Screw conveyors in modern industry are often used horizontally or at a slight inclination as an efficient way to move semi-solid materials. These can have a greater pitch spacing, resulting in a higher capacity without an increase in rotation speed. They usually consist of a trough containing either a spiral coiled around a shaft, driven at one end and held at the other, or a Shaftless Spiral, driven at one end and free at the other.

In the last decade RAJ has expanded into the area of pneumatic conveying systems and now offers a range of solutions using this technology. We can engineer and supply lean phase and dense phase systems for the transportation of products such as powders, granules, grains and flakes or extraction systems for paper and similar waste products.

A bucket elevator, also called a grain leg, is a mechanism for hauling flowable bulk materials (most often grain or fertilizer) vertically.

Bucket Elevator Consist of:

1. Buckets to contain the material;
2. A belt to carry the buckets and transmit the
3. Means to drive the belt;
4.

Accessories for loading the buckets or picking up the material, for receiving the discharged material, for maintaining the belt tension and for enclosing and protecting the elevator.

Conveyors are used as components in automated distribution and warehousing. In combination with computer controlled pallet handling equipment this allows for more efficient retail, wholesale, and manufacturing distribution. It is considered a labor saving system that allows large volumes to move rapidly through a process, allowing companies to ship or receive higher volumes with smaller storage space and with less labor expense.
