Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in the figure 1-2, the steady flow bin of the roller press for reducing the material segregation phenomenon is characterized in that the roller press 2 is arranged at the bottom of the steady flow bin 1, a feeding scraper-trough conveyer 3 is arranged at a feeding port 4 at the top of the steady flow bin 1, and an included angle between the feeding scraper-trough conveyer 3 and the steady flow bin 1 is 45 degrees. Lie in the vertical striker plate 5 that is equipped with in feed inlet 4 one side in the stationary flow storehouse 1, and striker plate 5 is relative with the unloading direction (the arrow indicates the direction in fig. 2) of pan feeding chute 3, and the length of striker plate 5 is unanimous with feed inlet 4 size, and the below of striker plate 5 is being equipped with to feed inlet 4 level and is connecing flitch 7, and the length that connects flitch 7 is greater than the length of striker plate 5, and the width that connects flitch 7 is greater than the width of stationary flow storehouse 1 feed inlet 4.
