Drag Chain Conveyor

• It is a connected chain device used for stimulating and moving bulk material comfortably from inlet point to discharge point.
• Drag chain conveyors, Scraper chain conveyors, Paddle chain conveyors, or En-Masse chain conveyors all possess a continuous chain to move solid material in a trough. Although each one of them has the same purpose of carrying the material, their functionality varies.
• Drag conveyors are preferred for moving materials like powder, granules, cement clinker, ash, sawdust of the mining and chemical industries, moist sludges, pellets, etc.

Drag chain conveyors are perfect for carrying dry, cold, highly abrasive, or hot materials. They have multiple applications diverging from industry to industry. Some of them are:

• Drag chain conveyors are generally used to transport coal, wood, pellets, sludge in power plants, paper mills, and waste management facilities.
• They can safely transmit food materials like dry powders & granules, coffee, pet food, fish food, recycled products, tea, grains, snacks, etc. in the Food Industries.
• They can also handle Latex, PET, plastics, recycled plastics supplies, etc. in the Plastic & Rubber Industry.
  In Timber Industries, they are used to carry sawdust, wood chips, wood pellets, etc.
• They are also used in conveying bottle caps, buttons, detergent, dust, soluble corn fiber, wax flakes, etc.

The technical features/parts for Drag Chain Conveyor vary according to their types. The following are the parts of the Tubular Drag Chain Conveyor. It is a fully enclosed chain system for carrying the products.

• Drive Unit Assembly
• Intermediate Casing
• Take-Up Unit Assembly
• Chain Link Assembly
• Chain Drive Unit Arrangement

• The principle operation of a Drag Conveyor is based on material transportation. It consists of a single or double-stranded continuous chain which is powered by a motor for pulling the material at the bottom of the conveyor.
• It also has a flight assembly attached on both sides of the chain drawn on the bottom of an enclosed housing or trough to allow material to be pulled to the outlet.
• The material is transmitted by the motion given on the bottom surface of the trough by the chain and the shear friction between the particles of the material that is transferred.
• The flights (aka paddles or scrapers) are placed at separate points, and the gaps between each paddle are sufficiently broad for providing more than one inlet.
