Is it difficult to crush and granulate?

Thanks for your hard work. Crushing and granulating usually requires standing for a long time, which is heavy on the body and easy to cause problems such as backache and backache. The crushing and granulating work needs repeated labor, such as repeatedly handling materials and operating instruments, which will increase the burden on the body and easily lead to muscle fatigue and sports injury. Granulation refers to making all kinds of powder, block, solution or molten raw materials into solid particles with certain shape and strength. It is a process of increasing particle size and an important part of particle technology.
