What kind of pump is suitable for transporting wood chips?
Thread Content
Medium: wood chips (dimensions of wood chips: length 15–30 mm, width 15–25 mm, thickness 3–6 mm). Concentration: 10%~15%. What type of pump is suitable for use as a transfer pump?

It’s amazing that these wood chips can still be transported, and there’s also a concern regarding concentration – it’s clearly a sophisticated technology. Well, let’s talk about the specific process: in what form do the wood chips exist? Are they mixed with other materials, or are they pure wood chips? If they’re part of a mixture, screw conveyors can be used, but height control isn’t guaranteed; for other cases, elevators are used. As for whether centrifugal pumps can be used for such large wood chips, there are no existing examples yet, as this type of material tends to cause blockages and jams.
The purpose of this pump is to transport from low pressure (from the atmospheric-pressure impregnation tower) to high pressure (in the pressure cooker), with the wood chips existing in a suspended state.
I don’t understand whether a finer grinding of the wood chips would result in a better extraction effect.
From a processing perspective, there is no need for crushing; instead, slicing followed by pre-impregnation and cooking is sufficient.
