What is Conveyor Belt?

Conveyor is derived from convey. Belt is product name used to transmit power from one machinery shaft to second or more than two unpowered idlers shafts. Industrial Conveyor Belt Types primarily functions delivering products (unpacked & packed).

The different types of belts, mainly includes Conveyor Belt, Transmission Belt, Timing Belt & V Belt. They are sub divided in different categories subjected to their usages and material used to manufacture.

These belts are made of different materials which includes rubber, kevler thread, cotton or nylon thread, nylon sheet, polyurethane material, Teflon, Neoprene, Nitrile, Polyester, Leather and others. The term “Conveyor Belt” typically means a belt which transport product from one place to another using different machines call “Conveyors“.

Conveyor Belt Specification

These Conveyor are one or more than one layers of different materials pressed and fabricated together for industrial requirements. Few Rubber conveyor also uses steel cord wire for heaviest load carrying in coal, paper, mining industries.

Belt’s maximum width options are 4000mm wide with unlimited length. On the other hand, minimum thickness starts from 0.10mm to 10mm in PVC and PU and 3mm to 100mm in rubber conveyor.

The longest conveyor system in an airport is the Dubai International Airport baggage handling system at 63 km (39 mi) – Source: Wikipedia

Types of Conveyor Belt

Different industrial applications require different type of belting, elaborated in this detailed reading. Some machines or products need rough surface and other may require top side pattern or plain mat polish.

Light weight PVC Conveyor Belt

Generally, all conveyor belts are light weight (PVC & PU only). Light weight belts are used in Textile, Pharmaceuticals, Printing & Packaging, Food, Confectionery & Baking, Soap, Molding.

PU Conveyor Belt

PU or Polyurethane Conveyor belts are manufactured with properties that bear more heat and work under different heating & cooling environments. The best example for this is cooling tunnel in chocolate manufacturing machines.

Food Conveyor Belt

Food Belts convey unpacked food items including chewing gum, biscuits, snacks, cakes in industries. Here unfinished products directly touches to food item. These cold or hot products can absorb chemical properties from belt. Food Regulation applies to Conveyor Belt. This is reason Companies like Habasit, Siegling, Ammeraal and other manufacture these belts from food grade material to ensure FDA food regulation and HACCP production concepts.

Rubber Conveyor Belt

Rubber Conveyor Belts are manufactured with high quality thick rubber layers and inner layers of high tensile thread. These belts are used on heavy loads including mining industries, glass manufacturing, paper mills, crushing & recycling industries.

Sub Types From Belt Conveyor Types

Vacuum Belt Conveyors

Did you see holes in belt? Some application require fix transportation. Usually in Textile Cloth printing, Paper Packaging, Pharmaceuticals and few more. This way, Manufacturers and workshops makes holes of different dimensions & designs at your belt.

Sidewall Conveyor Belt

Purpose of sidewall conveyor is to convey maximum items. Typically used where vibrators transfers finished or raw item to belt. It helps industrialists to save their time and get maximum benefits within same time. Comparatively it could cost little higher but is effective as well.

Flaps Conveyor or Cleats Belt

Today’s manufacturing environment has been changed in various aspects. Cleated Conveyor or Flaps belt provides solutions to lift products upside.

These cleats are pasted & molded with machines to stick with belt to take products from lower side to upper side. All Belt including rubber, PVC & Polyureathane are fabricated to do this job.

Flaps or cleats designs are different in height & width depending upon industrial requirements.

Inside V Belt

Inside V Belts are those where V Belt pasted in driving side i.e., inner side of belt. Some industrial applications uses pulleys, rollers & shafts with V designed cut. Pasted V adjusts in them to avoid horizontal misalignment & travel.

Bucket Conveyor Belt

Bucket Conveyor are of two types

1) plastic molded buckets fixed with nuts and bolts

2) Conveyor material flaps and sidewall fabrication
(shown in picture).

Both perform same tasks to let product do not slip from sides and incline with maximum efficiency.

Modular Conveyor Belt

Modular conveyor belting are those used to drive at turning machine. Regular conveyors are straight but modular belts are designed to turn. Companies cut these belts width in degrees within maximum possibilities. To turn at more degree, refer to plastic modular belt.

How to clean Belts?

Companies have designed scrappers to clean belt effectively & efficiently. Comparing to traditional hard scrappers. These do not damage belt.

Types of Conveyor Belt Jointing

Advancement in industries lead to utilizing maximum from the minimum. In past, the only jointing or fabrication process was stitching. Later on, They moved to overlapping, than overlap splicing. Presently Finger Jointing, Overlap Finger Jointing, Crossed Overlap finger joint has take place of old technologies. It saves time and energy.

Which Belt is for me?

Selection of right belt can be complex decision for nontechnical. Belting made with material are as important for the lifespan as air for human. Wrongly selected belt could cause downtime, monetary loss, application failures.

Uses of Conveyor Belting

If you observe, there is no industry where you don’t see belt. Especially conveyor belt are used in different industrial segments. They are used in crops and also in processing of those cropped vegetables washing.

Agriculture Fruit & Vegetable Snacks Pharmaceuticals Peat Processing Dairies
Automotive Furniture Soap Poultry Packing Confectionery

Comparison in PU / Polyurethane &  Polyvinyl Chloride / PVC Conveyor Belt

PVC Conveyor Polyurethane Conveyor
Sticky Non-Sticky
Average Price High price
Oil Absorb Oil Proof
Non Food Use Food Usages
Non FDA FDA license required
Non International standards International Standards
Various Jointing Possibilities Few Jointing Possibilities
Big list of manufacturers Small List of manufacturers
Limited Applications Unlimited Application
Can not be used on PU Application Can be use on PVC Applications
  1. PU Belts are non sticky on PVC Conveyor are sticky. Using PVC on food application results in product damages.
  2. PU Conveyor are priced above average PVC Belt Conveyors.
  3. PVC absorbs oil and results in slippages. Polyurethane Belts are oil resistant and do work in oiling industries better.
  4. According to international FDA food law, manufacturers are bound to use PU Food Belts for food applications. They can not use Non Food Belts.
  5. Companies need FDA Licence to produce, launch, market & sales. No licence required for PVC Conveyor Belting.
  6. PVC belts are manufactured worldwide without any standards. Their applications are not linked to human health. For PU Belts companies need to follow international standardization laws.
  7. PVC belts can be jointed in overlaps, lacing & finger. PU are limited to Lacing & Fingers Joint.
  8. Even in small countries you may find manufactures but PU Belt manufactures are few in few countries.
  9. PVC belts are limited to be used in non food applications. PU are universal belting to be used on both food and non food industries.
  10. Somehow, PVC can be used on industries require PU but it do not give standard life span. From experience, in wood industries PVC gave life of 3-4 months (transporting heated material) and PU Belts giving life more than 10 months.
