There is also a substantial dimensional commonality as well. However, it makes sense to determine it before constructing the conveyor. The belt of the conveyor always experience a tensile load due to the rotation of the electric drive, weight of the conveyed materials, and due to the idlers.

Once the head pulley is sized, all other pulleys in the conveyor are derived from the following relationships: This design is distinguished by high wear resistance and has become the industry standard. Three positions need to be taken into account:.
This is recommended for free-hanging stretches longer than mm. For inclined belts, those from level to 17 degrees, the belt geometry and steel clearances were precalculated and tabulated. The geometry of the pulley terminals was pre-established to provide for proper clearance and, belt alignments for the belt return.
Structural supports for terminals, take-ups and intermediate sections. Therefore, this solution is frequently used with smaller workpieces and bulk goods.
This T1 force determines the belt selection parameter. We can of course equip the belt conveyors with belt supports ex works. Side of flow direction The convveyor on which the drive is attached. Fastening plate The following supports are primarily intended for conveyor set up on an even level. Conveyor length is approximately half of the total belt length. We could not find sufficient cost justification, or a rational commonality pattern to include drives in our standardization program.
The conveyor belt calculations methodology discussed in the article is to be used only desgn the guidance on calculating the initial conveyor design parameters; the final desigj must be validated by using the FEA or other similar tools before building the prototype. Pp is in KW. This makes it very easy to install them in machine environments. Tail snub pulley —Two or three diameters smaller than drive pulley.
Belt Conveyor Design
The simplest desgin consists of a support made of item profile over which the conveyor belt is drawn directly. The following items are left for the standardization program: A simple conveyor system may look like below:.
The sandwich panel is used to ensure good belt support for larger conveyors. Drive snub pulley —Two diameters smaller than drive convehor.
Pulley assemblies including shafts and bearings. Charts and tables then give him optimum head pulley and bearing sizes, and frame and pulley geometry for any given angle of conveyor inclination, as well as bearing center dimensions. Take-up pulley —One diameter smaller than drive pulley. This allows you to use the entire range of item products in order to integrate the elcom belt conveyors into into your frames. The most commonly used conveyor pulley is the standard welded steel pulley, which is manufactured in a wide range of sizes.
Belt Conveyor Design
Once the head pulley is sized, all other pulleys in the conveyor are derived from the following relationships:. This design is implemented through the combination of a drive pulley and two convryor pulleys. They are available also as purchased elements from equipment suppliers. We vesign a metallurgical test for every possible mineral type and treatment. Again, the rubber manufacturers have standardized, either by agreement through industry associations, or by following the leader and providing competition.
Zero-speed switches and other safety devices, scrapers, plows, and guards have been standardized by our company and most other engineering organizations. According to our experience, these are not sufficiently used by the mining industry to make any standardization worthwhile.
