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. Apron/slat conveyors are used primarily in material handling applications for moving large, heavy objects including crates, drums, or pallets in heavy-industry settings such as foundries and steel mills. The slats are not interlocked or overlapping. Slat Belt Conveyor/ApronĪpron/Slat Conveyors use slats or plates made of steel, wood, or other materials typically mounted on roller chains to convey product. Some of the uses of powered roller conveyors are food handling, steelmaking and, packaging. Various drive types include belts, chains/sprockets, and motorized rollers. Powered roller conveyors are used primarily in material handling applications that require the powered conveyance of the product. Key specifications include the drive type, roller diameter and material, and the axle center dimension. Powered Roller Conveyors use powered rollers mounted in frames to convey products. The conveyors can be straight or curved depending on the application and available floor space. The rollers are not powered and use gravity, if inclined, to move the product, or manually if mounted horizontally. Roller conveyors are used primarily in material handling applications such as on loading docks, for baggage handling, or on assembly lines among many others. Key specifications include the roller diameter and axle center dimensions. Roller Conveyors use parallel rollers mounted in frames to convey product either by gravity or manually. Belt conveyors can be troughed for bulk or large materials. The conveyors can be operated horizontally or can be inclined as well.

Belt conveyors are typically powered and can be operated at various speeds depending on the throughput required. Transporting a heavier load means a thicker and stronger construction of conveyor belting material is required. Common conveyor belting materials include rubber, plastic, leather, fabric, and metal.

The belts themselves can be made from numerous materials, which should correspond to the conditions under which the belt will be operating. Power is provided by motors that use either variable or constant speed reduction gears. The conveyor belting is supported by either a metal slider pan for light loads where no friction would be applied to the belt to cause drag or on rollers. Usually, one or both ends have a roll underneath. The belt is extended in an endless loop between two end-pulleys. Types of Conveyorsīelt Conveyors are material handling systems that use continuous belts to convey products or material. They’re used for reversing the direction of a conveyor. Center drives are not always at the actual center of the conveyor, but somewhere along its length, and are mounted underneath the system. A head or end drive is found on the discharge side of the conveyor and is the most common type. Drive Locationĭrives can be located in different places on conveyor systems.

Frames can be straight, curved, z-frames, or other shapes. Frame Configurationįrame configuration refers to the shape of the conveyor frame. This attribute applies to bucket, pneumatic/vacuum, screw, vibrating, and walking beam conveyors. It is often given as a volume per unit time, for instance, as cubic feet per minute. Throughput measures the capacity of conveyors that handle powdered materials and similar bulk products. Rated speed applies to apron/slat conveyors and drag/chain/tow conveyors as well. while powered roller conveyors described the linear velocity in similar units to a package, carton, etc. Conveyor Belt System Speed/Rated Speedīelt conveyors are typically rated in terms of belt speed in ft/min. Maximum Load CapacityĪssociated with Load Capacity per Unit Length, this value can be stated for fixed length, purpose-built conveyors. Manufacturers will offer this attribute in cases where the conveyor will be built to a custom length to permit users to determine loading margins. Important Conveyor Systems Specifications Load Capacity per Unit Length These material handling systems come in many different varieties to suit the different products or materials that need to be transported. While there are many different kinds of conveyor systems, they usually consist of a frame that supports either rollers, wheels, or a belt, upon which materials move from one place to another. They may be powered by a motor, by gravity, or manually. Conveyor Systems are mechanical devices or assemblies that transport material with minimal effort.
