Belt Conveyors

A reliable source for Conveyor System information and leading Conveyor System Companies & Manufacturers.

Belt conveyors are devices that transport materials, supplies, and other objects from one place to another within a facility while reducing the time, energy, and costs required. Belt conveyors provide an efficient means for many industries to transport heavy and bulky materials, boxes, and their manufactured items across production floors. Belt conveyors may function independently or as part of a larger system. Read More…

Belt Conveyors The most common of conveyors, the belt conveyor is a style of material handling equipment which assists in moving materials with irregular surfaces. It is also employed for small items and bags of product that would sag between roller conveyors or chain conveyors.

How Belt Conveyors Function -

Belt conveyors consist of pulleys (also known as drums) along with a continuous loop of belt material. A belt is stretchy, thick, and durable. Belt conveyors are motorized and powered by an electric motor. The conveyor belt moves when the pulleys on both sides of the belt start working. The motors of these pulleys are given electric current, which makes them move with the same spin and speed, which results in the belt also moving between both of the pulleys.

Conveyor Belt

Rollers are sometimes placed under conveyor belts if the objects are heavy or bulky. The rollers support the conveyor belt to more easily carry the load. Conveyor belts may feature various pulleys, most notably the drive pulley and the idler pulley. The powered pulley is known as the drive pulley, while the unpowered pulley is called the idler pulley.

Belt Conveyor Components -

Below are the components of a standard belt conveyor:

  1. Head Pulley -

    • Head pulling is the pulley force that drives the conveyor.
    • The head pulley is located at the discharging end of the conveyor and has the largest diameter of all pulleys that may be found in a belt conveyor.
    • The head pulley is connected to an actuator and an electric motor.
    • The head pulley features a “rough jacket,” or legging on its outside which is used to increase traction with the belt.
  2. Tail Pulley -

    • The tail pulley is located at the loading end of the conveyor belt.
    • The tail pulley functions to direct the belt back to the head pulley.
    • A tail pulley sometimes features a series of wing shapes which helps in cleaning the belt by promoting the fall of loose materials before they can accumulate below the belt.
  3. Idler Rollers -

    • Idler rollers are placed along a conveyor belt’s length to support the load and the belt.
    • Idler rollers prevent sagging, promote belt cleaning, and help align the belt.
    • There are many types of idler rollers, including troughing idlers, rubber disk idlers, screw idlers, and trainer idler rollers.
    • These various types of rollers are used for different functions for conveyor belts.
  4. Belt -

    • The selections of a belt’s design and a belt’s material are the most important choices of a belt conveyor.
    • Conveyor carcass is a belt component and is also known as the skeleton of the belt.The main function of conveyor carcass is to provide support, stiffness, and tensile strength to the belt. Conveyor carcass is made up of steel cord or textile ply. Textile ply could be aramid, polyamide, or polyester.
    • Belt exteriors are made of flexible rubber or PVC (polyvinyl chloride) thermoplastic.
    • Belt material should be corrosion-, heat-, flame-, grease-, and weather- resistant.
    • The top side of a conveyor belt could be smooth, corrugated, or cleated depending on its application.
    • Various plastic materials such as PVC, PU, and PE have traditionally been used for belts in the food industry. Today, plastic belts are also in demand elsewhere because they are easy to maintain and resistant to acids, chemicals, and contaminations.
  5. Frame -

    • The frame of the conveyor belt varies according to the type of load, the height of the machinery it services, and the distance covered by the belt.
    • Aluminum extrusions are typically used as belt conveyor frames for applications featuring lightweight operations.
    • A calculated and sensibly-designed frame can reduce system failures.
Components of a Conveyor System

Types of Belt Conveyors -

There are eight types of belt conveyors based on their design and function. These are:

  • Modular Belt Conveyors -

    Modular belt conveyors feature chains of interlocking plastic pieces that help in its movement around corners and bends. This belt is useful for conveying various products easily, and damage from sharp objects is very unlikely based on the material used to construct it. Additionally, a modular belt conveyor can be cleaned easily thus making it suitable for food production.

Curved Conveyor Belt
  • Slat Belt Conveyors -

    Slat belt conveyors use slats or plates on roller chains to transport goods. Slat belt conveyors are used to transport heavy objects that are not suitable for standard belts.

Slat Conveyor Belt
  • Portable Conveyors -

    Portable conveyors are made from lightweight materials, are adjustable to accommodate different machinery heights, and generally feature wheels so they can be easily transported. Portable conveyors are used for loading and unloading vehicles, silos and train cars. Portable conveyors are also used in the packaging industry.

  • Swan Neck Conveyors -

    Swan neck conveyors carry objects in an upward direction into a plant’s storage hopper or as part of a facility’s delivery system. These conveyors are sometimes used as a bridge in conveyor systems. Swan neck conveyors feature metal partitions that hold materials in place as they move upwards.

Swan Neck Conveyor
  • Metering Belt Conveyors -

    A metering belt conveyor is used for the separation of items and prevents their accumulation. Metering belt conveyors use sensors to access and separate items by determining an object’s width and space. Metering conveyors should be made with durable material since the separation process routinely starts and stops several times.

  • Sandwich Belt Conveyors -

    The sandwich belt conveyor is different from others as it uses two conveyors and two belts face to face. The materials that are to be transported are sandwiched firmly between the two belts.

Sandwich Belt Conveyor
  • Pipe Belt Conveyors -

    Pipe belt conveyors have a belt that rolls together to form pipes or tubes. Idler rollers help maintain their circular shape. These conveyors are best to use where space is limited, and steep inclines are required. In addition, pipe belt conveyors are used with materials where spillage is not likely.

  • Trough Belt Conveyors -

    Trough belt conveyors have a trapezoidal-form and feature edges shaped to contain materials as they move along the belt. Idler rollers are used to maintain the shape and angle of trough shapes within the belt.

Trough Belt Conveyor

Applications of Belt Conveyors -

  • Belt conveyors are used in the mining industry when taking ores from the ground, during processing, and for bulk handling applications.
  • Belt conveyors are used in automotive assembly lines.
  • Belt conveyors are also used in the airline industry to transport baggage to and from aircraft.
  • Belt conveyors are used in food handling, power generation, civil, and construction industries.
  • Belt conveyors are also used in warehouse packaging.
