At present, spray drying has become an important form with rapid development and wide application range in the drying field. It not only has a wide range of products to be dried, but also has a very simple operation. The way to realize automatic processing determines different atomizers and air flow movement modes by different drying characteristics such as heat sensitivity and viscosity of dried materials, as well as the size and granularity division of product particles, It brings convenience for people to operate.

Centrifugal spray dryer has been widely used and welcomed as a device for drying materials and good separation and recovery of materials. When applied in industry, it can be used not only for drying catalysts, but also for drying and recycling different materials such as chemical fertilizers and ceramic raw materials.

Main causes of nozzle vibration of centrifugal spray dryer:

1. Poor cleaning and maintenance watering spray vegetable residue or large shaft bending and deformation.

2. Centrifugal dynamic balance is not good.

Solution:

1. Check whether there is any spray of residual substances, and clean it if found.

2. Find out the abnormal spindle and replace it in time.

3. Reset or replace the dynamic balance centrifugal disc.

Failure is one of the failures of centrifugal spray dryer. There are many forms of failure, among which deformation failure is more common, which is elastic deformation failure caused by mechanical force and temperature.

The components of the equipment will deform under the action of mechanical force, and the relationship between stress and deformation complies with Hooke's law. The fitting tolerance of components is very strict. When the fitting clearance is micron, the elastic deformation can not be ignored. Deformation beyond the tolerance will lead to abnormal operation, and the drying equipment cannot work normally.

When selecting a centrifugal spray dryer, you can judge whether the drying equipment is deformed by calculation. Observe whether there are scratches, scratches or abrasion on the fitting that should not be in contact with each other during the operation of the equipment; It can also be judged by calculation verification.

Of course, the centrifugal spray dryer has not only deformation fault, but also yield fault. This is the failure caused by plastic deformation when the stress of the component increases to a certain degree. We can judge by measuring whether the parts have obvious plastic deformation, distortion, bending and depression.
