CMI’s Screen-Scroll Centrifuge is capable of reaching high capacities without restrictions or loss of feed velocity due to its large feed opening.
All CMI Model EBR Centrifuge parts, with the exception of the rotating process components, with those of the Model EBW Centrifuges, which allows for reduced parts inventories.
Long Life Parts Package® – Every CMI Model EBR Screen-Scroll Centrifuge includes the Long Life Parts Package as standard equipment, which significantly reduces the cost-per-ton of processed solids.
Direct Oil Lubrication –Internal bearings are continuously lubricated by a separately driven gear pump. With constant filtering and a low pressure-sensing switch, positive protection is afforded to the bearings and gear unit.
High Strength Gearing – The CMI Model EBR Screen-Scroll Centrifuge features a drive unit and gear box to maintain the differential speed required between the screen and the scroll. The package is a sealed unit that can be replaced without exposing internal parts to the dirty atmosphere that exists at most machine installations.
Due to its unique vertical design, the screen/basket assembly is the first rotating component to remove during maintenance. CMI’s cost effective screen design often outlasts competitive units costing two to three times as much.
In addition, belts on the CMI Model EBR Screen-Scroll Centrifuge can be changed by removing two bolts and one oil line from the bottom without any disassembly of the top parts.
Designed for the dewatering of small particles between ½” and 1 mm, the CMI Model EBR Screen-Scroll Centrifuge demonstrates the latest in centrifugal dewatering technology. In addition to being used for coal preparation, CMI’s screen-scroll centrifuges are also being utilized in the dewatering of potash, gilsonite, in salt processes and in dewatering various sands.
The CMI Model EBR Screen-Scroll Centrifuge is available in 36”, 40” 42” and 48” configurations.

Material Flow - EBR Screen-Scroll Centrifuge
Material fed into the machine is accelerated by the rotating parts contacted. Solids are retained on the screen surface, while centrifugal force slings free liquids through the screen openings. Movement of solids across the screen surface is controlled by flights, which move relative to the screen.
Solids discharged from the screen fall by gravity, through the machine's bottom opening. Liquids that have passed through the screen are collected and discharged through two effluent outlets.
Long Life Parts Package®
Screen-Scroll Centrifuges have been revolutionized through the introduction of the Long Life Parts Package. Replacing the "standard" rotating components in Model EBR and EBW Screen-Scroll Centrifuges with an integrated package of components, the CMI Long Life Parts Package provides substantial operating cost-reductions, while also improving overall performance. The Long Life Parts Package was designed to alter the material flow within the centrifuge in order to address the serious sliding abrasion that contributes substantially to the overall operating and maintenance costs of screen-scroll centrifuges. By utilizing a patented "material on material" concept to accelerate material to centrifugal speed, dewatering can be more effective while improving the component life of nearly all contacted wear items.
Cost savings can be realized from both the improved life of Long Life Parts Package components, and from the increased machine availability that the Long Life Parts Package provides. Typical first-year savings can be as much as 35-40% over standard rotating components. The Long Life Parts Package is designed to reduce abrasive wear within CMI Screen-Scroll Centrifuges and results in significantly reduced operating costs. All new and remanufactured CMI Model EBR and Model EBW Screen-Scroll Centrifuges are equipped with the Long Life Parts Package as "standard configuration".
In addition, Long Life Parts Package Conversion Kits are available to convert the 36" Screen-Scroll Centrifuges to 40" machines, and 42" Screen-Scroll Centrifuges to 48" machines. Through conversion, the same base machine can be used to accept increased feed slurry or, if increased capacity is not a concern, can offer product moisture reduction through increased screen open-area. These benefits are in addition to the proven cost-savings realized by Long Life Parts Package customers. These two conversion kits also provide a single basket design that can accept either perforated plate or profile-wire screen configurations, allowing for greater flexibility in meeting demands of specific applications.
