AUGER CALCULATION AND SCOPE OF APPLICATION

Currently, many types of centrifugal equipment are used in various industries. Among them:continuously operating filter screw centrifuges, pulsating, inertial, vibrationally discharged sludge and settling screw centrifuges. It is the most efficient equipment used in the food and meat industry and provides high-quality separation of liquid heterogeneous systems [1].
Screw devices used in the food industry are divided into augers: conveying and pressing.
The pressing screws are designed to create increased pressure in the product in order to change its physical properties, shape and ratio between the solid and liquid phases.
The special feature of the pressing screws is high pressure: up to 6-20 MPa and low rotation speed: 5-30 rpm.
Transporting screws are provided to move the product. They can additionally perform the functions of dosing and mixing.
They have higher rotational speeds: from 50 to 400 rpm and should not create excessive pressure on the product, as well as not over–pump the transported material.
As a working body, the auger has the following advantages: simplicity of design, versatility, compactness, and low cost.
In research papers, geometric dimensions are considered generically and are taken based on the patterns of the average value. This cannot fully provide an accurate description of the ongoing process. These facts indicate that the separation of liquid heterogeneous systems in centrifugal equipment still requires a large amount of research.
