The utility model discloses a granule homogenizing board device which relates to the granule homogenizing board device which is arranged in a storage tank for using and is capable of evenly mixing the granules. The granule homogenizing board device comprises a homogenizing board which is fixed below a feed gate, wherein, the homogenizing board is fixed at the position with a distance of 10 to 60cm to the feed gate and takes the shape of a pot lid which raises gradually from the margin to the middle, an included angle of the surface tangent of the homogenizing board and the level ranges from 5 degrees to 60 degrees, and the projection area of the homogenizing board is not less than the area of the feed gate. The granule homogenizing board device has the beneficial effects that; by adopting the homogenizing board device, the structure is very simple, the installation and the connection are easy, the special pot lid structure with the middle raising can effectively lead the granules to be sputtered evenly, thereby not only solving the problems that the color and the performance of the plastic granules are not stable and even, but also simplifying the technological processes, spurning the traditional roll-mixing technology and leading the cost to be reduced largely and the efficiency to be improved.
