The Mine Wearlok® II belting series extends the desirability of the straight-warp premium stretch concept to the higher tension ratings by using two plies of straight-warp carcass. Mine Wearlok® II represents the state of the art in minimum ply conveyor belting.

BALANCED COVERS

Balanced cover ratios are extremely important in conveyor belt manufacturing. conveyor belt cupping, curling and tracking problems are greatly reduced with a well balanced conveyor belt. Mine Wearlok® takes this concept a step further and gives you the piece of mind that not only do you have a well balanced conveyor belt, but a product that will stand up to the most stringent applications.

Mine Wearlok® I - Mine Wearlok® I is manufactured with pulley cover gauge at least one half of the carry cover gauge. The minimum pulley cover gauge is 3/32" for Mine Wearlok® I belting.

Example:
3/32" x 3/32", 1/8" x 3/32", 3/16" x 3/32", 1/4" x 1/8"

Mine Wearlok® II - Mine Wearlok® II is manufactured with the pulley cover at least one third of the carry cover gauge. The minimum pulley cover is 3/32" for Mine Wearlok® II belting.

Example:
3/16" x 3/32", 1/4" x 3/32", 3/8" x 1/8"

MINE WEARLOK® CARCASS

Mine Wearlok® utilizes a Georgia Duck-developed straight-warp, all-synthetic carcass. This development is a total departure from the traditional plied belt concept and steel cord/rubber belt construction, making it tougher and stronger than conventional high-tension belt constructions. Strength is concentrated length-wise and cross-wise in parallel planes of heavyweight, high-strength straight yarns, locked together by a unique binder system. The synthetic fibers yield a higher unit strength and exceptional resistance to abrasion, cutting and snagging. Mine Wearlok® provides high load-carrying capacity, extended life, and very low stretch.

The straight-warp carcass design yields a carcass construction wherein the basic lengthwise (warp) yarns are essentially uncrimped. These are the main load carrying tension yarns. Fill yarns are then laid transversely and alternately, above and below the main tension yarns. The construction gives greater dimensional stability to the belt and does employ a "beam" effect for better load support.

The yarns used are much thicker than yarns in conventional fabrics. Further they are locked together by means of another series of lengthwise yarns known as the binder warp system. The binder warp system locks the tension and fill cords tightly together creating a belt which is unusually tough, and which has exceptional tear and impact resistance, as well as fastener and bolt holding ability.

Fenner Dunlop's "fiber of choice" for mining belt constructions is polyester due to its high modulus, resistance to water and mildew and its exceptional chemical resistance. It offers higher unit strength and unusual resistance to abrasion, cutting and tearing.

Polyester filament, as well as, chopped polyester staple fibers are employed in the manufacturing of highly engineered yarns - each designed to provide optimum performance within that portion of the carcass construction where it will serve.

SUPERIOR ABUSE RESISTANCE

Mine Wearlok®'s impact resistance is up to three times greater than that of conventional plied belting, while rip and tear resistance is improved up to six times in some constructions. This greater abuse-resistance means the belt will not be easily damaged in the conveying and loading of large lumps. As a result, the belt will last longer in rough service.
