Mixer's development direction so far, time Mixer application in foundry type reached about three decades sand resin sand equipment manufacturers, Mixer, the structure has been the basic shape, the quality is relatively stable. Judging from the domestic development direction, predominantly in the following features. The first large-scale. More mature domestic mostly 5t / h ~ 12t / h of Mixer Mixer equipment, twenty-first century before large mixer (20t / h or more) are mostly imported equipment. Currently there are few manufacturers of such equipment development and production, sales prospects are more favorable. Second, smart and automation. Electrical system performance improvement clay sand mixer equipment company, the mechanical structure is more compact, spout height can be achieved through the lift arm to improve the height of the sand box large changes in circumstances adaptability. Third, the system can be mixed on the back of sand, can be adapted to multi-process production requirements. If the original self-hardening resin sand for continuous mixer can be slightly modified for the water glass, organic esters Sand production. Fourth, no head and tail of sand. Vertical Mixer usually have this feature, horizontal mixer by improving the structure or electrical can also have this feature. Five is located outlet exhaust port sand. Can reduce formaldehyde and other harmful gases emissions at work, improving work environment modeling work. Reduce the impact, the structure is more simple. How to determine the most appropriate Sand Mixer time? Can be used in the production process, in accordance with the provisions of mixer, mixed sand, mixed with sand to finish the wet sample measured compressive strength. And then extend the time DRUM Sand Mixer of 0.5 ~ 1 min (rotor-type mixer to extend from 10 to 20 seconds). When you add a small amount of water sand to keep the sand compaction rate is essentially the same, again measured sand wet compressive strength, intensity values ??will have different degrees of increase. So each time and continue to extend the sand measured strength. Intensity rises gradually become gentle, until the rise in intensity, which reached the "peak intensity" so far. Intensity due to the proximity of the raised plateau region is extremely slow, generally considered the molding sand reaches a peak intensity of about 80 to 90% is the most suitable for use in the production of strength. To achieve the most appropriate time to use the strength of sand should be the right time to make this kind of mixed sand, plants can process accordingly corrected time requirements specified resin sand sand sand equipment, sand equipment Tai'an, Qingdao, Qingdao Heng Heng Machinery Limited.
