Description
Technical field
The present invention relates to a kind of powder classifier.
Background technology
Jet Classifier for Super is one kind of dry air grader, and also known as static rank or inertia force classifier, it is different from one
As with rotatable parts gas flow sizing machine, there is no any movable member in its body, its principle be derived from widely known health
Up to effect (Coanda Effect).So also known as Condar Jet Classifier for Super.Micro mist material is broken up in the presence of gases at high pressure
Laggard incident current classifier body, in the presence of Coanda effect, fine grained is close to Condar block, middle particle in middle part, greatly
Particle is away from Condar block.So cause micro powder granule moment be divided into carefully, in, thick three-level.Dust quilt in the collector in downstream
It is separately recovered.General Jet Classifier for Super includes feed hopper and air inlet pipe, and the air inlet pipe is vertically installed in the air inlet pipe
On.However, when powder is poured in the air inlet pipe from the feed hopper, easily causing blocking.And, the jet
Grader is normally only applied to being fixed several classes by powder, and without arbitrarily change, therefore it uses scope smaller.
The content of the invention
Based on this, it is necessary to provide the powder classifier that a kind of air inlet pipe is not easily blocked and the scope of application is wider.
