Background technique

A mixer is a machine with a bladed shaft that rotates in a cylinder or a tank to stir and mix various raw materials to make it a mixture or a suitable consistency. There are many types of mixers, including forced mixers, single-shaft mixers, and twin-shaft mixers. This kind of mixer needs to be manned, and the materials to be mixed are put into the mixer at all times, and it does not have the function of continuous stirring, that is, it can only perform the process of filling-stirring-discharging-refilling in a single line. Continuous filling and discharging cannot be achieved.
