Product Description

Rubber conveyor belting is the cheapest system to convey bulk solid materials over any distance. It is the topic item of a conveyor system that allows the material handling. All rubber conveyor belts are composed by two different elements:

•    A central resistant carcass, which gives the mechanical characteristics to the product, as tensile strength and elongation. Two main belting families exist: textile - as shown in this catalogue - and steel cord conveyor belts.

•    Two rubber covers, named top and bottom covers, which protect the resistant carcass and characterize the belt, as described in this page. In order to guarantee safety and long life, also under hard working conditions, all type of rubber covers are antistatic and ozone protected. These pages aim to help you for the selection of the proper cover compounds according to the specific use and the characteristics of the conveyed material.
 

ABRASION CONVEYOR BELT

CL (L grade ISO 10247 - Y grade DIN 22102 - RMA II grade) - Standard abrasion resistant compound. CL is a cover rubber recommended for all ground applications and for the majority part of the materials, where resistance to abrasion is required. Conveyor belts with CL compound are suitable to handle heavy and/or abrasive materials such as gravel, stone, sand, aggregates, coal, cement, etc.
EC (D grade ISO 10247 - W grade DIN 22102 - RMA I grade) - Extra abrasion resistant compound. 
EC is a superior quality cover rubber, especially designed where maximum resistance to abrasion is required. The characteristics of resistance to cut, tear and ozone cracking, together with long duration, improve the quality of this cover. EC is expressly recommended for steel works and iron mines; however, it is recommended for heavy lump ore, coke, salt, limestone too.
SC (H grade ISO 10247 - X grade DIN 22102) - Superior cutting resistance compound. SC is a cover rubber designed for specific use when the resistance to cut and tear is the most important requirement. SC also guarantees high abrasion resistance. Main applications are quartz and cullet conveyance.
 

AS - Rubber cover for extreme applications. AS rubber cover is studied to offer the maximum abrasion resistance in all the applications, where an increase in the standard abrasion resistant conveyor's service life is required. Moreover, its excellent mechanical characteristics allow a superior tearing and cut resistance, which permits its use with heavy materials, i.e. big-sized minerals, bauxite, etc. or in critical working situations characterized by atypical loading/unloading systems. AS grants and surpasses grade W - DIN 22102 and D - ISO 10247 assuring an abrasion resistance of 30-50 mm3 .

FIRE RESISTANT CONVEYOR BELT                                      

BS (K grade DIN 22102, class 2A EN 12882) - Self- extinguish product. BS is a product designed to service both underground and above ground application where safety is fundamental and fire risk is high. It is recommended in particular for coal and potash applications. BS is self- extinguish and antistatic according to ISO 340 and ISO 284 or equivalent.
TS (S grade DIN 22102, class 2B EN 12882) - Self- extinguish product. TS is a product typology designed to service both underground and above ground applications. It is highly recommended for the belt conveyors located in the back areas of the tunnels. TS is designed according to ISO 340 and ISO 284 or equivalent.
TV (V grade DIN 22109, class 4 and 5 EN 12882) - Fireproof product.
TV is a belt typology designed to work in underground applications where it is necessary that the belt does not burn  and does not
trigger centres of fire. It is commended for the belt conveyors located close to the permanenwork-stations in the tunnels. TV is designed according to ISO 340, ISO 284, EN 14973 or equivalent.
AG (K+G grade DIN 22102, class 2A EN 12882) - Self- extinguish and oil resistant product. 
AG is a nitrile rubber suitable for conveyor belts and bucket elevator systems of cereal terminals and silos. AG cover rubber provides superior resistances to vegetable oils and animal fats; it is also self-extinguish and antistatic according to ISO 340 and ISO 284, or equivalent in order to guarantee high safety to the conveyor plant.

 

OIL Resistant Conveyor Belt                              
 (G grade DIN 22102) - Vegetable oil resistance compound. OM is a cover rubber that guarantees a good belt resistance against the chemically aggressive effects due to the transport of materials with moderate oil presence, like corn, fertilizers and general vegetable oily materials. OM is expressly designed to resist the terpene of wooden chips and to convey solid urban waste materials.
OH - High oil resistance compound. OH is a premium quality cover rubber with maximum resistance to oils and characterized by low volume variations after immersion in highly aggressive mineral oils. OH is expressly realized for belts conveying materials sodden with mineral oils, as for example the mechanical manufacturing rejects.
PL - Oil and heat resistant compound. PLis a compound specifically designed to  handle  pet coke during the production process when material can reach temperatures of 120 °C. The composition based on nitrile compound assures good oil resistance, too.

TRANSITION DISTANCE

The transition distance is the length of the section between head or tail pulley and the first troughing idler. In some cases, intermediate idlers are placed along the transition distance to favour the passage of the belt from the flat to the trough shape.
These conveyor sections are the most critical points of the whole plant as the elastic performances of the belt during the time depend on them.
If the transition distance is not correctly designed, high overtensions on the edges and abnormal compressions along the central axis of the belt are generated. Such phenomena is the cause of unexpected defects, sometimes mistakenly attributed to the belt as wave on the edges and longitudinal fold of the belt carcass. According to the recommendation of the international standard ISO 5293, the calculation of the transition distance is performed in order to prevent belt centre from buckling and edge tension from exceeding 30% of the recommended maximum belt tension (RMBT).  These conditions can be respected adopting the following formula:

LT = 14,16 x V x K
Experimental trials, calculations and experiences have shown  that  average  conditions  of  tension  and compression are carried out with values of V equal to 1/2 V1 .
Nevertheless, with larger sizes there is the tendency of backward rolling of the materials, for which in most cases values of V included between 2/3 and 4/5 of V1 are assumed.
So, the value of the transition distance LT can be easily calculated for TEXTER belts in the most typical installations, with idlers of equal length, by means of the following formula:
LT  = L1 x B x K
where:
L1   = unitary transition distance
B  = belt width
K  = reduction factor depending on the working tension on the belt.
