Essential considerations in belt conveyor design
The incorporation of a belt feeder, which meters material onto the belt from a bin or hopper is often essential in this setting. The design of the loading area must also consider the velocity at which material will hit the belt and the size of the material. Additional components such as an impact bed may be necessary to minimize belt wear.
Evaluating rules of thumb using conveyor costs
The majority of these rules are echoed below: 1. An underground mine is more economically served by a belt conveyor than railcars or trucks when the daily mine production exceeds 5,000 tons. (Source: Al Fernie) 2. As a rule, a belt conveyor operation is more economical than truck haulage if the conveying distance exceeds 1 km (3,280 ft.).
How To Choose A Mining Conveyor Belt
Conventional conveyor belts are comprised of three layers. There's the top layer, or cover, which is what the product rests on during transportation. The middle layer is also known as the carcass, which helps support the belt. The carcass tends to be made of either metal or woven fabric. Then, there's the bottom cover to complete the belt ...
