution is to sample the material fluid test, the material fluid in the impurities filtered out.
(3) the device memory has impurities, the solution is to regularly carry out a comprehensive cleaning of the device to remove impurities.
failure three: running powder phenomenon is serious, the product recovery rate is low reasons and solutions: (1) cyclone separator problems, the solution is to check the cyclone separator to see if there are gaps, and air tightness is intact.
(2) low dust removal performance, the solution is to appropriately increase secondary dust removal.
Failure IV: Equipment operating noise is a lot of reasons and solutions: Generally speaking, spray dryer atomization disk and bearings are the main parts of noise, so the two parts should be checked, mainly to see whether the atomization disk is in equilibrium, bearing work is normal and lubricant added correctly, if found damage, should be repaired or replaced immediately.
