04 05 Sirocco Air Classifiers offer the most efficient dry-wash solution to remove excess fines from sand or crushed rock The CDE Sirocco produces high quality sand for a range of applications including concrete manufacture. The system is particularly suited to processors without ready access to water. Sirocco air classifiers are most often employed in arid climates where water resources are particularly limited. However they also appeal to producers in more temperate regions who may not want to introduce water to their process for a variety of reasons. Our air classification technology has been proven over 70 years and 3000 worldwide installations to be the most efficient and effective air classification technology available in the world. The Introduction of a Sirocco air classification system allows you to: 1/ Efficient removal of excess fines WITHOUT WATER 5/ Guaranteed results; full lab testing; assured backup Sirocco Applications Construction Specifically for the processing of -6mm material the Sirocco air classification system ensures the most accurate removal of fines. The Sirocco can be used to process: Granite Limestone Gabbro Trap Rock Sand & Gravel Other Industries Many applications in a variety of other industries, including: 2/ Excellent results with natural and crushed sands 3/ World beating efficiency - accurate cut point 4/ Full model range available for capacities of 50-800tph 6/ Small operational footprint with rapid deployment and site set-up 7/ Stand-alone units to integrate with your existing equipment or complete systems Animal Feed Chemicals Fertilizer Food Glass Minerals Pharmaceuticals
06 07 Sirocco Key Benefits Feed Spout Separating Zone Separation efficiency The primary concern with any classification system is the ability to effectively remove fines from a feed stream while also minimising loss of quality sand. Sirocco is proven to be the most efficient system available in this regard. Recovery of material in the 75 micron to 600 micron range is crucial to the production of in-spec sands and Sirocco significantly outperforms other air classification systems within this range. The increased efficiencies offered by Sirocco ensure maximum production of inspec sand from your feed stream resulting in a quick return on your investment. Pendulum enclosed drive mechanism Ensures free, high speed, rotary movement of the fan assembly within the Sirocco unit, optimising airflow. The self supporting drive mechanism eliminates the requirement for an internal support frame which ensures air flow is distributed evenly throughout the unit. The pendular fan assembly design also reduces potential abrasion and maintenance costs as there is no unnecessary framework obstructing the coarse material fall-zone. Minimal wear on selector blades Due to the positioning of the distributor plate which is located under the selector blades, larger particles simply fall directly into the collection chute rather than impacting unnecessarily on the selector blades. As it is the larger particles that will cause the most wear within the system, this design feature ensures that resistance to wear within the Sirocco unit is maximised, thus increasing plant life and reducing ongoing operation and maintenance costs. This also ensures that the selector blades are not fed any more coarse material than necessary, thereby increasing efficiency in their actual role of preventing excess loss of commercial fines. Circulating Fan A range of capacity requirements within a single Sirocco unit Multi-point opening design for distribution of feed material Easily replaceable selector blades Distributing Plate Selector Blades Return Air Vanes Sirocco offers a range of models allowing production from 50 tons per hour to 800 tons per hour from one single unit. This allows you to select the system most appropriate for your production requirements and where capacities over 200 tons per hour are required eliminates the need for investment in additional ancillary equipment such as feed hoppers and feed and stockpile conveyors to feed two independent classification units. Promoting even distribution of material onto the distribution plate before entering the classification chamber. This results in an even distribution of material across the air flow within the Sirocco system, maximising processing efficiency. The Sirocco unit has been designed with ease of maintenance in mind and the individual selector blades can be replaced quickly and easily, minimising plant downtime and maximising production Coarse Cone Fines Cone Coarse Discharge Fines Discharge
Sirocco Key Benefits 09 FEED CONVEYOR MOBILE STOCKPILE CONVEYORS Optimum quantity of selector blades The Sirocco system has up to 4 times more removable selector blades within the unit when compared to other air classification systems, maximising the potential for efficient fines removal. The performance of the selector blades is further enhanced by the presence of a Variable Speed Drive (VSD) which gives excellent cut point control. Unique coarse cone design for minimum wear The unique ribbed design of the coarse cone section within the Sirocco ensures minimal impact of material on steel reducing wear and thus reducing ongoing plant operation and maintenance costs. The coarse cone is also fitted with easily replaceable steel liners to ensure the minimum amount of time is spent on plant maintenance. Superior wear resistance The specification of durable, wear resistant liners throughout the Sirocco unit ensures maximum resistance to abrasion allowing for the efficient processing of abrasive materials. The focus on superior wear resistance within the Sirocco system also ensures lower operation and maintenance costs when compared to other air classification systems. INSTALLATION
Sirocco Key Benefits Modular bolted construction CDE ProMan World Class Project Management Ensure Optimum Efficiency with ServiceMax Benefits of the modular bolted construction over a welded design are two fold: 1. Reduced transport costs as a result of the fact that the unit can be containerised easily. 2. Installation time on site is significantly less than with welded design ensuring your plant is producing in-spec sand products much sooner than would otherwise be the case. Easy, Safe Access for Operation & Maintenance All walkways are fully compliant with European Health and Safety Specifications and offer easy access for operators and maintenance personnel. This minimises time required for maintenance thus maximising the operational time of the plant. Our experience in the design of large turnkey mineral processing projects ensures your project will be designed and delivered to the highest possible standards CDE s ProMan system is proven to deliver highly efficient and productive plants through a process which ensures that lines of communication are clear and everyone involved from both your side and ours knows exactly where the project sits at any given time. This system has been implemented effectively on numerous worldwide projects from the UK and Ireland to India, Middle East, Africa and North America. A dedicated project team is appointed as soon as the project goes live which contains all the major disciplines required to deliver you a truly world class project. Through this process you are allocated a dedicated Single Point Of Contact (SPOC) who is ultimately responsible for the delivery of your project in its entirety. Following installation of your Sirocco system the focus switches to ensuring optimum efficiency is maintained. Through our suite of ServiceMax packages we will continue to work with you to ensure that this is the case. There are a variety of service level packages available and they offer many services including: Your own individual CDE Account Manager Comprehensive Operator Training to ensure the highest levels of health & safety and plant efficiency are maintained. Regular plant audits to highlight improvements in plant operation & maintenance that will lead to a safer, cleaner, more productive site. Recommended Spares Lists detailing plant wear parts that should be held in stock to minimise plant downtime when maintenance work is required. MATERIAL STOCKPILE Fan Blade Our wish and yours is for a project that is delivered on time, on budget and performs to the highest possible standards. ProMan is the methodology that has been proven to consistently deliver this outcome.
