Now, usually we see the rotary drum dryer as the manufacturing is simple and convenient, sieve ring layout almost all levels, due to the small capacity of extruded feed, as usual after drying products 0.28-0.34t / m3, the same kind of feed pellets shape, there are some differences, coupled with the secondary vibration sieve on some feed in the drying process, to remain in the dryer, it is difficult to clean exclusion, resulting in feed conversion time is too long, and a second species should begin to be discharged from the first kind of dry residue of approximately 15-20kg miscellaneous feed material, and re-expanded, here affects the yield and quality of the finished product. Therefore, shortages of extruded feed processing is required sieve rational layout design, the multi-level ring sieve designed to channel angular spiral plane is 1.5 °, which also can eliminate the post of the drying apparatus for drying Problems remain in the material within the body of the. The dryer manufacture and use of all kinds of problems you might encounter, you can find a clear solution, through a variety of cases, summary dryer equipment daily management of maintenance and management experience to their own experiences, to abandon the theory of preaching, focusing on examples of analysis, focus on details, authentic, vivid and easy to read, very practical operability. The following we have to feed the dryer after drying work using residual phenomenon of how to deal with the inner wall to make a settlement more conducive to the rational design of sieve to eliminate residues. Identify the root causes of the phenomenon of residual feed after drying sieve transformation, technological innovation, and we need to always focus on development issues. Sound technical solutions and outstanding achievements in the development pace of the most perfect drying effect. A fundamental reason is the innovative equipment makes more perfect in the original basis, for the greater development, improvement of existing equipment shortcomings exist, to find the starting point of the various issues, longer-term organizational restructuring, at the same time must also be From the standpoint of long-term practice of using the device to achieve the best results. All in all, at different stages of production dryer equipment you need to do different things, as the time goes on constantly changing device also has a new breakthrough.
