Advantages and Construction

Higher Adhesion Levels

The SFR belts have higher adhesion level compared to conventional belting available because of its special chemical bonding coupled with mechanical locking characteristics between cover to ply and ply to ply. These characteristics help to eliminate cover peeling & increase edge wear resistance, carcass consolidation and total elimination of ply separation.

Lower Self Weight and Higher Ply Strength

The use of synthetic filament provides higher ply strength than conventional belting and therefore, the SFR belts can meet high tension requirement using less number of plies. This construction feature of Phoenix SFR carcass has advantages like low drive power requirement and higher idler life.

High Resistance to Impact and Mechanical Damages

Higher adhesion levels improve belt consolidation, thereby providing high impact resistance and eliminating cover stripping/gouging.

Improved Troughing and Higher Capacity Utilisation

Higher transverse flexibility of the SFR belts as compared to conventional belts contribute to the users and conveyor designers the advantage like deep troughing of carcass, which increases volumetric transfer capacity and improves belt training at higher speed.

High Longitudinal Flexing Properties

The specially designed SFR belts with comparatively thin carcass renders effective longitudinal flexibility for negotiating over smaller pulleys and for reduction of flex fatigue strain on the belt.

Standard Belt Construction

A conventional rubber conveyor belt consists of cover rubber & carcass made up of skim coated reinforcing fabric.

Cover Rubber

It protects the carcass from external abrasion & impact injuries. The covers are also designed to resist adverse service conditions.

Different cover grades are available depending on the application:

Carcass

It provides the body to a belt. It is the tension & strength bearing member consisting of different textile materials namely Nylon and Polyester. The carcass is made of a number of plies bonded together with rubber compound specially designed to withstand rigors of application.

Polyester-Nylon (EP) fabric conveyor belt has the following advantages over Nylon-Nylon (NN) conveyor belt:

• General purpose
• Heat resistant
• Fire resistant
• Oil resistant
• Abrasion resistant
• Chemical resistant, etc.

Reference Elongation (%) Graph for EP and NN

• Low elongation
• Short take up
• Better moisture resistance
• Low creep because of higher modulus

Edge Construction

The SFR belts are supplied in moulded edge/cut edge constructions. Synthetic fabric is rot and mildew resistant and therefore making it possible to manufacture belts in any edge construction as per requirement.

Rubber Skim Coat

A thin film of rubber layer placed in between the plies enhances the anchorage of rubber to fabric to facilitate the flex life augmented by elasticity. It further protects the carcass from impact damage & moisture ingress.

Breaker Fabric

Breaker fabric is recommended for critical application. It is placed between the cover and the carcass to improve additional anchorage through locking and to resist cover against gouging, stripping and tearing. It finds particular application where impact due to fall of lumps from greater height is experienced.

Cover Rubber

Standards Applicable

Conveyor belts manufactured by us conforms to IS : 1891 (Parts-I, II, III, V) and also to BS 490 (Part-I) DIN, Canadian Bureau of Mines, AS, JIS, MSHA, SANS and various other international specifications.

Range of Products

Width

Conveyor belts are offered in widths from 550 mm to 2400 mm. For lower width, i.e. 300 mm to 550 mm, we provide belts in equal length with cut-edge construction.

Tensile Strength & Type

Conveyor belts are manufactured in two types viz. heavy duty and extra heavy duty and such types are selected on the basis of various operating conditions like load support characteristics, impact, troughing angle, belt fatigue, etc. We are in a position to manufacture SFR conveyor belting of tensile strength up to 3000 kN/m and up to 9 ply construction (however, the standard range of belting upto tensile strength of 2500 kN/m is indicated in the belt selection tables).

Cover

Grades M-24 & N-17 are manufactured for general purpose belting conforming to abrasion loss characteristics as per IS-1891 when tested in line with DIN 53516.

Grades IS T1, IS T2, ultra heat resistant both are manufactured for various typical heat resistant applications.

THE SFR belts with fire resistant (FR) grade of rubber covers are manufactured suitable for use in open cast, underground mines, thermal power stations, especially

where fire hazards exists. Special grades like oil resistant, superior abrasion resistant, chemical resistant, energy optimised belts (EOB) are also within standard range of products.

Cover Element : CoverRubber

Minimum Pulley Diameters (to DIN 22101)

The pulley diameters in a belt conveyor system depend on the design, on strains and on the type of splice of the conveyor belt.

The minimum pulley diameter (DTr min) Gr A for group A pulleys can be roughly determined by utilizing the thickness value of the tensile member in the belt i.e. dGK as follows:

A pulley diameter so obtained shall be rounded up to the next higher standard pulley diameter (see tables below).

(Dtr min )Gr A = (Material Characteristic Calue) (dGK)
Tensile Member Material in Belt Longitudinal Direction	Material Characteristics Value
E (Polyester)	P (Polyamide)
108	90

A pulley diameter so obtained shall be rounded up to the next higher standard pulley diameter (see tables below).

Testing

Our laboratory is equipped with the most modern testing facilities to meet excellence in product quality and international standards right from raw material to finished product. Some of the important facilities include:

Rheometer

Rheological behaviour of 100 per cent batch of rubber mix is studied prior to release for production. Cure rate index, plasticity and optimum cure time are determined by this machine.

Universal Testing Machine

Equipped with printer 10T tester is used for determination of tensile strength and elongation.

Drum Friction Testing Machine

Drum friction test rig attached with different gadgets is used to determine the fire resistance behaviour of conveyor belt.

Abrasion Testing Machine

Resistance to abrasion behaviour is determined by this machine.

Electrical Resistivity Tester

The antistatic property is determined by ring electrodes.

Multi Cell Ageing Oven With Microprocessor Based Temperature Controller

It is used to determine the ageing characteristics of finished products.
