3A cost effective solution for dewatering and product recovery VARIETY AND VARIABILITY The innovative modular design of the ANDRITZ horizontal vacuum belt ˜lters enables us to o˚er a wide range of ˜lters with e˚ective ˜ltration areas ranging from 6m 2 to 138m 2. This coupled with a wide range of materials of construction enables ANDRITZ to customize solutions to suit any application. The ANDRITZ horizontal vacuum belt ˜lter is able to attain the highest cake washing e˛ciencies when compared to any other ˜ltration technologies, due to plug ˝ow displacement of the wash liquor, resulting in maximized product recovery. The ANDRITZ horizontal vacuum belt ˜lter uses state-of-the-art vacuum ˜ltration technology to o˚er an e˛cient and reliable solid/liquid separation unit that is fully CE certi˜ed for dewatering and washing of slurries. With an installed base of more than 680 horizontal vacuum belt ˜lters throughout the ANDRITZ GROUP, we have encountered some of the toughest dewatering and cake washing challenges in the industry. In fact, ANDRITZ has been working closely with its customers to continuously improve the value and e˛ciency of every machine, without compromising on reliability or availability. ANDRITZ has a wide range of experience in the installation of horizontal vacuum belt ˜lters in a number of industries including, but not limited to: Dewatering applications Ł General tailings Ł Gypsum Ł Phosphate rock Ł Coal fines Ł Magnetite Ł Iron ore Ł LithiumWashing applications Ł Leached materials Ł ZincŁ Copper/cobalt Ł Soda ash Ł Gypsum Ł Flue gas desulfurization (FGD) Ł Pulp washers Ł Potash ANDRITZ horizontal vacuum belt filter

9Intermediate frame with vacuum box lifting device installed Bellows for vacuum box lifting device Innovative features to boost performance even further ANDRITZ has developed a new device for lifting vacuum boxes on horizontal vacuum belt ˜lters Œ the SmartLIFT. Not only does the device make short work of a classically high-risk task, it can also be retro˜tted to any brand or size and reduces downtime for vacuum box maintenance by over 30%. YOUR BENEFITS Ł Transforms a high-risk task into a low-risk task Ł Reduces the downtime required for vacuum box maintenance by 30% Ł Reduces labor input since less manpower is required to lift and lower the vacuum box Ł Reduces the risk of injury during vacuum box maintenance by 50% as the lifting device stabilizes the vacuum box when lifting and lowering Ł Is low-maintenance thanks to the device having no pivoting points WHY DOES A VACUUM BOX NEED A LIFTING DEVICE? Vacuum box maintenance on horizontal vacuum belt ˜lters is an unpleasant, high-risk job. Current methods involve unwieldy hand-operated winches, counterweights, levers, and other manual lifting equipment, all of which are high-labor alternatives that run the risk of personnel injury, while the option of using a pneumatic cylinder can prove prohibitively expensive. HOW DOES IT WORK? The horizontal vacuum belt filter vacuum box is fitted with a SmartLIFT vacuum box lifting device that is situated directly under the vacuum box. A bellow- supported frame runs between guide slides on either side of the main frame vacuum box opening. The support can be adjusted in order to centralize the vacuum box in the horizontal vacuum belt filter. For maintenance purposes, the bellow-supported frame is lifted pneumatically to take the weight of the vacuum box. The retaining system keeping the vacuum box in position can now be removed. Then the bellow(s) is/are simply deflated to lower the vacuum box so maintenance can now be carried out in a safe and stable position. The vacuum box is lifted back into position by inflating the bellow(s).

10Customized solutions to suit your applications and needs ANDRITZ is able to o˚er various options for supporting the rubber carrier belt: Ł Roller deck support system Ł Belt slides Each system has unique advantages that are applied to the filter based on the application requirements and your specific needs. The roller deck support system contains a number of low-friction rollers to support the belt, resulting in minimum drive power Numerous design options are available for the horizontal vacuum belt ˜lter in order to o˚er the optimum dewatering or cake washing solution that ˜ts your needs. One of the options includes the selection of the rubber carrier belt support method in order to minimize friction and increase the lifetime of the rubber carrier belt. requirements. The rollers have internal bearings, which result in minimal maintenance and eliminate the need for a high-pressure blower. This reduces consumption of energy or lubrication water, resulting in lower OPEX costs. The belt slides system is made up of disposable wear belts running on strips that utilize water to minimize friction. While this system eliminates the need for a high-pressure blower, more lubrication water is required. However, there are fewer moving parts so less maintenance effort is required.
