Screen/Scroll centrifuge is a filtering or screen centrifuge which is also known as worm screen or conveyor discharge centrifuge. This centrifuge was first introduced in the midst of 19th century. After developing new technologies over the decades, it is now one of the widely used processes in many industries for the separation of crystalline, granular or fibrous materials from a solid-liquid ...

Since the late 1980s, screen bowl centrifuge technology has been widely applied in coal preparation for recovery and dewatering of fine and ultra-fine coal. Screen bowls are efficient and cost effective and, to a large extent, have replaced vacuum filters for recovery of these size fractions. Figure 1: On-site testing with the Sub325 centrifuge.

There is a variety of equipment in use today to dewater fine coal. Fine coal in this instance is considered to be below 0.589 mm (-28 mesh). This equipment includes the screen-bowl centrifuge, disk filter, horizontal belt filter, and drum filter. The most commonly used today, in the eastern U.S., is the screen-bowl centrifuge followed by the

The 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.

The different techniques of dewatering fine coal are illustrated in Fig. 6. Out of the different dewatering techniques, the centrifuge offers the highest amount of water removal. Screen bowl centrifuge is widely used for fine coal dewatering due to its relative low cost as well as ease of operation and maintenance.

Testing was conducted on both high-g force solid-bowl and screen-bowl centrifuges for dewatering and reconstitution of fine-clean-coal slurry at 300 Ib/h (136 kg/hr) in PETC7's Coal Preparation Process Research Facility. In the GranuFlow Process, fine-clean-coal slurry was treated with a bitumen emulsion before dewatering in both centrifuges.

Screen bowl centrifugation process is widely used for fine coal dewatering due to its relatively low cost, high capacity of providing low-moisture content product as well as relative ease of operation and maintenance. However, screen bowl centrifuge tends to lose a significant amount of ultrafine clean coal to the main effluent and screen-drain streams.

Numerous dewatering techniques exist, such as vibrating basket centrifuges, scroll-type centrifuges, screen bowl centrifuges, and solid bowl centrifuges as well as belt-press filters, high-pressure disk filters, and membrane filter presses. All are currently employed in the coal industry .

The solid bowl and screen bowl centrifuge both are effective in dewatering of fine coal as shown in Figure 1. The screen bowl centrifuge even though more effective in providing a low moisture product, loses a significant amount of fine size coal in the effluent.
