Whilst enjoying immense popularity for many years on small horizontal and inclined screens, BMPE has introduced the simple drive arrangement on large horizontal and inclined screens. This single development has resulted in tremendous advantages as far as reduced maintenance, compactness and simplicity are concerned. Besides the simplicity of the drive, many other features have been incorporated to provide a machine which is specifically designed for heavy duty applications, long life, and low operating and maintenance costs, at a competitive price.

The advantages of BMPE Horizontal Vibrating Screens is that use of the following equipment has now been rendered unnecessary:

The inherent simplicity of the drive arrangement ensures the minimum possible maintenance.

Instead of the old type of fabricated screen decks, all STAR TRACE 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.

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 to be replaced, thus reducing costs and downtime.

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.

The illustration shows clearly the simplicity of this device. The swivel half cups automatically align the tensioning bolts to the exact angle to accommodate various wire thicknesses.

The simplicity of the design of these built-in items ensures that feed boxes and discharge lips cannot come loose.

The entire welded fabrication is stress relieved to ensure that all residual welding stresses are removed.

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.

A. Cross members can be utilized as spray pipes. These can be galvanized internally to reduce corrosion.
B. Screens can be mounted on a ‘Rosta’ support system for prolonged life and reduced vibration transmission, particularly on shutdown.
C. Screens can be mounted on isolation beams to remove 80% to 90% of transmitted vibrations.
D. Drain panels can be incorporated in sides or back plates of screens where the feed contains very large volume of water. Screens can be totally enclosed for handling dusty materials and can be fitted with carrying decks (bottom pans) to reduce headroom.
