A belt containing steel cords, the steel cords containing strands made of steel filaments wherein the largest diameter filaments are at least intermittently positioned at the radially outer side of the steel cord. Such a configuration can be obtained by using steel cord constructions wherein the thickest filaments are positioned outside of the steel cord which is contrary to the current practice. In a further embodiment the largest diameter filaments fill up some or all of the valleys of the strands at their radially outer side. These monofilaments thus have the same lay length and direction as the strands in the steel cord. The advantage of putting the largest filaments at the outside is that they will break first and thus will be readily detectable by electrical, magnetic or visual means. In this way a belt is provided that can be monitored easier and more conveniently than prior art belts.

An inspection device is provided in which X-rays are radiated in a fan-like shape with respect to an extension direction of steel cords, are transmitted through a conveyor belt, and reach an X-ray line sensor. A control device makes an X-ray generator and the X-ray line sensor move in a fixed relative position at a certain speed within a certain movement range in a direction parallel with a plane and orthogonal to an extension direction of the steel cords. The control device generates two-dimensional image information on the basis of an X-ray transmission signal obtained each time the X-ray generator and the X-ray line sensor move a unit amount equal to a pixel pitch of the X-ray line sensor. The control device detects measurement information relating to the conveyor belt and the steel cords on the basis of the obtained two-dimensional image information.

Provided are a conveyor belt further enhancing the durability of loop coils embedded in the conveyor belt so as to detect vertical tears in the conveyor belt; and a belt conveyor system using the conveyor belt. A conveyor belt includes a core layer having a plurality of metal cords extending in the belt longitudinal direction arranged in parallel in the belt width direction; an upper cover rubber and a lower cover rubber disposed so as to interpose a core layer from above and below; a plurality of loop coils embedded at intervals in the belt longitudinal direction in the lower cover rubber; and protective layers being disposed between the core layer above and each of the loop coils below and embedded in the lower cover rubber at intervals in the belt longitudinal direction.

A conveyor belt including a carry cover layer, a reinforcement layer which is situated below the carry cover layer, and a pulley cover layer which is situated below the reinforcement layer, where the reinforcement layer is comprised of steel cordage and rubber matrix, and wherein the rubber matrix includes zinc oxide in an amount greater than 5 phr and a cobalt derivative in an amount of 1 phr or greater. In some cases, the rubber matrix includes zinc oxide in an amount of 11 phr or greater, or even in an amount of 16 phr or greater. In some cases, the rubber matrix includes the cobalt derivative in an amount of 2 phr or greater, or even in an amount of from 3 phr to 4 phr. In some aspects, the rubber matrix is devoid of lead oxide.
