Key specifications include the drive type, roller diameter and material, and the axle center dimension. Powered roller conveyors are used primarily in material handling applications that require the powered conveyance of the product. Some of the uses of powered roller conveyors are food handling, steelmaking and, packaging.
The slats are not interlocked or overlapping. The use of slats in heavy duty use cases prolongs the service life of the conveyor over other conveyor types that employ belts, which would wear out quicker under the exposure to heavy loads. These conveyor systems are usually powered and come in many sizes and load capacities. Ball Transfer tables or conveyors use a series of mounted ball casters to allow for unpowered, multi-directional conveyance of the product. Key specifications include the ball material and size.
Ball transfer conveyors are used in material handling applications such as assembly lines and packaging lines, among others. When positioned where multiple conveyor lines meet, they are used to transfer products from one line to another and are often used in sorting systems. Many sizes and load carrying capacities are available. Ball transfer conveyors are not powered and rely on external forces to move the product along the conveyor. Magnetic Conveyors use moving magnets mounted beneath stationary plates, tables, or other kinds of non-magnetic slider beds, to move magnetic ferrous materials, often in the form of machining scrap.
Magnetic conveyors are commonly used as chip conveyors to remove ferrous chips from machining centers. Systems can be configured to use horizontal motion , vertical motion, or combinations. They can be beltless or may use a conveying belt instead of a slider bed. Underneath the conveying belt, a rail containing an electromagnet is used to attract ferrous materials to the belt.
Because of the magnetic attraction of the product to the conveyor, these systems can also be used upside down. Bucket Conveyors or bucket elevators use multi-sided containers attached to cables, belts, or chains to convey products or materials.
The containers remain upright along the system and are tipped to release material. Bucket conveyors are used in applications such as parts, bulk material, or food processing and handling. The conveyed material can be in liquid form or dry such as sludge, sand, manure, sugar, and grain. The systems can be used horizontally or can be inclined or vertical to change levels of the delivered products. Many sizes and load carrying capacities are available depending on the application.
Chute or Trough Conveyors are material handling systems that use gravity to convey product along smooth surfaces from one level to another. Key specifications include the chute material and the physical dimensions such as length and chute width. Chute conveyors are used for scrap handling, packaging, postal service package or mail handling, etc.
Chutes are designed to have a low coefficient of dynamic friction, allowing the product or material to slide easily, and can be straight or curved depending on the needs of the application. Drag conveyors are used for moving bulk materials in bins, flights, or other attachments and can have multiple discharge or loading points.
Tubular drag conveyors use a fully enclosed system of chains to convey product in any direction. Chain conveyors use a chain, or multiple chains to move pallets or other hard-to-convey products. Tow conveyors use a towline such as cables or chains, usually in the floor or just above it, to tow product directly or to tow wheeled carts or dollies. Overhead Conveyors are mounted from ceilings that use trolleys or carriers moved by chains, cables, or similar connections.
Overhead conveyors are primarily used in material handling applications where the product needs to be hung, such as dry-cleaning garment lines, paint lines, or parts handling systems, or for cooling and curing. Various types of overhead conveyor systems configurations are available including electric track, monorail, trolley, as well as inclined or ramped. Depending on the application, the load-carrying capacity may be critical.
Most overhead conveyors systems are powered and controlled, while others are hand-operated conveyor belts. Materials for the conveyors can be metallic or non-metallic depending on the media being conveyed.
Various sizes are available depending on the load and throughput requirements. Screw conveyors , sometimes known as spiral, worm, or auger conveyors use helical elements to move materials. They consist of a helical screw element or steel auger that rotates around a central shaft, driving the work material according to the screw design and rotational direction.
The helical screw functions within a casing, trough or compartment to take full advantage of the rotational force. Manufacturers use screw conveyors to transport materials such as flakes, grains, powders, seeds, and granules. Alternatively, these devices can be used to mix, agitate or blend such materials, or to maintain solutions. They are used widely in agricultural applications, from use in farm machinery like threshers and balers to factory-based grain and crop movers.
A mini screw conveyor can also transport wet, non-flowing and caking materials that might otherwise be difficult to move, such as concrete. Other applications for screw conveyors are the conveying of various mechanical parts or to function as a bottling system conveyor. The screw can be of a paddle or ribbon design depending on the application and can be driven via a chain and sprocket, gears, or direct drive. Types of screw conveyors include bottom conveyors and centerless screw conveyors.
Bottom conveyors use multiple screws in an open trough. Centerless, or shaftless, screw conveyors do not contain a central shaft and instead consist of an empty helix. This design still moves the substrate but allows for more freedom within the casing. Materials can be metal or non-metal depending on the media being conveyed.
A conveyor belt works by using two motorized pulleys that loop over a long stretch of thick, durable material. When motors in the pulleys operate at the same speed and spin in the same direction, the belt moves between the two.
If objects are particularly heavy or bulky — or if the conveyor belt is carrying them for a long distance or duration — rollers may be placed on the sides of the conveyor belt for support. While there are numerous types of conveyor systems, all serve the same purpose of transporting materials. Some products may require a system without a belt, using only rollers or wheels for flexible movement.
However, many conveyor systems rely on a frame with a belt and possible support rollers to carry materials and products efficiently. All conveyor systems have three main components — the aluminum profile, the driving unit and the extremity unit. In a conveyor belt system, the aluminum profile consists of the frame, belt and any supports. Systems that use a belt are generally powered by a motor, though conveyor systems can also use gravity or manual force to function.
Motorized conveyor belts are ideal for industrial use as they are more reliable and efficient — the driving unit for such systems would include the motor bracket, electrical drive and any counter bearings.
Parts and functions of a new conveyor belt system might include:. Conveyor belting can be crafted from various materials, including rubber, metal, leather, fabric and plastic. Consider the conditions that your system will operate under to ensure the conveyor belting material is of suitable thickness and strength.

Modern Conveyor Belts As we entered the s, which is acknowledged to be the contemporary period for conveyor belt systems.
The Fundamentals of a Conveyor Belt System Belt conveyors consist of a drive roller powered by a drive motor with a tension roller at the opposite end moving an endless loop of the conveyor belt which rotates around them. Conveyor belts have been introduced in multiple industries, in order to speed up productivity, these industries include, but are not limited to; Construction; Conveyor belt systems can aid in carrying heavy raw materials, such as; cement, bricks and sand to a different part of a construction site.
What are the Benefits of a Conveyor Belt System? These advantages include; Able to be tailored to your specific sizings requirements and to meet your needs from the conveyor belt They use significantly less power, as opposed to rival mechanical machines Aid in production lines working efficiently and in a timely manner Increases the amount of security within an operation Considerably improves the process quality Help to free up spaces within the manufacturing area Creates a more standardised process and consistent products Over a vast period of time, the implementation of conveyor belts systems has increased as our needs for manufacturing continue to evolve.
