HINDUSTAN All-nylon Fabric Conveyor Betting meets high performance specifications owing to its integrated construction. its flexibility allows it to be used for practically every application in the transportation of bulk materials. However large the quantity, HINDUSTAN Al-nylon Fabric Conveyor belting is able to achieve higher speeds over longer distances than other belting systems. All-nylon HINDUSTAN betting has a longer life and better performance in terms of cost per tonne of material conveyed.
1.Higher Tensile Strength
The high breaking strength of HINDUSTAN All-nylon fabric belts has enabled major rationalization of the traditional cotton/cotton belt range to be achieved. Thus two plies equal the strength of five plies of cotton fabric.
The adhesion of HINDUSTAN Nylon Belting is nearly double than that of cotton reinforced belting due to the chemical bonding between cover to ply and ply to ply.
3. Complete Rot Resistance
Eliminates problem of fabric deterioration where wet material is being conveyed.
4. Reduced Belt Weight
HINDUSTAN Nylon Belting is easier to handle as it is comparatively lighter than equivalent all-cotton belts due to reduced number of plies and their lower weights
Straight Ply Construction
This consists of straight laid plies extending across the width of the belt.
Stepped Ply Construction
This consists of an additional rubber cushioning in the center of the belt. A gap is left in first ply (1 step) or in first and second piles (2 steps) on carrying side and that gap is filled with extra rubber cover to improve transverse flexibility.
Reverse stepped Ply Construction
This is just reverse of one stepped ply construction. Ply gap remains on the sides and is filled with extra rubber where more flexibility is required on edges. Such belt has been designed for submerged ash handling installation in the boller plants, that operates under water in a quenching trough. The thickness of rubber cover on back (i.e. bottom) is kept at 3.0/5.0 mm and on face (i.e. top) at 1.5/2.0 mm for such type of belt. The reason being that the belt is dragged along the bottom of the quenching trough due to which the wear and tear on the bottom of the belt is higher than the lop. This belt is offered in cottom fabric 32oz. duck in 'Heat Resistant' and ‘H-Tex` cover grades in 4/2, 5/3 and 6/4 reversed stepped plies.
Breaker Ply Construction
This consists of 'leno weave' breaker that is laid over the carcass with cords running transversely across the belt to provide protection against longitudinal impact breaks and may be included in the top and or bottom covers. The breaker fabrics are also used in pairs where they are laid on opposing 45° angles for extra severe impact protection. The processed breaker adds about 1 mm to the belt thickness.
Piles may be skim coaled where service conditions are severe. An extra thickness of rubber coating may be inserted between the piles for improving inter-ply additions and or heat impact cushioning.
HINDUSTAN All cotton conveyor belting is supplied in moulded edges to protect against edge wearing and prevent ingress of moisture, while all nylon conveyor belting can be supplied both in cut edges as well as in moulded edges. However, H.I.C. recommends a cut-edge construction due to complete rot resistance of the all-nylon belting.
From 150 mm to 2400 mm as per IS:1891 (LATEST) In open or endless length as per customer's requirements.
Hindustan All-Nylon Conveyor Belts are designated to indicate the minimum full thickness tensile strength and the number of fabric plies in the belt, for eg. All-Nylon 315/3 represents a belt having full thicknesstensile strength of min. 315 KN/M width, incorporating 3 piles of fabric.
|Belt Designation||Maximum Allowable working tension (vulcanised Splice)||Maximum Belt Width (mm) for Adequate Load Support (Material Bulk Densiity in Kg./m³)||Maximum Belt Width (mm) for Adequate Troughing (Angle of Picking Idlers)||Nominal Carcass Thickness||Nominal Carcass Weight|
|Type||Rating||KN/m||Upto 800||Upto 1500||Upto 2500||20°||35°||45°||mm||Kg/c.m. width/m.|
|GENERAL DUTY TYPE A||200/2||20||650||500||400||300||300||350||2.1||0.019|
|HEAVY DUTY TYPE B||250/2||25||650||600||500||400||450||500||3.2||0.030|
|EXTRA HEAVY TYPE C||500/4||55||1400||1200||1050||500||500||650||6.3||0.061|
The above represents the standard range of HINDUSTAN Conveyor Belting. However, other constructions can be exclusively designed and manufactured against specific requirements. The values given above are approximate and should only be taken into account for estimating the total weight and thickness of the belting. In the light of technological development, HIC reserve the right to alter the specification parameters without notice.
The rubber cover should be selected wisely by taking in to the account the type of material to be handled and the operating condition of the belt."Hindustan" Rubber Conveyor Belting is available in the following grades.
