Regularly pass through observation door observes the isolation screen sifter and blocks up the condition, when appearing blockking up, in time clears up

Compared with the prior art, an keep apart mill ore discharging case of bold medium possess following advantage:

(1) the utility model has the advantages of novel and reasonable design, simple structure, convenient manufacture and use, low investment cost, and can effectively isolate massive ore, massive broken steel balls and even steel balls, thereby avoiding influencing the normal production of the next procedure, further prolonging the service life of the conveying pump in the next procedure, saving the production cost, avoiding the occurrence of sudden failures such as the blockage of the impeller of the conveying pump, the shaft breakage and the like, and ensuring the stable and smooth operation of production;

(2) the utility model forms a screen seam with a small upper part and a big lower part by arranging the inverted-splayed isolating screen, and larger mineral aggregate or medium can easily roll down to the lower part of the isolating screen and enter the slag collecting box, thereby effectively avoiding the screen seam from being blocked by the ore or the large medium, further avoiding the need of frequently cleaning the screen surface of the isolating screen and reducing the labor intensity of posts;

(3) the utility model is convenient to use and maintain by arranging the upper and lower box bodies connected by the upper and lower bolts;

(4) the slag collecting box of the utility model is set into the inverted trapezoid shape, so that the massive ore or the medium can be conveniently sent into the slag discharge pipe for recycling.
