Dewatering Screen

We bring forth the best Dewatering Screen. Dewatering Screen is designed using stainless steel metal for heavy-duty performance. Dewatering Screen integrates Screen and Vibratory Motor. We have made Dewatering Screen available in different models to cater diverse demands of the clients.
Construction

• Screen : It integrates modular polyurethane or stainless steel panels. Screen has trapezial cross section mesh openings that revent obstruction and blocking.
• Vibratory Motor : Its robust and heavy-duty units are insulated against the ingress of dust and water. It has IP 55 protection, which ensures operations of units in wet conditions, such as in washing and dewatering applications.

Operation
During material dewatering, water is filtered through the mesh as a result of vibration while the material is conveyed toward the point of discharge. The filtered water carries solid particles whose size is slightly smaller than the mesh openings, which must be recovered by means of hydrocycloning and incorporated to final product in the discharge area. The level of moisture that can be obtained in the end product is between 10% and 15%, depending on its nature, particle size distribution and water content in the feed materials.
When the two vibrating motor that installed vertically on the sieve relatively rotate, the eccentric block of two vibrating motors produce rated excitation force. The horizontal excitation force cancel each other out, the vertical excitation force is transported to the whole screen surface through the body mass vibration. Materials do the jumping movement on the screen surface to the outlet because of the vertical excitation force. Materials which smaller than the mesh drop into the lower layer and discharge from the outlet after doing the jumping movement. Because of the reasonable screen, after vibrating screen, we can get materials of different concentration particle sizes and done the rating work of materials.
Features

• Individually Replaceable Cross Members : Instead of the old type of fabricated screen decks, all STARTRACE screens now incorporate a unique bolted deck arrangement. This means that when wear occurs and deck replacement becomes necessary, only the worn sections are replaced. This is far easier than stripping the entire screen and handling large, heavy fabricated frames. When polyurethane panels are to be fitted to screens up to and including 1 200 mm in width, the panels are located directly into the individually replaceable cross members. The panel and cross member, by direct impingement of the material being screened, is prevented. On larger screens, the cross members can be rubber lined for protection.
• Angle Runner System for polyurethane Modular Units : One of the most common complaints with conventional frames for polyurethane panels is the premature wear of the pinholes in the deck, with resultant loosening of the panels. On screens over 1200 mm in width, easily replaceable angle runners are provided to secure the polyurethane panels. With wear, only those runners affected need be replaced, thus reducing costs and downtime.
• Flat Bar Runner System for Woven Wire Decks : As in the angle runner system for polyurethane decks, the flat bar stringers are bolted to the cross members, resulting in an easy to maintain deck arrangement.
• Automatic Alignment of Tensioning Bolts for side Tensioned woven wire Decks : The illustration show clearly the simplicity of this device. The swivel half cups automatically align the tensing bolts to the exact angle to accommodate various wire thicknesses
• Built-in, Lined Feed Boxes and Discharge Lips : The simplicity of the design of these built in items ensures that feed boxes and discharge lips cannot come loose
• Stress Relieving : The entire welded fabrication is stress relieved to ensure that all residual welding stresses are removed
• Screening Surface : The screens can be fitted with a variety of screening surfaces, such as punched plate, tensioned woven wire, polyurethane or rubber mats, plug-in polyurethane panels, or wedge wire panels.

Benefits

• Consistently dewatered product output - typically less than 14% mositure content ensures product is ready for market straight from the belts.
• Supplied with modular Polyurethane non-bolted panels as standard for maximum wear resistance and ease of maintenance.
• Fully rubber lined discharge chutes for maximum wear resistance.
• Marshmallow screen mounts to harness vibration on the screen and minimise its transfer to the supporting structure thus minimising stress.
• Tow high frequency 3.6kw vibrating motors fitted as standard (2no 9kw motors standard on A-series) to ensure maximum dewatering.
• Unique goal post design above vibrating motors provides additional plant safety by removing cabling from the motors and any other moving parts of the plant.
