Cement pneumatic conveying

Cement can be conveyed in different ways. It can be transported using either pressure (positive) conveying or vacuum (negative) conveying. The former uses compressed air at the start of the system to push the cement through the piping while it is "sucked" toward its destination when using the latter. Whether you need to use the positive or ...
