Detailed Description

In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.

Referring to fig. 1-5, a multi-stage pulverizing apparatus for powder coating according to an embodiment of the present invention includes a pulverizer housing 1, coating disposed in the pulverizer housing 1 for pulverizing,

two first crushing cavities 2 are arranged at the upper half part of the inner part of the crusher shell 1, primary crushing is carried out in the first crushing cavities 2,

the first crushing cavity 2 is rotationally connected with a wall breaking blade 5, the wall breaking blade 5 is the prior art, the coating is primarily crushed,

the top of first crushing chamber 2 week side begins to be arcwall face 21, and the week side slope on arcwall face 21 top is close to broken wall blade 5 downwards for rotatory centrifugal force that produces and whirlwind can blow the effect that the piece passes through arcwall face 21, are drawn into once more and smash in broken wall blade 5.

The crushing chamber 4 of a second that is linked together with first crushing chamber 2 is seted up to the inside lower half of rubbing crusher casing 1, the 4 internal rotations in crushing chamber of second are connected with two intermeshing's bevel gear 6, broken wall blade 5 and bevel gear 6 sliding connection, intermeshing's bevel gear 6 is rotatory, the grinding that goes on the powder, make it reach the demand, 6 top of bevel gear one side is the inclined plane, make the powder can slide through the inclined plane, remove to two bevel gear 6 meshing departments, and then smash.
