What is a Baler?
- Balers are used to compress materials such as agricultural goods and recyclable materials to achieve better material handling and storage.
- The first balers were developed for agricultural applications. Tractor balers eliminated manual raking, bundling, and wrapping of haystacks. The concept of baling is then applied to industrial and domestic wastes to save storage and transportation costs.
- There are different types of balers classified according to ram orientation and the number of strokes or cylinders. Balers can be classified into vertical and horizontal balers. Vertical balers are simpler and smaller than horizontal balers. Horizontal balers, on the other hand, are used for large scale material processing applications.
- Single-ram balers can be further classified into open-end and close-end balers. Open-end functions like an extruding machine where the scrap materials are compressed against the previous bale. Closed-end balers have a closed-door on the other end where the materials are pressed.
- Two-ram balers compress the bale from two directions. These are usually configured forming an L shape. Since the width of the opening is not limited to the dimension of the bale, two-ram balers have a faster feed rate.
- Ferrous balers are machines with two or more cylinders. Its main difference is the pressing lid that pre-presses the materials before forming it into a bale.
