Exploration and improvement of the third generation of sand making machine

For the third generation of sand making machine wear not normal wear and tear, our company made several comparison test, a test, regulate the total into the feed to ensure certain opening, with the feed rate increases, expected to throw the first wear position slightly increased, but still focus in a position to wear, wear is intensified. Test two, to ensure that the larger feed rate unchanged, adjust the overflow port, the amount of material increased, into the third generation of sand machine rotor volume reduction, production rate decreased, wear is also reduced, but the wear position change is not big; the amount of material is reduced, the increase in the amount of rotor, wear. But wear position change is not big.
First of all, in order to extend the butt ends and side expected to throw the first life. If you can not wear and wear and tear of the site exchange. Can prolong the half life. It is easy to think of the original block to throw the first made two or three block is arranged. And it can be up and down. The original with two bolts fixed. Changed into two, each with a single screw fixation is easy to loose, is obviously not ideal, if can be divided into three pieces and three block assembly are stuck, it is not easy to loose, but the third generation of sand making machine rotor clearance height is insufficient, tentative. Heightening the third generation of sand making machine rotor height can to solve the problem. This revelation if the third generation click into place, heightening the sand making machine rotor height. May change the material ejection state. The third generation system sand machine rotor height is too short, when a certain amount of material into the third generation of sand making machine rotor, the lining plate has been changed to bounce. High speed injection. Due to the use of a long time, the material tray, life of about 300 hours. Analysis of the lining plate before and after the replacement, wear is expected to throw the first position change. The lining plate before the wear more to replace, expected to throw the first wear position has declined, the newly installed points tray, wear position and rise, wear-resisting plate is with the lining plate wear and prolonging life. This shows that the lining plate material will bounce. The material along the upper injection, heightening the third generation sand making machine rotor height become inevitable.
As long as the third generation of sand machine rotor as a whole to balance, on the main bearing box is no negative impact. In accordance with such ideas for the improvement, we will assume the third generation system sand machine rotor structure and cast sprue size drawing paper came out, a third generation system sand machine rotor experiment. Installed to run the result is good. The service life of the main wear parts has been greatly extended. Fully achieved our intended purpose.
