Centrifuge and screw machine
Thread Content
Screw machines have many advantages, and it has become a trend to replace reciprocating compressors (medium and low pressure). There are few opinions on comparison with centrifuges, I hope everyone can discuss it.
Centrifuge and screw machine The centrifuge has large flow rate and high efficiency. The screw machine is a volumetric type and has accurate measurement, but its flow rate is limited and its efficiency is low. Not suitable for conveying large flow media.
Obviously, the centrifugal conveying flow rate is large, and the fundamental difference
These are two different types of equipment. The centrifuge is a separation equipment and the screw machine is a fluid conveying equipment. They are not comparable!
If you want to compare, it should be compared with a centrifuge and a screw extruder. It is estimated that the screw machine mentioned by lz is used in different situations. The feed concentration of the former cannot be too high (in theory, it must have flowability). It accelerates gravity precipitation through high-speed rotation to separate components of different specific gravity in the material.； The feed concentration of the latter cannot be too low, and the liquid phase is extruded through a low-speed variable pitch method. It is especially suitable for separation of raw materials with combustibles as the medium and high concentration (such as xanthan gum production), and is also used frequently in feces treatment.
