A belt conveyor is a continuous strip of material that moves over the ends of two pulleys at permanently fixed positions. It tends to be used for transporting materials and objects horizontally. The structure of a belt conveyor tends to consist of a solid metal frame that features rollers which are installed at different places on the belt. The belt covers the rollers, and it tends to be made from a rubber material.
The three predominant kinds of conveyor belts are; basic, snake sandwiches, and longer belts. The basic belt features 2 or more pulleys that are held on one continuous length of material. The belt can be moved by both; motorized and/or manual. The items on the belt are then carried in a forward motion that features very little friction as it proceeds.
Snake Sandwiches Belts
A snake sandwiches conveyor features 2 separate belts that lie parallel to one another. The belts hold the products in position while they move forward. They tend to be used for moving products through steep inclines that can range all the way up to 90 degrees. This type of belt was originally started in 1979 as a simple and effective method of moving rocks and various other types of material out of mine shafts. There were different reasons why the snake sandwich conveyor was better for mining usage.
The unique design allowed for the use of hardware and also helped take advantage of easy principles that ensured the conveyor was going to be easier if it needed to be repaired. This was huge because most of the mines happened to be located in remote areas that had limited access to parts for the machine. They make it possible to continue moving materials and products at a consistent pace over longer distances than the other types. The belts that have smoother surfaces can be cleaned easier by using a belt scraper and different plows. Plus, the design is flexible enough in order to enable the redirection of products and materials off the belt at any single point.
Longer belt conveyors have 3 units that are used to move materials over longer distances that the others. Unlike the other belts, the rollers in this particular belt can handle horizontal and vertical. Longer belt conveyors can become up to around 14 kilometers or 8.5 miles in length. Because of this, they are extremely good for use in mining operations and tend to be used for transporting materials to desolate building sites and other construction places. For example, the bottom of a mining pit.
When you are purchasing a belt conveyor, it is essential to consider the actual construction and durability of the belt. You should keep in mind that the design and material of the belt plays a huge role in its overall performance, maintenance, and overall machines life expectancy. For example, woven type belts may be designed for all purpose applications. However, they would not be a good use for heavy materials. Plus, you probably want to find a belt conveyor that has special features that would make it perfect for your company in question. Keep these things in mind when deciding on your next belt conveyor purchase.
