Mixer direction of development so far, time Mixer application in foundry has reached thirty years or so, the type of mixer, the structure has been basically finalized, quality is more stable. Judging from the domestic development direction, predominantly in the following characteristics. One large. The more mature domestic mostly 5t / h ~ 12t / h of Mixer twenty-first century a large mixer (20t / h or more) are mostly imported equipment. At present, development and production of a small number of manufacturers of such equipment, sand production equipment business, sales prospects are relatively good. Second, smart and automation. Electrical systems performance improvement, the mechanical structure more simple, a gate height achieved by the lifting arm, increased its sandbox height variation greater ability to adapt to circumstances. 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 used for slightly modified organic ester water glass self-hardening sand production. Fourth, no head and tail of sand. Vertical Mixer usually have this feature, horizontal mixer by structural or electrical improvements can also have this feature. Fifth, sand outlet exhaust port is provided. Can reduce the free formaldehyde and other harmful gases in the exhaust at the workplace, improve working environment modeling work. Reduce the impact, the structure is more simple. 1 sand grind safety procedures, work carefully before confirmation roller is intact, if the fault promptly notify the service for repairs. 2, the work ought to wear labor insurance protective equipment. 3, sand grind before turning sand equipment, checking gear parts are compliant, bearing anchor bolts and screws to fasten the various parts of a reliable connection, found only after boot problems in time. 4, electrical switches and power is in compliance with the requirements found in time to find out gates or open an electrician for replacement service. 5, in the first boot, the principle of the use of fillers, not packing excessive overload. 6, pay attention to the motor, the functioning of each bearing gear, such as abnormal immediately stop inspection process. 7, sand grind size gear every day, plus the 2nd calcium base oil again. 8, each use to clean up sand mill, sand mill prohibited from entering the interior cleaning, Shandong Mixer equipment, maintaining equipment and the environment clean. 9, the cleaning process must supply the total gate closed semi-automatic molding line production process, the performance of sand have a decisive influence on the quality of casting, sand casting performance to ensure quality control is an important means of technology. Reasonable choice of raw sand, bentonite, coal and other raw materials, sand control the moisture, compaction rate, air permeability, wet compressive strength, bentonite clay content and effective content, volatile matter, ignition loss and sand temperature, sand water are the key performance sand automatic molding line control. Sand should determine the appropriate performance indicators, control parameters and control methods, strict sand mixed system of processes, to ensure the normal operation of automatic molding line, give full play to the advantages of automatic molding production lines. Stable performance of the sand, it is to get a good yield of casting equipment manufacturers to provide a guarantee Mixer | Qingdao Heng (certified) | Mixer equipment provided by the Qingdao Heng Machinery Co.
