Feed puffer use should pay attention to the requirements of the sieving equipment and control. After the material is crushed, which will be mixed with a small number of large particles, while the entire process also has some impurities, in addition to the crushing process, the fiber in the material due to the smaller capacity, there is also a part of the fiber is not crushed well. These impurities and fibers in the extruder extrusion process part of the "melting", but there is a part of the die hole before reaching the die hole will be blocked die hole, some fibers even through the die hole, there will be a part of the cutter hanging on the cutter, thus affecting the cutter on the cut of the puffed products, so that the cut of the puffed particles of the aesthetics of the decline.
Therefore, the feed puffing machine puffed chemical section before the process also needs to set a good sieving equipment. Currently a good practice is to configure a high square sieve in the crushing equipment, and in the material to be expanded warehouse needs to be screened again through the high square sieve to prevent the process of impurities mixed into the material.
