Textile/Fabric Reinforced Conveyor Belts are generally composed of the following components:
It protects the carcass mainly from impact damage, wear, cut, gauge caused by the material conveyed. It also protects the strength member from effect of oil, heat, flame, chemicals etc. as the case may be.
It protects fabric layers against chaffing by separating them and also provides adequate bonding between different layers of fabric. Provides certain amount of load support and cushioning effect to impact on loading.
It provides the tensile strength and body necessary to move the loaded belt. The carcass is made of a rubberized fabric plies bonded together, such as, cotton-cotton, cotton-nylon, nylon- nylon and polyester-nylon fabrics
It provides good coefficient of friction between the belt and the pulley. Also helps protect the carcass from wear and impact damage from the idlers during carriage of the material and from the material accumulated on the idlers.
Breaker fabric is recommended for applications involving high impact of material on the conveyor belt. It helps protect the carcass from the impact damage. Due to its weaving nature the breaker disburses impact force in different directions thereby resisting the effect of impact force at a particular point thus saving the carcass from impact damage.

With our strong commitment towards R&D we have developed HHR Conveyor Belts.
The HHR Belt has been specially designed to overcome the deficiencies of Conventional H.R. . Super H.R., UHR Grade Belts, such as less belt life, crack formation in cover, Ballooning of belt etc., resulting in high belt consumptions, high inventory, uncertain & frequent change-over, high spillage etc., resulting in increase in belt costs.
HHR belts avoid huge losses on account of high belt consumption, overcome un-certainties on belt/joint failure and reduce pollution by containing/stopped spillages, which are caused due to material entrapment in cracks etc.
Very hot lumpy as well as powdery material handling/conveying, e.g. clinker, sinter, burnt lime etc., where the material temp. is above 150°C, with occasional Red Hot material.
HHR is a speciality product for high heat application, hence is advised that customer should provide maximum critical information on application, enabling us to recommend suitable belt construction, if required.
Breaker fabric is recommended for applications involving high impact of material on the conveyor belt. It helps protect the carcass from the impact damage. Due to its weaving nature the breaker disburses impact force in different directions thereby resisting the effect of impact force at a particular point thus saving the carcass from impact damage.

*RMBT- Recommended Maximum Belt Tension
A. Driving pulley and pulleys exposed to high belt tension e.g. main driving pulley on the head or tail, delivery pullets under full tension, loop pulleys in the tripper, terminal head pulleys in the case of tail driving etc.
B. Snub pulleys in the return run under lower belt tension e.g. terminal tail pulleys in the case of head driving, terminal head pulleys for downhill conveying, if the terminal tail pulley is braked, snub and bend pulleys in the take-up devices.
C. Bend pulleys, for a change of direction of the belt of less than 30°
1. Add 0.15 meter to the calculated approx. belt roll diameter to arrive at wooden drum diameter.
2. Keeping in view the stability of drum in transit and installation, it is suggested that drum-width to drum height/diameter should be maintain within the ratio of 13.5.
Chevron Conveyor Belts are specially designed for the effective material handling in the applications where the angle of incline is higher (>18°) for the material to be conveyed and the the material tends to slide on a conventional conveyor belt. Chevron belts are suitable for transporting a wide range of bulk materials and also fir unit loads such as bags, bales, crates, sacks etc. Chevron achieve high conveying capacities even at inclinations of up to 40-45°.
In contrast to the profiles/cleats that are vulcanized separately on to the flat conveyor belt, the profiles/cleats on the Chevron Belt are integrally molded into the top cover of the belt during the manufacturing process. The advantage of specially designed integrally molded Chevron Belts is that the life of profile/cleat is enhanced due to low flexing/bending stress generated while negotiating around pulleys, this feature also permits the use of smaller pulley diameters.
The overlapping of the profiles/cleats assures a smooth return run and thus minimizing the damage caused, by the return idlers, to the profiles/cleats.
Incline angles achievable incline angles are dependent on the type of chevron selected and the material characteristics such as lump size, flow ability, dry/wet, shape etc.

Rough Top Belts, are available with rough pattern on the carrying side of the belt, suitable
for transportation at inclined angles of light weight materials and packages that may otherwise roll
down easily.
The belts are manufactured, with the top surface having a rough pattern widths up to 1500 mm wide in
2 or 3 plies with different rubber cover grades. The belts can be supplied with open ends as well as in
endless lengths depending on the application.
These belts are provided with cushioning and anti-slippery or anti-skid effects. Due to its coarse and soft rugged surface pattern on the top cover it gives high friction between belt and the carried load. It is suitable for transporting fragile or deform-able materials packed in bags and cartons in inclined application. These type of belts are also called as Wavy top belts.
We will solve your rough top conveyor belting challenges across applications, including package, sack, or box conveying on inclines or declines up to 35 degrees. Rough top conveyor belts cushion the load, absorbing vibrations and minimizing impacts.
The quality starts with the procurement of best suited raw materials(preferably from origin/source), tested for compliance with strict internal quality norms. The stringent internal specifications are strictly adhered to at each stage of pre and post production to ensure precisely engineered finished final product. Check and re-checks are common in production stage to make sure that there is no deficiency left at ant stage.
Quality Assurance bases on thorough technical knowledge of belting designs and efficient conveyor operations, the green/ raw belts are built under equal ply tensioning, proper laying of piles and uniform thickness maintained under adequate pressure so that finished product performs in a consistently reliable manner on account of straight running and uniform load bearing of reinforcement member.
A very good set up that ensures belt assembly with centering of piles under controlled uniform tension. The machine is also used for precise cutting/sitting of finished goods.
Of widths ranging from 500 to 2500 mm wide and in a variety of lengths provide excellent belt consolidation of optimum cure apart from giving the case and flexibility quality belts efficiently.
It is a versatile, fully computerized testing used for thickness tensile strength (FTTS), Elongation at reference load, Elongation at break, cyclic load testing etc.
It is used to predetermine processing safely. The testing gives details of compound’s important properties such as cure speed/ time, optimum cure time, viscosity, scorch time/ performance, reversion, cross linking time etc. All uncured compounds are subjected to (100%) cemetery inspection. Only after meeting the preset values, compounds are released to production department.
Abrasion/ wear resistance being one of the most critical properties of conveyor/ elevator belting is tested on this machine as per DIN 53516.
The machine is used for testing the fire resistant property of conveyor belt against friction. The machine is well equipped with load cell, temperature indicators, air circulation etc. aa per national and international standards.
The machine tests the electrical resistively of a conveyor belt. The test is essential to determine the anti static property of a conveyor belt.
The apparatus is used for testing the flame-proof property of a conveyor belt.
Equipped with digital temperature indicators, temperature controllers and plotters.
All tests are conducted at our fully quipped state of the art test lab. The R&D wings helps in development and improvement of rubber compounds in line with latest standard/customer requirements. Latest achievements of our R&D are SSHR and MEGAHETA cover grade of belting of high heat resistant conveyor belt applications. Cement and Steel sectors in particular are the most beneficiary of its crack free properties.
