Tailings dewatering press (TDP)
Open the catalog to page 1FLSmidth's experience with belt press equipment dates back to 1979 with its EIMCO® branded belt presses that pioneered the technology. With a long and successful track record in tails management, FLSmidth has taken this proven dewatering technology to the next level. TDP Advantages 2. Vertical S-Roll configuration 3. Elimination of cake re-wetting 5. Rack and pinion belt tensioning 6. Lower operating costs Belt Press Applications • Mining • Quarrying • Industrial minerals • Chemical production Why FLSmidth? FLSmidth's unparalleled expertise with multiple equipment types in a...
Open the catalog to page 23. Gravity drainage zone 5. Pressure zone - "S" wrap section 6. Perforated first roll - double filtration 7. 2nd roll - double filtration 9. Belt tension system 10. Belt aligning system 11. Rack & pinion - true belt alignment The TDP design offers several distinct operation zones that are applied based on the changing characteristics of the feed material as it passes through the continuous machine. 1. Pretreatment zone - inclined solids conditioning zone, flocculation with cationic and anionic flocculants as needed 2. Feedbox - distributes the feed evenly over the width of the gravity...
Open the catalog to page 3Advantages of the TDP Maximum cake dryness with vertical S-roll design Traditional horizontal S-roll design New vertical TDP S-roll design Rewetting zone Traditional roll patterns run horizontally. This leads to pooling between the rolls resulting in rewetting of the belts. In order to avoid these rewetting issues the TDP has been configured in a vertical S-roll configuration. The belt travels upwards and each roll’s filtrate runs into its own drip tray thus avoiding any pooling or rewetting, this produces a drier cake than the traditional horizontal design. Increased safety with low...
Open the catalog to page 4Optimized roll designs for dual filtration Perforated bottom roll and chevron grooved roll Perforated bottom roll Rather than use a solid roll on the first S-roll (S1), we have opted for a perforated roll that allows for dual filtration while avoiding pooling and rewetting. The perforations allow water to be removed through both belts as it drains into the drip tray below. Chevron grooved roll Just like tire treads pump water away from the center of the tire on a wet road, the chevron grooved roll pumps water away from the center of the cloth and off the edges to allow for dual filtration...
Open the catalog to page 5With a design that can be factory assembled and delivered in one piece, the frame provides a rigid structure that will withstand maximum anticipated stresses and provide the best geometry for cloth tracking, which will extend cloth life. All support bearings are self-aligning, anti-friction, with TRIDENT® seals with triple-lip nitrile seals, with L-10 life that exceeds industry accepted standards, and are easily accessible. Belt tensioning is by a pneumatic cylinder with a rack and pinion system that ensures equal travel of the belt from side to side thus eliminating belt bias. Controls...
Open the catalog to page 6Testing, service & maintenance FLSmidth equipment and system designs are continuously improved using the latest available process and design technologies, combined with a detailed understanding of specific process requirements which are supported by database, bench, and pilot scale testing. We can provide on-site testing with a bench scale testing apparatus which is calibrated to the pressure profile of the TDP to profile accurate scale-up design information. This on-site testing capability is backed by regional FLSmidth facilities, as well as the global minerals testing and development...
Open the catalog to page 7Manufacturing A global procurement strategy allows FLSmidth to source equipment and materials competitively, thus creating more opportunities for reduction of cost and optimization of delivery schedules. No other belt press manufacturer has as much experience, competency, and capacity as FLSmidth in providing total one source solutions in minerals processing globally. One Source The FLSmidth Tailings Dewatering Press can be supplied as a standalone dewatering filter or as part of a complete tails dewatering system which may include slurry thickening, polymer storage and mixing,...
