There are two types of tubular drag conveyors – the tubular drag chain conveyor and the tubular drag cable conveyor

The tubular drag chain conveyor gently moves bulk solid materials via a sealed tube with a drag chain pulled through it in a loop. This conveyor can move materials including fine powders, granules, and pellets in any direction and at any level around any obstacle in a factory. A tubular drag conveyor can handle friable materials like chemicals and pharmaceuticals as well as other delicate materials without particle degradation. They are also used for heavy industrial applications that depend on absolute reliability and continuous service.

The tubular drag cable conveyor works like a tubular drag chain conveyor except it uses a cable-and-disc assembly, not a chain and disc assembly, to convey materials through the conveyor. The tubular drag conveyor moves materials continuously through the tube at higher speeds than the tubular drag chain conveyor.

The conveying tubes have a diameter of 2, 4, or 6 inches, depending on a company’s application. The materials in tubular drag conveyors are transported to discharge points in these totally enclosed, dust-free conveying tubes.

A bucket elevator system is one of the many kinds of conveyor belt systems used to transport product in a horizontal or vertical direction. This system uses a continuous line of buckets attached to each other on a rubber belt to carry product from one place to another. Alternatively the buckets are attached by pins to two endless chains running over tracks and driven by sprockets.

At the end of the conveyor run, the bucket tips and the product is dumped out. Read More

Screw conveyor systems are typically used to move bulk materials as well as solid particles including sand and gravel, lumpy materials, cement, wood chips, sludge, and food grains.

A screw conveyor consists of a rotating screw powered by a motor that rotates in an enclosed shaft, or trough. The screw can be cooled by water if the material that is being handled is hot. Read More

Also called air conveyors, pneumatic conveyors, use air to move materials from one location to another. This is done by generating air pressure levels that are either above or below the atmospheric pressure to transport the materials to their destinations through tubes or pipes in the conveyor system. A pneumatic conveyor is usually extremely reliable and easy to maintain, making it an attractive choice for companies considering various conveying methods. In addition, pneumatic conveyors are capable of handling many different materials.
 
There are many different types of pneumatic conveyors. The most basic are the dilute phase conveyor and the dense phase conveyor. These systems differ by rate of speed and pressure.Read More

Chain conveyors are conveyors that use parallel horizontal chains to move materials through a conveyor system. These conveyors have tread rollers attached to the sprockets and are driven by a chain. Chain conveyors are set on the floor or they operate overhead. The material is moved from one place to another on the conveyor belt assembly. When the material gets to its final destination, workers remove it from the conveyor line. Chain conveyors are used for moving bulky materials as well as moving materials around curves.

On the plus side, chain conveyors efficiently move heavy loads at controlled speeds and they are resistant to extreme temperatures as well as contamination by substances like oil, grease, chemicals, and dirt. Read More

Vacuum conveyors are powered by vacuum pumps that are driven by compressed air and can be controlled automatically. With this type of conveyor, materials are drawn through a totally enclosed pipeline to the delivery point in a contained stream of air generated by a vacuum pump. The material moves up steep angles and can even move upside down from one place to another.

When the material container is full, the vacuum pump is stopped and the valve on the bottom opens to release the material. In vacuum conveying, no moving parts contact the material, no dust escapes, and no contamination can enter the system. Read More

The aero-mechanical conveyor is a completely enclosed, high capacity mechanical conveyor that can convey pellets, flakes, powders and granules. This type of conveyor features delivery that is free of dust contaminants. It can be used to move a variety of products including plastics, tea leaves, coffee beans, and even titanium dioxide. This type of device is perfect for transporting materials from 10 feet to 85 feet An aero-mechanical conveyor can be designed and custom-made for the materials that will be conveyed.
 
An aero-mechanical conveyor consists of a constant-diameter tube that contains a series of discs mounted at fixed intervals on a cable plus a motor that thrusts the discs through the tube at such a high speed that it creates a moving current of air in which to convey the materials. Read More
