Powder mixing device

The invention relates to a powder mixing device including a first mixing unit (1) and a second mixing unit (2); the first mixing unit (1) includes a powder storehouse (11) and a stirring unit (12) arranged in the powder storehouse (11); the second mixing unit (2) is arranged at the lower part of a discharge port (13) of the powder storehouse (11) and is a centrifugal disc (21), and the end part of the centrifugal disc (21) is provided with an annular baffle (22). A powder is mixed evenly by the stirring unit, and the powder is collided continuously by a centrifugal force produced by the centrifugal disc, so that the mixing is reinforced, the powder obtained by the mixing device has good uniformity and is difficult to destroy. 本发明涉及种粉料混合装置。包括混合装置（1）和混合装置二（2），所述混合装置（1）包括粉料仓（11）、设置在粉料仓（11）内的搅拌装置（12）；所述混合装置二（2）设置在粉料仓（11）出料口（13）的下部，其为离心圆盘（21），离心圆盘（21）端部设环形挡板（22）。本发明通过搅拌装置使粉料混合均匀，而通过离心圆盘所产生的离心力将粉料不断的进行碰撞，从而强化了这种混合，因此从本发明的混合装置得到的粉料其均匀性好，且不容易被破坏。
