introduction： When preparing powder products from suspension，We usually dehydrate by mechanical means first，Then the drying operation is carried out，This procedure significantly reduces production costs，Saved energy。In the process of dehydration，The suspension is converted into filter cake、Paste or high viscosity liquid，Flash dryer is the ideal equipment for processing such materials。 As shown in the figure，The preheated air enters the dryer at high speed in the tangential direction，Under the action of the crusher, a powerful rotating wind field is formed，The wet material fed by the feeder is quickly dispersed、desiccation，Until micronized,These particles are in a state of rotational fluidization due to the action of rotating wind field，make

introduction：Solidworks the Feature Palette（Color palette characteristics）Is a powerful tool，Includes library features and sheet metal parts forming tools。 The so-called library features refer to the storage of some commonly used features into library documents（*.sldlfp），So that a set of features can be inserted one at a time when creating a part，Of course, the properties of these features can be changed at any time。This process is similar to how we put some standard parts into a parts library，These standard parts are then invoked when making assembly drawings，The difference is that library features can only be used to create parts。
