The extrusion granulator used by our company is from JSW. . . The cooling water for sections 4 and 7 of the cylinder is blocked. . . It’s completely blocked; I’m trying to clear it, but there’s no good way to do it. . . . I’m asking the experts here for any good suggestions.

The cooling water for the cylinder is usually desalinated water, so there shouldn’t be much dirt in it – how could it get clogged like this?

This cooling water is all deionized water, so it shouldn’t get clogged; how is it that there’s no flow at all? If there is flow, acid cleaning could be tried.

Try chemical cleaning. Are your demineralized water parameters fine?
