In the United States, the Rubber Manufacturers Association (RMA) has established two standard grades of belting covers. RMA Grade 1 belting meets higher rubber tensile and elongation requirements, typically indicating improved cut and gouge resistance over the performance of Grade 2 covers. It should be noted that grade rating does not ...

The primary cleaner sometimes called the pre-cleaner or the doctor blade, is installed on the face of the head pulley just below the trajectory of the material discharging from the belt. Pre-cleaners, with low blade pressure but an aggressive angle of attack, are installed to shear the coarse grit off the carryback layer.

For applications that may require the "unorthodox" width greater than the length, type of conveyor, modular belt conveyors will achieve that feat much easier. Since they are non-metallic, easy to clean, and porous to gas and liquids, modular belt conveyors can be applied in: Food handling. Fluid handling.

A conveyor belt works by using two motorized pulleys that loop over a long stretch of thick, durable material. When motors in the pulleys operate at the same speed and spin in the same direction, the belt moves between the two. If objects are particularly heavy or bulky — or if the conveyor belt is carrying them for a long distance or ...

Too often, free-belt distance is reduced in the interest of putting the greatest load on the narrowest belt. This invariable comes at a cost of sealing system effectiveness. Manufactured sealing systems are effective at sealing and protecting conveyor systems. Learn the cons of homemade seals & the benefits of engineered seals.

Inspections. Routine maintenance inspections can extend belt and component life and improve performance by keeping minor, easily corrected problems from turning into major and costly headaches. In some of the best operations, maintenance workers routinely "walk" the conveyor system, looking for indications of potential trouble.

The basic means of support for a conveyor belt is idlers. An idler consists of one or more rollers – with each roller containing one or more bearings to ensure it is free rolling. The rollers are supported by, or suspended from, a framework installed across the conveyor stringers. Idlers are the most numerous of conveyor components, in terms ...

Secondary cleaners are defined as any cleaner located in the secondary position on the return run of the belt. The secondary position is the area from just past the point where the belt leaves contact with the head pulley to just before the belt contacts the snub pulley. This location is still within the discharge or dribble chute, allowing the ...

Conveyor Belt Delamination. Because the edge of a belt marks the connection between different components, it suffers from the usual weaknesses seen at most joints. Fraying is one of the more common causes of damage to the edge of a belt, but chapter four of Martin Engineering's Foundations explains that there are a variety of others. One of the ...

The top and bottom covers of the conveyor belt provide very little, if any, structural strength to the belt. The purpose of the top cover is to protect the carcass from impact damage and wear. The bottom cover provides a friction surface for driving and tracking the belt. Usually, the top cover is thicker than the bottom cover and more durable ...

A better action is to identify the reason why the belt is mistracking and correct that issue. If adjustments need to be made, they should be made to low-tension rollers. The amount of friction between the low-tension rollers is identified by the drive pulley and the belt. The head pulley and tail pulley should be aligned and square.

Belt Conveyor Dribble Chutes. On conveyors where the cleaning systems are positioned so the material removed from the belt does not freely return to the main material body, a dribble chute, or fines chute, is usually required. This is a separate part of the discharge chute that directs the removed carryback back into the main material flow.

As the conveyor runs, the heat generated by the friction of the belt against the skirting seal combines with the abrasive nature of the material fines to erode the sealing strip. To counter this wear, the sealing strip must periodically be adjusted down against the belt. With all edge-sealing systems, it is a good idea to round off the seal's ...
