Textile breaker conveyor belts

Application

All conveyor belts Delta and DX-ST can be equipped with the option (if the thickness of the cover is sufficient) of a fabric, steel or aramid breaker ply whose function is to protect the textile fabric of the carcase from ripping or impact. The breaker ply may be inserted in the top cover (1 or 2 breakers) or in both covers if double protection is required. In addition it may be either included in the cover thickness or more of the cover.

Corresponding configurations are called respectively:
• BRK1+0: 1 steel, fabric or aramid breaker, which is always on the top cover.
• BRK1+1: 1 steel, fabric or aramid breaker in the top cover and 1 steel, fabric or aramid breaker in the bottom cover.
• BRK2+0: 2 steel, fabric or aramid breakers in the top cover.

These belts are utilised in applications where resistance to impact is required and there is a risk of ripping due to the character of the material being carried or the possible presence of undesirable sharp objects

Steel Breaker XST-SC

The steel breaker ply has ample capacity to resist tearing. The ply is constructed of steel cables resistant to cutting and tied together by polyamide wires. The resistance of the cable and the spacing of the cables vary according to the resistance required. The steel cables are orientated in the weft direction of the belt.

The steel breaker is denominated for its ultimate tensile strength at the break, in N/mm; in the direction of the steel cables, which relates to the transverse direction of the belt We offer the breaker plies in grades 125,160, 200, 250, 315, 400. BS – 125 is stated to be that the resistance to break in cable direction (it relates to the direction of the weft of the belt) as better than 125 N/mm.

Fabric Breaker XE

Manufactured with fabric plies, they are produced using the same elevated belting systems technology. They provide greater stability than the commonly used EP fabrics (polyester – nylon) by adding to these one or two monofilament fabricsto achieve the rigidity most suitable for the belt’s characteristics.

All XE , SC and XSC belt types are manufactured in the following rubber compound varieties:

N: Normal Quality
G: Oil Resistant Quality.
S: Flame Retardant Quality.
HR: Heat Resistant Quality up to 150ºC

MAXIMUM WIDTH IN STANDARD MANUFACTURING: 2400 mm

We manufacture belts with different covers and widths other than standard ones on request.

Mesh Breaker XE-SC

Manufactured with fabric plies, they are produced using the same XE-SC type technology but differ from this in that their rigidity is achieved by inserting one or two metal cords across the belt.

This type of belt is recommended when the rigidity needed is not satisfied by the XE-SC type. It is particularly indicated for the transportation of large productions and heavy duty applications requiring significant width dimensions.
