How To Solve The Small Amount Of Sand Produced By The Sand Mixer?

              Resin sand mixer is one of the important equipment in foundries. The performance of the machine directly affects the quality of castings. Therefore, it is necessary to master the maintenance skills of the sand mixer in order to accurately and quickly judge and deal with equipment failures. Repair the equipment in time. What should I do if the sand output of the sand mixer is small during use? Let me tell you how to solve the small amount of sand produced by the sand mixer. Today, the editor of Qingdao Wozhou Machinery will give you an analysis of the common failure types of resin sand mixers and summarize the failure judgment methods for the reference of enterprise maintenance workers and technicians.

　　 Stable and reliable sand volume is an important performance index of sand mixer. The sequence of sand output of the sand mixer is: sand gate-human arm conveying-small arm mixing-quicksand. The sand volume of the sand mixer is unstable, and the fault can be judged according to the sand production sequence:

1) Check whether there is sand in the sand warehouse. A material level alarm device is installed on the sand library. If the sand storage volume of the sand library is lower than the material level installation position, the sand shortage alarm lamp on the main electric control cabinet panel will give an alarm.

　　 2) Check whether the sand gate at the bottom of the sand storehouse is worn. The sand gate will wear out after being used for a long time. If it cannot be checked regularly, the amount of sand will increase.

　　3) The cutter head of the sand mixer is severely worn. Adjust the height of the severely worn cutter head or replace it again. The angle of the cutter head must be inspected and adjusted every day. Generally, the angle between the cutter head and the stirrer shaft is 45%; in addition, the gap between the cutter head and the stirrer shell is also very important. The best gap is 3~4mm.

　　4) If the mixing cage of the sand mixer has not been cleaned for a long time, the residual sand will agglomerate, resulting in a smaller sand mixing space and a small amount of sand.

　　5) It is necessary to calibrate the sand volume of the sand mixer more than twice a month to verify whether the quicksand of the sand mixer is normal.

　　 The above is the method to improve the production efficiency of resin sand equipment organized by Qingdao Wozhou Machinery for you. This is our conclusion based on years of experience. We hope to increase the profit of the foundry enterprise and reduce the production cost.
