Read MoreThe SIEBTECHNIK TEMA CONTHICK screen bowl decanter is a hybrid centrifuge consisting of a solid bowl in the product feed zone and a screen bowl fitted downstream. Solid materials are separated by sedimentation in the solid bowl and thickened. The product can then be washed and dewatered up to the mechanically separable dewatering limit.
Read MoreTURBOSCREEN screen bowl decanter centrifuge Customized according to specific application. On standard solid bowl screen centrifuges the screening section is connected to the small diameter of the solid bowl cone and the diameter of the screen is identical. This design has the disadvantage of a low volume in the dewatering section of the centrifuge.
