Tubular Drag Chain Conveyors
Tubular conveyors of some sort are generally utilized where bulk materials should be shipped undercover starting with one piece of a procedure then onto the next.

A tubular drag chain conveyor is required when materials should be passed on around hindrances in your facility, either around curves or in various planes (Horizontal, vertical and slanting) without the danger of spilling material, or particle debasement. The tubular idea of the transport implies that the item won’t be influenced by anything in the encompassing environment. The round shape limits harm and friction issues.
Tubular drag conveyors are auxiliary mechanical drag chain transports working inside the limits of a pipe. In this conveyor, discs associated with articulated metal connections (chains) transfer material inside the pipe making it perfect for ultra-duty applications. The discs are produced using an assortment of materials including steel and cast iron.
Tubular drag chain conveyors are utilized in facilities taking care of powders, pulverizes, pre-blended items, squanders, wet bulk solids, sticky materials or rough synthetic substances, minerals and hot materials, for example, fiery debris (ash).

Vacuum/Pneumatic Conveyors
The essential principle of the pneumatic conveying system is to transfer suspended mass material in a moderately uniform stream from a feed or supply to a conveyance point. The use of air, provided by means of a vacuum pump or blower, makes a sufficiently high airspeed and low enough solids-to-air proportion to adequately transfer the materials. Most of the Vacuum Conveying Systems move item dependent on a time interval to the vacuum recipient. Toward the finish of the planned sequence, the release valve can open and the material passed on can release into the procedure.

There are two sorts of vacuum conveying systems. Dilute Stage Conveying and Dense Stage Conveying:
Dilute Stage Conveying: The material is entrained in the air stream and is a practically equivalent part of air and item. This technique is superb for passing on practically any kind of powder-like sugar or flour.
Dense Stage Vacuum Conveying: The material is moved in slugs inside the conveyor tubing. The material passes slower then dilute stage conveying and is a superb decision for friable item or a mix of powders.
In the spearheading time of pneumatic movement, a request was to a great extent for shipping staples, for example, grain and flour. Today, such establishments are built for a wide assortment of uses, for example, moving:
 Items in residue molecule structure (flour, bond)
 Grain type items (granulate, pellets)
 Piece items (pneumatic tube conveying frameworks)
 Blended items

Comparing Tubular Drag Chain Conveyor with Vacuum Conveyor
A tubular drag chain conveyor offers different advantages over a pneumatic conveying framework:
Energy Efficiency
The high-torque and low-speed method of activity make tubular drag conveyors more energy production as compared to pneumatic conveyors; customarily requiring a small amount of the drive.
Gentle Material Handling
Since the material is successfully caught between flights, moderately static inside the flight pocket all through the movement, the material is tenderly taken care of with at least particle debasement. This method of activity will, in general, empower these conveyors to more readily endure the impacts of abrasion than pneumatic conveyors.
Tolerance for Tough Materials
Since the material is conveyed between the flights, it is a lot simpler to pass on drowsy, sticky and effectively compacted materials within a tubular drag conveyor than in a pneumatic conveying framework, in which such materials can shape plugs.
Less Noise
A tubular drag conveyor’s little engine and moderate passing on speed make it a lot calmer than a pneumatic passing on a framework, which creates a great deal of noise from its huge fan or blower engine just as different engines all through the system. Considerably more noise is made by the irregular blasts of compacted air for the filter receiver’s cleaning framework and compression task for filling up the pressure tank in a dense stage vacuum conveying system.
Less Maintenance
In a pneumatic conveying framework, the fan or the blower, revolving valves and filter recipient (and its filter cleaning framework) all demand frequent maintenance. A tubular drag conveyor demands less maintenance since it has far fewer segments. Maintenance professionals will, very often, have to supplant the flights at intervals that rely upon the application, and furthermore limit the slack in the chain, in a perfect word about once per month. The moderate passing on speed likewise expands the tubular drag conveyor’s durability. By and large, little maintenance implies a tubular drag conveyor can work all the more reliably with little down-time and lower work costs as compared to a pneumatic framework.
Lower Cost
Tubular drag conveyors can incorporate twists and change planes, they can take every necessary step of a few conveyors and along these lines have a lower cost. Be that as it may, chain type tubular drag conveyors are a top-notch arrangement. They are vigorously worked for sublime unwavering quality in demanding mechanical conditions and any circumstance where up-time is crucial. Chain-type tubular drag conveyors are the last decision for individuals whose essential concern is the price tag. Individuals who pick this technique for conveying are first attracted to the innovation in light of its dust tight development, it’s capacity to pass on vertically, and through curves. In any case, the low energy utilization, and low wear and maintenance mean a lower cost of possession. At the point when the least conceivable cost of owning a bit of hardware is most significant, the best arrangement is the tubular drag conveyor.

Water/Air Proof Structure

The last and the most significant favorable position of tubular drag chain conveyor is the water/air proof structure. Items are moved inside the tubes and disconnected from the environment. It makes this sort of conveyor best reasonable for moisture-sensitive items. On the other hand, pneumatic conveyor uses air to move things and isn’t reasonable for moisture-sensitive products.

The above discussion concludes that not all drag conveyors are made equivalent. Keeping in view the all above advantages and at the point when your passing on necessities are longer separations, unique design arrangements, over various levels and planes, requiring various channel and release spots, with solidness for handling rough and abrasive material, or delicate handling for friable material, you will need Tubular Drag Chain Conveyor.
