7 1 2 Feeding Screening 13 35m³ hopper being feed The integrated 30m³ feed hopper is fitted with a belt feeder to ensure the most efficient transfer of material from the hopper to feed conveyor. The belt width is the same on the belt feeder and transfer conveyor ensuring the smooth flow of sticky material. - Ensures free flow within the system - Ensures efficient plant maintenance - Maximises plant production The grid width of the feed hopper is 5.5m to easily accommodate larger loading shovels. Designed with washing in mind The P2-108 model is designed with their primary function to be as a rinsing screen. There are a number of features of the ProGrade screen range which ensure its performance as the premier rinsing screen on the market: Individually controlled spray bars The water supply to each spray bar can be shut down individually to allow for easy modification to the washing system depending on the specific requirements of the material being processed. Rotating spray bars for ease of access The spray bars on the ProGrade screen rotate allowing easy operator access for replacement of screen media. This reduces plant maintenance time and allows for quick and easy changes to the screen configuration to allow for variations in final product requirements to be easily accommodated. Each spray bar nozzle is also individually adjustable to allow for appropriate positioning relative to the material on the screen deck. Stand alone spray bar assembly The spray bar assembly is isolated from the vibrations of the screenbox through its own independent structure, therefore optimising performance. A safer, cleaner, more productive site Splash prevention over decks and specialist spray bar seals reduce the risk of both material and water loss resulting in a safer, cleaner, more efficient operation High specification bearings and unique bearing protection Market leading SKF bearings are used as standard on the ProGrade screen range and a unique double seal arrangement prevents contamination of the bearings during plant operation. The use of high specification bearings, coupled with the unique bearing seal arrangement: 1. Ensures maximum plant uptime 2. Reduces time and cost of plant maintenance and repair 3. Ensures maximum production from your screening plant Replaceable polyurethane lined feed impact zone This minimises the impact of material on steel and its position also ensures that material is delivered to the very back of the screen, maximising the available screening area. Easily replaceable rubber lining also reduces the time required for plant maintenance therefore increasing plant productivity. Galvanised ProGrade P2-108 screen

8 14 Rosta tensioned drive unit for increased belt life and efficiency As belts are held in constant tension they are not subjected to any shocks as the ProGrade screen rotates resulting in increased plant life and reduced maintenance costs. Easy accommodation of a variety of screen media The screen media on the ProGrade screen range can be changed quickly and easily with no modifications required to the screen box. The ProGrade screen range can accommodate: - Isenmann Polyurethane modular panels - Side tensioned rubber mesh - Side tensioned wire mesh Any combination of these can be used on the ProGrade screen. Revolutionary shaft design The ProGrade range includes a unique hollow shaft design. This high performance shaft has a reduced mass due to its innovative design features. A reduced mass with the same output ensures a significantly lower power requirement. This prolongs bearing life and ensures maximum plant uptime. Bolted, not welded Welded structures induce higher stress levels than bolted structures. Throughout the ProGrade range there is minimal use of welding which significantly reduces stress on the structure therefore increasing plant life. Cast cross member design ProGrade screen The P2-108, consists of a unique, patent-pending case cross member design which minimise mass and the number of welds. Superior wear protection The shaft assembly and all cross members are rubber lined as standard offering increased wear protection and reduced ongoing maintenance requirements. Magnetic polyurethane wear protection is also available on request which is easily replaced ensuring efficient maintenance. Standardisation of spares with EvoScreen dewatering screen range A common set of spares exists ensuring: - Minimum number of different parts need to be held in stock - Reduced time required for operator maintenance training - Reduced time spent on plant maintenance Laminate Design Our P2-108 screen has a patent pending laminate side wall design* which has zero welds. It also has a patent pending cast cross member design** which has also eliminated welding. ProGrade screens are superior screens as they have no welds and this ultimately means a stronger, lighter structure which requires less power. GRP Guarding on all screens New lightweight GRP guards on all CDE screens ensure quicker and safer maintenance and are noncorrosive. * Patents Pending: GB , PCT/EP2013/ ** Patent Pending: GB ProGrade High Pressure Spraybars ProGrade Rinsing Screen

9 3Sand Washing 17 Split screen on EvoWash EvoWash Stockpiling Washed Sand To ensure maximum efficiency the integrates the latest EvoWash sand washing technology. Our EvoWash plants have developed a reputation for ensuring efficiencies are maximised. With many installations throughout the world with the major construction materials producers, our EvoWash systems have been proven to deliver high quality washed sand to the global construction market. This unit includes: 1. Hydrocyclone 2. Dewatering Screen 3. Sump 4. Slurry Pump The modular design of the CDE EvoWash sand washing plant facilitates highly accurate separation of silts and clays from the final washed sand product. Silt cut points of 40 micron and below can be achieved through the introduction of one of our fines recovery sand washing systems. These washing systems are employed in the production of specialist sands such as silica sand, golf sand and filter sand for use in municipal waste water treatment. Throughout the integrated EvoWash sand washing plant there are examples of design features and innovations which have established this system as the number one choice on the global market. Some of these features are explained in more detail here: Modular Isenmann Polyurethane non-bolted screen media for: 1. Maximum dewatering of your sand product 2. Maximum wear resistance 3. Efficient grading of your sand product 4. Ease of maintenance - Replaceable polyurethane side wall protection on the EvoWash screen minimises material on steel contact, reducing wear and increasing the working life of the machine. - Rubber lined pipework ensures maximum wear resistance to minimise lifetime cost of ownership. - The position and size of the rubber lined feedbox minimises the impact of material directly onto the screen deck, increasing operational life. - The positioning of the rubber lined feedbox allows for cyclone underflow to be discharged across the full width of the dewatering screen maximising the screen area and ensuring high efficiency dewatering. - Integrated Centrifugal slurry pump as standard. - Centrifugal slurry pump mounted at rear of the EvoWash ensuring safe and easy access to the pump & motor for maintenance. Increasing the safety of plant operation and reducing maintenance time. - Mining grade pipework is used to connect the slurry pump to the hydrocyclone ensuring maximum wear resistance.

10 18 - The EvoWash uses CDE hydrocyclone technology, developed through our experience in the delivery of more sand washing plants than any other global supplier. - The use of marshmallow screen mounts ensures 10-15% more energy is transferred to the dewatering screen. Increasing the dewatering achieved on the screen and reducing oscillating variable stress. - All galvanised walkways, handrails and access stairs are compliant with European Health and Safety specifications. - The cyclones on the integrated EvoWash sand washing plant discharge directly to the next phase of processing rather than returning this material to the sand plant sump. The EvoWash eliminates fines loss fines are lost when the overflow is returned to the sump as this causes the sump to overflow, taking good quality sand with it. - The EvoWash includes our VibroSync A Screen which has a unique motor assembly ensuring constant linear motion is maintained in the driving plane. - Splash cover on the EvoWash screen ensures water is retained within the circuit rather than splashing around the site. This leads to a safer, cleaner site. - Dewatered sand is discharged from the EvoWash at typically 12% moisture content ready for market straight from the belts. - Cyclone overflow containing waste material is discharged at the highest point of the plant which facilitates easy delivery to the settling ponds or water treatment phase and eliminates the requirement for secondary pumping.

There are many varying grades of polyurethane with a huge variance in performance levels. Isenmann is the world leader in the provision of polyurethane screen media and it is for this reason that we have chosen them to provide the screen media on our EvoWash plant. Isenmann is part of the Steinhaus group who developed the first polyurethane screen in 1970 for application in sand and gravel screening. This innovation was a response to industry concerns over the wear life of traditional wire mesh. Following the successful introduction of this first polyurethane screen the company went on to introduce the first modular polyurethane system in Today, Isenmann composite polyurethane screening panels lead the industry in resistance to abrasion, corrosion and wear. Each of the Isenmann systems are engineered to offer operators the lowest possible screening cost per ton. Each product offered by Isenmann is built around their 3-point guarantee: 1. To screen efficiently 2. To produce properly graded material 3. To ensure cost effective service life There are a variety of production techniques and processes that ensure Isenmann polyurethane screen media is the best that the industry has to offer. - Isenmann offer more proprietary polyurethane types than any other manufacturer to ensure maximum impact resistance and excellent wear properties. - The use of high precision two headed milling machines during production guarantees every screen panel will install quickly and tightly thereby optimising performance to ensure long life and minimal plant downtime. - Aperture, base height and material is tested on every screen produced by Isenmann. Using durometers, Isenmanns Quality Control Technicians also ensure proper screen hardness before your panels leave the plant. - An aggressive re-investment policy assures you of the most technically advanced equipment, the highest quality control, efficiency and productivity.
