How to Clean out the Waste inside the Sand Making Machine

April 08, 2016

After a long-time operation of the sand making machine, there must be some waste inside it. The accumulation of the waste will increase the load and the friction of the sand making machine itself, which will cause that the sand making machine has to spend much more energy on these useless tasks. If it has not been cleaned for a so long time, the machine will be damaged. Therefore, in order to guarantee the safety of the parts of the sand making machine and to increase its working efficiency, the waste inside the sand making machine should be cleaned out usually. In general, the waste should be cleaned out at the end of the whole-day operation, which will not influence the advance of the operation. It can also be cleaned when the sand making machine is not in the operation.

Generally, the pickling and alkali-washing methods are adopted to clean the equipment. The so-called pickling method is that hydrochloric acid solution with 20% solute is splashed into the dirty part of the sand making machine, and, after about 10 minutes, it can be flushed with water. There may be some danger with this method due to the property of hydrochloric acid. The density of hydrochloric acid solution should be adjusted. While the solute density of hydrochloric acid solution is being adjusted, it should be noticed to constantly pour hydrochloric acid solution into water and to stir it constantly. In the adjustment process, you mustn’t pour water into hydrochloric acid solution because it will bring much risk, which means that in this way hydrochloric acid may splash up onto the operator and hurt him. It is also bad for the adjustment of the density.
