Rubber mats - Import export

Steel clamped or monobloc rollers mounted on pre-lubricated and protected radial ball bearings.The externally threaded shaft protrudes from only one end of the tube.In belt conveyors, they are vertically mounted in pairs at the edges of the rubber matting, with the function of restricting any lateral slipping. They are installed on self-centring stations with the same function.The technical characteristics of Series 6 rollers are those of the relative base rollers.Other finishes, see page 30.

Drums are used in belt conveyors for the handling of bulk materials, with predominant functions of activating (control drums) and tensioning (idler drums) the rubber matting. In the most challenging handling systems such as large mining or port complexes, etc., where hourly flow rates and speeds are high and the distances or differences in altitude to be reached or gained are considerable, they are further distinguished depending on the specific application: contrast drums; deviator drums; tensioning drums.

Due to the structural characteristics of the materials of which they are made, these rollers are used in belt conveyors in handling systems for bulk, humid or sticky materials, in normal, aggressive environments; operating temperature also low. As lower rollers (return) because they prevent the accumulation of material carried by the band, the field of application is specifically on the steel tubes; they thus favour linear and jolt-free running of the rubber matting. They consist of clamped or monobloc base rollers with steel tube and special anti-abrasive rubber rings pressure-aligned on the jacket.

Due to the structural characteristics of the materials of which they are made, these rollers are used in belt conveyors in handling systems of bulk materials, including sharp and abrasive, mixed size, large and heavy materials, in normal, dusty and aggressive environments. As upper rollers, their field of application is specifically in the loading areas of conveyors to protect the rubber matting from the dynamic action of falling materials. They consist of monobloc base rollers with steel tube and special anti-abrasive rubber rings pressure-aligned on the jacket.

Garland roller sets are used in belt conveyors that have to handle blunt, bulky, heavy materials. The increased containment capacity of the roller basin facilitates higher speed of transport than those of traditional stations. For upper stations in current use installations, garland sets with 3 and 5 steel or rubberised impact rollers are mounted; for lower stations, garland sets with 2 steel rollers or with scraping rubber rings are mounted. The flexibility of garland sets enables their adaptation to the material to be transported, facilitates transportation, reduces impacts on the rollers, and limits any lateral slipping of the rubber matting. The diagrams and Table 90 show the shapes of mountings of garland sets envisaged in TECNORULLI’s production programme. Other shapes may be considered on request.

They insulate the surroundings from trams, trains and undergrounds-induced vibrations by means of rubber mats, or dull them by means of tuned mass dampers. FIP INDUSTRIALE has developed a wide range of systems to reduce the effects of vibrations. In the railway, tramline and underground sectors, the use of special rubber mats under the ballast or under the reinforced concrete platforms, permits to isolate the surroundings from travelling trucks-induced vibrations. In other sectors vibrations can be dulled by means of tuned mass dampers or some types of seismic devices. TYPES: Damping mats Tuned mass dampers
