Thickeners Brochure

Robust, reliable and efficient is the best way to describe the Roymec Technologies range of Thickeners, exactly what any operating plant needs.Thickener units are available up to 75m diameter with a range of sidewall and centre pier mounted bridge designs, electric and hydraulic drives and fully integrated lift and automated control system.THICKENERS Excellence in process engineering from concept to commissioning www.roytecsa.comThe Roymec range of thickener units are designed to operate under the most arduous plant conditions, and include: Conventional,High Rate,High Density / Pseudo-Paste, Deep cone (raked and unraked), Clarifiers, andUnderground Settlers.Roymec equipment is designed for maximum availability and minimum downtime to keep your process in operation. Roymec have operating equipment reference installations on five continents in 25 countries.Raking drives & mechanisms are supported either by a full/half span bridge arrangement. For larger diameter units, the mechanisms can be supported off a centrally located column. Drive units are either electric or hydraulic, and include a full regime of instrumentation to ensure drive train protection and plant safety.The principle behind our drive train design is for all gears & bearings to have an operating life well in excess of 100,000 hrs.www.roytecsa.comRoymec Technologies (Pty) Ltd. 10 Saddle Drive, Woodmead Office Park, Cnr.

All rights reserved.RAKE DRIVES & RAKING MECHANISMSThe Roymec feedwell is designed for optimum conditioning of the feed stream and controlled reduction in the incoming feed velocity to ensure maximum flocculated particle size is achieved. Our designs ensure that both turbulence and air entrainment are avoided. Optimum thickener operation is dependent on several factors one of which being the conditioning of the feed stream to ensure ideal flocculation and thereby particle settlement. Frequently this requires dilution of the feed slurry for which Roymec Technologies has developed a simple yet effective self regulating feed dilution system. FEEDWELLA fully instrumented and integrated control systems allowing plant feed-back for optimum operation, comprises: CONTROLRake torque level monitoringAutomatic rake lifting and loweringDrive temperature and oil level measurementMud bed level indication Feed density & flow monitoringUnderflow density & flow monitoringOverflow turbidity measurementBed pressure measurement Feedwell settling rate monitoringFlocculant dosing rate control.Visual and audible alarming We offer turnkey project delivery from design through to on-site installation, commissioning and optimisation. Specialised solutions for ease of on-site services include: TURNKEY SOLUTIONS Full workshop assembly and testing.Bolted tank construction, for ease of remote site construction.The option of the inclusion of flocculant/reagent and feed conditioning systems. 2010-05-10ThickenerFrontV1 2 FINAL.pdf 2010-05-12ThickenerBackV1 6.pdf
