89 Belt Tension Calculations W b =weight of belt in pounds per foot of belt length. When the exact weight of the belt is not known, use average estimated belt weight (see Table 6-1) W m =weight of material, lbs per foot of belt length: Three multiplying factors, K t, K x, and K y, are used in calculations of three of the components of the effective belt tension, T
Steel scrapers can be bended (in a L- or U-shape) or welded (T-shape). Decisive factors for our advising technicians are: capacity, type of bulk goods, the situation on the spot as well as the proportion between prices and quality. With the help of the calculation modules for conveyor chains you can calculate your capacity issues on your own.

Submerged Scraper Conveyors (SSCs) also known as Drag Link Scrapers/De-Ashers, are commonly used for the removal of Boiler Bottom Ash (BBA) from coal-fired boilers. From a materials handling point of view the SSC therefore performs the functions of BBA collection, dewatering of BBA, and controlling the rate of discharge into downstream systems.
The following method is used to determine the tension at any point along the conveyor: 1. Calculate the length correction factor. 2. Look up the mass of moving parts in Table 10. 3. Calculate the mass of the load from the design capacity and the belt speed. 4. Calculate the maximum effective tension under constant speed operation.

A scraper conveyor is a type of flight conveyor. It consists of a trough in which a continuous driven chain with flights is running. The flights are scraping the material over the bottom of the casing. The material is moving forward to the discharge point The design is ideal for slower transportation speeds over short distances, on moderate inclines, or even under water.
