Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a powdery coating coarse fodder retrieves regrinding device which characterized in that: the material grinding device comprises a grinding machine 1 and a filtering mixer, wherein the grinding machine 1 is provided with a primary feeding hole 2 and a secondary feeding hole 3, the primary feeding hole 2 is connected with a raw material feeding machine, and raw materials are fed into the grinding machine 1 for grinding and then are fed into a mixing hole 5 of the filtering mixer through a discharging hole 4; the filtering mixer comprises a mixing cavity 6, a mixing port 5 is communicated with the side wall of one side of the mixing cavity 6, a feed back port 7 is arranged on the side wall of the other side of the mixing cavity, and the feed back port 7 is connected with the milled secondary feed port 3; mix material intracavity 6 in horizontal installation filter 8, filter 8 include cylindric main support, circular pan feeding mouth 81 has been seted up to main support one end, the main support is outside spiral puddler 9 through this pan feeding mouth 81 suit, the other end of main support is provided with end cover 82, has seted up material returned mouth 83 on the end cover 82, material returned mouth 83 switches on with material returned mouth 7, the main support surface covering have filter screen 84.

The main bracket comprises a front connecting ring 85 and a rear connecting ring 86, and the front connecting ring and the rear connecting ring are connected into a whole through a pull rod 87.

The opposite surfaces of the front connecting ring 85 and the rear connecting ring 86 are provided with connecting columns, and the filter screen 84 is sleeved and fixed on the connecting column 88.

The material returning opening 83 is arranged in a crescent shape, the outer circle of the oven end cover 82 is arranged, and the material returning opening 83 is located at the lowest point of the end cover 82.
