The FLEXOCORD® standard range is shown in the table. It is based on DIN 22131 as well as on European standard EN ISO 15236, type A1. Please contact us for enquiries about belt types according to the EN types A2, for belts wider than 2400 mm, or other types that differ from Metso's standard. Metso can supply most existing belt types following different international standards. * The belt weight is for the indicated minimum cover thickness. For each additional mm of cover thickness add 1,1 kg/m2. Conveyor Solutions

The most important factor for the selection of the type of rubber quality is the nature of the conveyed material: lump size, shape, hardness, density, temperature or oil/chemical content. Operating conditions, such as ambient temperatures, radiation or safety requirements also play a role in choosing the correct cover. Metso supplies rubber grades according to a wide range of inter-national standards. Some standard cover grades are listed in the table below. All qualities are resistant against ozone, UV radiation, ageing and are antistatic according to ISO 284. Please consult us for...

The recommended pulley diameters depend on the steelcord diameter, the actual belt tension and the pulley deflection angle. The pulleys in a belt conveyor system are divided into groups according to their position and function, see illustration: Strength utilization in % = 105 x S x T / (B x kN) S Safety factor (6,7 to 8 for Steelcord Belts) B Belt width in mm T Local belt tension in kN kN Belt rating (nominal strength) in N/mm The table below indicates the minimum pulley diameters for steelcord belts depending on the belt rating, pulley group and strength utilization. Group C pulleys:...

FLEXOCORD® Steelcord Conveyor Belts are spliced by hot-vulcanization according to DIN standard. The splice length and number of steps depend on the belt rating. The standard splice is diagonal (approx. 17°), but rectangular splices are also possible. The pictures below illustrate the splice designs. Particular attention must be paid to the splicing procedure. The method, conditions and the splicing kit have a great influence on the quality of the splice. For exact splicing instructions please contact Metso. It is strongly recommended to use splicing materials approved by the supplier. B...

A reliable way to calculate minimum transition lengths (distance between tail/discharge pulley and first/last troug-hing idler) is to use the factors given in the table. The factors depend on the troughing angle and arrangement and must be multiplied by the belt width. If the pulley is elevated with respect to the level of the center idler roll, the transition length can be decreased. Usually the elevation (hp) is one third of the total troughing height (h). Travel of take-up pulley Low elongation is one of the characteristics of FLEXOCORD® Steelcord Conveyor Belts. The travel of the...
