In today’s economic environment, communities and businesses are always looking for new ways of cutting costs and the use of shredders provides new strategic options. There are two main purposes of shredding materials in the paper recycling process.
Firstly, by reducing the volume of material through reduction, transportation and storage costs may be decreased. Secondly, automated shredders, particularly in e-waste recycling, also liberate materials for recycling. Such equipment is offered by several vendors. Many options are available, depending upon the specific application. Before making an investment, potential buyers should understand such factors as:
The assortment of items to be recycled
Volume of throughput
Requirements of residual buyers in terms of such parameters as particle size
A flat incline belt is often used to feed materials into the shredder. The material can be placed on the belt through a variety of methods, depending on the particular operation. Material handling equipment assigned to perform this task can include grappling devices, front-end loaders, forklifts, and drop-bottom containers.
Shredding solutions of choice typically involve low speed, high torque units that slowly tear material apart, minimizing problems such as embedding metal in plastic during the shredding process.
Where large items are to be shredded versus a stream of only smaller items, a larger primary breakdown unit may be required. A second pass can be then made with a secondary shredder or granulator to further reduce particle size and facilitate the liberation of recyclable materials. Sizing screens are utilized to ensure a uniformly sized product.
Some vendors offer a single pass machine that will do both the primary breakdown and particle reduction. A variety of sorting machines can be used to sort material for maximum recovery.
